#rlsbl.lint.python_ast

Python linter using tree-sitter AST parsing to detect library boundary violations including forbidden imports and stdout/logging usage.

#_node_line

def _node_line(node)

Return 1-based line number for a tree-sitter node.

#_collect_all_imports

def _collect_all_imports(tree, filepath)

Walk AST and collect all imported top-level module names.

Returns a set of (package_name, file_path, line_number) tuples.

#_check_forbidden_imports

def _check_forbidden_imports(tree, filepath, config)

Walk AST for import_statement and import_from_statement nodes.

#child_by_field

def child_by_field(node, field_name)

Find the module name in an import_from_statement.

tree-sitter-python represents 'from foo import bar' with the module as a dotted_name or relative_import child before the 'import' keyword.

#_check_stdout

def _check_stdout(tree, filepath, config)

Detect print(), sys.stdout/stderr.write(), and logging.* calls.

#_check_entry_points

def _check_entry_points(project_path, config)

Check pyproject.toml for CLI entry point declarations.

#PythonAstLinter

Python linter using tree-sitter AST analysis.

#lint

def lint(self, project_path: str, config: LanguageLintConfig) -> list[LintResult]

#scan_imports

def scan_imports(self, project_path: str) -> set[tuple[str, str, int]]

Collect all imported top-level module names from Python files.

Returns a set of (package_name, file_path, line_number) tuples.
