False positive "fro" in "to and fro"

[bobbens]

Would it be possible to have the "fro" in "to and fro" not detected as a misspelling?

[DimitriPapadopoulos]

It's already in the rare dictionary.

See #3651.

In the case of fro, to my understanding, it is only used in to and fro, but I'm not sure it's possible to have codespell convert fro->for in all cases, except when it is part of to and fro.

Coedspell splits into individual words and compares each word with dictionaries of words with common typos. That's all. It could be modified to handle groups of words, but I feel the few use cases are not worth the extra complexity.

Tools based on IA would be much more effective. I haven't heard of such open source spelling/grammar checkers. All the AI-based tools I know of are proprietary tools on the cloud.
