Cygwin Git + VS Code compatibility

Thanks and credit to mattn and ferreus on GitHub.

cygpath-git-editor.sh

#!/bin/bash

# wrapper to convert linux paths to windows
# so vscode will work as a git editor with cygwin
# editor="/home/this/file.sh" in .gitconfig

# extract last argument (the file path)
for last; do true; done

# get all the initial command arguments
all="${@:1:$(($#-1))}"

# launch editor with windows path
code $all $(cygpath -w $last)

cygpath-git-vscode.bat

@echo off

REM wrapper to convert linux paths to windows
REM so vscode git integration will work with cygwin
REM "git.path"="C:\\this\\file.bat" in settings.json

setlocal
set PATH=C:\cygwin\bin;%PATH%

if "%1" equ "rev-parse" goto rev_parse
git %*
goto :eof
:rev_parse
for /f %%1 in ('git %*') do cygpath -w %%1

Emmm...There may be still a small problom for me. In this way, it's display file status correctly. But when using the source manage in the VSCode Sidebar, it doesn't work. It still prompt "can't spawn git.bat". So sad :(

I tried the bat wrapper, it worked for basic git status display, but trying to stage/unstage a file resulted in errors.

I.e. either of these commands issued by VS Code failed:
Stage: git add -A -- C:\project\hxcalc\package.json
Unstage: git reset -q HEAD -- C:\project\hxcalc\package.json
Both of them result result in fatal: C:\project\hxcalc\package.json: 'C:\project\hxcalc\package.json' is outside repository at '/mnt/c/project/hxcalc'

I tried the same commands in Cygwin bash, and indeed, Cygwin git doesn't seem to be able to handle Windows paths.

What worked for me is this: github.com/nukata/cyg-git. It's a tiny C wrapper that you compile with gcc (for my use case, regular Cygwin gcc worked), and a Zsh wrapper script that works similar to cygpath-git-vscode.bat, but it also takes care of converting paths passed to git. I had to make a small change to this script to make it handle rev-parse commands that produce multiple lines of output (made a PR to the original repo).
