# Bundler-MultiGem The utility to install multiple versions of the same ruby gem ## Usage ### Setup Assuming that you have already installed CPAN: `curl -L http://cpanmin.us | sudo perl - --sudo App::cpanminus` >This project is not available yet in CPAN ```bash $ git clone git@github.com:mberlanda/Bundler-MultiGem.git $ perl Build.PL $ sudo ./Build installdeps $ sudo ./Build install ``` This will make available the command `bundle-multigem` ### Initialize The first command you can run is `initialize` or `init`. This takes a `path` as parameter and the following options: option| alias | descriptions ---|---|--- `gem-main-module`|`gm` | provide the gem main module (default: constantize --gem-name) `gem-name`|`gn` | provide the gem name `gem-source`|`gs` | provide the gem source (default: https://rubygems.org) `gem-versions`|`gv` | provide the gem versions to install (e.g: --gv 0.0.1 --gv 0.0.2) `dir-pkg`|`dp` | directory for downloaded gem pkg (default: pkg) `dir-target`|`dt` | directory for extracted versions (default: versions) `cache-pkg`|`cp` | keep cache of pkg directory (default: 1) `cache-target`|`ct` | keep cache of target directory (default: 0) `conf-file`|`f` | choose config file name (default: .bundle-multigem.yml) Example: ``` bundle-multigem initialize --gn jsonschema_serializer --gv 0.5.0 --gv 0.1.0 . ``` This will generate a `.bundle-multigem.yml` in the current path (`.`).
