<a name="index-xterm-150"></a><a name="index-putty-151"></a>Ponysay works perfectly on <samp><span class="command">xterm</span></samp>, <samp><span class="command">xterm</span></samp> like terminals including
|
|
<samp><span class="command">putty</span></samp>, settings may however need to be customised for Unicode Character Set
|
|
(UCS) support, but less well, depending on font, on VTE based terminals including
|
|
<samp><span class="command">mate-terminal</span></samp>.
|
|
|
|
<p><a name="index-kms-152"></a><a name="index-kernel-mode-setting-153"></a><a name="index-tty-154"></a><a name="index-linux-vt-155"></a>On Linux's native terminal Linux VT (TTY) it works less well, and not good at all
|
|
without Kernel Mode Setting (KMS) support. See <a href="https://github.com/erkin/ponysay/issues/1">https://github.com/erkin/ponysay/issues/1</a>
|
|
for more information. <samp><span class="command">ponysay</span></samp> 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.
|
|
|
|
<p>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 dot have any actual limit (except for 2^24 + full
|
|
transparency.)

<samp><span class="command">putty</span></samp>, but <samp><span class="command">rxvt</span></samp>, <samp><span class="command">mrxvt</span></samp> and <samp><span class="command">Eterm</span></samp> do not have
|
|
UTF-8 support and are currently not supported. Additionally <samp><span class="command">aterm</span></samp> have
|
|
neither UTF-8 support nor 256 colour support, and is therefore not yet supported.
|
|
|
|
<p><a name="index-g_t9term-163"></a>Due to extreme limitations in <samp><span class="command">9term</span></samp> <samp><span class="command">ponysay</span></samp> will never be able to
|
|
run on it.
