Possiblity to ignore certain lines #38

Open Thaodan opened 10 months ago

Thaodan commented 10 months ago

Some modes post content in the buffer that is read-only and not related to the actual content that the user writes.

For example in have or ERC/Circe the messages sent by other users or for Mastodon the same and the keybinds shown.

I don't have much experience with such modes. Any suggestions as to how this could be implemented? Is it safe to assume that read-only content should always be ignored?

What about a regex? E.g. ignore everything after ^#.*

I'd assume so?

I don't think it's that simple. Content after # is not necessarily read-only and should not generally be ignored. In Python, for instance, I'd want to do the opposite: ignore everything that does not follow # because we would like to do language guessing based on the comments, not based on the code.

Having the ability to set this per buffer and thous per mode would help enough at first.

I'd be fine if read-only content can be ignored. Since depending on the mode the read-only content might indicate the buffer language e.g. the prior messages inside a chat mode.

Tbh, this sounds like a difficult-to-implement feature and it would have to be implemented for different modes separately.

Alternative proposal: How about a way to guess the language only based on the current paragraph, not the entire buffer? Wouldn't this also solve your use case?

That's why I think a pattern that should be ignore is the simplest solution. The user can set a pattern per mode for themselves.

While read-only content could be ignored if so choosen e.g. global or per make-local-variable.

I won't have time to work on this myself, but feel free to sketch an PR.
