@node Overview
@chapter Overview
@cindex overview

@command{ponysay} displays an image of a My Little Pony pony saying a message
provided by the user in a terminal, or a quote from the show My Little Pony:
Friendship is Magic (MLP:FiM). Historically @command{ponysay} was a wrapper
for cowsay, but has since version 2.1 become an independent reimplementation
of @command{cowsay}.

If a message is not provided, e.g. by piping, it accepts standard input.
The pony quoting the given message is printed on standard output.

@command{ponythink} is to @command{ponysay} as @command{cowthink} is to
@command{cowsay}.

@command{ponysay} is generally used to decorate your terminal with a random
pony from a shell start-up script. But if you know anypony else who likes ponies
you can always make screen-shots of @command{ponysay --q} executions and
communicate that way over e-mail.




@node Invoking ponysay
@chapter Invoking @command{ponysay}
@cindex invoking
@cindex options
@cindex arguments
@pindex @command{ponythink}

The format for running the @command{ponysay} program is:

@example
ponysay [@var{option}...] [--] [@var{message}]
ponythink [@var{option}...] [--] [@var{message}]
@end example

Running @command{ponysay} will print a speech balloon, @command{ponythink} will
print a thought balloon. Otherwise @command{ponysay} and @command{ponythink} is
the same thing.

@command{ponysay} supports the following options:

@table @option

@item --
@opindex @option{--}
Parse the following arguments as parts of @code{@var{message}}.

@item -h
@itemx --help
@opindex @option{-h}
@opindex @option{--help}
Show summary of options.

@item +h
@itemx ++help
@opindex @option{+h}
@opindex @option{++help}
@opindex @option{--help-colour}
Show summary of options, and use colours even if stdout is piped.

@item -v
@itemx --version
@opindex @option{-v}
@opindex @option{--version}
Show version of program.

@item -f PONY
@itemx --file PONY
@itemx --pony PONY
@opindex @option{-f}
@opindex @option{--file}
@opindex @option{--pony}
Specify the pony that should printed, this can either be a file name or a pony
name printed by @command{ponysay -l}. This option can be used multiple times to
specify a set of ponies from which one will be selected randomly. If no pony is
specified one will be selected randomly.

@cindex @command{util-say}
@cindex .png
@cindex PNG images
@cindex images, PNG
@cindex Portable Network Graphics
If you have @command{util-say} installed, you can use .png-files as the
arguments for this options.

In versions earlier than version 2.0, the if the pony were a file name it had to
include a `@code{/}'. This is not longer required and any existing pony name
supersedes file names.

@item +f PONY
@itemx ++file PONY
@itemx ++pony PONY
@opindex @option{+f}
@opindex @option{++file}
@opindex @option{++pony}
Just as @option{+f}, but it uses extra (non-MLP:FiM) ponies instead of standard
(MLP:FiM) ponies

@item -F PONY
@itemx --any-file PONY
@itemx --anyfile PONY
@itemx --any-pony PONY
@itemx --anypony PONY
@opindex @option{-F}
@opindex @option{--any-file}
@opindex @option{--anyfile}
@opindex @option{--any-pony}
@opindex @option{--anypony}
This option combines @option{-f} and @option{+f}.

@item -q PONY
@itemx --quote PONY
@opindex @option{-q}
@opindex @option{--quote}
@cindex quotes
@cindex pony quotes
By using this option, a pony will be printed with quotes from her in
My Little Pony: Friendship is Magic. The pony will be selected randomly,
unless at least one pony is added as an argument to @option{-q}. If one or more
ponies are added as an argument to @option{-q}, the pony will be selected
randomly from that set of ponies. This option requires the extension
@command{ponyquotes4ponysay}, which is included by default since version 1.2.

The argument can be a file name, but only if it ends with @file{.pony}.

@item --f [PONY...]
@itemx --files [PONY...]
@itemx --ponies [PONY...]
@opindex @option{--f}
@opindex @option{--files}
@opindex @option{--ponies}
Variadic variant of @option{-f}, meaning that all arguments added after this one
will parsed as an argument to this option. Additionally, those options are added
to @option{-f}.

@item ++f [PONY...]
@itemx ++files [PONY...]
@itemx ++ponies [PONY...]
@opindex @option{++f}
@opindex @option{++files}
@opindex @option{++ponies}
Variadic variant of @option{+f}, meaning that all arguments added after this one
will parsed as an argument to this option. Additionally, those options are added
to @option{+f}.

An important feature of this options, is that you can but it in the end of the
command line, without any argument to get a random non-MLP:FiM pony. However,
altough it is not nice, since version 3.0, @option{+f} can also be unargumented
if at the end of the command line.

@item --F [PONY...]
@itemx --any-files [PONY...]
@itemx --anyfiles [PONY...]
@itemx --any-ponies [PONY...]
@itemx --anyponies [PONY...]
@opindex @option{--F}
@opindex @option{--any-file}
@opindex @option{--anyfile}
@opindex @option{--any-pony}
@opindex @option{--anypony}
This option combines @option{--f} and @option{++f}.

@item --q [PONY...]
@itemx --quotes [PONY...]
@opindex @option{--q}
@opindex @option{--quotes}
@cindex quotes
@cindex pony quotes
Variadic variant of @option{-q}, meaning that all arguments added after this one
will parsed as an argument to this option. Additionally, those options are added
to @option{-q}.

An important feature of this options, is that you can but it in the end of the
command line, without any argument to get a quote from any pony with a quote.
However, altough it is not nice, since version 3.0, @option{-q} can also be
unargumented if at the end of the command line.

@item -b STYLE
@itemx --bubble STYLE
@itemx --balloon STYLE
@opindex @option{-b}
@opindex @option{--bubble}
@opindex @option{--balloon}
Specify the balloon style that should used, this can either be a file name or a
balloon name printed by @option{ponysay -B}. This option can be used multiple
times to specify a set of styles from which one will be selected randomly. If no
balloon style is specified a fallback style will be used.

@item -W COLUMN
@itemx --wrap COLUMN
@opindex @option{-W}
@opindex @option{--wrap}
Specify the screen column where the message should be wrapped, this is by
default 65, as with @command{cowsay}. The balloon's extra width is taken into
consideration.

If the argument is not a number, but starts instead with @code{n} (for ‘none’ or
‘no’), no wrapping is done, and if it starts with @code{i} (for ‘inherit’)
the width of the terminal is used.

@code{n} and @code{i} is case insensitive, so you may use @code{N} and @code{I}
instead. Additionally, typo correction is for QWERTY (and QWERTZ) and Dvorak is
built in to @command{ponysay}; the nearest key, either to the left or to the
right, depending on which hand is used to press the key, is also allowed.

@item -c
@itemx --compress
@itemx --compact
@opindex @option{-c}
@opindex @option{--compress}
@opindex @option{--compact}
@pindex @command{figlet}
@pindex @command{TOIlet}
Compress the message in the same way @command{cowsay} does, that is basically
without multiple spaces, and only paragraphs separations. Using this options
will mean that you cannot display @command{figlet} and @command{TOIlet} style
messages.

@item -l
@itemx --list
@opindex @option{-l}
@opindex @option{--list}
Lists all installed ponies. The ponies which have quotes, i.e. can be used with
the @option{-q} option, will be marked by being printed in bold or bright
(depending on the terminal.)

@item -L
@itemx --altlist
@itemx --symlist
@opindex @option{-L}
@opindex @option{--symlist}
@opindex @option{--altlist}
Lists all installed ponies. The ponies which have quotes, i.e. can be used with
the @option{-q} option, will be marked by being printed in bold or bright
(depending on the terminal.) This options differs from @option{-l} by printing
alternative names (symbolic links) inside brackets after their target ponies.

@item +l
@itemx ++list
@opindex @option{+l}
@opindex @option{++list}
Just as @option{-l}, except it lists extra (non-MLP:FiM) ponies instead of
standard (MLP:FiM) ponies.

@item +L
@itemx ++symlist
@itemx ++altlist
@opindex @option{+L}
@opindex @option{++symlist}
@opindex @option{++altlist}
Just as @option{-L}, except it lists extra (non-MLP:FiM) ponies instead of
standard (MLP:FiM) ponies.

@item -B
@itemx --bubblelist
@itemx --balloonlist
@opindex @option{-B}
@opindex @option{--bubblelist}
@opindex @option{--balloonlist}
Prints a list of all balloon styles.

@item -A
@itemx --all
@opindex @option{-A}
@opindex @option{--all}
List all ponies, MLP:FiM and non-MLP:FiM, in this case the first list are
MLP:FiM and the second are non-MLP:FiM.

@item +A
@itemx ++all
@itemx --symall
@itemx --altall
@opindex @option{+A}
@opindex @option{++all}
@opindex @option{--symall}
@opindex @option{--altall}
List all ponies names, including alternatives, these from MLP:FiM and
non-MLP:FiM. The first list are the MLP:FiM and the second one are non-MLP:FiM.

@item -o
@itemx --pony-only
@itemx --ponyonly
@opindex @option{-o}
@opindex @option{--pony-only}
@opindex @option{--ponyonly}
Print just the pony, nothing else like the speech balloon. Naturally the
@command{ponysay} will not wait for a message from stdin.

