Elixir bindings for tree-sitter-language-pack with on-demand parser downloads.
## Installation
```elixir
{:tree_sitter_language_pack, "~> 1.0"}
```
## Quick Start
```elixir
# Optional: Pre-download specific languages for offline use
TreeSitterLanguagePack.init(["python", "elixir", "javascript"])
# List all available languages
TreeSitterLanguagePack.available_languages()
# Check if a language exists
TreeSitterLanguagePack.has_language("python")
# Auto-downloads language if not cached
ptr = TreeSitterLanguagePack.get_language_ptr("python")
# Pre-download languages for offline use
TreeSitterLanguagePack.download(["python", "javascript"])
result = TreeSitterLanguagePack.process(source, ~s({"language":"elixir"}))
IO.inspect(result)
```
## API Reference
### Language Discovery
- `available_languages()` -- list all supported language names
- `has_language(name)` -- check if a language is available
- `language_count()` -- total number of supported languages
### Language Detection
- `detect_language(path)` -- detect language from file path
- `detect_language_from_extension(ext)` -- detect language from a bare file extension
- `detect_language_from_path(path)` -- detect language from a file path
- `detect_language_from_content(content)` -- detect language from shebang line
- `extension_ambiguity(ext)` -- check if an extension is ambiguous (returns assigned language + alternatives)
### Parsing
- `get_parser(name)` / `parse_string(source, language)` -- parse source code into a syntax tree
### Download API
- `init(languages)` -- pre-download specific languages for offline use
- `download(languages)` -- download parsers on demand
### Intelligence
- `process(source, config)` -- extract structured analysis (functions, classes, imports, comments, chunks) from source code
### Syntax Highlighting Queries
- `get_highlights_query(language)` -- get bundled highlights.scm query for a language
- `get_injections_query(language)` -- get bundled injections.scm query
- `get_locals_query(language)` -- get bundled locals.scm query
