It +takes a gem manifest file and is able to fetch, download, and install the gems +and all child dependencies specified in this manifest. It can manage any update +to the gem manifest file and update the bundled gems accordingly. It also lets +you run any ruby code in context of the bundled gem environment. + +## Disclaimer + +This project is under rapid development. It is usable today, but there will be +many changes in the near future, including to the Gemfile DSL. We will bump up +versions with changes though. We greatly appreciate feedback. + +## Installation + +Bundler has no dependencies. Just clone the git repository and install the gem +with the following rake task: + + rake install + +## Usage + +Bundler requires a gem manifest file to be created. This should be a file named +`Gemfile` located in the root directory of your application. After the manifest +has been created, in your shell, cd into your application's directory and run +`gem bundle`. This will start the bundling process. + +### Manifest file + +This is where you specify all of your application's dependencies. By default +this should be in a file named `Gemfile` located in your application's root +directory. The following is an example of a potential `Gemfile`. For more +information, please refer to Bundler::ManifestBuilder. + + # Specify a dependency on rails. When the bundler downloads gems, + # it will download rails as well as all of rails' dependencies (such as + # activerecord, actionpack, etc...) + # + # At least one dependency must be specified + gem "rails" + + # Specify a dependency on rack v.1.0.0. The version is optional. If present, + # it can be specified the same way as with rubygems' #gem method. + gem "rack", "1.0.0" + + # Specify a dependency rspec, but only activate that gem in the "testing" + # environment (read more about environments later). :except is also a valid + # option to specify environment restrictions. + gem "rspec", :only => :testing + + # Add http://gems.github.com as a source that the bundler will use + # to find gems listed in the manifest. By default, + # http://gems.rubyforge.org is already added to the list. + # + # This is an optional setting. + source "http://gems.github.com" + + # Specify where the bundled gems should be stashed. This directory will + # be a gem repository where all gems are downloaded to and installed to. + # + # This is an optional setting. + # The default is: vendor/gems + bundle_path "my/bundled/gems" + + # Specify where gem executables should be copied to. + # + # This is an optional setting. + # The default is: bin + bin_path "my/executables" + + # Specify that rubygems should be completely disabled. This means that it + # will be impossible to require it and that available gems will be + # limited exclusively to gems that have been bundled. + # + # The default is to automatically require rubygems. There is also a + # `disable_system_gems` option that will limit available rubygems to + # the ones that have been bundled. + disable_rubygems + +### Running Bundler + +Once a manifest file has been created, the only thing that needs to be done +is to run the `gem bundle` command anywhere in your application. The script +will load the manifest file, resole all the dependencies, download all +needed gems, and install them into the specified directory. + +Every time an update is made to the manifest file, run `gem bundle` again to +get the changes installed. This will only check the remote sources if your +currently installed gems do not satisfy the `Gemfile`. If you want to force +checking for updates on the remote sources, use the `--update` option. + +### Running your application + +The easiest way to run your application is to start it with an executable +copied to the specified bin directory (by default, simply bin). For example, +if the application in question is a rack app, start it with `bin/rackup`. +This will automatically set the gem environment correctly. + +Another way to run arbitrary ruby code in context of the bundled gems is to +run it with the `gem exec` command. For example: + + gem exec ruby my_ruby_script.rb + +Yet another way is to manually require the environment file first. This is +located in `[bundle_path]/environments/default.rb`. For example: + + ruby -r vendor/gems/environment.rb my_ruby_script.rb + +### Using Bundler with Rails today + +It should be possible to use Bundler with Rails today. Here are the steps +to follow. + +* In your rails app, create a Gemfile and specify the gems that your + application depends on. Make sure to specify rails as well: + + gem "rails", "2.1.2" + gem "will_paginate" + + # Optionally, you can disable system gems all together and only + # use bundled gems. + disable_system_gems + +* Run `gem bundle` + +* You can now use rails if you prepend `gem exec` to every call to `script/*` + but that isn't fun. + +* At the top of `config/boot.rb`, add the following line: + + require File.expand_path(File.join(File.dirname(__FILE__), '..', 'vendor', 'gems', 'environment')) + +In theory, this should be enough to get going. + +## To require rubygems or not + +Ideally, no gem would assume the presence of rubygems at runtime. Rubygems provides +enough features so that this isn't necessary. However, there are a number of gems +that require specific rubygem features. + +If the `disable_rubygems` option is used, Bundler will stub out the most common +of these features, but it is possible that things will not go as intended quite +yet. So, if you are brave, try your code without rubygems at runtime. + +## Known Issues + +* When a gem points to a git repository, the git repository will be cloned + every time Bundler does a gem dependency resolve. + +## Reporting bugs + +Please report all bugs on the github issue tracker for the project located +at: + + http://github.com/wycats/bundler/issues/