@item -i
@itemx --info
@opindex @option{-i}
@opindex @option{--info}
By adding this flag you will get a metadata for a pony printed, rather than
the pony itself. The output will beformated with bold tag names. The output
will be wrapped according to the @option{-W} option.

@item +i
@itemx ++info
@opindex @option{+i}
@opindex @option{++info}
This works just like the @option{-i} option, except the pony will use the output
has her message rather that just print that information.

@item -r RESTRICTION
@itemx --restrict RESTRICTION
@opindex @option{-r}
@opindex @option{--restrict}
This option is used to restrict which ponies can be randomly select based one
their metadata. The restrict is given is disjunctive normal form, and can
hence express any logical combination, however only for tags with one entry.
For tags with multiple values all values are tested and of one of them passes
a test passes.

The argument for @option{--restrict} is a @code{+} separated list of values
that all must be satisfied for a pony to be qualified for random selection.
The option @option{--restrict} can be used multiply times, only one of them
need to be satisfied for a pony to qualified for random selection.

A value in the argument is a combination of the tag name and tag value on
the form @code{NAME=VALUE}. Additionally if the tag names ends with a question
mark (@code{?}) the tag is satsified if the tag is missing; if the value starts
with a bang (@code{!}) the test is inverted. Using just a bang means that the
test passes for and only for all ponies with the tag definied; using the
question mark and a empty value means that the test passes for all ponies;
finally, using the question mark and just a bang for the value means that the
test passes for and only for all ponies without the tag definied.

For most shells, if not all, trick to not need to use disjunctive normal form
is to use @code{@{ @}}. For example if you use
@option{--restrict=@{eye=@{blue,green,cyan@}+coat=@{black,grey@},coat=white@}}
(note that there is no whitespaces) means that only ponies with white coat
will be randomly selected as will as ponies with black or grey coat provided
that they have either blue, green or cyan eyes.

@item -X
@itemx --256-colours
@itemx --256colours
@itemx --x-colours
@opindex @option{-X}
@opindex @option{--256-colours}
@opindex @option{--256colours}
@opindex @option{--x-colours}
Use @command{xterm}'s 256-colour support (supported by most X11 terminals),
despite your terminal's actual compatibilies. 

@item -V
@itemx --tty-colours
@itemx --ttycolours
@itemx --vt-colours
@opindex @option{-V}
@opindex @option{--tty-colours}
@opindex @option{--ttycolours}
@opindex @option{--vt-colours}
Use Linux VT's compatbilies without KMS utilisation, despite your terminal's
actual compatibilies.

@item -K
@itemx --kms-colours
@itemx --kmscolours
@opindex @option{-K}
@opindex @option{--kms-colours}
@opindex @option{--kmscolours}
Use Linux VT's compatbilies with KMS utilisation, despite your terminal's actual
compatibilies.

@item +c
@itemx --colour ANSI-COLOUR
@opindex @option{+c}
@opindex @option{--colour}
Colour the balloon, including link and message (the parts that are not
individually specified.) The argument, should be a ANSI colour sequence without
leading CSI and without a tailing ‘m’, for example @code{1;31} will make it in
red and bold (or bright depending on the terminal.)

@item --colour-bubble
@itemx --colour-balloon ANSI-COLOUR
@opindex @option{--colour-bubble}
@opindex @option{--colour-balloon}
Just like @option{--colour}, but it only colours the balloon, without the
message or link.

@item --colour-link ANSI-COLOUR
@opindex @option{--colour-link}
Just like @option{--colour}, but it only colours the balloon link.

@item --colour-msg
@itemx --colour-message ANSI-COLOUR
@opindex @option{--colour-msg}
@opindex @option{--colour-message}
Just like @option{--colour}, but it only colours the message.

@item --colour-pony ANSI-COLOUR
@opindex @option{--colour-pony}
Just like @option{--colour}, but it colours the pony. This colouring has no
effect ony regular pony files, as it has its own colouring.

@item --colour-wrap
@itemx --colour-hyphen ANSI-COLOUR
@opindex @option{--colour-wrap}
@opindex @option{--colour-hyphen}
Just like @option{--colour}, but it colours hyphen added by the word wrapping.
By default this is red (@code{31}), if you want uncoloured use @code{0},
without @code{0} or @code{39}, the default @code{31} is presistent.

@end table

@opindex @var{message}
If neither @option{-q} is used nor any @var{message} is specified,
@command{ponysay} will read the message from stdin (standard input); however,
if no arguments are used and nothing is piped to stdin, a help message will be
printed. If you want to use @command{ponysay} without arguments and enter the
message by hand, you can run @code{cat | ponysay}.

@cindex @file{best.pony}
If no pony is selected, @command{ponysay} will look for a @file{best.pony} file,
this file should be a symbolic link to the pony you want as a default.
If it is not a symbolic link, @option{-q} cannot determine which quotes to use.

@node Extra information
@section Extra information
@cindex file descriptor 3
@cindex extra information
@cindex verbose mode
@pindex @command{tee}
If file descriptor 3 is definied when @command{ponysay} is executed, extra
information is printed to it. The printed information includes the name of the
pony file, the name of the balloon style file, and if definied in the pony
file, file meta data and comment.

In most shells, a file descriptor 3 can defined using @command{3> FILE}, and
linked to stderr using @command{3>&2}. For example, you can print the
information to @file{~/info} by running @command{ponysay I\'m just the cutest
pony! 3> ~/info}.

The message is not stored this way, for that you can use @command{tee}.
However, if you use @option{-q} the quote file is printed to file descriptor 3.


@node Fortune cookies
@section Fortune cookies
@pindex @command{fortune}
@cindex startup
@cindex on startup
@cindex @file{.bashrc}
@cindex @file{~/.bashrc}

If you have @command{fortune} installed -- this program may be named
@command{fortune-mod} in your GNU/Linux distributions package repository --
you can run @code{fortune | ponysay} to get a random pony reading a random
fortune cookie.

By adding @code{fortune | ponysay} to the end [easiest way] of your
@file{~/.bashrc} -- or equivalent for your shell if you do not use GNU Bash
(standard shell for most distributions now a days) -- you will get the effect
described in the previous paragraph every time you open a terminal.


@node Ponification
@section Ponification
@cindex ponification
@cindex text ponification
@pindex @command{ponypipe}

You can ponify messages (i.e. replaces words search as `everyone' with
`everypony') by using @code{fortune | ponypipe} instead of using
@command{fortune}. @command{ponypipe} can be downloaded from
@url{https://github.com/maandree/ponypipe}. Alternatively you can use
@command{pinkie} (or @command{pinkiepie}), which can be downloaded from
@url{https://github.com/maandree/pinkie-pie}, which is just
@code{fortune | ponypipe}. There is also a large @command{sed} script, similar
to @command{ponypipe}: @url{http://www.reddit.com/r/mylittlelinux/comments/srixi/using_ponysay_with_a_ponified_fortune_warning/}
However I think @command{ponypipe} as better at replacing words than the
@command{sed} script, but I haven't used the script so I wouldn't know for sure.


@node Running on TTY
@section Running on TTY
@cindex TTY
@pindex Linux VT
@cindex @file{.bashrc}
@cindex @file{~/.bashrc}

If you use TTY and have a custom colour palette, you should also add to your
@file{~/.bashrc}, before @code{fortune | ponysay}:
@cartouche
@example
[ "$TERM" = "linux" ] &&
    function ponysay
    @{   /usr/bin/ponysay "$@@"
        #RESET PALETTE HERE
    @}

@cindex @file{~/.bashrc}

@command{screen} and @command{tmux} will adapt ANSI colour escape sequences
to your terminal's capabilities. This means that if your terminal reports
itself as @code{xterm} in @env{$TERM} ponies will lose their colours; they
will only use the lower 16 colours instead of the top 240 colours. By default,
almost all X terminals, including @command{xterm} and @command{mate-terminal}
reports themselves as @code{xterm} in @env{$TERM}, and some reports their
actual name in @env{$COLORTERM}. So before opening @command{screen} or
@command{tmux} you should set @env{$TERM} to @code{xterm-256color}, if you
are using a terminal with support for @code{xterm}'s 256 colours; this can
be done by adding to your @file{~/.bashrc}:
@cartouche
@example
[ "$TERM" = "xterm" ] &&
    function screen
    @{  TERM=xterm-256color /usr/bin/screen "$@@"
    @}


[ "$TERM" = "xterm" ] &&
    function tmux
    @{  TERM=xterm-256color /usr/bin/tmux "$@@"
    @}
@end example
@end cartouche

Alternatively, you can run @command{tmux} with the option @option{-2}:
@command{tmux -2}. This also forces @command{tmux} to assume the terminal
supports 256 colours.


@node ~/.ponysayrc
@section @file{~/.ponysayrc}
@cindex @file{~/.ponysayrc}
@cindex environment variables

If you have the file @file{~/.ponysayrc} (@file{.ponysayrc} in your home
directory, the home directory can be spoofed by changing the system
environment @env{HOME},) the first thing @command{ponysay} does is running that
file. This can be used for modifing environment variables
(see @ref{Environment variables}). For your convience this can be done by
modifing the map @code{env}. The code in @file{~/.ponysayrc} must be written
in Python 3.

