To use this script, you must be in the root directory of a Rails project that | |
is using git. You should also make sure that your directory does not contain any | |
uncommitted changes. Then run: | |
$ python rails_switch_branch.py name_of_another_branch | |
Running the above will do the following: |
# Be sure to restart your server when you modify this file. | |
# Add new inflection rules using the following format | |
# (all these examples are active by default): | |
# ActiveSupport::Inflector.inflections do |inflect| | |
# inflect.plural /^(ox)$/i, '\1en' | |
# inflect.singular /^(ox)en/i, '\1' | |
# inflect.irregular 'person', 'people' | |
# inflect.uncountable %w( fish sheep ) | |
