Semet created SPARK-16992:
-----------------------------
Summary: Pep8 code style
Key: SPARK-16992
URL: https://issues.apache.org/jira/browse/SPARK-16992
Project: Spark
Issue Type: Improvement
Reporter: Semet
Add code style checks and auto formating into the Python code.
Features:
- add a {{.editconfig}} file (Spark's Scala files use 2-spaces indentation,
while Python files uses 4) for compatible editors (almost every editors has a
plugin to support {{.editconfig}} file)
- use autopep8 to fix basic pep8 mistakes
- use isort to automatically sort and organise {{import}} statements and
organise them into logically linked order (see doc here. The most important
thing is that it splits import statements that loads more than one object into
several lines. It send keep the imports sorted. Said otherwise, for a given
module import, the line where it should be added will be fixed. This will
increase the number of line of the file, but this facilitates a lot file
maintainance and file merges if needed.
add a 'validate.sh' script in order to automatise the correction (need isort
and autopep8 installed)
You can see similar script in prod in the Buildbot project
