Dhruv Manilawala 7109214b57 Update parser tests to validate token ranges (#12019 ) ## Summary This PR updates the parser test infrastructure to validate the token ranges. From the code documentation: ``` /// Verifies that: /// * the ranges are strictly increasing when loop the tokens in insertion order /// * all ranges are within the length of the source code ``` Follow-up from #12016 and #12017 resolves: #11938 ## Test Plan Make sure that there are no failures.		2024-06-25 08:14:28 +00:00

Ruff Python Parser

Ruff's Python parser is a hand-written recursive descent parser which can parse Python source code into an Abstract Syntax Tree (AST). It also utilizes the Pratt parsing technique to parse expressions with different precedence.

Try out the parser in the playground.

Python version support

The parser supports the latest Python syntax, which is currently Python 3.12. It does not throw syntax errors if it encounters a syntax feature that is not supported by the target-version. This will be fixed in a future release (see https://github.com/astral-sh/ruff/issues/6591).
