termaid is an open source Python package designed to convert Mermaid diagram syntax into Unicode text art. The tool supports 18 types of Mermaid diagrams, including flowcharts, sequence diagrams, class diagrams, ER diagrams, state diagrams, block diagrams, git graphs, gantt charts, architecture diagrams, pie charts, treemaps, mindmaps, XY charts, user journeys, packet diagrams, timelines, kanban boards, and quadrant charts.
Users can run termaid directly via the command line using 'uvx termaid' or install it as a Python library with pip. Additionally, the tool is accessible in the browser through a web interface powered by Pyodide, enabling live rendering of Mermaid code without local installation. The browser-based version allows users to view pre-rendered examples or input their own Mermaid syntax to generate text-based diagrams on the fly. Output is optimized for display in monospace fonts, ensuring clarity and alignment in text environments.
Customization options include adjusting horizontal and vertical padding within node boxes, setting the gap between nodes, choosing between Unicode and ASCII box-drawing characters, and enabling rounded corners on edge turns. These settings allow users to tailor the appearance of diagrams to their specific requirements for readability or compactness.
