Cannot execute rubocop in WSL from Windows

The file name of rubocop in WSL is rubocop, same as Linux. However, when VSCode is installed in Windows, configuration.ts tries to use rubocop.bat. So that, the extension cannot find the executable rubocop in WSL from VSCode in Windows.

Error message my_path_to_rubocop_in_wsl/rubocop.bat is not executable

I need an additional configuration to use WSL. We can execute a file in WSL from Windows:

C:\> wsl my_path_to_rubocop_in_wsl/rubocop

I use a workaround with a .bat file that I can reference in the vscode settings:

@echo off
bash.exe -c "~/.rvm/gems/ruby-2.5.0/wrappers/rubocop %*"

(I use rvm inside WSL, but you should be able to adjust for your own environment) Inspired by https://hackernoon.com/wsl-hacks-making-atom-linters-work-with-windows-subsystem-for-linux-c86d42eaf09e

It works! My rubocop.bat looks like this. (I use rbenv.)

@echo off
wsl ~/.rbenv/shims/rubocop $^(echo '%*' ^| sed -e 's^|\\^|/^|g' -e 's^|\^([A-Za-z]\^)\:/\^(.*\^)^|/mnt/\L\1\E/\2^|g'^)

In the end, I needed to convert Windows path in args into WSL path.
