• fetchFromBitbucket
• fetchFromGitHub
• fetchFromGitLab
• fetchFromGitea
• fetchFromGitiles
• fetchFromRepoOrCz
• fetchFromSourcehut
• fetchgit

Usage

``` Usage: nurl [OPTIONS] [URL] [REV]

Arguments: [URL] URL to the repository to be fetched [REV] the revision or reference to be fetched

Options: -f, --fetcher specify the fetcher function instead of inferring from the URL [possible values: fetchFromBitbucket, fetchFromGitHub, fetchFromGitLab, fetchFromGitea, fetchFromGitiles, fetchFromRepoOrCz, fetchFromSourcehut, fetchgit, fetchhg] -i, --indent extra indentation (in number of spaces) [default: 0] -j, --json output in json format -a, --arg additional arguments to pass to the fetcher -l, --list-fetchers List all available fetchers -L, --list-possible-fetchers List all fetchers that can be generated without --fetcher -h, --help Print help information -V, --version Print version information ```

Comparison to nix-prefetch

• nurl infers the fetcher from the URL. For nix-prefetch, you need to pick the fetcher and supply the arguments manually.
• nix-prefetch relies on FOD which is slow, nurl tries to use alternatives when possible.
• nix-prefetch supports arbitrary expressions (planned for nurl) and file attributes.
• nix-prefetch is more configurable and has an interface similar to nix-build.
• nurl has some nice features dedicated to generated packages (--indent, --list-possible-fetchers).
