If you want to use another program than @command{cowsay} (the first

@command{cowsay} found in @env{$PATH}), you can export @env{PONYSAY_COWSAY}
|

with the value of that program. In earlier versions than version 2.0: If, and
|
||||
only if, @env{PONYSAY_COWSAY} does not have any value, @command{cowsay} is
|
||||
patch with @code{use utf8;} to the beginning. The @code{use utf8;} patch is
|
||||
introduced to make it easier to customise cowsay.
|

@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 Settings (KMS) support.

|

@env{PONYSAY_COWTHINK} will be used instead of @env{PONYSAY_COWSAY} if

KMS ponies is an optional feature that required that you have @command{util-say>=2}
|
||||
(@command{util-say<2} for @command{ponysay<2.1}) 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 Nvidea drivers does not support KMS.
|
||||
@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
