Pretty-prints a given string of `code`. Convenience method for debugging.

Cancel all pending tasks on `loop`, wait for them, and close the loop.

Nodeless stack copy.

Simple visitor generating strings to compare ASTs by content.

Strip minor versions for some specifiers in the specifier set. For background on version specifiers, see PEP 440: https://peps.python.org/pep

Replace `regex` with `replacement` twice on `original`. This is used by string normalization to perform replaces on overlapping matches.

The tokenize() function accepts two parameters: one representing the input stream, and one providing an output mechanism for tokenize().

Remove replacements from cell. For example "9b20" foo = bar becomes %%time foo = bar

Check that cell does not already contain TransformerManager transformations, or non-Python cell magics, which might cause tokenizer_rt to break be

If notebook is marked as non-Python, don't format it. All notebook metadata fields are optional, see https://nbformat.readthedocs.io/en/lates

Default `visit_*()` implementation. Recurses to children of `node`.

Return whitespace prefix if needed for the given `leaf`. `complex_subscript` signals whether the given leaf is part of a subscription which h

Return True if the line has leaves or comments.

StringTransformer instances have a call signature that mirrors that of the Transformer type. Raises: CannotTrans

Compare two nodes for equality. This calls the method _eq().

Initializer. Takes a type constant (a token number < 256), a string value, and an optional context keyword argument.

Initializer. Takes optional type, content, and name. The type, if given must be a token type (< 256). If not given, this m

Initializer. The argument is either a pattern or None. If it is None, this only matches an empty sequence (effectively '$'

Initializer. Creates an attribute for each grammar symbol (nonterminal), whose value is the symbol's type (an int >= 256).

Constructor that prevents BasePattern from being instantiated.

Return a canonical string representation.

Render the line.

Render a color report of the current state. Use `click.unstyle` to remove colors.

Return a pretty string representation. This reproduces the input source exactly.

Compare two nodes for equality.

Wraps calls to `right_hand_split`. The calls increasingly `omit` right-hand trailers (bracket pairs with content), meaning th

Match the pattern's content to the node's children. This assumes the node type matches and self.content is not None. Return
