md-template

Build markdown from es6-templates and js

All js files will be executed and exported object will be deeply merged together in order. This data will be made available to the template.

Example

md-template ./template.md ./data.js > README.md

CLI

module.exports = () => {
  const { execSync } = require("child_process");
  const fs = require("fs");
  const path = require("path");
  const os = require("os");
  const uuid = require("uuid/v1");

  const expected = `
    # one
    1

    ## two
    2

    ## RGB
    red green blue
  `;

  const template = `
    # one
    \${one}

    ## two
    \${two}

    ## RGB
    \${color_channels.slice(0,3).join(" ")}
  `; // NOTE: backslashes not neccissary in actual file

  const data = `
    module.exports = {
      one: 1,
      two: 2,
      color_channels: ["red", "green", "blue", "alpha"]
    };
  `;
  const demoDir = path.join(os.tmpdir(), uuid());
  fs.mkdirSync(demoDir);
  const templatePath = path.join(demoDir, "template.md");
  const dataPath = path.join(demoDir, "data.js");

  fs.writeFileSync(templatePath, template);
  fs.writeFileSync(dataPath, data);

  const result = execSync(`node cli.js ${templatePath} ${dataPath}`, {
    encoding: "utf8"
  });
  return result === expected;
};

Usage

md-template:
  type: object
  example: md-template <TEMPLATE> <...DATA> [options]
  description: >
    Generates document from templated object and exported data.
    Prints new document to stdout
  properties:

      type: string
      example: template.md
      description: >
        Path to document whose text content will be used as
        a template string
    DATA:
      type: array
      description: >
        Paths to json files which will be required,
        properties exported by these scripts will
        be deeply merged in the order in the command
        and made available to template
      items:
        type: string
        example: data.js
    options:
      type: object
      properties:
        "-h":
