Guidelines on Code Modification =============================== Coding Style ------------ * Use syntax compatible to both python 2.6 and 3.1. * Use docstrings with pydoc in mind * Follow the style guide for python code: http://www.python.org/dev/peps/pep-0008/ * Although this guide suggests otherwise, tabs are used for indentation of code and docstrings. In other documents (readme, etc), use spaces. * Test the code with unit tests where it makes sense Patches ------- Send patches, created with "git format-patch", to the email adress romanz@lavabit.com If you plan to do major changes, or many changes over time, I encourage you to create a fork on GitHub, Gitorious or any other site. Starting Points --------------- Good places to read about ranger internals are: ranger/core/actions.py ranger/core/environment.py ranger/fsobject/fsobject.py About the UI: ranger/gui/widgets/browsercolumn.py ranger/gui/widgets/browserview.py ranger/gui/defaultui.py Common Changes -------------- * Change which files are previewed in the auto preview: In ranger/gui/widget/browsercolumn.py the constant PREVIEW_BLACKLIST * Adding options: In ranger/defaults/options.py add the default value, like: my_option = True In ranger/shared/settings.py add the name of your option to the constant ALLOWED_SETTINGS The setting is now accessible at self.settings.my_option, assuming is a "SettingsAware" object. * Changing commands, adding aliases: ranger/defaults/commands.py or ~/.config/ranger/commands.py * Adding colorschemes: Copy ranger/colorschemes/default.py to ranger/colorschemes/myscheme.py and modify it according to your needs. Alternatively, mimic the jungle colorscheme. It subclasses the default scheme and just modifies a few things. In ranger/defaults/options.py (or ~/.config/ranger/options.py), change colorscheme = 'default' to: colorscheme = 'myscheme' * Change which files are considered to be "hidden": In ranger/defaults/options.py change the hidden_filter regular expression. * Change the key map: Modify ranger/defaults/keys.py. This should be self-explanatory. Check out ranger/core/actions.py for the most common actions, of course you can also use your own functions. * Change the file type => application associations: In ranger/defaults/apps.py modify the method app_default. The variable "f" is a filesystem-object with attributes like mimetype, extension, etc. For a full list, check ranger/fsobject/fsobject.py * Change the file extension => mime type associations: Modify ranger/data/mime.types Version Numbering ----------------- X.Y.Z, where: * X: Major version, milestone * Y: Minor version, odd number => stable version * Z: Revision, may be omitted if zero
