Generate ASCII art diagrams using PlantUML text mode. Use when user asks to create ASCII diagrams, text-based diagrams, terminal-friendly diagrams, or mentions plantuml ascii, text diagram, ascii art diagram. Supports: Converting PlantUML diagrams to ASCII art, Creating sequence diagrams, class diagrams, flowcharts in ASCII format, Generating Unicode-enhanced ASCII art with -utxt flag.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# PlantUML ASCII Art Diagram Generator

## Overview

Create text-based ASCII art diagrams using PlantUML. Perfect for documentation in terminal environments, README files, emails, or any scenario where graphical diagrams aren't suitable.

## What is PlantUML ASCII Art?

PlantUML can generate diagrams as plain text (ASCII art) instead of images. This is useful for:

- Terminal-based workflows
- Git commits/PRs without image support
- Documentation that needs to be version-controlled
- Environments where graphical tools aren't available

## Installation

```bash
# macOS
brew install plantuml

# Linux (varies by distro)
sudo apt-get install plantuml  # Ubuntu/Debian
sudo yum install plantuml      # RHEL/CentOS

# Or download JAR directly
wget https://github.com/plantuml/plantuml/releases/download/v1.2024.0/plantuml-1.2024.0.jar
```

## Output Formats

| Flag    | Format        | Description                          |
| ------- | ------------- | ------------------------------------ |
| `-txt`  | ASCII         | Pure ASCII characters                |
| `-utxt` | Unicode ASCII | Enhanced with box-drawing characters |

## Basic Workflow

### 1. Create PlantUML Diagram File

```plantuml
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add marielynneblock/arcanum-artifex/plantuml-ascii@sha256:2352e18e426b91e2

The line at the top of this page pins the label git:20260710.ffb3400, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
