ymlgen v0.1.4

ymlgen

A generator for YML/YAML files

Features

• Generate one or many files from YML/YAML config file
• Async rendering supported

Requirements

1. This extension only activates when YAML language is enabled
2. Create .ymlgen/generators directory that locates workspace root directory
3. Create first generator file in the generators directory, a generator file must be javascript file (.js)

4. The generator might look like this:

   const writeItem = ({ write, key, data }) => write(`<li>${key}:${data}</li>`);
   const writeSeparator = ({ write }) => write("<li>---</li>");
   
   // using nodejs export style
   module.exports = async (context) => {
     const { data, write } = context;
     write("Something");
   };

5. Create template file, a template file must be YML/YAML file

The template file must contain header, the header must follow the format below

# ymlgen: generatorName, *.fileExtension

Example: /yourWorkspaceDir/.ymlgen/generators/list.js

const writeItem = ({ write, key, data }) => write(`<li>${key}:${data}</li>`);
const writeSeparator = ({ write }) => write("<li>---</li>");

// using nodejs export style
module.exports = async (context) => {
  const {
    // write text to output file
    write,
    // helper
    $each,
    // the data is parsed from YML file
    data,
    // for fetching remote data purpose
    axios,
    // for schema validation purpose
    zod,
  } = context;

  // write string template
  await write()`<ul>`;
  await write(
    // data is array now, using $each helper to renders all data items
    $each(data, writeItem, { sep: writeSeparator })
  );
  // write simple value
  await write("</ul>");
};

/yourWorkspaceDir/test/list.yml

# ymlgen: list, *.html
- item1
- item2
- item3
- item4

After saving the yml file, ymlgen will create new file that locates in /yourWorkspaceDir/test/list.html

<ul>
  <li>0:item1</li>
  <li>---</li>
  <li>1:item2</li>
  <li>---</li>
  <li>2:item3</li>
  <li>---</li>
  <li>3:item4</li>
</ul>
