## Coding style
-When writing code it is generally a good idea to try and match your
-formatting to that of any existing code in the same file, or to other
-similar files if you are writing new code. Consistency of layout is
-far more important than the layout itself as it makes reading code
-much easier.
+We use [Rubocop](https://github.com/rubocop-hq/rubocop) (for ruby files)
+and [ERB Lint](https://github.com/Shopify/erb-lint) (for erb templates)
+to help maintain consistency in our code. You can run these utilities during
+development to check that your code matches our guidelines:
-One golden rule of formatting -- please don't use tabs in your code
-as they will cause the file to be formatted differently for different
-people depending on how they have their editor configured.
+```
+bundle exec rubocop
+bundle exec rake eslint
+bundle exec erblint .
+```
## Testing
in giving others confidence in the code you've written, and can
greatly speed up the process of merging in new code.
-When hacking, you should:
+When contributing, you should:
* Write new tests to cover the new functionality you've added.
* Where appropriate, modify existing tests to reflect new or changed
You can run the existing test suite with:
```
-bundle exec rake test
+bundle exec rails test:all
```
-You can generate test coverage stats with:
+You can view test coverage statistics by browsing the `coverage` directory.
+
+The tests are automatically run on Pull Requests and other commits via github
+actions. The results shown are within the PR display on github.
+
+## Static Analysis
+
+We also perform static analysis of our code. You can run the analysis yourself with:
```
-sudo gem install rcov
-rcov -x gems test/*/*.rb
+bundle exec brakeman -q
```
-The tests are automatically run on Pull Requests and other commits with the
-results shown on [Travis CI](https://travis-ci.org/openstreetmap/openstreetmap-website).

## Comments
Sometimes it's not apparent from the code itself what it does, or,
developers to read the code and satisfy themselves that it's doing the
right thing.
-When hacking, you should:
+When contributing, you should:
-* Comment your code - don't go overboard, but explain the bits which
+* Comment your code where necessary - explain the bits which
might be difficult to understand what the code does, why it does it
and why it should be the way it is.
* Check existing comments to ensure that they are not misleading.
-## Code Documentation
+## i18n
-To generate the HTML documentation of the API/rails code, run the command
+If you make a change that involve the locale files (in `config/locales`) then please
+only submit changes to the `en.yml` file. The other files are updated via
+[Translatewiki](https://translatewiki.net/wiki/Translating:OpenStreetMap) and should
+not be included in your pull request.
-```
-rake doc:app

+### Nominatim prefixes
+
+I18n keys under the `geocoder.search_osm_nominatim` keyspace are managed by the
+Nominatim maintainers. From time to time they run stats over the Nominatim
+database, and update the list of available keys manually.
+
+Adding or removing keys to this list is therefore discouraged, but contributions
+to the descriptive texts are welcome.
## Committing
-When you submit patches, the project maintainer has to read them and
+When you submit your changes, the project maintainers have to read them and
understand them. This is difficult enough at the best of times, and
-misunderstanding patches can lead to them being more difficult to

+commit.
When writing commit messages please try and stick to the same style as
other commits, namely:
For simple commits the one line summary is often enough and the body
of the commit message can be left out.
-## Sending the patches
+## Pull Requests
If you have forked on GitHub then the best way to submit your patches is to
push your changes back to GitHub and then send a "pull request" on GitHub.
-Otherwise you should either push your changes to a publicly visible git repository
-and send the details to the [rails-dev](http://lists.openstreetmap.org/listinfo/rails-dev)
-list or generate patches with `git format-patch` and send them to the
-[rails-dev](http://lists.openstreetmap.org/listinfo/rails-dev) list.
+If your pull request is small, for example one or two commits each containing
+only a few lines of code, then it is easy for the maintainers to review.
+
+If you are creating a larger pull request, then please help the maintainers
+with making the reviews as straightforward as possible:
+
+* The smaller the PR, the easier it is to review. In particular if a PR is too
+ large to review in one sitting, or if changes are requested, then the
+ maintainer needs to repeatedly re-read code that has already been considered.
+* The commit history is important. This is a large codebase, developed over many
+ years by many developers. We frequently need to read the commit history (e.g.
+ using `git blame`) to figure out what is going on. So small, understandable,
+ and relevant commits are important for other developers looking back at your
+ work in future.
+
+If you are creating a large pull request then please:
+
+* Consider splitting your pull request into multiple PRs. If part of your work
+ can be considered standalone, or is a foundation for the rest of your work,
+ please submit it separately first.
+* Avoid including "fixup" commits. If you have added a fixup commit (for example
+ to fix a rubocop warning, or because you changed your own new code) please
+ combine the fixup commit into the commit that introduced the problem.
+ `git rebase -i` is very useful for this.
+* Avoid including "merge" commits. If your PR can no longer be merged cleanly
+ (for example, an unrelated change to Gemfile.lock on master now conflicts with
+ your PR) then please rebase your PR onto the latest master. This allows you to
+ fix the conflicts, while keeping the PR a straightforward list of commits. If
+ there are no conflicts, then there is no need to rebase anything.
