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,
fetchsvn]
-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
-A, --arg-str same as --arg, but accepts strings instead Nix expressions
-o, --overwrite overwrite arguments in the final output, not taken into
consideration when fetching the hash
-O, --overwrite-str same as --overwrite, but accepts strings instead Nix
expressions
-l, --list-fetchers List all available fetchers
-L, --list-possible-fetchers List all fetchers that can be generated without --fetcher
-s, --list-sep Print out the listed fetchers with the specified separator,
only used when --list-fetchers or --list-possible-fetchers is
specified
-h, --help Print help information (use --help for more detail)
-V, --version Print version information
```
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).
