Discussion:

When the test suite has a test case that is expected to fail and does indeed fail it prints "FAIL", which can be interpreted as " the test failed, which is a thing we don't want". William will make an issue.

Discussion

New script for testing multiple repositories at once seems promising, make it output the PR-groups to the log, then experiment with automatically committing and pushing to a repository when the run has completed.

    • We like, merge.

Old PRs left to merge

• Miking: 876
• Miking-DPPL: 189

Discussion

We discussed microbenchmarks for external arrays. We should switch from Tensor to external array-based vectors and matrices, although this does not solve all performance problems. We need to look into how we generate OCaml code to be on par with OCaml. We will start by implementing a Bigarrays-based matrix library and move to using that library instead of tensors in coreppl/treeppl. We should also remove tensors from the documentation.

Pull Requests

• Viktor:
  • https://github.com/miking-lang/miking/pull/897
    • We like
  • https://github.com/miking-lang/miking/pull/898
    • We like
  • https://github.com/miking-lang/miking/pull/899
    • We like
  • https://github.com/miking-lang/miking/pull/900
    • Add a named variable for the magic constant 4. Then we like.
  • https://github.com/miking-lang/miking/pull/902
    • We like, but there is a discussion to be had how we should treat Ref and Symbol compared to Int, Float, etc. Should we have a TySymbol AST node or should all be created as TyCon? Add it as a separate issue.
  • https://github.com/miking-lang/miking/pull/901
    • (Includes all the PRs above)
    • Now there is a generate-utest.mc, in addition to utest-generate.mc. Should aim to remove utest-generate.mc in the future when we can.
    • On a separate note, would also be good to have a test that checks that utest are actually running.
    • Viktor need to remove some debugging things, then we like.
  • https://github.com/miking-lang/miking-dppl/pull/192
    • We discussed this PR, but there are still things to be done. Will present again at a later date when it is ready.

Meeting Notes 2025-01-23

Note-taker: Viktor Palmkvist

Participants: Lars Hummelgren, Oscar Eriksson, Viktor Palmkvist, Tim Virgoulay, John Wikman, Gizem Çaylak, David Broman, Anders Ågren Thuné

Pull Requests

• Tim: https://github.com/miking-lang/miking-dppl/pull/191
  • Implement fallback to prior distributino if no explicit drift-kernel is supported. Add a test that is fast and included in normal test suite, but is much less precise. Also fix Oscar's comment. Then we like.
• Oscar: https://github.com/miking-lang/miking/pull/896
  • We like

Discussions Proposal: remove tensors as a built-in part of the language. Refactor or remove dependent code, primarily shifting to use externals that implement vectors and matrixes directly. Oscar can write that library.
