Using a Windows GUI editor launched from WSL as git core.editor doesn't work

[kallja]

I'm running Microsoft Windows [Version 10.0.16299.192]

I've set up git editor under WSL with the following comand:
git config --global core.editor "'/mnt/c/Program Files/Sublime Text 3/subl.exe' -w"

I then cd myself into a local git repository in /mnt/c/Users/username/git/repo and run:
git rebase -i

Sublime Text 3 is launched, but WSL hands it a path argument it can't work with:
/mnt/c/Users/username/git/repo/.git/rebase-merge/git-rebase-todo
instead of the expected:
C:\Users\username\git\repo\.git\-rebase-merge\git-rebase-todo.

Is there a facility to translate paths in WSL to their Windows counterparts dynamically?

Yes, there is a tool called wslpath that should be available in your build. /bin/wslpath

wslpath usage:
    -a    force result to absolute path format
    -u    translate from a Windows path to a WSL path (default)
    -w    translate from a WSL path to a Windows path
    -m    translate from a WSL path to a Windows path, with ‘/’ instead of ‘\\’

    EX: wslpath ‘c:\users’

@benhillis I'm unclear on what are you suggesting here? I'm running into this as well and would love to understand what the workaround is

1. Create a shell script named wsl_git_editor.sh containing:

#!/bin/bash

WINDOWS_PATH=$(wslpath -w "$1")

"/mnt/c/Program Files/Sublime Text/subl.exe" -w "$WINDOWS_PATH"

2. Make the script executable with chmod +x wsl_git_editor.sh.
3. Add the script to your global config: git config --global core.editor <file-location>/wsl_git_editor.sh
