Is it possible to get and edit the current filename with IDEAVim's VimScript?

[mbwgh]

I would like to write a short utility function which allows to jump quickly between files differing only in their file extension.
I.e. between .h and .c, or between .ts, and .html.

Maybe even something more general like jumping between between MyClass.java and MyClassDto.java or something.

I noticed however, that the % and # registers are not supported. I opened an issue for this, because I didn't not find one that addressed this. # is however supported as a special-case argument to :e.

Likewise, VimScript lacks functions like expand, or :h filename-modifiers like :t or :p.

So, is this (barely) possible in "IdeaVimScript", or is there some workaround, like using a different language or invoking Intellij commands something else?

I'd also like to know this. I'm trying to write a small vimscript function that runs different types of Rider formatting actions based on the filetype, along with some custom cleanup once it's finished. But I can't find any way to get the filetype or filename -- &ft and % seem to be missing in IdeaVim.

I'm using a workaround by abusing the clipboard like:

function! FilePath()
  let l:original_clipboard = @+
  exec 'action CopyPathFromRepositoryRootProvider'
  let l:file_path = @+
  let @+ = original_clipboard
  return file_path
endfunction

For other path action types:

1. Action menu > IdeaVim: Track Action IDs
2. Action menu > Copy Path/Reference

Side effect: status bar displays "... has been copied".
