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 <FETCHER>       specify the fetcher function instead of inferring from the URL [possible values: fetchFromBitbucket, fetchFromGitHub, fetchFromGitLab, fetchFromGitea, fetchFromGitiles, fetchFromRepoOrCz, fetchFromSourcehut, fetchgit, fetchhg]
  -i, --indent <INDENT>         extra indentation (in number of spaces) [default: 0]
  -j, --json                    output in json format
  -a, --arg <KEY> <VALUE>       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 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).
