Examples

The example/ directory contains runnable scripts that progress from simple output to full multi-command applications.

To run any example from the project root:

php example/01-hello-world.php

Example index

1. 01-hello-world.php Outputs a single message using command output helpers.

2. 02-greeter.php Accepts an optional named argument and prints a personalised greeting.

3. 03-colour.php Demonstrates one-off coloured output and persistent output palettes.

4. 04-parameters-and-flags.php Shows required named arguments, optional named arguments, required options and optional flags together.

5. 05-interactive.php Demonstrates interactive input with readLine() when optional arguments are omitted.

6. 06-multi-command.php Creates a multi-command CLI with sum, repeat, and built-in help.

7. 07-repeating-lines.php Demonstrates suppression markers for repeated consecutive output lines.

8. 08-progress-bar.php Shows an in-place progress bar that updates on one terminal line.

The examples are intentionally small and anonymous-class based so they can be copied directly into new scripts while keeping setup noise low.
