Here are some examples of how to use `fetchGit`.
builtins.fetchGit {
url = "git@github.com:my-secret/repository.git";
ref = "master";
rev = "adab8b916a45068c044658c4158d81878f9ed1c3";
}
- To fetch a private repository over SSH:
builtins.fetchGit {
url = "git@github.com:my-secret/repository.git";
ref = "master";
rev = "adab8b916a45068c044658c4158d81878f9ed1c3";
}
builtins.fetchGit {
url = "https://github.com/NixOS/nix.git";
ref = "refs/heads/0.5-release";
}
- To fetch an arbitrary reference:
builtins.fetchGit {
url = "https://github.com/NixOS/nix.git";
ref = "refs/heads/0.5-release";
}
If the revision you're looking for is in the default branch of the
git repository you don't strictly need to specify the branch name in
the `ref` attribute.
- If the revision you're looking for is in the default branch of
the git repository you don't strictly need to specify the branch
name in the `ref` attribute.
However, if the revision you're looking for is in a future
branch for the non-default branch you will need to specify the
the `ref` attribute as well.
builtins.fetchGit {
url = "https://github.com/nixos/nix.git";
rev = "841fcbd04755c7a2865c51c1e2d3b045976b7452";
ref = "1.11-maintenance";
}
> **Note**
>
> It is nice to always specify the branch which a revision
> belongs to. Without the branch being specified, the fetcher
> might fail if the default branch changes. Additionally, it can
> be confusing to try a commit from a non-default branch and see
> the fetch fail. If the branch is specified the fault is much
> more obvious.

for the non-default branch you will need to specify the the `ref`
attribute as well.
- If the revision you're looking for is in the default branch of
the git repository you may omit the `ref` attribute.

}
- To fetch a specific tag:
builtins.fetchGit {
url = "https://github.com/nixos/nix.git";
ref = "refs/tags/1.9";
}

`builtins.fetchGit` can behave impurely fetch the latest version of
a remote branch.
