|
|
# CEEDLING_MAIN_PROJECT_FILE environment variable before loading the ceedling
|

|
|
# rakefile. A path supplied as an argument to this method will override the
|

|
|
# current value of the environment variable. If no path is supplied as an
|
||
|
|
# argument then the existing value of the environment variable is used. If
|
||
|
|
# the environment variable has not been set and no argument has been supplied

# then a default path of './project.yml' will be used.

# Register a plugin for ceedling to use when a project is loaded. This method

|
# *must* be called prior to calling the _load_project_ method.
|
||
|
|
#
|
||
|
|
# This method is intended to be used for loading plugins distributed via the
|

|
|
# RubyGems mechanism. As such, the following gem structure is assumed for
|
||
|
|
# plugins.
|
||
|
|
#
|
||
|
|
# * The gem name must be prefixed with 'ceedling-' followed by the plugin
|
||
|
|
# name (ex. 'ceedling-bullseye')
|
||
|
|
#
|
||
|
|
# * The contents of the plugin must be isntalled into a subdirectory of
|
||
|
|
# the gem with the same name as the plugin (ex. 'bullseye/')
|
||
|
|
#
|
||
|
|
# === Arguments
