I am trying to write a derivation, which fetches a repository from GitHub, with submodules, and which has git patches to apply in some of its git submodules.
I tried the following so far:
postUnpack = '' cd $sourceRoot/foo_submodule && git apply foo.patch '';
prePatch = '' cd $sourceRoot/foo_submodule ''; patches = ["foo.patch"];
Is there a recommended approach to do this?
As I am developing using
nix-shell I had to change references to
$sourceRoot in order to avoid permission denied errors as files under the nix/store appear to be read-only or protected from writes.
A related concern I have, is that the
unpackPhase removes the
.git directory and I wonder how this affects the action of applying a git patch, with
git apply ....
