[Data Liberation] Use WordPress for editing static files in a local directory

[adamziel]

Exploring a WordPress plugin that can import a tree of static files as WordPress posts and store any database updates back as static files on the disk.

<?php

require_once __DIR__ . '/../../bootstrap.php';
require_once __DIR__ . '/../../../data-liberation-markdown/src/bootstrap.php';

use WordPress\Zip\WP_Zip_Filesystem;
use WordPress\ByteReader\WP_File_Reader;
use WordPress\ByteReader\WP_Remote_File_Ranged_Reader;


$fs = new WP_Zip_Filesystem(
    WP_File_Reader::create(__DIR__.'/../docs.zip')
);


$hierarchy = WP_Filesystem_To_Post_Hierarchy::create(
    $fs,
    array (
        'root_dir' => '/',
        'first_post_id' => 2,
        'filter_pattern' => '#\.md$#',
        'index_file_pattern' => '#^index\.md$#',
    )
);

while($hierarchy->next_post()) {
    $post = $hierarchy->get_current_post();
    if($post['type'] !== 'file') {
        continue;
    }
    
    $converter = new WP_Markdown_To_Blocks( $fs->read_file($post['source_path']) );
    if( false === $converter->convert() ) {
        throw new Exception('Failed to convert Markdown to blocks');
    }
    $entities = new WP_Block_Markup_Entity_Reader(
        $converter->get_block_markup(),
        $converter->get_all_metadata(),
        $post['post_id']
    );
    while($entities->next_entity()) {
        // foreach($entities as $entity) {
        $entity = $entities->get_entity();
        $data = $entity->get_data();
        if( $entity->get_type() === 'post' ) {
            $data['id'] = $post['post_id'];
            $data['guid'] = $post['source_path'];
            $data['post_parent'] = $post['post_parent'];

            $data['post_title'] = $data['post_title'] ?? null;
            if ( ! $data['post_title'] ) {
                $data['post_title'] = WP_Import_Utils::slug_to_title( basename( $post['source_path'] ) );
            }

            var_dump($data);
        }
    }
}

I'll close this intermediate stacked PR and split the larger work in #2109 into smaller chunks
