SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Convert PlantUML diagrams into ASCII art so diagrams can be viewed in terminals, README Text, or environments without image support.

Core Features & Use Cases

Output ASCII art with -txt for standard ASCII or -utxt for Unicode-enhanced diagrams.
Support multiple diagram types (sequence, class, activity, deployment, use case, state, component).
Ideal for documentation, quick sharing in chat, and environments where graphical diagrams are impractical.

Quick Start

Create a PlantUML diagram file and run PlantUML with the -txt or -utxt flag to generate ASCII output.

FAQPage Schema

How do I convert PlantUML to ASCII art for terminal documentation?▼

To convert PlantUML to ASCII art for terminal documentation, you create a PlantUML diagram file and run PlantUML using the -txt flag for standard ASCII output or the -utxt flag for Unicode-enhanced diagrams.

Can I generate text diagrams for README files without image rendering support?▼

You can generate text diagrams for README files without image rendering support by converting PlantUML syntax into plain ASCII text or Unicode-enhanced ASCII, making diagrams viewable in environments where graphical images are impractical.

What diagram types are supported when converting PlantUML to ASCII text?▼

Converting PlantUML to ASCII text supports multiple diagram types, including sequence, class, activity, deployment, use case, state, and component diagrams for terminal-friendly visualization.

Does PlantUML ASCII output work for chat-based collaboration and terminal environments?▼

PlantUML ASCII output works for chat-based collaboration and terminal environments by producing plain text or Unicode-enhanced diagrams that can be viewed directly without graphical rendering capabilities.

What is the best way to share architecture diagrams in environments where images cannot be rendered?▼

The best way to share architecture diagrams where images cannot be rendered is generating ASCII text from PlantUML syntax, providing terminal-friendly visualization ideal for quick sharing in chat and text documentation.

Why use Unicode-enhanced ASCII output instead of standard ASCII text for diagrams?▼

Use Unicode-enhanced ASCII output instead of standard ASCII text when you need improved visual clarity in terminal diagrams, utilizing the -utxt flag to generate richer text-based visualizations than standard ASCII.
