App::Options is Perl module to combine command line options, environment vars, and option file values (for program configuration). SYNOPSIS #!/usr/local/bin/perl use App::Options; # reads option values into %App::options by default # do something with the options (in %App::options) use DBI; $dsn = "dbi:mysql:database=$App::options{dbname}"; $dbh = DBI->connect($dsn, $App::options{dbuser}, $App::options{dbpass}); ... Get help from the command line (assuming program is named "prog") ... prog -? Option values may be provided on the command line, in environment variables, and option files. (i.e. $ENV{APP_DBNAME} would set the value of %App::options{dbname} by default.) The "dbname" and other options could also be set in one of the following configuration files $HOME/.app/prog.conf $HOME/.app/app.conf $PROGDIR/prog.conf $PROGDIR/app.conf $PREFIX/etc/app/prog.conf $PREFIX/etc/app/app.conf /etc/app/app.conf with a file format like [prog] dbname = prod dbuser = scott dbpass = tiger See below for a more detailed explanation of these and other advanced features. App::Options combines command-line arguments, environment variables, option files, and program defaults to produce a hash of option values..
