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 $project_dir; myperl bin/app.pl will configure perl in such a way that "lib/**" and "t/lib/**", will all have the preamble defined in ".myperl/modules" and "~/.myperl/always/modules" thanks to the import hooks in lib::with::preamble. If you don't have a ".myperl/modules", myperl will use "~/.myperl/defaults/modules" in place of it. You can configure the directory "$project_dir/.myperl" with "export MYPERL_CONFIG". Running tests, $ myprove t/foo.t And in your "Makefile.PL" - sub MY::postamble { q{distdir: myperl_rewrite myperl_rewrite: create_distdir myperl-rewrite $(DISTVNAME) }; } (warning: this is make - so the indent for the "myperl-rewrite" line needs to be a hard tab) to have the defaults added to the top of ".pm, .t and bin/*" files in your dist when it's built for CPAN. Sometimes though, you want a module to be used during development, but not written into the final dist. A good case for this is "indirect". For this, add "-indirect" in "$project_dir/.myperl/dev-modules". And lastly, you can add "if::minus_e=Some::Module" in "$MYPERL_HOME/defaults/dev-modules" for having "Some::Module" conveniently preloaded for <myperl -e '...'> oneliners - see if::minus_e for how this behaves in detail.
