Compile with:

gcc -framework Carbon -o resizer resizer.c

Create hotkey mapping and call the resizer CLI with params:

{
  "from": {
    "key_code": "1",
    "modifiers": {
      "mandatory": [
        "left_option"
      ]
    }
  },
  "to": [
    {
      "shell_command": "/Users/****/scripts/resizer .95 .95"
    }
  ],
  "type": "basic"
}

Execute with:

resizer .85 .85

Param1 - would be horizontal ratio and Param2 - would be vertical ratio

Remember to activate access in Settings->Accessibility for the CLI resizer, Terminal, Karabinier shell

Tested on:

-Catalina 10.15.7
-Monterey 12.1

Current issues:

• when connected to multiple monitors, will take the current window but it will be moved to the primary monitor, as a solution it should be taken the current active/focused display on:

  //getting display sizes
  auto mainDisplayId = CGDirectDisplayID();
