Codewarrior and the Perl/Shell Tools

The Perl/Shell Tool is useful - being able to run arbitrary Perl and Shell Scripts during a build is very cool.

CodeWarrior will pass the following enviromental variables to your script.

HOME
LANG
MW_CURRENT_TARGET
MW_OUTPUT_DIRECTORY
MW_OUTPUT_FILE
MW_OUTPUT_NAME
MW_PROJECT_DIRECTORY
MW_PROJECT_FILE
MW_PROJECT_NAME
PATH
SHELL
USER
__CF_USER_TEXT_ENCODING

Some sample values are here:

        CVS_RSH= ssh
        HOME= /Users/aias
        LANG= en_US
        MW_CURRENT_TARGET= Carbon Toolbox Debug
        MW_OUTPUT_DIRECTORY= /Users/aias/Temp/shelltoool
        MW_OUTPUT_FILE= /Users/aias/Temp/shelltoool/Carbon Toolbox Debug
        MW_OUTPUT_NAME= Carbon Toolbox Debug
        MW_PROJECT_DIRECTORY= /Users/aias/Temp/shelltoool
        MW_PROJECT_FILE= /Users/aias/Temp/shelltoool/shelltoool
        MW_PROJECT_NAME= shelltoool
        PATH= /usr/bin:/bin:/usr/sbin:/sbin:/Users/aias
        SHELL= /opt/local/bin/ksh
        USER= aias
        __CF_USER_TEXT_ENCODING= 0x1F5:0:0

We extracted these values with our own little Perl script (based on a script from Greg Tavares post in codewarrior.games on 2003-01-07)

for $key (sort(keys %ENV))
{
   #print ($key, "=", $ENV`[Unknown macro: {$key, "\n"}]`, "n");
   print ("     ", "$key= " . $ENV`[Unknown macro: {$key}]`, "n");
}

print "n";

print $ENV`[Unknown macro: {MW_PROJECT_DIRECTORY}]`;

A bit of power goes a long ways.
