more flexible goto_file

[ModProg]

After opening #8822 I noticed that there are more things I miss from vim in regard to gf.

1. Allow non . punctuation after a path, e.g., path, or "path"; should open path and not path, and path"; respectively, if you want the latter behavior it is easy enough to just do a f,gf. (maybe we could have a config option for what characters are path, like isfname in VIM)
2. Support paths that omit the file extension. Simple behavior could be “if file not exist, try appending current extension”, but a more flexible tool could be a file type based suffixesadd (VIM) like list of extensions to try.
3. VIM also as a includeexpr which allows transforming a path by replacing characters, i.e., . with / in java imports. (This is applied after the normal behavior failed.) This might be best implemented when the scripting support lands, though we could also just have a regex, replacements tuple that would probably already cover most things.

Not every file has an LSP, and this just allows navigating these almost as if one had one.

I feel like at least 1. is very actionable, and I'd look into implementing this and #8822.

If you agree with the other additions, I'd look into those as well, though I'd need some input on how the config options should look.

I am unsure about the direction of VIM about such this feature but can we instead have file picker show up with the relevant text in search box?

Until it is implemented is there a way to map a new keyboard shortcut to search for file using file picker with selected text under cursor?

Personally, I feel like points 2. and 3. would be better left for plugin (once that's possible). Point 1. seems like a reasonable requirement that would ideally be fixed.

for anyone who subscribed to this: Could you try out #9065 pls? gf should now basically behave similar to gf in neovim.
