language

✓ from tree_sitter_powershell import language

✗ from tree_sitter_powershell import Language

In v0.20+, the grammar exposes 'language' directly, not a Language class.

Parses a PowerShell snippet and prints the s-expression of the AST.

from tree_sitter import Language, Parser from tree_sitter_powershell import language PS_LANGUAGE = Language(language()) parser = Parser(PS_LANGUAGE) tree = parser.parse(b"Write-Host 'Hello, World!'") print(tree.root_node.sexp())

Debug

Known issues

gotchaThe grammar object is a callable that returns a language pointer. Use `language()` (not just `language`) when passing to `Language()` constructor.

fix

Use `Language(language())` instead of `Language(language)`.

affects: >=0.20.0

breakingIn version 0.20+, the import path changed: `from tree_sitter_powershell import language` replaces the old `from tree_sitter_powershell import Language` (where Language was a class).

fix

Update imports to `from tree_sitter_powershell import language`.

affects: >=0.20.0

deprecatedThe old `Language` class from tree-sitter-powershell <=0.19 is deprecated and may be removed.

fix

Upgrade to >=0.20.0 and use the new `language()` function.

affects: <=0.19

Errors

Common errors & fixes

TypeError: expected Language, got function

Passing the `language` function directly to `Language()` instead of calling it.

fix

Use `Language(language())`.

ImportError: cannot import name 'Language' from 'tree_sitter_powershell'

The `Language` class was removed in v0.20+.

fix

Use `from tree_sitter_powershell import language` and then `Language(language())`.
