1 # Nominatim contribution guidelines
5 Bugs can be reported at https://github.com/openstreetmap/Nominatim/issues.
6 Please always open a separate issue for each problem. In particular, do
7 not add your bugs to closed issues. They may looks similar to you but
8 often are completely different from the maintainer's point of view.
10 ## Workflow for Pull Requests
12 We love to get pull requests from you. We operate the "Fork & Pull" model
15 https://help.github.com/articles/using-pull-requests
17 You should fork the project into your own repo, create a topic branch
18 there and then make one or more pull requests back to the openstreetmap repository.
19 Your pull requests will then be reviewed and discussed. Please be aware
20 that you are responsible for your pull requests. You should be prepared
21 to get change requests because as the maintainers we have to make sure
22 that your contribution fits well with the rest of the code. Please make
23 sure that you have time to react to these comments and amend the code or
24 engage in a conversion. Do not expect that others will pick up your code,
25 it will almost never happen.
27 Please open a separate pull request for each issue you want to address.
28 Don't mix multiple changes. In particular, don't mix style cleanups with
29 feature pull requests. If you plan to make larger changes, please open
30 an issue first or comment on the appropriate issue already existing so
31 that duplicate work can be avoided.
33 ### Using AI-assisted code generators
35 PRs that include AI-generated content, may that be in code, in the PR
36 description or in documentation need to
38 1. clearly mark the AI-generated sections as such, for example, by
39 mentioning all use of AI in the PR description, and
40 2. include proof that you have run the generated code on an actual
41 installation of Nominatim. Adding and excuting tests will not be
42 sufficient. You need to show that the code actually solves the problem
43 the PR claims to solve.
48 Nominatim historically hasn't followed a particular coding style but we
49 are in process of consolidating the style. The following rules apply:
51 * Python code uses the official Python style
54 * all other file types use 4 spaces
55 * [BSD style](https://en.wikipedia.org/wiki/Indent_style#Allman_style) for braces
57 * spaces before and after equal signs and operators
59 * no spaces after opening and before closing bracket
60 * leave out space between a function name and bracket
61 but add one between control statement(if, while, etc.) and bracket
63 The coding style is enforced with pylint. It can be tested with:
66 pylint3 --extension-pkg-whitelist=osmium nominatim
71 Before submitting a pull request make sure that the tests pass:
79 Nominatim follows semantic versioning. Major releases are done for large changes
80 that require (or at least strongly recommend) a reimport of the databases.
81 Minor releases can usually be applied to existing databases. Patch releases
82 contain bug fixes only and are released from a separate branch where the
83 relevant changes are cherry-picked from the master branch.