For example if you want to set the @env{PONYSAY_SHELL_LINES} to 5, but only 1 if
you are using Linux VT (TTY), your @file{~/.ponysayrc} may look like this:
@cartouche
@example
if env[TERM] == 'linux':
    env[PONYSAY_SHELL_LINES] = 1
else:
    env[PONYSAY_SHELL_LINES] = 5
@end example
@end cartouche

You can examine the source code of @command{ponysay} to figure out some nice
hacking you may want to do, everything in the source code can be used directly
as long as it is defined before @file{~/.ponysayrc} is interpreted.

@file{~/.ponysayrc} is a fallback for @file{~/.config/ponysay/ponysayrc},
which in turn is a fallback for @file{$@{XDG_CONFIG_HOME@}/ponysay/ponysayrc}.
If neither of those exist, @file{/etc/ponysayrc} is used if that exists.

@section Narcissistic ponies
@cindex narcissistic ponies

The following will not work if you have line breaks in you file names, but if
you do have that, you may want to rethink that as it will usually cause
problems for programs, especially for shell scripts.

The command @command{__pony=$(ponysay -o 3>&1 1>/dev/null | grep ^pony\ file: |
sed -e s/^pony\ file:\ //g) && (ponysay -of "$__pony" | ponythink -Wn -f "$__pony")}
will give you a pony thinking of herself. The command works on GNU Bash, but may
not work on less POSIX compatible shells. It works by first getting a random
pony and then uses the extra information printed to the file descriptor 3 (see
@ref{Extra information}) to fetch the file name with help of @command{grep} and
@command{sed}. The file name is stored in a shell variable. It then the pipes
output from one execution of ponysay into the second, using the stored file
name in both. This does not work on FISH shell because of POSIX incompatibility.

Ponysay can use just about anything as a message because it quarantines the
message's ANSI escape sequences, including colour. And is Unicode aware
(including combining characters) and ANSI escape sequence aware.

Naturally this means that you can also make ponies think of eachother,
for example: @command{ponysay -f rarity -b round 'My little Spiky-wiky' |
ponythink -f spikefloat -b unicode -W n}



@node Environment variables
@chapter Environment variables
@cindex environment variables
@cindex truncation

@command{ponysay} supports the follow environment variables:

@table @env
@item PONYSAY_BOTTOM
@vindex @env{PONYSAY_BOTTOM}
@cindex TTY
@cindex Linux VT
Under TTY (Linux VT), if the output is larger the the screen's height, only
the beginning is printed, leaving two blank lines. If you want the bottom
to be printed rather the the beginning you can export @env{PONYSAY_BOTTOM}
with the value @code{yes}, @code{y} or @code{1}.

@item PONYSAY_SHELL_LINES
@vindex @env{PONYSAY_SHELL_LINES}
@cindex TTY
@cindex Linux VT
Under TTY (Linux VT), if the output is larger than the screen's height, two
lines are left blank. If you want more, or less, blank lines you can export
@env{PONYSAY_SHELL_LINES} with the value of how many blank lines you want.
Naturally this takes effect eve n if the output is not actually larger than
the screen.

@item PONYSAY_FULL_WIDTH
@vindex @env{PONYSAY_FULL_WIDTH}
You can export @env{PONYSAY_FULL_WIDTH} with the value @code{yes}, @code{y}
or @code{1}, if you do not want the output to be truncated on the width to
fit the terminal.

@item PONYSAY_TRUNCATE_HEIGHT
@vindex @env{PONYSAY_TRUNCATE_HEIGHT}
Export @env{PONYSAY_TRUNCATE_HEIGHT} with the value @code{yes}, @code{y}
or @code{1}, if you want to truncate the output on the height even if you
are not running @command{ponysay} under TTY.

@item PONYSAY_UCS_ME
@vindex @env{PONYSAY_UCS_ME}
@cindex UCS
@cindex Universal Character Set
@cindex Unicode
@cindex ASCII
Export @env{PONYSAY_UCS_ME} with the value @code{yes}, @code{y} or @code{1},
if you want [simulated] symlink to pony files using Universal Character Set
in their names. Otherwise pony files uses only ASCII. If you want to remove
the ASCII:ised names export @env{PONYSAY_UCS_ME} with the value @code{harder},
@code{h} or @code{2} instead.

If you have not enabled this, UCS names are not usable, suggested or listed.
If you use @code{yes} UCS names will be usable, suggested and listed. If you
use @code{harder} ASCII:ised names will not be suggested or listed, but they
will still be usable.

@cindex kernel mode setting

@env{PONYSAY_KMS_PALETTE} or @env{PONYSAY_KMS_PALETTE_CMD} is used to tell
ponysay how your TTY palette looks, this feature lets you get the best images
in TTY if you have Kernel Mode Setting (KMS) support.

See @ref{KMS ponies} for information on how to use this.

@item @env{PONYSAY_TYPO_LIMIT}
@vindex @env{PONYSAY_TYPO_LIMIT}
@cindex auto correction
@cindex typo correction
@cindex spello correction

ponysay is able to auto correct misspelled pony names and balloon style name.
Without consideration for transpositioning, the distance between two words are
measured in the number of edits needed to get from one word to the other, with
weighting on some character changes used to favour spellos over typos.

By default if the weighted distance is greater than 5 for the closest words,
auto correction ignored. This limit can be changed by exporting the limit to
@env{PONYSAY_TYPO_LIMIT}; setting the limit to zero will disable auto
correction.

@item @env{PONYSAY_WRAP_HYPHEN}
@vindex @env{PONYSAY_WRAP_HYPHEN}
@cindex wrapping

You can export what ponysay should use instead of a hyphen when wrapping
messages. The hythen is red by default, if you want to change the colour or
other formating, should should do so using the option
@option{--colour-hyphen} (@option{--colour-wrap}).

@item @env{PONYSAY_WRAP_LIMIT}
@vindex @env{PONYSAY_WRAP_LIMIT}
@cindex wrapping

Defines how long a word mush be to be hyphenated. This is used for to wrap words
that are long so the output gets as pretty as possible. This s not the only
condition under which a word can be hyphenated, it can also be hyphenated if
the word cannot fit otherwise. The default value is 8.

@item @env{PONYSAY_WRAP_EXCEED}
@vindex @env{PONYSAY_WRAP_EXCEED}
@cindex wrapping

Defines how much a word must exceed the wrapping point to be hyphenated.
This setting is used togather with @env{PONYSAY_WRAP_LIMIT}.
The default value is 5.

KMS ponies is an optional feature that required that you have
@command{util-say>=3} (@command{util-say<2} for @command{ponysay<2.1} and
@command{util-say<3} for @command{ponysay<3}) installed. It lets TTY users that
have a custom TTY colour palette and KMS support get best TTY images that can be
display at the current state of the art. KMS is supported on most computers, but
due to lack of published specifications Nvidia drivers does not support KMS.
Other video cards can have problems too like `gma500_gfx' due to lack of propper
drivers and correct KMS support.
@command{util-say} can be downloaded at
@url{https://github.com/maandree/util-say}.

To use this feature your @file{~/.bashrc} (or equivalent for your shell) must
keep track of your colour palette; it is not possible for a program to ask to
terminal. Either the shell should export a palette string to @env{$PONYSAY_KMS_PALETTE}
or you should export a command to can get the palette string to
@env{$PONYSAY_KMS_PALETTE_CMD}. The palette string should be the stream which
sets the colour palette to the terminal when @command{echo}:ed; preferably,
to increase speed and reduce cache usage, it should be consistent every time
it is exported for every colours palette. So you may want to keep it sorted,
always be in either upper case or lower case, and not contain an character
that is not used to set the colour palette.

Assuming you have a function in your @file{~/.bashrc}, to reset the colour
palette to what you set it to last time in the terminal, named
@command{reset-palette}, your @file{~/.bashrc} should, for example, contain:
@cartouche
@example
[ "$TERM" = "linux" ] &&
    function ponysay
    @{   export PONYSAY_KMS_PALETTE="$(reset-palette)"
        exec ponysay "$@@"
    @}
@end example
@end cartouche

KMS ponies uses @file{/var/cache/ponysay/} or, if missing,
@file{~/.cache/ponysay/} for cache space.

@node Pony metadata
@chapter Pony metadata
@cindex pony metadata
@cindex metadata
@cindex tags, metadata
@cindex comments, metadata
@cindex pony tags, metadata
@cindex pony comments, metadata

Pony files can contain metadata tags and a multiline comment.
The following are the standard tags (comma separated lists may
have whitespace surrounding the comma [@code{,}]):

@table @var
@item GROUP NAME
@vindex @var{GROUP NAME}
If a pony file contains multiple ponies, it @emph{should} have a
@var{GROUP NAME} tag. The tag is a comma seperated list of the recognised
names of the ponies as a groups, if the list is empty the tag value must be
@code{(none)}. An officiallity tag should be added to each name.

@item NAME
@vindex @var{NAME}
Every pony file should have this tag, one entry for each pony on the file.
The value of the tag @emph{must} be the pony's most common name as used on
the TV show (or other source). If the pony's name have not been mentioned
the value must be @code{(not mentioned)}.

@item OTHER NAMES
@vindex @var{OTHER NAMES}
If a pony in the pony file has other names then the one in @var{NAME} it
@emph{should} have this take for this pony. Any pony in the file (in case of
multiple ponies) that do not need this tag should use the value @code{(none)}.

