@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, when
you start the terminal. But if you know anypony how does like ponies [fat chance] you
can always make screen-shots of @command{ponysay -q} executions and communication that
way over e-mail.
@node Invoking ponysay
@chapter Invoking @command{ponysay}
@cindex invoking
@cindex options
@cindex arguments
@pindex 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 -v
@itemx --verion
@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
@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 -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 -q [PONY...]
@itemx --quote [PONY...]
@opindex @option{-q}
@opindex @option{--quote}
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 after @option{-q}. If one or more ponies are added after
@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 -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 40,
as with @command{cowsay}.
@item -c
@itemx --compress
@opindex @option{-c}
@opindex @option{--compress}
@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 --balloonlist
@opindex @option{-B}
@opindex @option{--bubblelist}
@opindex @option{--balloonlist}
Prints a list of all balloon styles.
@item -A
@itemx --balloonlist
@opindex @option{-A}
@opindex @option{--all}
@opindex @option{--all}
Show 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 --balloonlist
@opindex @option{+A}
@opindex @option{++all}
@opindex @option{++all}
Show both 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.
@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.

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 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
[ "$TERM" = "linux" ] &&
function ponysay
@{ exec ponysay "$@@"
#RESET PALETTE HERE
@}
@end example
@end cartouche
You should read more about this in @ref{KMS ponies}.
@node Running on screen
@section Running on @command{screen}
@pindex screen
@cindex @file{.bashrc}
@cindex @file{~/.bashrc}
@command{screen} 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{$COLORTERM}.
So before opening @command{screen} you use set @env{$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
[ "$TERM" = "xterm" ] &&
function screen
@{ export TERM="xterm-256color"
exec screen "$@@"
@}
@end example
@end cartouche
@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
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
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.

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 Nvidia 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
@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.

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 dot have any actual limit (except for @math{2^{24}} + full
transparency.)

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.
@node Cowsay
@section Cowsay
@pindex 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.

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 install} or @command{python3 setup.py 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 install}.
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!~"}.
@cindex manpage translations
@command{ponysay} comes with this @command{info} manual and a manpage in section 6,
@command{man 6 ponysay} (or just @command{man ponysay}). The manpage is also available
in Spanish: @command{man -L es 6 ponysay}. To install the Spanish manual add the
option @option{--with-man-es} when running @command{./configure}.

With the exception for with @option{--with-everything} and @option{--with-nothing},
every option that starts with @option{--with-} or @option{--without-} exists in both
variants. @option{--with-} options install parts of the package. @option{--without-}
options skips installation of parts of the packages. With the same exception,
@option{--without-} options take not arguments and @option{--with-} optionally takes
an argument, if no argument is provided a default argument is implied.
The configuration script recognised the following options, the default values for
options with arguments are written after the equality sign (@code{=}) in the option:

Recognised arguments are @code{copy}, @code{hard} and @code{symbolic}.
@code{copy} implies that files and directories are not linked, but duplicated.
@command{ponysay -L} will give the same output as @command{ponysay -l} if @code{copy}
or @code{hard} is used. This is because it does link reading and not content or
inode comparison.
@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 bost programs, use 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{./configure [OPTIONS] view} to make sure everything is correct
before building and installing.

@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.
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.
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
@var{$the_cow}. Cow files use a predefined scalar variable named @code{$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 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.
@item sw
The bottom left corner of the balloon.
@item sww
The beginning 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 w
The left edge of the balloon.
@item nww
The beginning of the balloon's line where the message's first line is located if and

@section Printing in TTY with KMS
@cindex tty
@pindex linux vt
@cindex clearing tty
@cindex kms
@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. lock.
@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.

@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.

@section Shell auto-completion

@cindex shell, auto-completion
@opindex @option{--onelist}
@opindex @option{++onelist}
@opindex @option{--quoters}
To make it easier to write auto-completion for shells, @command{ponysay} supports
the two options @option{--onelist}, @option{++onelist} and @option{--quoters},
which has no short versions.
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.
@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.

@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
@code{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 see:
@url{https://github.com/maandree/util-say/wiki/img2ponysay}
@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.

If you are planning on maintaining @command{ponysay} in your favourite operating
system you should first read @ref{Required runtime dependencies} and
@ref{Optional runtime dependencies}. If your OS does not follow 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 the
option @option{--everything}. Otherwise only the @command{info} manual and the
English manpage will be installed for documentation.
Please inform us about your distribution so we can list it so everypony can see it.
