Overview

This class implements a source for Git environments.

A Git source generates environments by locally caching the given Git repository and enumerating the branches for the Git repository. Branches are mapped to environments without modification.

Constructor Details

#initialize(name, basedir, options = {}) ⇒ Git

Initialize the given source.

Parameters:

  • name (String) —

    The identifier for this source.

  • basedir (String) —

    The base directory where the generated environments will be created.

  • options (Hash) (defaults to: {}) —

    An additional set of options for this source.

Options Hash (options):

  • :prefix (Boolean, String) —

    If a String this becomes the prefix. If true, will use the source name as the prefix. Defaults to false for no environment prefix.

  • :remote (String) —

    The URL to the base directory of the SVN repository

  • :remote (Hash) —

    Additional settings that configure how the source should behave.