The tag is a comma seperated list of alternative (to @var{NAME} names for the
pony, each name should have an officiallity tag.

@item APPEARANCE
@vindex @var{APPEARANCE}
This tag specifies in which episode the pony first appeared. It reasonable to
specify it even for ponies that appears in every episode.

For uniformity the format @code{S%sE%e %t [%P]} is recommended; @code{[ ]}
denotes and optional part, optional in the sence that it does not apply the
every episode, but it @emph{should} be used if applicable. @code{%s} is the
series (season) number in two digits, @code{%e} is the episode number in two
digits. @code{%t} is the episode title and should use the standardised title
format for the used format however without surrounding quotes if the used
language has that, in the unlike event that @code{[} or @code{]} is present in
the title it should be backslashed (@code{\[}, @code{\]}). @code{%P} is the
part in the format @code{[Part %p]}, where @code{[ ]} @i{does not} denote and
optional part but rather is verbatim, and @code{%p} is the part number in one
digit (well, if the part number is not 10 or higher).

The standard way to format titles in American English is the same as in British
English, however it is not fully standardised. Capitalisation of the first word,
and all other words, except for articles, prepositions, conjunctions, and forms
of `to be' is recommended.

Be aware that MLP:FiM episodes use American spelling which include a rather
uncommon way to write for examples abbrevations (like for example Mr. instead
of Mr), this may however not be the case for non-MLP:FiM episodes. And if there
are not series (season) the series number defaults to 1, however other numbers
and tags (which the part number is) may be added if required.

@item KIND
@vindex @var{KIND}
This tag decribes what kind of pony a pony is, it is a comma seperated lower
case list, and it cannot be empty, by it can be (but shouldn't) skipped for
every pony in the image.

Every fitting value should be used, however an alicorn (also known as alacorn,
winged unicorn, acorn, pegasus unicorn, unipeg, unisus, horned pegasus,
wing-horn, allacorn, cerapter pterippus, aquillacorn, pegasos aithiopikos,
alate unicorns, or pegacorn (really all those name has been used throw history
to define a unicorn with wing or pegasus with a horn)) should have the values
@code{alicorn} and @code{pony}, but neither @code{pegasus} nor @code{unicorn}
or another of the possible therms mentioned. Earth ponies should have the value 
@code{pony} and @code{earth} not @code{earth pony}.

The standard values are (you may use other ones if fitting):
@itemize @bullet
@item @code{unicorn}
For unicorn like @file{rarity} or presummed unicorns.
@item @code{pegasus}
For pegasi like @file{fluttershy}.
@item @code{alicorn}
For Alicorn, Winged pegasus, Pegacorn, etc. like @file{celestia}.
@item @code{earth}
For earth ponies like @file{applejack}.
@item @code{pony}
As a generic in case of unknow or sujetable like @file{headlesshorse}.
@item @code{changeling}
Changeling like @file{queenchrysalis} or @file{thorax}.
@item @code{crystal}
Any cristal pony like @file{twilightcrystal} or animal in they crystal 
form like @file{spikecrystal}.
@item @code{seapony}
Any seapony or by extenssion an orcapony from either novel, movies, comics, 
the series or the fandom like @file{sealyra}.
@item @code{breezie}
Breezies showed on the series or movies, this kind is based on the G3 
breezies, but with they unique traits like speak in a nordic accent; 
examples are @file{seabreeze} or @file{twilightbreezie} from main ponydir.
@item @code{animal}
Applies to Spike and any other animal.
@item @code{item}
Applies to @file{tom} and Pinkamina's imaginary friends.
@item @code{batpony} 
Applies to @file{royalnightguard} and others bat winged pony a like 
creatures, @emph{Word of good} say these ponies are a different species 
but merchandice call them @code{pegasus}, so you need use 
@code{pegasus} and @code{batpony} comma separated one each other for 
uniformity.
For other side @file{flutterbat} is just @file{flutershy} plus a fuit 
bat but not a natural @code{batpony} so this tag shall not be with she.
@end itemize

@item GROUP
@vindex @var{GROUP}

This tag decribes which groups a pony classifies under, it is a comma
seperated lower case list, and it cannot be empty, by it can be (but shouldn't)
skipped for every pony in the image.

The standard values are (you may use other ones if fitting):
@itemize @bullet
@item @code{mare}
Adult female pony.
@item @code{stallion}
Adult male pony.
@item @code{filly}
Female pony child.
@item @code{colt}

The mane characters (also known as main characters [unponified] or protagonists).
@item @code{wildlife}
Wildlife, for example timberwolfs.
@item @code{pet}
A pony's pet, Spike does not count because Twilight does not play with him
during pony–pet play dates.
@item @code{royal}
Royal pony, either by birth, marriage, or conquer (i.e. the old school style).
Shining Armour is royal by marriage, but his biological family doesn't become
royal by this, and Twilight Sparkle is because Princess Celestia give that 
tittle because she fullfilled they destiny.
@item @code{griffon}
Aplies to griffon (also called griffin) like Gilda and others.
@item @code{villain}
Villains, normally minions to antagonists or recurring bad ponies. 
Applies to changelings.
@item @code{antagonist}
(applies to: Nightmare Moon, Gilda, Discord, Chrysalis, Sombra, Tirek)
Antagonists are also known as archivillians or archenemies.
Nightmare Moon, Discord and Chrysalis are such, but Gilda also counts as one
for her debut.
@item @code{reconciled} (applies to Trixie, Discord, et al.)
Any @code{villain} that change to the good side (aka become a

Spike)
Important characters (excluding Derpy) that are neither protagonists,
deuteragonists nor antagonists.
@item @code{background}
Background characters are not characters that are neither protagonists,
deuteragonist, tritagonist, antagonist nor pets. They do not need to be
strictly background characters, for example Big Mac and Cheerilee classifies
under this group, as they are not too important to be considered tritagonists
(as of seasson 3).
@item @code{voiced} (only used together with background)
Only @code{background} characters can be @code{voiced}. The additional
requirement is that they have said something (ponies comics can also be voiced,
in this case they need a minimal of one big dialoge text).
@item @code{imaginary}
Imaginary ponies (or other animal), in this group classify Tom and Pinkamina's
imaginary friends for example.
@end itemize

@item BALLOON
@vindex @var{BALLOON}
For each balloon in the file (a pony file can have more than one balloon, but
that is not common) their should one tag entry. There are four values that
can be used:
@itemize @bullet
@item @code{top}
The common setup, the balloon is at the top of the image
@item @code{bottom}
The balloon is at the bottom of the image 
@item @code{right}
The balloon is neither at the top or at the bottom of the image, but is
placed to the right of the pony
@item @code{inside}
The balloon is somewhere as inside the image
@end itemize

@item LINK ON
@vindex @var{LINK ON}
Files with only one pony @emph{should not} use this tag. Specifies to which pony
the link is connected, it is a number, starting from 1.

If a file contains Fluttershy and Pinkie (in that order, i.e. Pinkie is to the
right of or below Fluttershy) and the link is connected to Pinkie, than the
value should be 2.

In the rare case that the file contains multiple links (and multi ponies), the
metadata should contains multiple entries of this tag, one entry for each link
sorted in the order of the linkes placement in the image, in the same way
ponies are ordered.

@item LINK
@vindex @var{LINK}
In the rare case that the file contains multiple links the metadata should
contains multiple entries of this tag, one entry for each link sorted in the
order of the linkes placement in the image, in the same way ponies are ordered.

The value for this tag must be either @code{regular} or @code{mirrored}.
@code{regular} applies to linkes with NNE–SSW (@code{\}) direction.
@code{mirrored} applies to linkes with NNW–SSE (@code{/}) direction,
in version 3.0.1 only @file{rainbowdrag} uses this.

@item COAT
@vindex @var{COAT}
The name of the colour (as best estimated by you), in lowercase, that the
pony's coat have. If the creature is (for example) a dragon, the colour of the
scales is used. Common colour names are preferable. Only one colour should be
named, but the name may describe a colour combination.

@item MANE
@vindex @var{MANE}
The name of the colour (as best estimated by you), in lowercase, that the
pony's mane have. Common colour names are preferable. Only one colour should
be named, but the name may describe a colour combination like @code{rainbow}
for Rainbow Dash mane colour schema or @code{pastel} for Princess Celestia.

@item EYE
@vindex @var{EYE}
The name of the colour (as best estimated by you), in lowercase, that the
pony's eyes have. Common colour names are preferable. Only one colour should
be named, but the name may describe a colour combination. If the eyes are
closed in the picture, use @code{close} in addition the the actual eye colour,
separated by a comma.

@item AURA
@vindex @var{AURA}
The name of the colour (as best estimated by you), in lowercase, that the
pony's magic aura have. Common colour names are preferable. Only one colour
should be named, but the name may describe a colour combination.

The magic aura is the colourisation around items that are affected by magic.

If the pony file have multiple ponies, some with magicial abilities and some
without, the ponies without magicial abilies should use the value
@code{(no magic)}. If the pony has magicial abilies but without an aura, use
the value @code{(invisible)}.

Only humans [here we must call ourself humans rather than ponies, otherwise
the next sentance does not make sense] can see the magic aura, describe the 
colour that we humans see, not ponies and other creatures in the TV Show 
[proof, see S01E11 Winter Wrap Up and S02E25-26 A Canterlot Wedding] 
(Presumably Discord can see Magic too).

