can select cpanm "-l" or "-L"

[masaki]

allow following option:

carton install --skip-installed

it selects cpanm options -l | --local-lib and -L | --local-lib-contained.
(-l can skip already installed modules)

Is this to speed up installations or for any other specific purpose?

[masaki]

To speed up installations.
Carton 1.x series does not use "lib::core::only" no longer. So, I think it's not necessary to use "-L" option.

Hm that kind of defeats the purpose of Carton if i understand correctly.

carton install should always use the -L option, to install modules the exact same version in the snapshot, even they are satisfied in site_perl. For instance if you have Moose 1.20 in your site_perl and your cpanfile has requires "Moose", "1.10", using -l will skip the installation even though the snapshot might have 1.11.

if all you need is to speed up the installation on updates, you can use the shared installation path using PERL_CARTON_PATH so that deploying a new version of the app into a different directory (with capistrano style) will not install the whole modules again.

I already tried the capistrano style that's fine. but at 1st time, I spent 10 minutes to install modules at my integration test repository for Jenkins jobs. so, my concern was toward to speed up 😄

For instance if you have Moose 1.20 in your site_perl and your cpanfile has requires "Moose", "1.10", > using -l will skip the installation even though the snapshot might have 1.11.

oh, I missed that case. thanks.
