TSLexia

TSLexia is a Scintilla lexer that makes use of Tree-sitter parsers.

Compile

TSLexia requires only a C compiler and a C++ compiler that supports C++17.

make deps
make # or 'make win' for Windows dlls
make parsers

There are now libtslexia.so and libtree-sitter-[name].so (or TSLexia.dll and tree-sitter-[name].dll) libraries you can use with your Scintilla application.

Usage

1. In your application, #include "TSLexia.h".
2. Dynamically load the libtslexia.so or TSLexia.dll library if needed.
3. Call CreateLexer() with the path to a Tree-sitter parser, e.g. CreateLexer("/path/to/libtree-sitter-c.so"). For multi-language files or for parsers that depend on others, use a ';'-separated list of paths, e.g. CreateLexer("libtree-sitter-c.so;libtree-sitter-cpp.so"). Make sure the order is from generic to specific or parent to child.
4. Use the returned lexer with Scintilla's SCI_SETILEXER message to set it.
5. Use Scintilla's SCI_SETKEYWORDS message to pass in a Tree-sitter query file that matches nodes and uses named captures for assigning styles to those nodes, e.g. SendScintilla(sci, SCI_SETKEYWORDS, 0, (sptr_t)"/path/to/tslexia/queries/c.scm"). When using multiple parsers, use the index of the parser passed to CreateLexer().
6. Define style settings for TSLexia's TSLEXIA_* styles (see TSLexia.h).
7. That's it!
