# registry-backup

A command line utility for downloading all .crate files hosted by a Cargo registry server.

Use cases:

- **Backup:** retrieve a registry server's files for backup storage
- **Export:** pull the files so you can host them at another registry server

## Example Usage:

Specify the registry index either as a local path (`--index-path`)...

```console
$ git clone https://github.com/rust-lang/crates.io-index.git
$ registry-backup \
    --index-path crates.io-index \
    --output-path crates.io-crate-files \
    --requests-per-second 10
```

...or as an `--index-url` instead:

```console
$ registry-backup \
    --index-url ssh://git@ssh.shipyard.rs/shipyard-rs/crate-index.git \
    --output-path shipyard-rs-crate-files \
    --requests-per-second 10
```

## Runtime Options

```console
$ ./target/release/registry-backup --help

{{ cli_menu }}
```

## Configuration File

A toml configuration file may be used instead of command line flags. A sample file (`config.toml.sample`) is included. From the example file:

```toml
{{ config_sample }}
```

## Justfile

The repository includes a `justfile` with functionality for building, testing, etc.

Included commands:

```console
$ just --list

{{ just_commands }}
```

The commands that mirror cargo commands (e.g. `just test`) are included for the purpose of convenience, so that various options (e.g. `RUSTFLAGS='-C target-cpu=native`) can be included without typing them out each time.

## Generating `README.md`

This file is generated using a template (`doc/README.tera.md`) rendered using updated outputs of the CLI menu, config sample, and other values.

This version of `README.md` was generated at `{{ generation_time }}` based on git commit `{{ git_commit }}`.

To (re-)generate the `README.md` file, use the justfile command:

```console
$ just generate-readme
```
