moonkale-julia

Julia for Moonkale — today one crate, moonkale-ext-lux: a Lux.jl block library for Moonkale's flow editor. Layers (Dense, Conv, MaxPool, Flatten, Dropout, BatchNorm), activations, an input, a loss and an optimiser, with tensor-shape ports (a shape mismatch is a red wire), and code generation to a Julia file (Lux.Chain(…) plus a training scaffold) that runs with julia model.jl.

It lived in the Moonkale repository as packages/extensions/lux until Milestone 18 (phase 6.4): it is what its author needs, and for everyone else an opt-in extension, so it is off by default and built only when asked for.

Using it

Moonkale pulls it behind an off-by-default feature of its distribution:

# in the Moonkale repository
cd packages/desktop && dx serve --features julia      # or: cargo build -p desktop --features julia
cd packages/web && dx serve --features julia

then switch it on in Settings → Extensions → Lux.jl library; the flow editor's palette gets the Lux blocks, and Generate writes the Julia file. The generated code needs Lux, Optimisers, Zygote and Random in your Julia environment; the extension itself has no Julia dependency.

Developing it

It depends on Moonkale's extension contract by git tag (lib-v1; see Moonkale's packages/ext-api/CHANGELOG.md), so cargo test here builds against that tag. To work on both at once, point Moonkale's distribution at a local checkout ([patch."https://github.com/MathStruct/moonkale-julia"] in Moonkale's Cargo.toml).
