Hi everyone, I am very excited to share with you a PEP that Batuhan Taskaya, Lysandros Nikolaou and myself have been working on recently: PEP 701 - PEP 701 – Syntactic formalization of f-strings <https://peps.python.org/pep-0701/>.
We believe this will be a great improvement in both the maintainability of CPython and the usability of f-strings. We look forward to hearing what you think about this and to get your feedback! *Here is a TLDR for your convenience:* - The PEP proposes a formalized grammar for f-strings in Python by adding f-strings directly into the Grammar instead of using a two-pass hand-written parser. - This would lift some existing restrictions for f-strings that (we believe) will improve the user experience with f-strings. - Other benefits include: - Reduced maintenance costs for f-string parsing code as well as improved usability for users and library developers. - Better error messages involving f-strings by leveraging the PEG parser machinery. - The proposed changes would improve the overall consistency of the language and provide a way for alternative implementations to accurately implement f-strings. *** IMPORTANT: direct all discussions to the discussion thread on discourse: https://discuss.python.org/t/pep-701-syntactic-formalization-of-f-strings/22046 <https://discuss.python.org/t/pep-701-syntactic-formalization-of-f-strings/22046> *** Thanks a lot, everyone for your time! Regards from rainy London, Pablo Galindo Salgado
