Rbenv-pluger: a rbenv-plugin manager and booter

• manage rbenv plugins like rbenv manage rubies.
• but not a normal plugin, it manage all my ruby life(from install to maintain)

Why

• ruby developed fastly, need multiple ruby versions

• boring with manualy or rvm(heavy)

• dream a daily tool for:

  • consistent installing in home notebook/office pc/vsp server
  • easily manage my ruby life

  rbenv from 37signals maybe your option. I love it, also some plugins.

Install

• Rbenv has not installed(Recommended)

  intall rbenv with this pluger using one shell script in: recipe/rbenv. (Note: tested on ubuntu12.04)

  $ curl -L https://raw2.github.com/cao7113/rbenv-pluger/master/recipe/rbenv|RUBY_VERSION=2.1.0 RUBY_BUILD_CACHE_PATH=~/down bash

• Rbenv has installed: install this like normal rbenv-plugin

Usage

• rbenv help pluger
• rbenv help boot #oh, maybe just work on ubuntu12.04+

Note

share/plug: just shell snippet, sourced when installed!

recipe/: some recipes

etc/rbenv.d: hooks for plugin (supporting before/after_hook)

About rbenv:

• 支持自动完成
• 支持rbenv --debug xxx 选项，相当于设置 RBENV_DEBUG=1并set -x

About ruby-build:

• 使用-kv选项总是好的
• rbenv install [Tab] #类似-l，支持自动补全，赞一个！
• ruby-build可单独使用（高级），选项：--definitions, --lib, --version
• 支持自定义definition file
• rbenv install/uninstall支持before_hook/after_hook，可用于系统依赖的安装？
• 环境变量：
  • RBENV_BUILD_ROOT 存放编译时的源码（-k时），默认为$RBENV_ROOT/sources
  • RUBY_BUILD_CACHE_PATH caching downloaded package files #如$RBENV_ROOT/cache存在，则将此目录设为ruby源码包的缓存之地，在网络不畅达时此项挺有用！

TODO

• 提交到ubuntu中心
• boot的bundle设计，独立出来，借鉴chef？
