markdown-it-conditional-render

English | 中文

Markdown It conditional rendering plugin, inspired by markdown-it-condition, the original repository has been removed or moved, but the compiled and compressed code is still available in NPM and has been extracted from lib/markdown-it-condition.js.

Demo

Options

• ruleName：string
  • Default: condition
  • Custom rule name
• ifMarker：string
  • Default: ::if
  • Judging from here, if branching condition
• elseIfMarker：string
  • Default: ::elseif
  • else if branching condition
• elseMarker：string
  • Default: ::else
  • else branching condition
• endIfMarker：string
  • Default: ::endif
  • End of judgment
• validate(condition: string): boolean
  • Preprocess the original text and verify the branching conditions in the text
  • Default returns true
• evaluate(condition: string, value: any): boolean

  • Parse the actual parameters and remove the text that does not meet the conditions

  • The default processing is as follows：

    function evaluate(condition: string, value: any) {
        let element = value;
        condition.split(".").forEach((field) => {
            element = element[field];
        });
    
        if (!!element) {
            return true;
        }
    
        return false;
    }

The full usage of each parameter by default is shown in the example

Example

const MarkdownIt = require("markdown-it")
const markdownItEngine = new MarkdownIt();
const markdownItConditionalRender = require("markdown-it-conditional-render");

markdownItEngine.use(markdownItConditionalRender);

const res = markdownItEngine.render(
  `
::if flag.value

*This text will be shown*

::else

*This text won't

::endif
`,
{
  flag: {
    value: true,
  },
});

console.log(res);
