local::libs for Dist Development
Most of my distributions are on GitHub and built using Dist::Zilla. As the dependencies of each vary widely and I don’t want to muck up my workstation’s libraries, I set up a local::lib for each distribution’s development.
To bootstrap a new local::lib area, I wrote this simple shell script:
#!/bin/bash # script named "new-ll" if [ -z $1 ] then echo 'pass the distribution name, please' exit fi echo "creating local::lib for $1 ..." sleep 3 curl -L http://cpanmin.us/ | perl - --notest --quiet --local-lib \ ~/perl5/$1 \ App::cpanminus \ Dist::Zilla \ App::local::lib::helper
Entering the correct environment for a distribution uses another helper script:
#!/bin/bash # script named "go" if [ -z $1 ] then echo 'pass the distribution name, please' exit fi ~/perl5/$1/bin/localenv bash
Which means my workflow for a new distribution is:
$ new-ll New-Dist-Name $ go New-Dist-Name
Any Perl distributions installed in that shell (for example from
dzil authordeps | cpanm or
dzil listdeps | cpanm) will be placed into the new local::lib. It’s a simple ^D to exit.
However it’s not obvious that you’re within this special environment, so editing Bash’s
$PS1 variable (the shell prompt) to include the following, can help:
echo $PERL5LIB | cut -d'/' -f5
My deep thanks to the authors of the distributions used to create this neat setup.
