NAME

smiley - print or explain smileys

SYNOPSIS

smiley [-V] [-e] [-l] [-f] [smiley...]

DESCRIPTION

Smiley is a program for smiley junkies who like to have all the smileys at their fingertips.

The options have the following meaning:

-V: Print the version of the program and the number of faces and definitions.
-e: Explain the face found in the environment variable SMILEY.
-l: Print a listing of all the known smileys, with explanations.
-f: Print a random smiley, face only.
smiley: Explain the given smiley.

When invoked with no arguments, smiley prints a random smiley with an explanation.

EXAMPLE

Here are some ksh(1) functions that put a smiley into your prompt.

ps1sed()

Transform the standard input so that it will display properly when it is made part of PS1 in ksh. (That is, quote ! $ \ if they appear.) These are the transformations:

      !       ->      !!

       $       ->      \$

       \       ->      \\

Note that a ! must be doubled instead of quoted with \ in order to display.


ps1sed()
{
     sed 's/!/&&/g
          s/[$\\]/\\&/g'
}

ps1()

Put a new smiley into PS1. Use ps1sed to make sure any characters in the smiley that are special to the shell are quoted appropriately.

ps1()
{
        export SMILEY="`smiley -f`"
        PS1=`print -r - "$SMILEY" | ps1sed`" "
}

CAVEATS

The list of smileys is the personal collection of the author, so there are bound to be some missing.

Multiline smileys and the ``invisible smiley'' are absent from smiley because the author does not want a multiline or invisible prompt.
