Guidelines for 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/ * Test the code with "doctest" where it makes sense * when breaking backward compatibility with old configuration files or plugins, please include a temporary workaround code that provides a compatibility layer and mark it with a comment that includes the word "COMPAT". For examples, grep the code for the word "COMPAT". :) Patches ------- Send patches, created with "git format-patch", to the email address hut@hut.pm or open a pull request on GitHub. Please use PGP-encryption for security-relevand patches or messages. The UIDs of my key are `huterich <hut@lavabit.com>` and `hut <hut@hut.pm>`, my fingerprint is `1E9B 36EC 051F F6F7 FFC9 69A7 F08C E1E2 00FB 5CDF` and my full pubkey is at the very bottom of this file. Version Numbering ----------------- Three numbers, A.B.C, where * A changes on a rewrite * B changes when major configuration incompatibilities occur * C changes with each release Starting Points --------------- Good places to read about ranger internals are: * ranger/core/actions.py * ranger/container/fsobject.py About the UI: * ranger/gui/widgets/browsercolumn.py * ranger/gui/widgets/browserview.py * ranger/gui/ui.py Common Changes ============== Adding options -------------- * Add a default value in rc.conf, along with a comment that describes the option. * Add the option to the ALLOWED_SETTINGS dictionary in the file ranger/container/settings.py. Make sure to sort in the new entry alphabetically. * Add an entry in the man page by editing doc/ranger.pod, then rebuild the man page by running "make man" in the ranger root directory The setting is now accessible with self.settings.my_option, assuming self is a subclass of ranger.core.shared.SettingsAware. Adding colorschemes ------------------- * Copy ranger/colorschemes/default.py to ranger/colorschemes/myscheme.py and modify it according to your needs. Alternatively, create a subclass of ranger.colorschemes.default.Default and override the "use" method, as it is done in the "Jungle" colorscheme. * Add this line to your ~/.config/ranger/rc.conf: set colorscheme myscheme Change which programs start which file types -------------------------------------------- Edit the configuration file ~/.config/ranger/rifle.conf. The default one can be obtained by running "ranger --copy-config rifle". Change which file extensions have which mime type ------------------------------------------------- Modify ranger/data/mime.types. You may also add your own entries to ~/.mime.types Change which files are previewed in the auto preview ---------------------------------------------------- In ranger/container/file.py, change the constant PREVIEW_BLACKLIST PGP key ======= You may wish to send the author (hut@hut.pm) PGP-encrypted mails for security-relevant messages. This is the authors key. Save everything from the `BEGIN PGP PUBLIC KEY BLOCK` up until the `END PGP PUBLIC KEY BLOCK` message into a file and import it with `gpg --import <filename>`. ``` -----BEGIN PGP PUBLIC KEY BLOCK-----
