## `fetchRadiclePatch` {#fetchradiclepatch}



`fetchRadiclePatch` works very similarly to `fetchFromRadicle` with almost the same arguments

expected. However, instead of a `rev` or `tag` argument, a `revision` argument is expected, which

contains the full revision id of the Radicle patch to fetch.



```nix

fetchRadiclePatch {

  seed = "rosa.radicle.xyz";

  repo = "z4V1sjrXqjvFdnCUbxPFqd5p4DtH5"; # radicle-explorer

  revision = "d97d872386c70607beda2fb3fc2e60449e0f4ce4"; # patch: d77e064

  hash = "sha256-ttnNqj0lhlSP6BGzEhhUOejKkkPruM9yMwA5p9Di4bk=";

}

```



## `requireFile` {#requirefile}



`requireFile` allows requesting files that cannot be fetched automatically, but whose content is known.
