you don't need to run this script,

unless you'd like to update the files here with the latest

version of VSCode.

usage:

1) install and open the latest VSCode

2) press Ctrl-Shift-P or Cmd-Shift-P to open 'quick start'

3) type 'Open Default Keyboard Shortcuts (JSON)' into the box and press Enter

4) copy and paste the resulting json file into

scripts/linux.keybindings.raw.json

scripts/windows.keybindings.raw.json

scripts/macos.keybindings.raw.json

, based on your OS

5) uncomment one of the lines like

processRawFile('linux.keybindings.raw.json')

at the bottom of this file

by removing the # and saving changes.

6) run this script, for example, in a terminal, run

cd scripts

python3 process_json.py

with any recent version of Python.

the script will replace/generate files like

linux.keybindings.json

linux.negative.keybindings.json

in the parent directory.
