Remark Simple PlantUML Plugin with local Rendering

@felixpaq/remark-local-plantuml is a simple plugin for remarkjs that converts PlantUML code locally to inline html SVG nodes.

Forked for these reasons :

• Needed to update to node-plantuml-back
• Adding collapsible block with plantuml source in it

• Update packages to latest versions

Won't be maintained in the future unless I need to.

Installing

npm install --save @mstroppel/remark-local-plantuml

Example

You can use this plugin like following

Markdown

# Your markdown including PlantUML code block

```plantuml Your title
class SimplePlantUMLPlugin {
    + transform(syntaxTree: AST): AST
}
```

JavaScript

const remark = require("remark");
const simplePlantUML = require("@mstroppel/remark-local-plantuml");
const fs = require("fs");
const path = require("path");

const input = fs.readFileSync(path.resolve(__dirname, "./your-markdown.md")).toString();
const output = remark().use(simplePlantUML).processSync(input).toString();

console.log(output);

Integration

You can use this plugin in any frameworks that support remarkjs.

If you want to use in the classic preset of Docusaurus 2 or 3, set configuration in your Docusaurus.config.js like following:

const simplePlantUML = require("@mstroppel/remark-local-plantuml");

// your configurations...

presets: [
    [
      "@docusaurus/preset-classic",
      {
        docs: {
          sidebarPath: require.resolve("./sidebars.js"),
          remarkPlugins: [simplePlantUML]
        }
      }
    ]
  ],

//...

Issues

Issues Using Docusaurus 3

when on npm run start or npm run build of Docusaurus the following error appears:

Error: MDX compilation failed for file "C:\data\source\tapio.InternalDocs\docs\context.md"
Cause: Cannot handle unknown node `raw`
Details:
Error: Cannot handle unknown node `raw`

Use the rehype-raw as rehypeplugin in Docusaurus.

Install rehype-raw:

npm install rehype-raw

Add the following to the top of docusaurus.config.js file: and add the MDX plugin in next to the remark-local-plantuml plugin:

const localPlantUML = require("@mstroppel/remark-local-plantuml");
import rehypeRaw from 'rehype-raw';
const rehypeRawOptions = {
  passThrough: ['mdxjsEsm']
};

// your configurations...

presets: [
    [
      "@Docusaurus/preset-classic",
      {
        docs: {
          sidebarPath: require.resolve("./sidebars.js"),
          remarkPlugins: [localPlantUML],
          rehypePlugins: [[rehypeRaw, rehypeRawOptions]],
        }
      }
    ]
  ],
