Sardana development guidelines¶
Overview¶
This document describes sardana from the perspective of developers. Most importantly, it gives information for people who want to contribute code to the development of sardana. So if you want to help out, read on!
How to contribute to sardana¶
Sardana development is managed with the Sardana sourceforge project.
Apart from directly contributing code, you can contribute to sardana in many ways, such as reporting bugs or proposing new features. In all cases you will probably need a sourceforge account and you are strongly encouragedto subscribe to the sardana-devel and sardana-users mailing lists <https://sourceforge.net/p/sardana/mailman/>_.
The rest of this document will focus on how to contribute code.
Cloning and forking sardana from Git¶
You are welcome to clone the Sardana code from our main Git repository:
git clone git://git.code.sf.net/p/sardana/sardana.git sardana
Code contributions (bug patches, new features) are welcome, but the review process/workflow for accepting new code is yet to be discussed. For the moment, use the sardana-devel mailing list for proposing patches.
Note that you can also fork the git repository in sourceforge to get your own sourceforge-hosted clone of the sardana repository to which you will have full access. This will create a new git repository associated to your personal account in sourceforge, so that your changes can be easily shared and eventually merged into the official repository.
The old SVN code repository¶
After the release of Sardana 1.2 the Sardana code was migrated from its previous host in a SVN server to its current Git repository
The old SVN repository is still accessible for reference, but writing has been disabled and its contents are frozen as of 2013-07-31. For development, see the instructions above on cloning from Git
Documentation¶
All standalone documentation should be written in plain text (.rst
) files
using reStructuredText for markup and formatting. All such
documentation should be placed in directory docs/source
of the sardana
source tree. The documentation in this location will serve as the main source
for sardana documentation and all existing documentation should be converted
to this format.
Coding conventions¶
In general, we try to follow the standard Python style conventions as described in Style Guide for Python Code
Code must be python 2.6 compatible
Use 4 spaces for indentation
In the same file, different classes should be separated by 2 lines
use
lowercase
for module names. If possible prefix module names with the wordsardana
(likesardanautil.py
) to avoid import mistakes.use
CamelCase
for class namespython module first line should be:
#!/usr/bin/env python
python module should contain license information (see template below)
avoid poluting namespace by making private definitions private (
__
prefix) or/and implementing__all__
(see template below)whenever a python module can be executed from the command line, it should contain a
main
function and a call to it in aif __name__ == "__main__"
like statement (see template below)document all code using Sphinx extension to reStructuredText
The following code can serve as a template for writing new python modules to sardana:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
