NAME
App::MyPerl - Your very own set of perl defaults, on a global or per
project basis
SYNOPSIS
# .myperl/modules
v5.14
strictures
autodie=:all
$ myperl bin/some-script
Runs some-script with the following already loaded
use v5.14;
use strictures;
use autodie qw(:all);
and through the magic of lib::with::preamble, "lib/" and "t/lib/" are
already in @INC but files loaded from there will behave as if they had
those lines in them, too.
It is possible to add global defaults, to all scripts and all "myperl"
projects with "~/.myperl/defaults/modules" and
"~/.myperl/always/modules"
DESCRIPTION
A ".pm or .pl" file usually requires some preamble to get some defaults
right.
# important ones
use strict;
use warnings;
# good
use autodie qw(:all);
# better exceptions
use Try::Tiny;
use Carp;
On top of that you might find Scalar::Util, List::Util useful all over
your code.
"myperl" allows you define this boilerplate once and for all, while
maintaining compatiability with existing code.
TUTORIAL
If there is no "export MYPERL_HOME="~/.perl_defaults"", "~/.myperl" is
by default read for global defaults.
# ~/.myperl/always/modules
strictures
autodie=:all
# ~/.myperl/defaults/modules
v5.14
# ~/some_scripts/script.pl
say "Hello World"
The syntax for the modules file is,
* "comment" -- # comment
* "empty space"
* "Foo=bar,qux,baz" -- This translates to "use Foo qw(bar, qux, baz)"
* "-Foo=bar,qux,baz" -- This translates to "no Foo qw(bar, qux, baz)"
Now,
$ myperl ~/some_scripts/script.pl
will print "Hello World".
Let's say you are working on a typical Perl module like,
.myperl/
lib/
t/
bin/
README
LICENSE
Makefile.PL
...
Now,
$ cd $project_dir; myperl bin/app.pl
will configure perl in such a way that "lib/**" and "t/lib/**", will all
have the preamble defined in ".myperl/modules" and
"~/.myperl/always/modules" thanks to the import hooks in
lib::with::preamble.
If you don't have a ".myperl/modules", myperl will use
"~/.myperl/defaults/modules" in place of it.
