Configuration Options

Packages in subdirectories

By default, CompatHelper expects your git repository to contain a single package, and that the Project.toml for that package exists in the top-level directory. You can indicate that you want CompatHelper to process one or many packages that exist in subdirectories of the git repository by passing the subdirs keyword to the main function. For example:

CompatHelper.main(; subdirs=["", "Subdir1", "very/deeply/nested/Subdir2"])

Note that the convention for specifying a top-level directory in the subdirs keyword is [""]

Custom registries

To use a list of custom registries instead of the General registry, use the registries keyword argument. For example:

my_registries = [Pkg.RegistrySpec(name = "General",
                                  uuid = "23338594-aafe-5451-b93e-139f81909106",
                                  url = "https://github.com/JuliaRegistries/General.git"),
                 Pkg.RegistrySpec(name = "BioJuliaRegistry",
                                  uuid = "ccbd2cc2-2954-11e9-1ccf-f3e7900901ca",
                                  url = "https://github.com/BioJulia/BioJuliaRegistry.git")]

CompatHelper.main(; registries=my_registries)

Using the above option will clone the registries, but if you want to use already existing registries, you can use the use_existing_registries option. This will use all the registries present in the user depot, defined as the first entry of the DEPOT_PATH by the Pkg manual.

CompatHelper.main(; use_existing_registries=true)

If you want to use a different location, you can specify that using the depot keyword. Note that the directroy indicated by depot should contain a subdirectory named registries where the registries are stored in order to reproduce the structure of the Julia depot.

Overriding the default branch

By default, CompatHelper will open pull requests against your repository's default branch. If you would like to override this behavior, set the master_branch keyword argument. For example:

CompatHelper.main(; master_branch="my-custom-branch")

EntryType

Define how you want to handle compat entries.

• KeepEntry: Default value, this will keep the existing compat entry for a project and add the new one in addition.
• DropEntry: Choose this to drop the existing compat entry and replace it with the new one.

KeepEntry is the default, but if you like to use DropEntry, you can do the following:

CompatHelper.main(; entry_type=DropEntry())

Unsubscribe from Pull Requests

When a compat Pull Request is created, the user/bot that created the PR will be unsubscribed from the PR that it just created. This is needed in some situations to lower the amount of noise a bot may generate by being subscribed to a PR as any comments/activity will trigger an email/notification for that bot.

Currently this only works for GitLab as it doesn't seem like the GitHub API has an endpoint for this.

CompatHelper.main(; ubsub_from_prs=true)

CC User

When a compat Pull Request is created, you might want the user that generated the PR to be notified which should subscribe them to the PR. This can be used in situations where a user manually triggers a CompatHelper run on GitLab, but has it set up so that the PR is created by a bot. In this case, the user would like to be subscribed to the new PRs.

This will use the GITHUB_ACTOR or GITLAB_USER_LOGIN environment variables to determine which user to mention.

CompatHelper.main(; cc_user=true)