@item DISPLAY
@vindex @var{DISPLAY}
This tag describes how a pony is places in the image. The standard values are:
@itemize @bullet
@item @code{full}
Full body)
@item @code{head}
Just the head
@item @code{down}
Upside down
@item @code{left}
Pony is looking to our left
@item @code{right}
Pony is looking to our right
@item @code{front}
Pony is looking at us. 
@code{front} Can be combined with @code{left} and @code{right},
but @code{left} and @code{right} nor @code{full} and @code{head} cannot be
combined.
@end itemize

@item WIDTH
@vindex @var{WIDTH}
The width of the pony image measured in text columns.

@item HEIGHT
@vindex @var{HEIGHT}
The height of the pony image measured in text lines, this include the balloon
(occupies one line) even if it the first line with nothing else on that line.

@item BALLOON TOP
@vindex @var{BALLOON TOP}
The number of lines at the beginning of the pony image that should be skipped
if the balloon is not printed.

@item BALLOON BOTTOM
@vindex @var{BALLOON BOTTOM}
The number of lines at the end of the pony image that should be skipped if the
balloon is not printed.

@item POSE
@vindex @var{POSE}
@cindex master file
@cindex slave file
@cindex extras
One word (preferably) to distinguish the pony files from other pony files with
the same @var{MASTER}. It is preferable that this is written in bare infinitive.
Master files should try to specify this tag but are not required
to, however, non-master files (slave files) are required to specify this tag.
@b{This tag is important for the extras feature to function.}

@item BASED ON
@vindex @var{BASED ON}
Either the name of a pony that the pony is based. If the original pony is not
from MLP:FiM, the name a value that pony's MEDIA tag can used inside brackets,
for example @code{(Tumblr)}, after the original pony's name. If the pony is not
based on any pony the value @code{(original)} can be used. If the ponies is
based on multiple ponies, make a comma separated list.

@item MASTER
@vindex @var{MASTER}
@cindex ponyquotes
@cindex quotes
This tag refers to the pony file that is not named with extra attributes.
For example, all files where Shining Armor is the (sole) speaking pony the this
tag should be @code{shiningarmor}, except for in @file{shiningarmor.pony} where
this tag may be omitted. 
@b{This tag is important for the ponyquotes feature to work.}

@item WING
@vindex @var{WING}
This is added manually only if needed, is the colour of wings from a pegasus or
other alated creature (i.e.: Chrysalis).

@item SOURCE
@vindex @var{SOURCE}
This tag specifies from where the pony image (not the file itself) originates.
If the source is unknown the value should be @code{(unknown)}, if a GitHub user
draw it the the value should be that user inside square brackets (in case of
multiple artists, the tag is comma seperated list). Otherwise the source
should be specified in any reasonable manner.

In order the claim authorship (the GitHub user value) it image must have been
written from scratch (using templates is okay) or must be a major edit of
another image. Just converting (including fixing the colours) an image (for
example from the Internet or a screenshot) with or without removing the
background is not enough.

@item MEDIA
@vindex @var{MEDIA}
This tag @emph{must not} be used for MLP:FiM ponies, but only for extraponies.
It specifies the media from where the pony (not the image) originates.

@item LICENSE
@vindex @var{LICENSE}
Which licence applies to the image? Full name and version should be used.
In case of multiple license there should be one entry for each license.
Omit this tag is the license is "not known".

The are two special cases here where this is no license. In which case it
either uses regular copyright, in which case use the value @code{(regular)},
or everyone is the copyright holder (for example Public Domain), in which
case use the value @code{(public)}.

@item FREE
@vindex @var{FREE}
Is the image fully free? (For example Linux-libre is fully free, but not
regular Linux.) 
The value @emph{must} either be @code{yes}. @code{sharable} or @code{no},
or the tag must be omitted.
@itemize @bullet
@item @code{yes} mean free like Linux-libre
@item @code{no} mean non free for @code{libre} distro
@item @code{sharable} mean that you need permission from the author of the original
image (or consept art like @file{aurora}) for inclusion with free ponies.
@end itemize

@b{This is the most important tag} as it helps us build a fully free version
that can be officially distributed on FSF endorsed GNU/Linux distributions
(GNU/Linux-libre) without problems.
@end table

Duplicate tags should be ordered in the order of the pony they describe from
top-left to bottom-right in the image. It is important that if there are for
example three ponies the image then all used tags that depends on the number
of ponies in the image is used three times.

@cindex officiallity tag
`Officiallity tag' refers the an annotation added to a tag value's list element.
If the value is unofficial the string @code{(unofficial)} is appended
(preferable with leading whitespace) to the element. If it is official the
appended string is of the format @code{(official, %c)} (the brackets are
verbatim), where @code{%c} is a comment. For example Chrysalis' name has not
been mentioned in the show, however it is used in the manuscript and comics, 
therefore a pony file with Chrysalis should have the (partial) metadata:

@example
NAME: (not mentioned)
OTHER NAMES: Chrysalis (official, in manuscript and comic)

Before reading this section you may want to read the earlier section
@ref{KMS ponies}.

@opindex @option{--kms}
Invoking the command @command{ponysay-tool --kms} (no additional options are
available) will pre-generate all kmsponies for your current TTY palette.
This is useful if your computer is not fast enough, for you, at converting a
pony to a kmspony. As the kmsponies may change between versions (noted in the
change log if it happens) you may want to run this commmend after installing a
new version of @command{ponysay}. Ponies that are already in the cache with
the current KMS version will not be re-generated.
May not work in all KMS drivers due to KMS inconsistences.

commands does not support additional options.

@cindex erase metadata
@cindex remove metadata
@opindex @option{--edit-rm}
@command{ponysay-tool --edit-rm PONY-FILE} will remove all metadata from the
file @code{PONY-FILE}. To just remove some data you must use
@command{ponysay-tool --edit PONY-FILE} or do it by hand.
Note that you always use pony file, not pony names.

@cindex copy metadata
@cindex store metadata
@cindex stash metadata
@opindex @option{--edit-stash}
@command{ponysay-tool --edit-stash PONY-FILE} will print all metadata from a

Cherry-picking cannot be done.

@cindex paste metadata
@cindex apply metadata
@cindex yank metadata
@opindex @option{--edit-apply}
@command{ponysay-tool --edit-apply PONY-FILE} replace all metadata in a file
with the metadata used provided in stdin.

@cindex copy metadata
To copy the metadata from one pony to another (and remove the old metadata)
you will have to pipe the stashing and the applying command:
@command{ponysay-tool --edit-stash SOURCE-PONY-FILE | ponysay-tool --edit-apply TARGET-PONY-FILE}
(yes this is the trix mentioned on the man pages)


@node Editing metadata
@section Editing metadata
@cindex editing metadata
@cindex metadata, editing

@opindex @option{--edit}
@command{ponysay-tool} allows you to edit the metadata in a pony file by running
@command{ponysay-tool --edit PONY-FILE}, where @code{PONY-FILE} is the pony
file to edit, not the pony name. No additional options are available.

@command{ponysay-tool --edit PONY-FILE} is interative and opens an editor
inspired by GNU Emacs.
The tool will give you the standard tags to fill and will automatically fill
in @var{HEIGHT} and @var{WIDTH} for you without allowing you to editing those
two tags. Additionally the editor will print the pony at the right side of the
terminal with the name of the file you are editing.

The commands the editor use is a small subset of the standard commands in
GNU Emacs. Currently the commands are only coded for xterm (just about all
terminals except Linux VT.) @kbd{C-x} means @kbd{x} with @kbd{control} held
down. @kbd{M-x} means @kbd{x} with @kbd{alt} (@kbd{meta}) held down.

@table @kbd
@item C-space
@itemx C-@@
Set mark; only if mark is set and is at the same position
as the point (cursor) the mark is deactivated.
A mark creates a text select, it cannot span between lines.

@item C-k
Cut out the rest of the line and add it to the kill ring.

@item C-w
Cut out selected text and add it to the kill ring.

@item M-w
Add the selected text to the kill ring and unset the mark.

@item C-y
Paste (yank) text from the kill ring.

@item M-y

@section Metadata collections
@cindex metadata collection files
@cindex pony metadata collections
@opindex @option{--metadata}

Pony metadata collection files are used by @command{ponysay} to by just reading
one file per directory determine all pony files metadata and determine which
ponies will pass the @option{--restrict} option when ponies are randomly
selected.

A metadata colletion file's content a list, of pony files with and their
corresponding metadata as a map from tag name to tag value set, serialised
with Python's cPickle module.

Running @command{ponysay-tool --metadata PONY-DIR} will generate the
file @file{metadata} with the serialised information. For use by the installer,
the files to include can be explicity declared appending their basename to the
command.


@node Dimension files

Pony dimension files are used by @command{ponysay} to determine the size of all
ponies and use that information to determine which ponies fit the terminal
and may be randomly selected.

