Implementation
The following is the current implementation of this function.
applyPatches =
{ src
, name ? (if builtins.typeOf src == "path"
then builtins.baseNameOf src
else
if builtins.isAttrs src && builtins.hasAttr "name" src
then src.name
else throw "applyPatches: please supply a `name` argument because a default name can only be computed when the `src` is a path or is an attribute set with a `name` attribute."
) + "-patched"
, patches ? [ ]
, prePatch ? ""
, postPatch ? ""
, ...
}@args:
if patches == [ ] && prePatch == "" && postPatch == ""
then src # nothing to do, so use original src to avoid additional drv
else stdenvNoCC.mkDerivation
({
inherit name src patches prePatch postPatch;
preferLocalBuild = true;
allowSubstitutes = false;
phases = "unpackPhase patchPhase installPhase";
installPhase = "cp -R ./ $out";
}
# Carry `meta` information from the underlying `src` if present.
// (optionalAttrs (src?meta) { inherit (src) meta; })
// (removeAttrs args [ "src" "name" "patches" "prePatch" "postPatch" ]));
