This page documents a couple of points for maintaining the Home Assistant code. Most of the tasks don’t need to be performed on a regular base thus the steps, used tools, or details are preserved here.
+ +Line separator
+ +People are using various operating systems to develop components and platforms for Home Assistant. This could lead to different line endings on file. We prefer LN. Especially Microsoft Windows tools tend to use CRLF.
$ find homeassistant -name "*.py" -exec file {} \; | grep BOM
+$ find homeassistant -name "*.py" -exec file {} \; | grep CRLF
+To fix the line spearator, use dos2unix or sed.
$ dos2unix homeassistant/components/notify/kodi.py
+Dependencies
+ +A lot of components and platforms depends on third-party Python modules. The dependencies which are stored in the requirements_*.txt files are tracked by gemnasium and Requires.io.
If you update the requirements of a component/platform through the REQUIREMENTS = ['modules-xyz==0.3'] entry, run the provided script to update the requirements_*.txt file(s).
$ script/gen_requirements_all.py
+Start a test run of Home Assistant if that was successful include all files in a Pull Request. Add a short summary of the changes, a sample configuration entry, details about the tests, and other useful information to the description.