Running @command{ponysay-tool --dimensions PONY-DIR} will generate three files
@file{widths}, @file{heights} and @file{onlyheights} to the directory
@file{PONY-DIR}, the contain optimised information about the widths, heigths
and heights with printed without the balloon, respectively, for each pony the
the directory. For use by the installer, the files to include can be explicity

Running @command{ponysay-tool --browse PONY-DIR}, or
@command{ponysay-tool -b PONY-DIR} will display all ponies in @file{PONY-DIR}
for you. You can limit the listed ponies by using the option
@option{--restrict}, or @option{-r}, that works the same was in with the
commands @command{ponysay} and @command{ponythink}. See @ref{Invoking ponysay}
for more infomation about the @option{--restrict} option.

In this browser you will on the right side have all pony files, in your selected
directory, listed except those that does not match your @option{--restrict}
settings.
In the rest of the free space, the pony select in the list is centered.
You can move the pony, in case it is too big, by using the arrows keys with
@kbd{control} held down, or using the @kbd{W}, @kbd{A}, @kbd{S}, @kbd{D} keys
(for QWERTY and QWERTZ layout,) or with the @kbd{<} (or @kbd{Ä}), @kbd{A},
@kbd{O}, @kbd{E} keys (for Dvorak and Svorak layout.) To recenter the pony
press @kbd{C-l} (@kbd{dl} with @kbd{control} held down.)

Browse between ponies using the arrow keys or with @kbd{C-n} and @kbd{C-p},
for next pony and previous pony, respectivily. Additionally, @kbd{Q} can be
used list quotes for pony, and @kbd{I} for metadata; press the key again to
return the pony browsing.

The tool can be exited using the key combinations @kbd{C-q} or @kbd{C-x C-c}.

@node Terminals
@section Terminals
@cindex terminals
@cindex fonts
@cindex broken ponies

@pindex xterm
@pindex putty
Ponysay works perfectly on @command{xterm}, @command{xterm} like terminals
including @command{putty}, settings may however need to be customised for
Unicode Character Set (UCS) support, but less well, depending on font, on VTE
based terminals including @command{mate-terminal}.

@cindex KMS
@cindex kernel mode setting
@cindex TTY
@pindex Linux VT
On Linux's native terminal Linux VT (TTY) it works less well, and not good at
all without Kernel Mode Setting (KMS) support.
See @url{https://github.com/erkin/ponysay/issues/1} for more information.
@command{ponysay} clears the screen before printing to TTY, this is because if
your graphics driver supports KMS, the colours will be messed by when the
ponies position moves on the screen, this is also reason why the output is
truncated on the height in TTY by default.

Most terminals have support for 256 colours, we do however only use the top 240
colours; this is because the lower 16 colours are usually, in contrast to the
top 240, customised. We assume that the top 240 colours have their standard
values. In TTY with KMS support we don't have any actual limit (except for
@math{2^{24}} + full transparency.)

@pindex xterm
@pindex urxvt
@pindex putty
@pindex rxvt
@pindex mrxvt
@pindex Eterm
@pindex aterm
@command{ponysay} works perfectly on @command{xterm}, @command{urxvt} and
@command{putty}, but @command{rxvt}, @command{mrxvt} and @command{Eterm} do
not have UTF-8 support and are currently not supported. Additionally
@command{aterm} have neither UTF-8 support nor 256 colour support, and is
therefore not yet supported.

@pindex 9term
Due to extreme limitations in @command{9term} @command{ponysay} will never be
able to run on it.

@pindex vt50
Any Terminal runing in VT-50 compatibility mode lost many of the VT100 
terminals capabilities like UTF-8 and 256 colour support, making
impossible for @command{ponysay} run in that emulated mode indiferent if the
terminal used can support those two requisites.

@node GNU Hurd
@section GNU Hurd
@cindex Hurd
@cindex GNU Hurd
@cindex TTY

@command{ponysay} should work just fine on GNU/Hurd, except for in the native
virtual terminal (TTY). Hurd's terminal is limited to 16 colours and does not
provide the capaility of modifing.

If we are lucky it may be possible draw pictures, in full resultions, as you
can in linux; which is currently not inplemented in @command{ponysay}.
Another, not yet implemented possiblity, is to use low resolution with ACSII
character for colour interpolation.


@node Cowsay
@section Cowsay
@pindex @command{cowsay}

This section describes the limitation of @command{cowsay}, but since version 2.1
@command{cowsay} is no longer used because of it. So none of the following
limitations are present anymore.

When @command{cowsay} determines the length of a word it measures in number of
bytes (in UTF-8), therefore non-ASCII words will malformat the balloon with
the message.

Further, @command{cowsay} does not recognise ANSI escape sequences, therefore,
using colours and text styling in messages will also malformat the balloon
with the message.

@command{cowsay} does not support balloon, including the link between the
message and the pony, customisation, other than using @command{cowthink}.
However you can modify @command{cowsay} (written Perl, so you can edit the
installed files) to make the balloon look different, maybe using box drawing
characters.

@command{cowsay} does not support setting the minimum size of the balloon, both
directions on the balloon–pony links. or any other placement of the balloon
than at the top to the left.

@cindex VTE-based terminals
@cindex terminals
@pindex @command{mate-terminal}
@pindex @command{gnome-terminal}
@pindex @command{terminator}
There is only one known bug that may occour that is external to ponysay,
meaning that it is a bug that can occour with ponysay, but is not actually
a bug in ponysay. This bug is common for programs that prints a lot of
colours, even with @command{cat}; it is only known to happen for VTE-based
terminals, such as @command{mate-terminal}, @command{gnome-terminal} and
@command{terminator}.

The bug, is that lines (often no more than one line) can skipped when all
lines move up one step, the next line is skipped instead, and so one; or
that an escape sequence is interpreted as pure text (this is common in GNU
Emacs, however GNU Emacs does not support programs such as @command{ponysay}.)

This bug can often be suppressed by piping the output to @command{cat}
multiple times when using a VTE-based terminal (or always if you prefer).
The use of VTE-based terminal can often be determined by checking for the
environment variable @var{COLORTERM}, to which VTE-based terminal usually
export their name (some reported another terminals name.)

If you want to do this in GNU Bash you can add this (with possible modifications
depending on what you also have done with @command{ponysay}) code sample
to your @file{~/.bashrc} file.

@cartouche
@example
[[ ! "$COLORTERM" = "" ]] &&
    function ponysay
    @{
        exec ponysay "$@@" | cat | cat | cat | cat
    @}
@end example
@end cartouche

It is important for this bug workaround that @command{cat} is unbuffered, which
is default in GNU's version of @command{cat}, but not in Unix's version.
If this does not work, test adding the option @option{-u} to @command{cat}.

Before installing @command{ponysay}, make sure your system have the packages
listed under @ref{Required runtime dependencies} and @ref{Package building
dependencies} installed.

Tarballs can be downloaded at
@url{https://github.com/erkin/ponysay/tarball/master} for bleeding edge, or
from @url{https://github.com/erkin/ponysay/tags} for releases.

If you have @command{git} you can @command{clone} the project URL
@url{https://github.com/erkin/ponysay.git}.

In the terminal, @command{cd} into the ponysay directory and execute
@command{./setup.py --freedom=partial install} or
@command{python3 ./setup.py --freedom=partial install}. This will install
@command{ponysay} into @file{/usr}, normally meaning you need to run as root,
e.g. by running @command{sudo ./setup.py --freedom=partial install}.

The @command{--freedom} option and manditory, if you only want completely free
ponies, use @command{--freedom=strict} instread of @command{--freedom=partial}.

Now you will be to use ponysay, run:
@command{ponysay "I am just the cutest pony!"},
or if have a specific pony in your mind: @command{ponysay -f pinkie "Partay!~"}.


@command{ponysay} comes with this @command{info} manual and a man page in section 6,
@command{man 6 ponysay} (or just @command{man ponysay}). The man page is also available
in Spanish, Swedish and Turkish: @command{man -L es 6 ponysay}, @command{man -L sv 6 ponysay},
@command{man -L tr 6 ponysay}. To install the localised manual, add the option @option{--with-man-es},
@option{--with-man-sv} or @option{--with-man-tr} when running @command{./setup.py}.

parts of the package is installed. This should be used (@code{--freedom=strict})
on distributions for GNU endorsed (endorsable) GNU/Linux-libre distributions.

If you do not want this, will need to explicity say so (you do also need to say
if you do want it) by using either of the values @code{sloppy}, @code{partial},
@code{false} or @code{no}.
@end table

Recognised compressions are @option{gz} which uses @option{gzip -9}, and
@option{xz} which uses @option{xz -9e}. @option{xz} is still exotic to most
programs, using it is not recommended. Distributors are strongly disencouraged
to compression for the PDF manual and should use
@option{--without-pdf-compression}.

You can run @command{./setup.py [OPTIONS] view} to make sure everything is
correct before building and installing.

@command{make uninstall}.

Well written package manages will uninstall files that the package is no longer
using, i.e. if deleted, moved or renamed. To uninstall files that are not longer
used, by the currently installed version you will need that versions
@file{Makefile}. 
To perform an uninstallation of old files run @command{make uninstall-old}.

Note: make is no longer supported, instead use @file{setup.py} a

@node Pony anatomy
@section Pony anatomy
@cindex pony anatomy
@cindex anatomy of pony files

The pony files are simple raw output data that can be printed to the terminal,
except it contains scalar variables. The pony images consists of white space,
lower half blocks [U+2584], upper half blocks [U+2580] and ANSI colour
sequences (CSI m), and, in TTY, colour value change sequences (OSI P).

