Rename Developer to Contributor guide - I believe this sounds more inclusive and likely improves the diversity of contributors. Separate translation section clarify external resources Add links to UI/UX and user research repos Separate issue tracker and discussions - I imagine this is part of the confusion for people who report bugs to the discussion tracker.

Some Forgejo repositories that depend on each other have workflows
|
|
that will trigger workflows on other repositories using the
|
|
[cascading-pr](https://code.forgejo.org/actions/cascading-pr/) action.
|
|
|
|
# Use cases and examples
|
|
|
|
## Files copied from other repositories
|
|
|
|
[setup-forgejo](https://code.forgejo.org/actions/setup-forgejo) contains a [copy](https://code.forgejo.org/actions/setup-forgejo/src/branch/main/forgejo-curl.sh) of the [forgejo-curl](https://code.forgejo.org/forgejo/forgejo-curl) script. This script does not have numbered releases and the latest version is the one in the main branch.
|
|
|
|
forgejo-curl has a [workflow](https://code.forgejo.org/forgejo/forgejo-curl/src/branch/main/.forgejo/workflows/cascade-setup-forgejo.yml) that will open a pull request to setup-forgejo to [update the forgejo-curl.sh script it contains](https://code.forgejo.org/forgejo/forgejo-curl/src/branch/main/.forgejo/cascading-pr-setup-forgejo). The forgejo-curl workflow will wait on the setup-forgejo workflow and fail if it does not pass, thus providing additional confirmation that the change under test won't break setup-forgejo once merged.
|
|
|
|
When the PR is merged in forgejo-curl, the corresponding PR in setup-forgejo is left open and ready to be merged with the latest version of the forgejo-curl.sh script.
|
|
|
|
## Verifying an upgrade would work
|
|
|
|
[setup-forgejo](https://code.forgejo.org/actions/setup-forgejo) installs a [runner](https://code.forgejo.org/forgejo/runner/) by default, as [specified in the action.yml](https://code.forgejo.org/actions/setup-forgejo/src/commit/a580cb63b6ce411c3394aff77c7073d4d3e9428c/action.yml#L49) file.
|
|
|
|
The runner has a [workflow](https://code.forgejo.org/forgejo/runner/src/branch/main/.forgejo/workflows/cascade-setup-forgejo.yml) that will open a pull request to setup-forgejo to [update the default version](https://code.forgejo.org/forgejo/runner/src/branch/main/.forgejo/cascading-pr-setup-forgejo) in the action.yml file. The runner workflow will wait on the setup-forgejo workflow and fail if it does not pass, thus providing additional confirmation that the change under test won't break setup-forgejo when it upgrades to using a release that contains the change.
|
|
|
|
When the PR is merged in forgejo-curl, the corresponding PR in setup-forgejo is closed. It is not meant to upgrade setup-forgejo because there is not yet a tag release published with this change.
|
|

# Permissions
|
|
|
|
The cascading-pr action needs a token with write permissions on issues
|
|
and repositories that will allow it to fork the destination repository and
|
|
create a pull request from this fork. It also needs read permission
|
|
on issues and pull requests for the origin repository.
|
|
|
|
The [cascading-pr user](https://code.forgejo.org/cascading-pr) is
|
|
dedicated to providing such tokens.
|
|
|
|
For instance, a personal token named
|
|
`https://code.forgejo.org/forgejo/forgejo-curl/` was created by the
|
|
cascading-pr user. This token was added as two secrets named
|
|
`CASCADING_PR_ORIGIN` and `CASCADING_PR_DESTINATION` in the
|
|
https://code.forgejo.org/forgejo/forgejo-curl/ repository.
|
|
|
|
# Access to secrets
|
|
|
|
The workflow that contains the cascading-pr action needs access to the
|
|
secrets of the repository and must run `on.pull_request_target`. For
|
|
instance:
|
|
|
|
```yaml
|
|
on:
|
|
pull_request_target:
|
|
types:
|
|
- opened
|
|
- synchronize
|
|
- closed
|
|
```
|
|
|
|
# Updating the workflow
|
|
|
|
When the cascading-pr workflow is added or updated in a repository, it
|
|
must be done in a PR from a branch of the repository and not than from
|
|
a forked repository. It runs `on.pull_request_target` and if run from
|
|
a fork it will use the content of the default branch instead of the
|
|
proposed change.
