Mermaid Cli

Mermaid-cli is a command line interface and programmatic tool that converts text-based diagram syntax into static visual assets. It functions as a headless browser renderer and markdown diagram processor, enabling the generation of diagrams through a CLI or a JavaScript-based generator.

The tool distinguishes itself by supporting the conversion of diagram definitions into multiple image formats, including SVG, PNG, and PDF. It allows for custom diagram styling by applying external CSS files to override default themes and add visual animations.

The project provides capabilities for markdown integration, where it scans files to replace diagram blocks with rendered images. It also supports automation workflows through standard input processing, allowing diagram definitions to be piped directly into the rendering engine.

Features

  • Text-to-Diagram Generators - Parses structured text syntax to automatically render visual diagrams in SVG, PNG, and PDF formats.
  • Diagram-to-Image Injection - Identifies diagram definitions within markdown files and replaces them with rendered SVG image references.
  • Diagram Renderers - Processes markdown files to find diagram blocks and replace them with rendered SVG images.
  • Data-Driven Diagram Generators - Provides a JavaScript-based generator to automate diagram creation from structured text within application workflows.
  • Diagram CLI Tools - Provides a command line interface to render Mermaid diagram definitions into SVG, PNG, and PDF files.
  • Diagram Renderers - Provides a programmatic API to transform text-based diagram definitions into visual graphical elements.
  • Image Format Conversion - Transforms diagram definitions into various image file types such as SVG, PNG, and PDF.
  • Multi-Format Image Exports - Converts browser-rendered SVG content into multiple formats including PNG and PDF.
  • Headless Rendering Engines - Utilizes a headless browser engine to execute rendering logic and capture visual snapshots of diagrams.
  • Document Automation Pipelines - Integrates diagram rendering into automated build pipelines to generate visuals from markdown and source code.
  • Diagram Block Injection - Scans markdown files to locate diagram blocks and replaces them with generated image paths.
  • Command Piping - Supports passing diagram definitions through shell pipes to generate images without intermediate files.
  • Standard Input Processing - Enables the processing of diagram definitions piped via stdin for command-line automation.
  • CSS Styling - Supports applying visual styles to generated SVGs using cascading stylesheet syntax.
  • Diagram Theme Overrides - Allows loading external stylesheets into the rendering environment to apply custom visual themes to diagrams.
  • Diagram Element Styling - Allows applying external CSS files to override default themes and add animations to diagram elements.

    Kroki is a text-to-diagram rendering API and diagram-as-code server that transforms plain text definitions from various modeling languages into SVG or PNG images. It functions as a multi-language diagram renderer, providing a unified interface to generate flowcharts, UML diagrams, and charts using a collection of external libraries. The system utilizes a container-based plugin architecture and a sidecar rendering model to isolate external rendering engines. This design allows for the addition of new diagramming languages via companion containers and ensures stateless image generation where so