Variables are recalled by putting the variable's name between two dollar signs
(@code{$var$}), and are stored by putting the variable's name followed by the
value between two dollar signs  and with a equality sign between the name and
the value (@code{$var=value$}). Variable names cannot include equality signs,
but the value can; dollar signs can be used by placing an ESC character before
the dollar sign.

There are three predefined variables: @code{$$} (empty variable name),
@code{$\$} and @code{$/$}. @code{$$} has a dollar sign (@code{$}) as its value,
while @code{$\$} and @code{$/$} contains the characters for the link to the
balloon directed in the same direction as the variable name's slash. New for
Ponysay 3.1 is @code{$X$}, which is a cross if the @code{$/$} directed balloon
link and the @code{$\$} directed balloon link.

Variables whose name begin with @code{balloon} are parsed as balloon inserts, it
can be either @code{balloon}, @code{balloonX}, @code{balloon,Y} or
@code{balloonX,Y}, whether @code{X} is the minimum width of the balloon and
@code{Y} is the minimum height of the balloon. New in Ponysay 3.0 is that the
@code{X} can also be an range of columns, it contains of two numbers, the
preferable start column, from the column that variables is placedon, the other
number is the minimum width of the balloon. The two values are separated either
by a @code{l}, a @code{r} or a @code{c}. If @code{l} is used the the balloon is
printed as normal, except that it if wrapping is enabled and the balloon whould
exceed the wrapping column, the balloon continues to fill on its left, at most
as much as the position value. If @code{r} is used, the balloon fills the it's
left first and then to its right. If @code{c} is used the balloon will try the
fill on its left and right side equally.

Prior to version 2.1 the pony files were cow files used by @command{cowsay},
they are partial Perl-scripts that assign a value to a scalar variable named
@code{$the_cow}. Cow files use a predefined scalar variable named
@code{$thoughts}, these are used to create a link between the message and the
pony. The message (and the balloon) itself was printed by @command{cowsay} and
is not defined in the cow files.


@node Pony metadata extension
@section Pony metadata extension
@cindex pony metadata
@cindex metadata
@cindex tags, metadata
@cindex comments, metadata
@cindex pony tags, metadata
@cindex pony comments, metadata

New in ponysay 3.0 is pony metadata, this feature is not supported in
@command{util-say} (at least not yet). It extends the previously
described@footnote{@ref{Pony anatomy}} format of the pony files, by letting you
specify details about the pony image, and the pony itself, as well as adding
comments.

The metadata entry must be at the absolute beginning of the file (UTF-8 signture
excluded), and is the file must be encoded in UNIX line breaks. The metadata
entry begins with a line with exactly 3 dollar signs and nothing else
(@code{$$$}), and end in the same way direct follow by the pony image starting
from the next line.

A metadata tag consists of a tag name in upper case and a tag value, with a
colon (@code{:}), optionally with surrounding regular spaces or tab spaces, but
at least one regular space or tab space directly after the colon. The name can
only consist of A to Z (upper case ASCII letters) and regular spaces. All tab
spaces in the tag names and values are handled as regular spaces. Multiple tag
names can be used multiple times or can be completely skipped. There are only a
few tags, namely @var{BALLOON TOP}, @var{BALLOON BOTTOM}, @var{MASTER} and
@var{FREE}, that absolutely should not be used muliple tag, but nor should
@var{WIDTH} and @var{HEIGHT}; a general rule is that a tag desribing a pony
should be duplicated exactly as many times as there are ponies in the image.

Any line that does not conform to the format of a tag line is a part of the
comment field. Leading line breaks in the comment field is ignored.


@node Pony quote infrastructure
@section Pony quote infrastructure
@cindex pony quote infrastructure
@cindex quote infrastructure

When compiling, pony quotes are built to @file{quotes/}, the file names are
lists of ponies joined with plus signs (@code{+}) -- the pony names are the
same as the pony files, except they do not end with @file{.pony} -- with a
index at the end, and a full stop (@code{.}) before the index.

The source files are located in @file{ponyquotes/}, where their is a file named
@file{ponies}. This file is called the pony map, and is the basis for how the
compiled files are named. In the ponymap ponies with the same quotes are on the
same line join together with plus signs (@code{+}), if the lines because too
long for file names the line is split into multiple lines with the first pony
in common.

In @file{ponyquotes/} there are also quote files, each contain just one quote,
just as when compiled to @file{quotes/}. The source quote files are identical
to the compiled quote files, except that their name contains just the first
pony.


@node Balloon style files
@section Balloon style files
@cindex balloon style files
@cindex bubble style files
@pindex ponythink

Balloon style files are located in the directory @file{balloons/}, the ones
ending with @file{.say} applies to @command{ponysay} and the ones ending with
@file{.think} applies to @command{ponythink}.

Balloon style consists of 20 strings. Each string is defined on separate lines,
by their name and their value separated with a colon (@code{name:value}), if
the name is empty it continues the last one on a new line in the value. Only 10
of the strings may be multi-lined: @var{nw}, @var{nnw}, @var{n}, @var{nne},
@var{ne}, @var{sw}, @var{ssw}, @var{s}, @var{sse} and @var{se}.

The following strings are used, and must be defined in the files:
@table @var
@item \
The character for the link to the balloon directed as @code{\}.
@item /
The character for the link to the balloon directed as @code{/}.
@item ww
The beginning of the balloon's line where the message is located if and only
if the message contains only one line.
@item ee
The end of the balloon's line where the message is located if and only if the
message contains only one line.
@item nw
The top left corner of the balloon.
@item nnw
If both this string and the @var{nne} string fits between the top corners,
this is printed directly to the right of the top left corner.
@item n
The top edge of the balloon.
@item nne
If both this string and the @var{nnw} string fits between the top corners,
this is printed directly to the right of the top left corner.
@item ne
The top right corner of the balloon.
@item nee
The end of the balloon's line where the message's first line is located if and
only if the message contains more than one line.
@item e
The right edge of the balloon.
@item see
The end of the balloon's line where the message's last line is located if and
only if the message contains more than one line.
@item se
The bottom right corner of the balloon.
@item sse
If both this string and the @var{ssw} string fits between the bottom corners,
this is printed directly to the left of the bottom right corner.
@item s
The bottom edge of the balloon.
@item ssw
If both this string and the @var{sse} string fits between the bottom corners,
this is printed directly to the right of the bottom left corner.

@cindex TTY
@pindex Linux VT
@cindex clearing TTY

@cindex kernel mode setting

Since Linux VT (TTY) does not have capabilities for returning the position of
the cursor, the screen must always be cleared before printing the ponies to
make sure the pony's colours is not lost, i.e. reduced to mare 16 colours,
during print. The colours are reduced if the pony's position on the screen is
changed. This is only relevant with KMS support. The clear the screen we print
``@code{\e[H\e[2J}'' (@code{\e} is ESC) in at beginning. ``@code{\e[H}'' places
the cursor at the beginning of the screen, and ``@code{\e[2J}'' clears
everything on the screen after, and including at, the cursor. If we would use
``@code{\ec}'' (that is a reset), we would also turn off num. lock and caps.

@node Truncation
@section Truncation
@cindex truncation
@cindex output truncation
@cindex KMS
@cindex kernel mode setting

Ponysay supports three type of output truncations, cutting away overflow on
the right and truncation the height by either keeping the bottom or keeping
the top. By default the latest is enabled under TTY, cutting away overflow on
the right is always enabled by default.

Truncating the height in TTY is required under Kernel Mode Setting (KMS) support
to keep the colours from being messed up when the ponies is moved in the screen
during print. Prior to version 2.0 this was done either by piping to
@command{head} (keeps the top) or by piping to @command{tail} (keeps the
bottom.) @command{head} and @command{tail} takes as argument the number of
lines to keep at most.

The size of the terminal, measured in characters, is fetched from
@command{stty size}, which returns @code{HEIGHT WIDTH}, and @command{cut} it
the used to get either the height or the width. This requires only
GNU Coreutils; earlier @command{tput rows} and @command{tput cols} were used,
this however required, the only de facto standard, package @command{ncurses},
some shells have environment variables for this.

Since version 2.1 truncation is done internally in the Python script, before
that it was done in a custom C program @command{truncater}, that was installed
to @file{/usr/lib/ponysay/truncater}. It recognised UTF-8 ANSI escape sequences,
including OSI P and CSI m, which is essential for the truncation to be correct.
It also expands tabs to every eighth column and resets the background colour
when needed, and writes ANSI escape sequences that are on the left side of the
truncation. The truncater stops CSI sequences on the first ASCII letter
(@code{[a-zA-Z]}), but also stops escape sequences after the first character
after the initial escape if it is not either @code{[} (CSI) or @code{]} (OSI).
In the previous, C, program it supported UTF-8 by assuming that bytes do not
match @code{10xxxxxx} and only those bytes were visible. This now fixed
internally in Python, but has also been improved to exclude combining characters
from the set of visible characters. Another difference is that the background
colours are not reset, instead ANSI colours after the truncation point are
still printed.


@node Languages
@section Languages
@cindex languages
@cindex script languages
@cindex program languages

Before version 2.0 @command{ponysay} was written primarily in GNU Bash script;
the truncater was however written in C, because it is simple, fast, does not
pose addition dependencies, and is easy to do byte hacking in.

