radicle-explorer/CONTRIBUTING.md

Contributing

This repository holds two projects, each with its own development guide: explorer/README.md and desktop/README.md. This file covers what applies to both.

• Before adding any code dependencies, check with the maintainers if this is okay.

• Write properly formatted comments: they should be english sentences, eg:

  // Return the current UNIX time.
  

• Follow the guidelines when proposing code changes (see below).

• Write properly formatted git commits (see below).

Proposing changes

When proposing changes via a patch:

• Isolate changes in separate commits to make the review process easier.
• Don't make unrelated changes, unless it happens to be an obvious improvement to code you are touching anyway ("boyscout rule").
• Rebase on master when needed.
• Keep your changesets small, specific and uncontroversial, so that they can be merged more quickly.
• If the change is substantial or requires re-architecting certain parts of the codebase, write an ADR first, in docs/adr/ if it affects the whole repository or in the project's own docs/adr/ otherwise, and get consensus on that before proposing the code changes.

Writing Git commit messages

A properly formed git commit subject line should always be able to complete the following sentence:

 If applied, this commit will _____

For example, the following message is well formed:

 Add support for .gif files

In addition, it should be capitalized and must not include a period. Prefix commits that touch a single component with it: explorer: for the web app, httpd: for radicle-httpd and radicle-search, and desktop: for the desktop app. Commits that span most of the repository have no prefix. Either way, each commit should be understandable, testable and revertable as one coherent change.

When it comes to formatting, here's a model git commit message1:

 Capitalized, short (50 chars or less) summary

 More detailed explanatory text, if necessary.  Wrap it to about 72
 characters or so.  In some contexts, the first line is treated as the
 subject of an email and the rest of the text as the body.  The blank
 line separating the summary from the body is critical (unless you omit
 the body entirely); tools like rebase can get confused if you run the
 two together.

 Write your commit message in the imperative: "Fix bug" and not "Fixed bug"
 or "Fixes bug."  This convention matches up with commit messages generated
 by commands like git merge and git revert.

 Further paragraphs come after blank lines.

 - Bullet points are okay, too.

 - Typically a hyphen or asterisk is used for the bullet, followed by a
   single space, with blank lines in between, but conventions vary here.

 - Use a hanging indent.

Patch labels

Label every new patch with each component it touches, so reviewers and filters can tell the projects apart:

Label	Covers
explorer	the web app in explorer/: src/, http-client/, workers/, its tests and config
desktop	anything under desktop/
httpd	explorer/crates/radicle-httpd/ and explorer/crates/radicle-search/

A patch that touches several components gets several labels. Changes to shared files (.github/, .buildkite/, .ryph/, root docs) get the labels of the components they affect. git push can't set labels, so add them once the patch is open:

rad patch label <patch-id> --add explorer --add httpd

Releases and tags

Each project is released on its own. Release tags are releases/<component>/<version>; the refs/tags/releases/* rule in the repository's identity decides when they become canonical.

Component	How it's released	Tag
Explorer web app	Deployed continuously, no releases or tags	—
radicle-httpd + radicle-search	Together, one version, see explorer/RELEASE.md	releases/httpd/<version>
Desktop app	desktop/scripts/release, see desktop/README.md	releases/desktop/<version>

The older releases/<version> tags (httpd 0.22.0–0.29.0, desktop 0.9.0–0.16.0) are left over from before the two repositories were merged. Never create, match or describe against them; scripts must always match a component's own prefix.
