This will keep the code base consistent. +vi users are encouraged to give [Vim emulation](http://emacswiki.org/emacs/Evil) ([more +info](https://gitorious.org/evil/pages/Home)) a try. + +Pull requests and branching +--------------------------- + +Use one topic branch per pull request. If you do that, you can add extra commits or fix up +buggy commits via `git rebase -i`, and update the branch. The updated branch will be +visible in the same pull request. Therefore, you should not open a new pull request when +you have to fix your changes. + +Do not commit to master in your fork. + +Provide a clean branch without merge commits. + +Committing your changes +----------------------- + +Please ensure that all commits pass all tests, and do not have extra Dialyzer warnings. +To do that run `make check`. If you didn't build via `make debug` at first, the beam files in +`ebin/` might be missing debug_info required for [xref](http://www.erlang.org/doc/man/xref.html) +and [Dialyzer](http://www.erlang.org/doc/man/dialyzer.html), causing a test +failure. +If that happens, running `make clean` before running `make check` could solve the problem. +If you change any of the files with known but safe to ignore Dialyzer warnings, you may +have to adapt the line number(s) in [dialyzer_reference](dialyzer_reference). If you do that, +do not remove the +leading blank line. + +#### Structuring your commits + +Fixing a bug is one commit. +Adding a feature is one commit. +Adding two features is two commits. +Two unrelated changes is two commits. + +If you fix a (buggy) commit, squash (`git rebase -i`) the changes as a fixup commit into +the original commit. + +#### Writing Commit Messages + +It's important to write a proper commit title and description. The commit title must be +at most 50 characters; it is the first line of the commit text. The second line of the +commit text must be left blank. The third line and beyond is the commit message. You +should write a commit message. If you do, wrap all lines at 72 characters. You should +explain what the commit does, what references you used, and any other information +that helps understanding your changes. + +Basically, structure your commit message like this: + +<pre> +One line summary (at most 50 characters) + +Longer description (wrap at 72 characters) +</pre> + +##### Commit title/summary + +* At most 50 characters +* What was changed +* Imperative present tense (Fix, Add, Change) + * `Fix bug 123` + * `Add 'foobar' command` + * `Change default timeout to 123` +* No period + +##### Commit description + +* Wrap at 72 characters +* Why, explain intention and implementation approach +* Present tense http://git-wip-us.apache.org/repos/asf/couchdb-rebar/blob/71f6e917/README.md ---------------------------------------------------------------------- diff --git a/README.md b/README.md index 3be5091..3ec4a3a 100644 --- a/README.md +++ b/README.md @@ -51,77 +51,7 @@ and you can use rebar to build OTP-compliant apps.
