Concept

gleichzeitig starts all commands specified in its configuration and keeps them running until they terminate. It redirects all stdout and stderr to its own output and throws errors if a process terminates prematurely or with a non 0 exit code.

Configuration

To keep the gleichzeitig setup low friction, the gleichzeitig init command creates the configuration directory and the config.json file with the default configuration in it.

The configuration is located at .gleichzeitig/config.json in the current working directory and is composed of the following key value pairs:

{
  "only_color_prefix": true,
  "color_output": true,
  "commands": [],
  "log_file": "",
  "surpress_output": false
}

• only_color_prefix: wheter to color the full stdout and stderr prints or only the prefixes: 0x |
• color_output: whether the output of the individual commands should be coloured different to allow the user to differentiate between them
• commands: array of instructions gleichzeitig executes, of the following format:

  {
    "cwd": ".gleichzeitig",
    "cmd": "echo 'test'"
  }

  • cwd: specify the working directory for the command to execute in, supports relative paths
  • cmd: the command to execute, if not found error is thrown
• log_file: the file to write all logs to
• surpress_output: whether the commands stdout and stderr should be printed
