Summary: Ref T7785. Convert the Cowsay Remarkup rule to use a PHP implementation so we don't have to execute an external `cowsay` binary. I removed some of the default ".cow" files that come with Cowsay because they: - include Perl code which we can not interpret; or - are primarily in-jokes or standalone visual puns or artwork rather than usable actors on the grand stage of cowsay; or - offended my delicate sensibilities. Users can add new cows to `resources/cows/custom/` if they want to make new cows available. I have included a majestic original artwork depicting the "Companion Cube" character from //Portal//.

.SH DESCRIPTION
|
|
.I Cowsay
|
|
generates an ASCII picture of a cow saying something provided by the
|
|
user. If run with no arguments, it accepts standard input, word-wraps
|
|
the message given at about 40 columns, and prints the cow saying the
|
|
given message on standard output.
|
|
.PP
|
|
To aid in the use of arbitrary messages with arbitrary whitespace,
|
|
use the
|
|
.B \-n
|
|
option. If it is specified, the given message will not be
|
|
word-wrapped. This is possibly useful if you want to make the cow
|
|
think or speak in figlet(6). If
|
|
.B \-n
|
|
is specified, there must not be any command-line arguments left
|
|
after all the switches have been processed.
|
|
.PP
|
|
The
|
|
.B \-W
|
|
specifies roughly (where the message should be wrapped. The default
|
|
is equivalent to
|
|
.B \-W 40
|
|
i.e. wrap words at or before the 40th column.
|
|
.PP
|
|
If any command-line arguments are left over after all switches have
|
|
been processed, they become the cow's message. The program will not
|
|
accept standard input for a message in this case.
|
|
.PP
|
|
There are several provided modes which change the appearance of the
|
|
cow depending on its particular emotional/physical state. The
|
|
.B \-b
|
|
option initiates Borg mode;
|
|
.B \-d
|
|
causes the cow to appear dead;
|
|
.B \-g
|
|
invokes greedy mode;
|
|
.B \-p
|
|
causes a state of paranoia to come over the cow;
|
|
.B \-s
|
|
makes the cow appear thoroughly stoned;
|
|
.B \-t
|
|
yields a tired cow;
|
|
.B \-w
|
|
is somewhat the opposite of
|
|
.BR \-t ,
|
|
and initiates wired mode;
|
|
.B \-y
|
|
brings on the cow's youthful appearance.
|
|
.PP
|
|
The user may specify the
|
|
.B \-e
|
|
option to select the appearance of the cow's eyes, in which case
|
|
the first two characters of the argument string
|
|
.I eye_string
|
|
will be used. The default eyes are 'oo'. The tongue is similarly
|
|
configurable through
|
|
.B \-T
|
|
and
|
|
.IR tongue_string ;
|
|
it must be two characters and does not appear by default. However,
|
|
it does appear in the 'dead' and 'stoned' modes. Any configuration
|
|
done by
|
|
.B \-e
|
|
and
|
|
.B \-T
|
|
will be lost if one of the provided modes is used.
|
|
.PP
|
|
The
|
|
.B \-f
|
|
option specifies a particular cow picture file (``cowfile'') to
|
|
use. If the cowfile spec contains '/' then it will be interpreted
|
|
as a path relative to the current directory. Otherwise, cowsay
|
|
will search the path specified in the
|
|
.B COWPATH
|
|
environment variable.
|
|
To list all cowfiles on the current
|
|
.BR COWPATH ,
|
|
invoke
|
|
.B \*(nm
|
|
with the
|
|
.B \-l
|
|
switch.
|
|
.PP
|
|
If the program is invoked as
|
|
.B cowthink
|
|
then the cow will think its message instead of saying it.
|
|
.PP
|
|
.SH COWFILE FORMAT
|
|
A cowfile is made up of a simple block of
|
|
.BR perl (1)
|
|
code, which assigns a picture of a cow to the variable
|
|
.BR $the_cow .
|
|
Should you wish to customize the eyes or the tongue of the cow,
|
|
then the variables
|
|
.B $eyes
|
|
and
|
|
.B $tongue
|
|
may be used. The trail leading up to the cow's message balloon is
|
|
composed of the character(s) in the
|
|
.B $thoughts
|
|
variable. Any backslashes must be reduplicated to prevent
|
|
interpolation. The name of a cowfile should end with
|
|
.BR .cow ,
|
|
otherwise it is assumed not to be a cowfile. Also, at-signs (``@'')
|
|
must be backslashed because that is what Perl 5 expects.

.SH COMPATIBILITY WITH OLDER VERSIONS
|
|
.PP
|
|
What older versions? :-)
|
|
.PP
|
|
Version 3.x is fully backward-compatible with 2.x versions. If
|
|
you're still using a 1.x version, consider upgrading. And tell me
|
|
where you got the older versions, since I didn't exactly put them
|
|
up for world-wide access.
|
|
.PP
|
|
Oh, just so you know, this manual page documents version \*(Vn of
|
|
cowsay.
|
|
.SH ENVIRONMENT
|
|
The COWPATH environment variable, if present, will be used to search
|
|
for cowfiles. It contains a colon-separated list of directories,
|
|
much like
|
|
.B PATH or
|
|
.BR MANPATH .
|
|
It should always contain the
|
|
.B /usr/local/share/cows
|
|
directory, or at least a directory with a file called
|
|
.B default.cow
|
|
in it.
|
|
.SH FILES
|
|
.B %PREFIX%/share/cows
|
|
holds a sample set of cowfiles. If your
|
|
.B COWPATH
|
|
is not explicitly set, it automatically contains this directory.