Sometimes shell is too slow, in these cases Perl was used; Perl was already
required by @command{cowsay}, it is also similar to shell, but also supports
hash tables.

However since version 2.0 we were trying to move from all there languages and
only use Python 3, which as been accomplished in version 2.1.


@node Shell auto-completion
@section Shell auto-completion

@cindex shell, auto-completion
@opindex @option{--onelist}
@opindex @option{++onelist}
@opindex @option{--Onelist}
@opindex @option{--quoters}
@pindex @command{auto-auto-complete}

To make it easier to write auto-completion for shells, @command{ponysay}
supports the options @option{--onelist}, @option{++onelist}, @option{--Onelist}
and @option{--quoters}, which has no short versions. To make it even easier we
use @command{auto-auto-complete} (@url{https://www.github.com/maandree/auto-auto-complete})
to generate auto-completion scripts, currently it supports @command{bash},
@command{fish} and @command{zsh}, the built system uses that program to generate
completion for each shell.

Executing @command{ponysay --onelist} will list every available standard
(MLP:FiM) pony, independent of where it is located, the output is a sorted and
consists only of one pony per line.

Executing @command{ponysay ++onelist} will list every available extra
(non-MLP:FiM) pony, independent of where it is located, the output is a sorted
and consists only of one pony per line.

Executing @command{ponysay --Onelist} will list every available standard pony as
well as extra pony, independent of where it is located, the output is a sorted
and consists only of one pony per line.

@command{ponysay --quoters} work just as @command{ponysay --onelist}, excepts
it limits the ponies to those that have quotes. Ponies that have quotes,
but does not exist, i.e. does not have a .pony-file, are not listed.

Auto-completion scripts should not suggest these options.


@node Universal Character Set
@section Universal Character Set
@cindex Universal Character Set
@cindex UCS
@cindex Unicode
@cindex pony names

In earlier versions of @command{ponysay} only the output truncation supported
Universal Character Set, though handcoded UTF-8 character counting. Now
@command{ponysay} lets Python decode the data, Python store all 31 bits of a
character in as one character, not in UTF-16 as some other languages does, this
means that the code is agnostic to the character encoding. However in Unicode
6.1 their are four ranges of combining characters, these do not take up any
width in proper terminal, we therefore have a class in the code named @code{UCS}
that help us take them into consideration when determine the length of a string.

Some ponies have names that contain non-ASCII characters, read about it in
@ref{Environment variables}. The UCS names are stored in the file
@file{share/ucsmap}, in it lines that are not empty and does not start with a
hash (@code{#}) are parsed, and contains a UCS name and a ASCII:ised name.
The UCS name comes first, followed by the ASCII:ised name that the UCS name
should replace or link towards. The two names are separated by and simple left
to right arrow character [U+2192], optionally with surrounding white space.

It is important that the UCS names are stored in a file and not in file names,
because it can cause problems on some platforms.

@node Providing ponies
@section Providing ponies
@cindex create pony file

Most pony images are browser ponies or desktop ponies, browser ponies is a port
of desktop ponies, implementing it in JavaScript. Browser ponies are available
at @url{https://github.com/panzi/Browser-Ponies}. Desktop ponies are available
at @url{http://desktop-pony-team.deviantart.com/}.

There is also a collection of ponies that are not yet pixelated in a Java
reimplementation of the early Ponysay:
@url{https://github.com/maandree/unisay/tree/develop/dev/newponies}

There is a checklist named @file{pony-checklist} at the @file{dev/} directory.
You can use the check which ponies are added and which are not. Please update it
when fit.
@*

New ponies can be created from regular images by using util-say, which is
available at @url{https://github.com/maandree/util-say}.
Prior to version 2.1 of @command{ponysay}, @command{img2xterm} could be used,
by since version 2.1 @command{ponysay} is using a new format that only util-say
supports. @command{img2xterm} (@url{https://github.com/rossy2401/img2xterm})
was used in the early stage, but util-say tries to optimise the images in some
aspects: as good as possible for low capability terminals, tries to place the
pony–balloon link, displayed as good as possible when marked in the terminal
(somewhat compromised by the first aspect,) and same width on all rows.

Using util-say:
@pindex util-say
@pindex @command{img2ponysay}
@cartouche
@example
@command{img2ponysay -2 -- SOURCE_IMAGE > PONY_FILE}

@code{PONY_FILE} should end with @file{.pony} and be localed in @file{ponies/},
or @file{extraponies/} if the pony is not a MLP:FiM pony.

Omit @option{-2} if the source image does not use double pixel size.

For more information is available in util-say's info manual.
@command{img2ponysay} is a legacy command that uses the default settings of
@command{ponytool} for converting a image file to a pony file.
@end example
@end cartouche

@*
@pindex util-say
@cindex .png
@cindex PNG images
@cindex images, PNG
@cindex Portable Network Graphics
If you have util-say installed, which is required to build ponies, you can use
PNG files as argument the for @command{ponysay -f}, this requires that the file
is named @file{.png} at the end.

@cindex palette
@cindex xterm palette
@cindex pony palette
@cindex colour palette
The following @command{bash} code will print the palette the ponies
(the terminals) use:
@cartouche
@example
c=16
while ((c < 256)); do
    echo -en "\e[48;5;$@{c@}m  \e[49m"
    c=$(( $c + 1 ))
    if (( $(( c % 36 )) == 16 )); then
        echo
    fi
done; echo
@end example
@end cartouche

@*
For the palette to be correct, which is especially important when you draw
ponies, you must not redefine the colours in the range 16 to 255 (inclusive).

@cindex ttypony
When a pony is added please also add a ttypony version, i.e. the pony files
used in TTY, but if you don't please state so in the pull request so we do not
miss the create it; the simplest way to do this is to run
@command{dev/dist.sh ttyponies} after adding the ponies to @file{ponies/},
running @command{dev/dist.sh ttyponies} will build (or rebuild) all ttyponies
with a pony present in @file{ponies/}, and creates all needed symlinks.

To be able to run @command{dev/dist.sh ttyponies} you must have the packages
listed under @ref{Dependencies for pony providers}.

@cindex ponyquotes
@cindex quotes
Also when adding new ponies, please map them up in the file
@file{ponyquotes/ponies}. If the pony is a new pony without any other
alternative image just add it to a new line, without @file{.pony}, preferably
in its alphabetical position. If the file is a symlink add it to the same line
as the target pony, and if the pony has and alternative image add it the the
same line as that pony. Ponies on the same line are separated with a plus sign
(@code{+}) without any white space. When a line is too long for a file name
(this has happened to Pinkie Pie [@file{pinkie}],) it must be split into
multiple lines, these lines should have their first pony file in common.


@node Pony naming guildlines
@section Pony naming guildlines
@cindex naming ponies
@cindex pony naming

These are not rules, this are guildlines you can use when in doubt on how you
want to name your ponies. That is, these are only suggestioned based on
observion of current practice and discussions, it is probable that these
suggestions are not optimal in complex cases.

Try to follow the MLP:FiM Wikia on
@url{http://mlp.wikia.com/wiki/List_of_ponies}, if it is in conflict with an
authorised game, such as Gameloft, it is more likely that that game has make
an error, especially ignore a game on palette mismatch, and the Wikia is
probabily more agreed with fist party merchandice, fans and crew at same time.

For in the wikia the order of precedence is: 

@itemize
@item The series itself: In they first run, and uncensored
@item The crew: M. A. Larson, Sabrina "Sibsy", Lauren Faust (For the first and second
seasson only), et al. 
@item First party merchandice: Blind Bags and colectable toys [Further
duscution is taken after any renamed]
@item Second party merchandise: Any that claim to by official whitout logo and
all the fancy stuff [further discusion first]
@item Three party merchandise: Any that use the toys or characters but
only in they tags, on-line stores and soo [Only if the evidence and use are far extended that 
a further discusion for renaming or not is needed]
@item Script and others: Sometimes a name can become official if was used in the script or in
CC for the official DVD.
@item Placeholder: Any fan given name from a voted process in a open procees on
@url{http://reddit.com/r/listofponies} where anypony can vote or give sugestions fallow
they rules. These ones @emph{CAN} potentially becomed official names 
or/and influence subsecuent discutions about renaming ponies. 
@end itemize

Sometimes there are background ponies with the same palette and cutie mark, but
of different kinds (earth pony, unicorn, pegasus and so on). In these cases the
Wikia often list them as the same pony, they are given the same name. When this
happens you can name the pony that appears first in the show just the name and
append either `earth', `unicorn' or `pegasus' depending on the kind. If the pony
is a background alicorn, it is a princess and is titled as such, you can bet
your sweet flank the Wikia will have given her a royal name 
[look ´Princess Erroria' second appearence].

When there are many alternative names, but no official, use one you think is
most recognised or your personal favourite. It with short names when the names
are similar.
Symbolic links can help in this last case.

Filesystem Hierarchy Standard (FHS), e.g. installing amusement binaries in
@file{/usr/games} instead of @file{/usr/bin} or only supporting @file{/opt}
equivalent directories you should read about configurations in
@ref{Custom installations}.

Apart from this, you should configure @command{ponysay} before building it with
