jac nacompile app.jac -o app to build zero-dependency executables with cross-target support for wasm32, Windows, and macOS. - Automatic native promotion: Run jac run --autonative to execute native-compatible code on the LLVM backend with silent Python fallback for unsupported features like walkers or async. - C FFI interop: Declare C-ABI functions and by-value structs in import from blocks to call precompiled libraries such as raylib, with sibling-library resolution via $ORIGIN RUNPATH. - Use Case: A developer has a Jac CLI tool with a hot summation loop. They pin the compute function native, run jac nacompile tool.jac -o tool, and ship the binary alongside its shared library with no Python install required. ## Quick Start Compile my Jac file into a standalone native binary and show me how to call a C library from it.High-intent search queries and answers about installing and using this skill.
Run jac nacompile app.jac -o app to produce a zero-dependency native binary. The file must contain a with entry block as its entry point, and you can cross-target other platforms with --target wasm32, windows, or macos.
Declare the C functions inside an import from block with fixed-width types like i32 or f32, matching the C ABI. The compiler records the library as a DT_NEEDED entry with $ORIGIN RUNPATH, so placing the .so next to the binary lets the OS loader resolve it at runtime.
Walkers, nodes, edges, async, generators, decorators, multiple inheritance, by llm(), and PyPI imports all fail at compile time. Unsupported imports produce explicit errors rather than silently generating broken binaries.
The in operator on list[str] uses pointer comparison and always returns False, even for identical literals. Loop through the list and compare elements with == instead; in works correctly for list[int] and substring checks.
Yes, native sections can live inside a regular .jac file with automatic bidirectional bridging for primitives, collections, and objects. Define Python functions before the native section that calls them, since each codespace only sees its own definitions at compile time.
