Python f Codec

Wrap lonesome f-strings in print().

How to install

> python3 -m pip install f-codec

Why?

Development

> python3 -m unittest test_fcodec -v # run the regression suite> uv build # build sdist and wheel into dist/

The test suite compares decoding against golden files in tests/golden/, which lock in the exact transformation of known-good sources.

TODO

• true streaming support for IncrementalDecoder (currently it buffers the whole input and decodes at once)
• skip f-string if the previous line ends with "" and it isn't a comment
• skip f-string inside another string
• support for ''' > indent on a single-line f-string (only whitespace or a comment may follow the closing quotes)
• support for triple-quoted strings inside an ''' > indent expression
• preserve CRLF line endings (currently normalized to LF)
