FAQPage Schema

How do I convert PlantUML to ASCII art for a plain text README?▼

To convert PlantUML to ASCII art, you provide the PlantUML definitions to the tool, which generates text-based diagrams using standard ASCII or Unicode box-drawing characters suitable for any plain text environment.

What types of diagrams can I render as text-based ASCII?▼

You can render sequence, class, activity, state, component, use case, and deployment diagrams as text-based ASCII art directly from standard PlantUML code definitions.

Do I need the PlantUML executable to generate ASCII diagrams?▼

Yes, generating ASCII diagrams requires the PlantUML executable or JAR file installed, as the tool relies on these command-line processors to parse and render the text-based output.

Can I use Unicode box-drawing characters instead of standard ASCII for diagrams?▼

Yes, the tool supports generating diagrams using either standard ASCII characters or enhanced Unicode box-drawing characters, allowing you to choose the text format that best fits your terminal display.

Why generate sequence diagrams as ASCII art instead of images?▼

Generating sequence diagrams as ASCII art ensures they render correctly in environments that do not support graphical images, such as command-line terminals, plain text documentation, or standard text editors.
