gvim netrw windows g:netrw_scp_cmd - transparent remote file editing does not work over scp

[j86989]

Hi,

I've finally found out that netrw replaces colon with slash in path to a temporary file and inserts slash at the beginning of the path. Consequently, the content of remote file cannot be copied to local temporary copy over scp on windors.

Path to temporary file (tmpfile) is modified here:

vim/runtime/autoload/netrw.vim

Lines 2101 to 2103 in 7f1664e

	if g:netrw_scp_cmd =~ '^scp' && (has("win32") || has("win95") || has("win64") || has("win16"))
	let tmpfile_get = substitute(tr(tmpfile, '\', '/'), '^\(\a\):[/\\]\(.*\)$', '/\1/\2', '')
	else

I have no idea when the path substitution helps but it may be really annoying when you use scp utility and its directory is added to PATH environmental variable.

let g:netrw_scp_cmd  = 'scpg3.exe -q' " Tectia Client

Workaround

It works when you undo substitutions in temporary file path.
Insert this line in autoload/netrw.vim file in if statement after substitution.

let tmpfile_get = tmpfile

but it's probably better to modify the condition in if statement...

Same issue here.

Reproducing:

1. Run :edit scp://host//linux_path
2. Vim will run scp /linux_path /windows_path
3. But windows path is substituted, which is something like /C/Users/me/AppData/Local/Temp/nonce.file

Another workaround is change:

vim/runtime/autoload/netrw.vim

Lines 2101 to 2103 in 7f1664e

	if g:netrw_scp_cmd =~ '^scp' && (has("win32") || has("win95") || has("win64") || has("win16"))
	let tmpfile_get = substitute(tr(tmpfile, '\', '/'), '^\(\a\):[/\\]\(.*\)$', '/\1/\2', '')
	else

To:

 if g:netrw_scp_cmd =~ '^scp' && (has("win32") || has("win95") || has("win64") || has("win16")) && !has("gui_running")
   let tmpfile_get = substitute(tr(tmpfile, '\', '/'), '^\(\a\):[/\\]\(.*\)$', '/\1/\2', '') 
 else

Encountered this exact issue on Windows using gVim, LKI's solution worked for me. Is there a way to solve this without editing autoload/netrw.vim? For example, is there a way to apply this hotfix from my user's vim configuration so I can put it under version control?
