pre-build orion pre-processor

[castdrian]

is there a way to pre-build the pre-processor? when compiling a tweak via github-actions this step seems to take the longest and I already wrote a docker image that comes with theos and swift, I'd like to ideally also have it have orion precompiled

Cache it

[castdrian]

I'm aware of that, that does not really answer the question if it can be pre-built via cli invocation

the compilation steps that take up the most time are ArgumentParser and a few other dependencies which seem tweak agnostic. So it should seem logical to be able to build those beforehand

Not super familiar with our Swift tooling but it looks like you should be able to pre-build the preprocessor via the swift-bootstraper.pl script.

Example invocation: https://github.com/theos/theos/blob/16f19fb1da4322513a9ad0283c12f418121773d1/makefiles/instance/rules.mk#L246

Thank you

FWIW invoking swift-bootstrapper yourself may work for now but it’s an implementation detail so I wouldn’t recommend relying on it. Consider instead creating a new (temporary) Orion tweak, running make, and then deleting the tweak dir. That should be sufficient to cache the preprocessor in a stable manner.

Cache it

I already have this and it does nothing to cache swift preprocessor

[Luki120]

Yes, it does, I don’t suggest broken code. Your build obviously has to succeed first in order to cache something

I have a cache for the entire theos directory, infact my caching code is pretty much the same as yours, so I don't know why yours works but mine doesn't.

Heres my cache if that helps:

      - name: Check cache
        run: |
          echo upstream_heads=`git ls-remote https://github.com/theos/theos | head -n 1 | cut -f 1`-`git ls-remote https://github.com/theos/sdks | head -n 1 | cut -f 1` >> $GITHUB_ENV

      - name: Restore cache if available
        id: cache
        uses: actions/cache/restore@v4.0.2
        with:
          path: ${{ github.workspace }}/theos
          key: ${{ env.upstream_heads }}

      - name: Setup Theos
        if: steps.cache.outputs.cache-hit != 'true'
        uses: actions/checkout@v4.1.7
        with:
          repository: theos/theos
          path: theos
          submodules: recursive

      - name: Setup iOS SDK
        if: steps.cache.outputs.cache-hit != 'true'
        uses: actions/checkout@v4.1.7
        with:
          repository: theos/sdks
          path: theos/sdks
          sparse-checkout: "iPhoneOS16.5.sdk"
          sparse-checkout-cone-mode: false

      - name: Save cache if needed
        if: steps.cache.outputs.cache-hit != 'true'
        uses: actions/cache/save@v4.0.2
        with:
          path: ${{ github.workspace }}/theos
          key: ${{ env.upstream_heads }}

I even used cache/save to save the cache even if the run fails but downloading theos and it's sdk succeeds.
