About plantuml-ascii
The plantuml-ascii skill allows users to generate text-based diagrams in ASCII format using PlantUML. This skill addresses the challenge of creating visually structured diagrams in environments where graphical rendering is not possible or practical, such as terminal interfaces, plain-text documentation, or version-controlled files. By converting standard PlantUML diagrams into ASCII or Unicode-enhanced ASCII art, it enables developers, technical writers, and documentation teams to include diagrams in contexts that traditionally do not support images.
Key features of this skill include support for a wide range of diagram types such as sequence diagrams, class diagrams, activity diagrams, state diagrams, component diagrams, use case diagrams, and deployment diagrams. Users can generate both standard ASCII output using the -txt flag and enhanced Unicode output with the -utxt flag. The skill also supports command-line usage through native PlantUML installations or directly via the JAR file, allowing flexibility in generating diagrams from individual files or entire directories. Output files are automatically saved in .atxt or .utxt formats for easy integration into terminal-based documentation workflows.
This skill is particularly useful for developers, DevOps engineers, and technical writers who need to produce documentation that is terminal-friendly or version-controlled without relying on graphical tools. Common use cases include embedding ASCII diagrams in README files, Git commit messages, email communications, or automated documentation pipelines. By providing a clear textual representation of system architectures, workflows, and interactions, plantuml-ascii ensures that complex diagrams are accessible in environments where images are impractical or unsupported.
FAQ
How do I generate an ASCII diagram from a PlantUML file?
You can use the command 'plantuml -txt diagram.puml' for standard ASCII output or 'plantuml -utxt diagram.puml' for Unicode-enhanced ASCII output. If using the JAR directly, use 'java -jar plantuml.jar -txt diagram.puml'.
What types of diagrams can I create with this skill?
The skill supports sequence diagrams, class diagrams, activity diagrams, state diagrams, component diagrams, use case diagrams, and deployment diagrams in ASCII or Unicode ASCII format.
Which operating systems are supported for installation?
PlantUML can be installed on macOS via Homebrew, on Linux via package managers like apt-get or yum, or by downloading the JAR file directly. The skill is compatible with environments where Java and PlantUML are supported.
Can I generate diagrams from multiple files or directories?
Yes, you can process all PlantUML files in a directory by running 'plantuml -txt ./diagrams/' or specify an output directory with the '-o' flag.
Are there any limitations compared to graphical diagrams?
ASCII diagrams are limited to textual representation and may not capture all visual styling available in graphical diagrams. Unicode-enhanced ASCII improves readability but is still text-based.
