tree-sitter-abl

OpenEdge Advanced Business Language (ABL) grammar for tree-sitter.

Warning

While the parser already implements most ABL statements (at least those defined in the reference), the shape of AST nodes is not yet considered stable. The grammar should be treated as experimental, and breaking changes are expected.

Notes

The grammar currently faces a few issues, please keep in mind:

• Tree-sitter generated parser.c (due to high action/state count) exceeds GitHub's 100 MiB file limit, so it is not committed to the repository. It is regenerated from grammar.js on demand:
  • bun install triggers the prepare script (bun run tools/generate.js && bun run tools/minify.js) which creates src/parser.c minified.
  • The CI workflow (.github/workflows/ci.yml) regenerates parser.c before building and testing.
  • The release workflow (.github/workflows/release.yml) regenerates parser.c before building the native (.so) and .wasm artifacts.
  • When publishing to npm, prepare runs at pack time and src/parser.c is included in the tarball via the files allow-list, so registry consumers receive a ready-to-build package.
  • Local development requires Bun because tools/generate.js and tools/minify.js rely on Bun APIs. Run bun run generate to (re)create parser.c.
• Compiling .wasm is impossible without upstream fixes in LLVM, the fix has been merged and the change is expected to come out in clang-22.2 or later, it then needs to be adopted in wasi-sdk (and optionally emscripten).
• During the .wasm build, tree-sitter uses wasm-opt optimization pass on the binary, the pass takes a long time (~16mins), please be patient.
