Honour PEP 8: Style Guide for Python Code
|
||
|
|
-----------------------------------------
|
||
|
|
|
||
|
|
First of all, if you haven't already read it, read the `PEP 8
|
||
|
|
Style Guide for Python Code`_ which, if in doubt, serves as
|
||
|
|
the default coding-style for the py lib.
|
||
|
|
|
||
|
|
Documentation and Testing
|
||
|
|
-------------------------
|
||
|
|
|
||
|
|
- generally we want to drive and interweave coding of
|
||
|
|
documentation, tests and real code as much as possible.
|
||
|
|
Without good documentation others may never know about
|
||
|
|
your latest and greatest feature.
|
||
|
|
|
||
|
|
naming
|
||
|
|
------
|
||
|
|
|
||
|
|
- directories, modules and namespaces are always **lowercase**
|
||
|
|
|
||
|
|
- classes and especially Exceptions are most often **CamelCase**
|
||
|
|
|
||
|
|
- types, i.e. very widely usable classes like the ``py.path``
|
||
|
|
family are all lower case.
|
||
|
|
|
||
|
|
- never use plural names in directory and file names
|
||
|
|
|
||
|
|
- functions/methods are lowercase and ``_`` - separated if
|
||
|
|
you really need to separate at all
|
||
|
|
|
||
|
|
- it's appreciated if you manage to name files in a directory
|
||
|
|
so that tab-completion on the shell level is as easy as possible.
|
||
|
|
|
||
|
|
|
||
|
|
committing
|
||
|
|
----------
|
||
|
|
|
||
|
|
- adding features requires adding appropriate tests.
|
||
|
|
|
||
|
|
- bug fixes should be encoded in a test before being fixed.
|
||
|
|
|
||
|
|
- write telling log messages because several people
|
||
|
|
will read your diffs, and we plan to have a search facility
|
||
|
|
over the py lib's subversion repository.
|
||
|
|
|
||
|
|
- if you add ``.txt`` or ``.py`` files to the repository then
|
||
|
|
please make sure you have ``svn:eol-style`` set to native.
|
||
|
|
which allows checkin/checkout in native line-ending format.
|
||
|
|
|
||
|
|
Miscellaneous
|
||
|
|
-------------
|
||
|
|
|
||
|
|
- Tests are the insurance that your code will be maintained
|
||
|
|
further and survives major releases.
|
||
|
|
|
||
|
|
- Try to put the tests close to the tested code, don't
|
||
|
|
overload directories with names.
|
||
|
|
|
||
|
|
- If you think of exporting new py lib APIs, discuss it first on the
|
||
|
|
`py-dev mailing list`_ and possibly write a chapter in our
|
||
|
|
`future_` book. Communication is considered a key here to make
|
||
|
|
sure that the py lib develops in a consistent way.
