cli_readme_builder 1.1.0

A builder to automate the process of creating a README for Dart console applications

Overview

The goal of this package is to automate the process of creating a readme file for Dart console applications.

How it Works

This package generates a single file which contains --help output from every command in the application.

This builder works as follows:

1. Find the binary executable file in your package
2. Run the executable with the --help flag
3. Capture the output and parse it
4. For each top-level command, capture the --help output of that command and its sub-commands
5. Generate a file with the information gathered above

Usage

1. Add cli_readme_builder and build_runner to pubspec.yaml

   name: example_cli
   dev_dependencies:
     build_runner: ^1.0.0
     cli_readme_builder: ^1.0.0
   

2. Run a build

   > dart pub run build_runner build
   

3. README.g.md will be generated with content:

example_cli

Example CLI app

Usage

example_cli --help

Help output:

Customization

To change the path of the generated file, create a build.yaml in the root of your package. By changing the output option of this builder, the path can be customized:

targets:
  $default:
    builders:
      cli_readme_builder:
        options:
          output: my_output_file.md
