The CLI Code Generator is a command-line interface (CLI) application designed to generate code based on templates provided in JSON format. It accepts a JSON configuration file and uses the Go standard library as a templating engine to generate code files.

The CLI Code Generator requires a JSON configuration file specifying the templates, destination paths, variables, and file renames. Here's how to use it:

./cgen -c <config_file.json>

Or using the long option:

./cgen --config <config_file.json>

If no configuration file is provided, the CLI Code Generator will look for a file named .gen.config.json in the current working directory.

{
  "templates": {
    "path": "templates",
    "destination": "src",
    "variables": [
      {
        "name": "Name",
        "value": "John"
      },
      {
        "name": "ShowDetails",
        "value": "true"
      },
      {
        "name": "Age",
        "value": "30"
      },
      {
        "name": "Location",
        "value": "New York"
      }
    ],
    "fileRenames": [
      {
        "from": "_demo",
        "to": "Demo"
      }
    ]
  }
}

• templates: Object specifying the path to the templates directory, destination directory for generated code, variables to be substituted in templates, and file renaming rules.
  • path: Path to the directory containing template files.
  • destination: Path to the directory where generated code files will be saved.
  • variables: Array of objects specifying variable names and their values for substitution in templates.
  • fileRenames: Array of objects specifying rules for renaming files during generation.

The CLI Code Generator uses the Go standard library as a templating engine. Templates follow the Go text/template package syntax. Learn more about Go templates here.
