Register a Package or a New Version of a Package

Registration of a new package or a new version of a previously registered package are both done with the register function.

The full set of arguments to register is

register(package = nothing;
         registry, commit, push, repo, ignore_reregistration,
         gitconfig, create_gitlab_mr)

although in many cases a no-argument register() call is sufficient.

Notice that LocalRegistry should be installed in the global environment or in some shared environment. It should never be a dependency of the package you want to register, unless the package wraps or extends LocalRegistry functionality.

Positional Argument

package::Union{Nothing, Module, AbstractString}:

The package to be registered can be specified in several ways.

  • If package is omitted or nothing, the active project is used if it is a package. Otherwise the current directory is used if that contains a package.

  • If package is a Module, that is used. It needs to first be loaded by using or import.

  • If package is a string, it can be either a package name or a path. It is considered a path if it contains multiple path components. A path in the current working directory can be specified by starting with "./". If it is a name, it must be available in the active environment.

Notes:

  • To activate a package, either use the Pkg.activate function or start Julia with the --project flag.

  • The package must be stored as a git working copy, e.g. having been cloned with Pkg.develop, and must not contain un-committed changes.

  • The package must have a Project.toml or JuliaProject.toml file. This must include name, uuid, and version fields.

  • To register a new version, the version field in Project.toml must be updated.

  • There is no checking that the package's dependencies are available in some registry. This can be separately verified with registry consistency testing.

Keyword Arguments

registry::Union{Nothing, AbstractString}:

There are a number of ways to specify the registry to register the package in.

  • If registry is omitted or nothing, it is first checked if the package is already registered in exactly one of the installed registries, in which case the new version is also registered there. In case of a new package, there must be exactly one installed registry, which is not General, and that is used.

  • If registry is a string, the first match below is used.

    • It is considered a registry name if it is an exact match for one of the installed registries.
    • It is considered a path if it is an existing path on the local file system.
    • Otherwise it is assumed to be a URL to an upstream registry.

Notes:

  • LocalRegistry needs to work with a git clone of the registry. If that is not already the case, or registry is specified as a URL, a temporary git clone is made for the registration. This requires that both keyword arguments commit and push are true.

  • The registry must not have any un-committed changes, unless the keyword argument commit is false.

commit::Bool:

Whether to git commit the changes made to the registry. Default is true. Only set it to false if you are doing something unusual and know that it's needed.

push::Bool:

Whether to push the commits to the upstream repository. Default is true. Setting it to false is mostly useful if you want to inspect the commits before manually pushing, or if you have decided not to have an upstream repository. It cannot be set to true if the keyword argument commit is false.

repo::Union{Nothing, AbstractString}:

URL to the package repository. This is stored in the registry.

  • If repo is omitted or nothing:

    • If it is a new version of a previously registered package, do not update the repo location.
    • If it is a new package, look up the URL from the package's git remote.

  • If it is a string, set or update the repo location in the registry with the given string.

ignore_reregistration::Bool:

Whether not to give an error if trying to register a previously registered version of the package, unless it is identical to the registered version. Defaults to false. If true, only print an informational message.

Note: The default will likely be changed to true in a future update.

git_config::Dict{<:AbstractString, <:AbstractString}:

Optional configuration parameters for the git command. For interactive use you most likely do not need this. Defaults to an empty dictionary, i.e. no configuration.

For CI purposes it can be useful, e.g. as used in the LocalRegistry tests:

git_config = Dict("user.name" => "LocalRegistryTests",
                  "user.email" => "localregistrytests@example.com")

create_gitlab_mr:

If true, send git push options to create a GitLab merge request. Requires the keyword arguments commit and push to both be true. Default is false. This functionality is mostly useful as part of package CI if hosted on GitLab, to automatically register packages.
