If a path is written in form filepath:line (i.e. python exception), I want gf to jump straight to the line.

What you want already exists: :help gF.

Note that gF behaves like gf in the absence of a line number so you can default to gF if you don't want to think too much about which command to use in which case.

--- EDIT ---

Note that Python exceptions are actually in the form:

File "/path/to/file", line 10, in <module>

where the " and the , between the filename and line 1 trip Vim's algorithm. gF works fine for /path/to/filename:10 but not for every scenario.

  • Since : is part of ìsfname` on Windows (looks like a bug), to make it working you have to remove it first :set isfname-=: Dec 8, 2022 at 9:03

    This is not a bug, because you may have file paths with a drive letter Dec 8, 2022 at 11:05
  • Thanks @Christian but then the solution should include mention the setting change to meet the original requirement. Dec 8, 2022 at 14:52
  • @VivianDeSmedt, the suggestion of removing : from isfname is not a good idea, for the reason given by @ChristianBrabandt. It could be done temporarily in a wrapper but that's really not the spirit of this answer.

This is the implementation. I haven't completed it for vmap, though not complicated.

I didn't check it is really a line number, so be careful.

function! DoGF()
    let f=expand('<cfile>')
    let arr=split(f,':')
    if len(arr)>1
        if  filereadable(expandcmd(arr[0]))==0
            echoerr "File not exists"
            return
        endif
        :exe ':e '.arr[0]
        :exe ':'.arr[1]
    else
       norm! gf 
    endif
endfunction

nmap gf :call DoGF()<CR>
