To Think About When Contributing Source Code
|
|
|
|
This document is intended to offer some guidelines that can be useful to
|
|
keep in mind when you decide to write a contribution to the project. This
|
|
concerns new features as well as corrections to existing flaws or bugs.
|
|
|
|
Naming
|
|
|
|
Try using a non-confusing naming scheme for your new functions and variable
|
|
names. It doesn't necessarily have to mean that you should use the same as
|
|
in other places of the code, just that the names should be logical,
|
|
understandable and be named according to what they're used for.
|
|
|
|
Indenting
|
|
|
|
Please try using the same indenting levels and bracing method as all the
|
|
other code already does. It makes the source code a lot easier to follow if
|
|
all of it is written using the same style. I don't ask you to like it, I
|
|
just ask you to follow the tradition! ;-)
|
|
|
|
Commenting
|
|
|
|
Comment your source code extensively. I don't see myself as a very good
|
|
source commenter, but I try to become one. Commented code is quality code
|
|
and enables future modifications much more. Uncommented code much more risk
|
|
being completely replaced when someone wants to extend things, since other
|
|
persons' source code can get quite hard to read.
|
|
|
|
General Style
|
|
|
|
Keep your functions small. If they're small you avoid a lot of mistakes and
|
|
you don't accidentaly mix up variables.
|
|
|
|
Non-clobbering All Over
|
|
|
|
When you write new functionality or fix bugs, it is important that you
|
|
don't fiddle all over the source files and functions. Remember that it is
|
|
likely that other people have done changes in the same source files as you
|
|
have and possibly even in the same functions. If you bring completely new
|
|
functionality, try writing it in a new source file. If you fix bugs, try to
|
|
fix one bug at a time and send them as separate patches.
|
|
|
|
Separate Patches Doing Different Things
|
|
|
|
It is annoying when you get a huge patch from someone that is said to fix 511
|
|
odd problems, but discussions and opinions don't agree with 510 of them - or
|
|
509 of them were already fixed in a different way. Then the patcher needs to
|
|
extract the single interesting patch from somewhere within the huge pile of
|
|
source, and that gives a lot of extra work. Preferably, all fixes that
|
|
correct different problems should be in their own patch with an attached
|
|
description exactly what they correct so that all patches can be selectively
|
|
applied by the maintainer or other interested parties.
|
|
|
|
Document
|
|
|
|
Writing docs is dead boring and one of the big problems with many open
|
|
source projects. Someone's gotta do it. It makes it a lot easier if you
|
|
submit a small description of your fix or your new features with every
|
|
contribution so that it can be swiftly added to the package documentation.
|
|
|
|
Write Access to CVS Repository
|
|
|
|
If you are a frequent contributor, or have another good reason, you can of
|
|
course get write access to the CVS repository and then you'll be able to
|
|
check-in all your changes straight into the CVS tree instead of sending all
|
|
changes by mail as patches. Just ask if this is what you'd want.
