Convert iTerm2 "itermcolors" file to VSCode terminal color scheme

iterm-colors-to-vscode.js

/* Generate colors using: `plutil -convert json` in your terminal */
const col = [] // run your .itermcolors file through the above parser and replace the array with the output
      
function componentToHex(c) {
  const hex = c.toString(16)
  return hex.length === 1 ? `0${hex}` : hex
}

const mapping = {
  'terminal.background':'Background Color',
  'terminal.foreground':'Foreground Color',
  'terminalCursor.background':'Cursor Text Color',
  'terminalCursor.foreground':'Cursor Color',
  'terminal.ansiBlack':'Ansi 0 Color',
  'terminal.ansiBlue':'Ansi 4 Color',
  'terminal.ansiBrightBlack':'Ansi 8 Color',
  'terminal.ansiBrightBlue':'Ansi 12 Color',

Thanks for sharing this, Sam! I just adapted this script to take a json file as an argument and threw it up in a gist here: https://gist.github.com/experimatt/71c8145d72acc034123fcfba0213c317

@experimatt No problem, glad it was useful 😁

I'm on iTerm2 Build 3.4.8. I didn't fine the .itermcolors file. But I was able to generate vscode config with these steps:

1. In iTerm preferences on the Profiles section on Colors tab on the bottom left corner press Other Actions -> Save Profile as JSON.
2. Copy the content of the generated JSON file to this gist's con constant like this: con = [<the json file content>]
3. Run the rest of the gist.

Btw, for anyone else who comes across this — You can also convert the .itermcolors (which is plist XML format) to JSON with plutil -convert json if you don't want to install another random NPM package.

Thanks for this handy little script!

@ian-h-chamberlain Ah that's really handy, thanks for that!
