=========================== Contributing to Apache Lucy =========================== MAKE A PLAN: If you're looking for something to work on, see the STATUS file for a list of development priorities that the Lucy community has already built consensus around. If you propose to make non-trivial changes to Lucy, especially changes to the public API, send a note to the Lucy developer's list describing your plans: http://lucy.apache.org/mailing_lists.html GET THE CODE: Lucy's codebase is available via Git from git-wip-us.apache.org. Start by creating a clone of the repository: git clone https://git-wip-us.apache.org/repos/asf/lucy.git There is also a mirror on Github. https://github.com/apache/lucy Follow the instructions in INSTALL to set up your local workspace. MAKE CHANGES: Edit the source code as you see fit, then build Lucy and run its test suite. Please bear the following in mind: * All code will eventually need to be portable to multiple operating systems and compilers. (This is a complex requirement and it should not block your contribution.) * All public APIs must be documented. * Code should be formatted according to the style guidelines at <http://wiki.apache.org/lucy/LucyStyleGuide>. * All unit tests must pass. * New code needs to be accompanied by new unit tests. * Simplicity, both in terms of API and implementation, is highly valued within the Lucy development community; the simpler the contribution, the more quickly it can be reviewed and integrated. OPEN AN ISSUE: Lucy's issue-tracker/bug-tracker installation runs Atlassian JIRA and we generally use the term "issue" rather than "bug" because not every contribution fixes a "bug". https://issues.apache.org/jira/browse/LUCY 1. Create a JIRA account for yourself and sign in. 2. Once you have signed in, the "create new issue" link will appear. Either use it to open a new issue or navigate to an existing one as appropriate. 3. To attach files to an issue, use the menu command 'More Actions > Attach Files'. Attaching a file to an issue causes an email notification to be sent to the lucy-issues list signalling that a patch has arrived. Please be patient but persistent while engaging with the Lucy committers who review and apply such patches. CONTRIBUTE A PATCH: The easiest way to create a patch with Git is to capture the output of `git diff`: git diff > my_changes.patch The resulting patch file can then be attached to a JIRA issue. GITHUB PULL REQUESTS Github users may submit pull requests against our mirror: https://github.com/apache/lucy An email notifying the Lucy developers list of your pull request will be triggered automatically.
