metalsmith-map-permalinks v1.0.0

metalsmith-map-permalinks :link:

A Metalsmith plugin to generate permalinks and paths for files and store a mapping from input files to paths.

This plugin will generate a permalink for all files that match its pattern using a list of formats. The formats are mustache strings and are evaluated first to last, so order matters. The values for the permalink fields are taken from the file metadata. Here's an example using the JavaScript API:

import map_permalinks from 'metalsmith-map-permalinks'

Metalsmith(__dirname)
  .source('src')
  .destination('dst')
  .use(map_permalinks({
    formats: [
      {
        pattern: 'posts/*.md',
        format: '{{date}}/{{title}}',
        date_format: 'yyyy',
      },
      {
        pattern: 'pages/*.md',
        format: '{{title}}',
      },
    ],
  }))
