There are some documents on coding style:
To submit patches to the developers, please use darcs send. You don't need any special permission to do this.
If you have permission to push patches directly to the repository (pretty easy to get, just demonstrate your competence by sending us a patch or two first), then you can use darcs push:
$ darcs push <account>@darcs.haskell.org:/home/darcs/ghc
(change ghc to the name of the repository if you're pushing changes from one of the sub-repositories, like testsuite, or a package such as base. Note: darcs push requires that SSH is working and can log in to your account on darcs.haskell.org.
Do not forget to darcs record your changes first!
When to record/push
Guidelines for pushing patches to GHC:
- We have separate guidelines for proposing changes to standard libraries; see Library Submissions.
- Try to make small patches (i.e. work in consistent increments).
- Separate changes that affect functionality from those that just affect code layout, indendation, whitespace, filenames etc. This means that when looking at patches later, we don't have to wade through loads of non-functional changes to get to the important parts of the patch.
- If possible, push often. This helps to avoid conflicts.
- Rather than push conflicting patches followed by conflict resolutions, use amend-record (or unrecord/edit/record) to make a single patch. Darcs currently doesn't handle conflicts well, so we are trying to keep the HEAD clean of conflicts for now. It doesn't matter so much on the stable branches though.
- Try not to break anything. At the minimum, the tree should build on your system with
the patch, better still test your changes before
pushing. The nightly builds will show up any breakage on other platforms.
If you do end up breaking the build then it's not the end of the world, so don't sweat about it too much. History shows that even people called Simon are not immune from doing so!
- Discuss anything you think might be controversial before pushing it.
