NAME

ARGV::ENV - Parse an environment variable and unshift into @ARGV

VERSION

version 1.00

SYNOPSIS

From one-liners (see perlrun):

perl -MARGV::ENV=VAR1,VAR2,... -E "..." ...

From a script:

use ARG::ENV qw<VAR1 VAR2>;
...

DESCRIPTION

This module searches the first non-empty environment variable with one of the names given at import time, parses it like the Unix shell (using Text::ParseWords::shellwords) and insert the result at the beginning of @ARGV.

This module is helpful to implement command-line scripts that take some global config as an environnement variable containing command-line flags.

This module is named ARGV::ENV (and not Argv::Env or @ARGV::Env) because the perl built-in global variables @ARGV and @ENV are both in upper case.

SEE ALSO

Some other modules that add magic to @ARGV: ARGV::URL, ARGV::Abs, ARGV::readonly, Encode::Argv.
