Use Neoformat for formatexpr #442
Description
I would like to do more or less the opposite of #36, i.e. use Neoformat as formatexpr, such that when I select some text and press gq it gets formatted as if I issued :Neoformat, but without a custom mapping.
I'd need a function to invoke, possibly passing parameters available to formatexpr:
The v:lnum variable holds the first line to be formatted.
The v:count variable holds the number of lines to be formatted.
The v:char variable holds the character that is going to be
inserted if the expression is being evaluated due to
automatic formatting. This can be empty. Don't insert
it yet!
I believe it should be possible just setting formatexpr in my configurations, but I'm not familiar with Neoformat internals, that's why I'm asking for help.

Hmm I think it's tricky because a lot of the underlying formatters don't support that sort of thing

But
:Neoformatis already able to format a visual selection. What is available to the command that would not be available while invoking throughformatexpr.For the time being, I just mapped
gQon:Neoformat(with the effect of shadowing Ex mode on Neovim), but now I have two formatters, and in most situations I'd only need a single one.iamFIREcracker commentedon Jan 11, 2023
@alecandido: you can give the following a try (I have been using it for months without much problem):
PS. to enable it, just run
setl formatexpr=NeoformatExpr()inside the filetype specific autogroup.alecandido commentedon Jan 11, 2023
Thanks, that is exactly what I had in mind (the concept, I was completely missing the implementation)
