Leave these in the let block so the updater can see them.

If we are talking about the update.sh script, I believe I tested the update functionality and it worked fine. The version is extracted from the Nix package attribute:

currentVersion=$(nix-instantiate --eval -E "with import ./. {}; code-cursor.version or (lib.getVersion code-cursor)" | tr -d '"')

You need to test on Darwin as well. At the moment, this just doesn't build:

Here's a starting point: AppImage and dmg are different formats and use different unpacking tools -- appImageTools.extract vs. undmg. The underlying structure is different too.

Please mark this PR as a draft while you work this out.

How do I test it on Darwin easily? I only have a Linux machine - is there a good way (like emulation)? A simple test suite would be ok? (GitHub runners will be able to run them). I'll see what I can do about this Darwin situation, but not today.

You'll need access to an Apple machine.

One option is to keep the Apple build as it is and only alter the Linux build.

I have specified vscodeVersion that guides the generic builder on how to work with the unpacked code. This affects this conditional that caused the ripgrep patch failure:

vscodeRipgrep =
  if stdenv.hostPlatform.isDarwin then
    if lib.versionAtLeast vscodeVersion "1.94.0" then
      "Contents/Resources/app/node_modules/@vscode/ripgrep/bin/rg"
    else
      "Contents/Resources/app/node_modules.asar.unpacked/@vscode/ripgrep/bin/rg"
  else
    "resources/app/node_modules/@vscode/ripgrep/bin/rg";

@Zaczero this fixes the build on Darwin. Thank you.

How are you testing this on linux?

GitHub runners can provide a build environment but you can't run cursor there obviously. Nix Community provides a darwin builder too, but no GUI access, sadly.

My suggestion would be to wait until you finish your work for the Linux package. Then someone with access to a darwin machine (@sarahec) can clone your branch, make and test the changes needed, then send a PR to your branch or send you their patch file, which you can then apply to your branch.

Once it all works, we can merge.

re: the vscode version, is there a way to detect it from the unpacked sources? I'm thinking of the maintenance burden on upgrade. Autodetection lets us continue to use the upgrade script.

How are you testing this on linux?

In my configuration.nix, I import the package from the fork directory and then add it to my user packages. This also has the benefit of my being quickly able to run the latest code-cursor without waiting for upstream updates by doing them myself.

code-cursor' = pkgs.callPackage .../vscode/cursor.nix { };

GitHub runners can provide a build environment

I think this is the best fallback option. Luckily, this package is popular enough that there are real people with Darwin machines to test it. The beauty of an open-source community.

re: the vscode version, is there a way to detect it from the unpacked sources? I'm thinking of the maintenance burden on upgrade.

I don't know, but I also don't see it as a maintenance burden. The generic builder only has 1 version conditional that is quite loose. So far, Cursor has received about 2 base VSCode updates per year. Even if it's not up to date, it won't really matter. I have checked how Windsurf does that, and apparently they provide the VSCode version via the update API; Cursor does not.
