Make caching of installed modules easier #2
Description
I spent some time this evening adding caching of modules installed with this action to one of my projects (rra/rra-c-util). The cache action doesn't support running with sudo, so this required disabling sudo and installing into the local::lib path, which isn't ideal, but it seems to work.
I had to add some inobvious configuration to the action that would be easier if it were encapsulated in a configuration option. Specifically, I needed:
- uses: perl-actions/[email protected]
env:
PERL5LIB: ${{ env.HOME }}/perl5
with:
args: "--local-lib=~/perl5"
path: /usr/bin/cpanm
sudo: false
to make everything work. Setting PERL5LIB was inobvious (cpanm --local-lib=~/perl5 does not set that variable and thus installation of modules that have dependencies that also have to be installed fails), as was needing to pre-install cpanminus with apt-get and then set path. I think the latter is because the default path cannot be written to without using sudo, and maybe there's an easier approach.
Would you be willing to add something like:
with:
local-lib: ~/perl5
that sets both args and the environment variable (after tilde expansion)? Or even a boolean that always uses ~/perl5, since that's what local::lib wants. An option to use the pre-installed cpanm or maybe just switch to a different path when sudo: false would also be useful.
For the record, here's the full working workflow with caching:
