Create and maintain local registries for Julia packages. This package is intended to provide a simple workflow for maintaining local registries (private or public) without making any assumptions about how the registry or the packages are hosted.

For registration in the General registry, see Registrator.

For serving local packages through a Package Server see the companion package LocalPackageServer.


This package requires Julia 1.6 or later. Older versions of the package work back to Julia 1.1.


You need to have command line git installed and available in the system PATH. If

run(`git --version`)

in the Julia REPL prints a version number rather than giving an error, you are good to go.


using Pkg
pkg"add LocalRegistry"

Create Registry

using LocalRegistry
create_registry(name, repository_url, description = "My private registry")

This prepares a registry with the given name in the standard location for registries. Review the result and git push it manually. When created in this way the registry is automatically activated and the next section can be skipped.

The repository at repository_url must be able to be pushed to, for example by being a bare repository. repository_url itself can be an URL, or a path to a local git repository.

The registry can also be created at a specified path, with a specified branch, or being automatically pushed. See the documentation string for details.

Add Registry

To activate the registry, do

using Pkg
pkg"registry add <repository url>"

This only needs to be done once per Julia installation. Troubleshooting advice if you cannot find packages from the General registry.

Register a Package

using LocalRegistry
register(package; registry = registry)

Register the new package in the registry registry. The version number and other information is obtained from the package's Project.toml. The easiest way to specify package and registry is by name as strings. See the documentation string for more options.


  • You need to have a clean working copy of your registry.
  • The package must be stored as a git working copy, e.g. having been cloned with Pkg.develop.
  • The package must be available in the current Pkg environment.
  • The package must have a Project.toml or JuliaProject.toml file.
  • There is no checking that the dependencies are available in any registry.
  • If you have exactly one installed registry beside the General registry, it is not necessary to specify registry.
  • By default the registry changes are git pushed to the upstream registry repository.

Register a New Version of a Package

using LocalRegistry

When adding a new version of a package, the registry can be omitted. The new version number is obtained from the version field of the package's Project.toml file.

Simplified Registration of Active Package or Current Directory

If you start Julia with the --project flag or use Pkg.activate to activate a developed package, this package can be registered simply by

using LocalRegistry

This is also sufficient for registering a new package, provided that you have exactly one installed registry beside the General registry.

If you run register() but the active project is not a package, it will look for a package in the current directory.
