git-crate-registry

git-crate-registry provides a template for hosting a Rust crate registry on a private git server, or local filesystem.

The template provides a Python 3 script, add-crate.py which packages a crate extracts, extacts the neccesary metadata and commits it to this repository.

how to deploy

1. Clone this repository

2. If you do not want to use git lfs, delete .gitattributes from the repository.

3. Replace PATH_TO_MASTER_RAW_FILES in config.json with the URL prefix to download a file from the master branch of your repository. For example:

   • gitlab: http://gitlab.com/USER/REPO/-/raw/master

   • github: https://raw.githubusercontent.com/USER/REPO/master

4. Commit these changes and push it to your git server

adding a crate

Clone the repository to your local machine and run the following

./add-crate.py ../my-crate/
git push

Any compilation errors should be printed to the console. If not, ensure that cargo metadata and cargo package run without error.

using the registry

1. Create or edit the .cargo/config file in either the folder of the project you're importing crates into, or your home folder (~/.cargo/config or %USERPROFILE%\.cargo.config)

2. Add a registry entry pointing at the URL of your registry repository:

   [registries]
   my-registry = { index = "https://mygitserver.local/USERNAME/registry" }

3. In Cargo.toml, declare imported crates by specifying their version and your custom registry name

   [dependencies]
   my_crate = { version = "0.1", registry = "my-registry"}

local filesystem registy

This template can also be used as a local filesystem based crate registry.

To use it in this mode:

1. replace PATH_TO_MASTER_RAW_FILES with a file:// URI pointing at the registry's location on the filesystem. e.g.

   {
       "dl": "file:///Users/USERNAME/projects/registry/crates/{crate}/{crate}-{version}.crate"
   }

2. Create a registry entry in `.cargo/config` with a `file://` URI pointing at the registry's
   location. e.g.
    ```toml
    [registries]
    my-registry = { index = "file:///Users/USERNAME/projects/registry" }
    ``` 

debugging notes

If cargo is having issues resolving packages in your registry:

1. Remove the cached registry from ~/.cargo/registry/index/

2. Set the variable export CARGO_LOG=cargo::sources

3. Rerun your cargo command (e.g. cargo build)
