Groovy grammar for tree-sitter, version 0.1.2. Provides a parser and syntax tree for Groovy files. Low release cadence; mature grammar.

pip install tree-sitter-groovy

Common errors

error ModuleNotFoundError: No module named 'tree_sitter_groovy' ↓

cause tree-sitter-groovy not installed or installed in a different environment.

fix

Run pip install tree-sitter-groovy in the correct environment.

error TypeError: language() takes 0 positional arguments but 1 was given ↓

cause Passing arguments to `language()` which is no longer supported.

fix

Call language() with no arguments; it returns the language object directly.

Warnings

gotcha The grammar is incomplete and may fail on complex Groovy constructs. ↓

fix Test thoroughly; consider contributing to grammar improvements.

deprecated The old API of directly calling `language` without importing from the specific package is deprecated. ↓

fix Use `from tree_sitter_groovy import language` instead of `import tree_sitter_groovy; tree_sitter_groovy.language()`.

Imports

language

wrong

import tree_sitter_groovy; tree_sitter_groovy.language()

correct

from tree_sitter_groovy import language

Direct import of the function avoids namespace confusion

Quickstart

Parse a Groovy snippet and print the syntax tree.

from tree_sitter import Language, Parser
from tree_sitter_groovy import language

Lang = Language(language())
parser = Parser()
parser.set_language(Lang)

tree = parser.parse(b'println "hello"')
root = tree.root_node
print(root.sexp())
