If this is set then :engine also needs to be set. The :engine_version specifies the version of the engine being used.The :engine specifies the Ruby engine to be used.

WHAT IS GIT BASH RUBY PATCH

The :patchlevel specifies the patch level for Ruby.

When setting this up the only required bit of information is the ruby version (in our example 1.9.3).

If the application you are creating requires a specific Ruby version or engine we can set this in the Gemfile. source you specify in the source will override anything you have set using bundle config. You can also set you credentials straight in the Gemfile, of course when you do it this way your details will be committed into version control.

WHAT IS GIT BASH RUBY INSTALL

This will need to be set up by anyone who wants access to install gems using Bundler as it doesn’t go into version control (which is one of the nice things about doing it this way). Some sources you use will require credentials to be set.īundle has a config option that allows you to set a username and password for each source bundle config my_gem_source. You can call #source as a block source '' do gem 'my_gem' gem 'my_other_gem' end Sources with Credentials If a gem is found in more than one global source (this should rarely be the case because you should only really have one source) then you will get a warning explaining which gem source has been used. If nothing has been explicitly set Bundler will look at the sources you have defined, starting at the first one and working down.

If you set up a gem using source, path, or git any dependencies for that gem will look in those locations first before trying anywhere else.

When Bundler attempts to locate a gem it will look first at what has been explicitly set on the gem and use that. We can also define a path for a local gem or a git path for a gem hosted somewhere like GitHub (we will get to these later). Now seems like a good time to discuss source priority.Īs well as defining a source at the top of our Gemfile we can define a source against each gem we are loading in. The only requirement for a source is that it must be a valid Rubygems repository. For 99% of projects that require a Gemfile your source will be set to. It isn’t recommended to have more than one source per project. We use the #source method for doing this. The first thing we need to do is tell the Gemfile where to look for gems, this is called the source. When it is evaluated by Bundler the context it is in allows us access to certain methods that we will use to explain our gem requirements. It is useful to note that your Gemfile is evaluated as Ruby code. Your Gemfile should always be in the root of your project directory, this is where Bundler expects it to be and it is the standard place for any package manager style files to live. A gem is a collection of Ruby code that we can extract into a “collection” which we can call later. What is a Gemfile?Ī Gemfile is a file we create which is used for describing gem dependencies for Ruby programs. In this post I want to dive deep into everything we can do with a Gemfile.

Ruby developers use Gemfiles all the time, and most of us know how to do the basics.
