local::lib - create and use a local lib/ for perl modules with PERL5LIB
In code -
use local::lib; # sets up a local lib at ~/perl5 use local::lib '~/foo'; # same, but ~/foo # Or... use FindBin; use local::lib "$FindBin::Bin/../support"; # app-local support library
From the shell -
$ perl -Mlocal::lib export MODULEBUILDRC=/home/username/perl/.modulebuildrc export PERL_MM_OPT='INSTALL_BASE=/home/username/perl' export PERL5LIB='/home/username/perl/lib/perl5:/home/username/perl/lib/perl5/i386-linux' export PATH="/home/username/perl/bin:$PATH"
To bootstrap if you don't have local::lib itself installed -
$ perl -MCPAN -eshell # you only need to do this if you don't have a ~/.cpan cpan> exit <download local::lib tarball from CPAN, unpack and cd into dir> $ perl Makefile.PL --bootstrap $ make test && make install $ echo 'eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)' >>~/.bashrc # Or for C shells... $ /bin/csh % echo $SHELL /bin/csh % perl -I$HOME/perl5/lib/perl5 -Mlocal::lib >> ~/.cshrc
You can also pass --boostrap=~/foo to get a different location (adjust the bashrc / cshrc line appropriately)
This module provides a quick, convenient way of bootstrapping a user-local Perl module library located within the user's home directory. It also constructs and prints out for the user the list of environment variables using the syntax appropriate for the user's current shell (as specified by the
SHELLenvironment variable), suitable for directly adding to one's shell configuration file.
More generally, local::lib allows for the bootstrapping and usage of a directory containing Perl modules outside of Perl's
@INC. This makes it easier to ship an application with an app-specific copy of a Perl module, or collection of modules. Useful in cases like when an upstream maintainer hasn't applied a patch to a module of theirs that you need for your application.
On import, local::lib sets the following environment variables to appropriate values:
PATH is appended to, rather than clobbered.
These values are then available for reference by any code after import.
Rather basic shell detection. Right now anything with csh in its name is assumed to be a C shell or something compatible, and everything else is assumed to be Bourne. If the
SHELLenvironment variable is not set, a Bourne-compatible shell is assumed.
Bootstrap is a hack and will use CPAN.pm for ExtUtils::MakeMaker even if you have CPANPLUS installed.
Kills any existing PERL5LIB, PERL_MM_OPT or MODULEBUILDRC.
Should probably auto-fixup CPAN config if not already done.
Patches very much welcome for any of the above.
local::lib looks at the user's
SHELLenvironment variable when printing out commands to add to the shell configuration file.
