Create separated json files

[esseti]

Hi,

Since I've already set up the Karabiner configuration, is it possible to use your script to create different JSON files for each "layer"? now it creates (and should overwrite) the standard karabiner file, which i don't really want to do.
Moreover, can it be used to assign hyper-command to open apps, hyper-opt for windows, and so forth, instead of using 'a' or 'w'?

for you first issue, you could prolly append your changes to your existing karabiner.json file with something like this.

const filePath = "path-to-karabiner.json";
let config;

if (fs.existsSync(filePath)) {
  // Read and parse existing file
  const fileContent = fs.readFileSync(filePath, "utf-8");
  config = JSON.parse(fileContent);

  // Ensure the structure is safe
  if (
    config.profiles &&
    Array.isArray(config.profiles) &&
    config.profiles[0]?.complex_modifications?.rules
  ) {
    // Append new rules
    config.profiles[0].complex_modifications.rules.push(...newRules);
  } else {
    // Fallback if structure is unexpected
    config = {
      global: {
        show_in_menu_bar: false,
      },
      profiles: [
        {
          name: "Default",
          complex_modifications: {
            rules: newRules,
          },
        },
      ],
    };
  }
} else {
  // File doesn't exist — create from scratch
  config = {
    global: {
      show_in_menu_bar: false,
    },
    profiles: [
      {
        name: "Default",
        complex_modifications: {
          rules: newRules,
        },
      },
    ],
  };
}

// Write updated or new config back
fs.writeFileSync(filePath, JSON.stringify(config, null, 2));
