NAME
Dist::HomeDir
SUMMARY
use Dist::HomeDir;
my $dist_home = Dist::Homedir::dist_home(); # A Path::Tiny object of the Dist home
use Dist::HomeDir lib => [qw( script/lib t/lib )];
# @INC now contains $dist_home->child('script/lib') and t/lib
Easily find the dist homedir for an application set up as a cpan(ish)
distribution but intended to be deployed via git checkout or by a
tarball in a self contained directory. You can also optionally modify
@INC as documented above.
DO NOT use this in code that is ever likely to be installed via cpan or
other package manager.
DESCRIPTION
This module was inspired by Catalyst::Utils->home() to obtain the root
directory for obtaining application code and self-contained support
data in directories relative to the distribution root. It does this by
returning a Path::Tiny object which has a very nice interface. However
Catalyst::Utils->home only works for perl classes. This works for class
files and perl scripts via examining (caller)[1] and thus should never
be used in code that will be instaled via a cpan client or other
package manager.
Sometimes support libaries will also live in the t/lib directory and
the script/lib directory. dist_home will ignore these lib directories
as part of finding the distribution root. Future versions of this
module may make the list of what directories to ignore other lib sub
directories user-configurable (patches welcome).
If you want to modify @INC with the import syntax in the second example
<<<<<<< HEAD in the summary, be careful. In particular if you use "
Dist::HomeDir" in test files and in code to be used in production, @INC
might be modified in unexpeted ways depending on the structure of your
codebase. The best thing to do here is only use the import syntax in
test files or maybe other support files (e.g. in script), and never in
code in the main package hierarchy.
FUNCTIONS
dist_home
Returns a Path::Tiny object of where the current code file executed
thinks the distribution home directory is.
ALTERNATIVES
Mojo::Home - lots of features, no non-core perl dependencies
FindBin - perl core, comes with gotchas if called multiple times.
Test::InDistDir - where the import syntax for Dist::HomeDir came from.
