This code creates a dynamic web page that integrates web scraping, Git file access, and HTML manipulation, likely for web development or content management purposes.

Run example

npm run import -- "load ckeditor"

load ckeditor

var {URL} = require('url')
var importer = require('../Core')
var loadScraped = importer.import("get scraped page")
var getGist = importer.import("read gist files")
var {selectDom} = importer.import("select tree")
var applyAcl = importer.import("apply acl to html")
var gitFileTree = importer.import("git file tree")

// git 
async function gitEditor(url, gist, xpath) {
    // TODO: use a Github repo as the input
    if(typeof url == 'undefined') {
        url = 'https://google.com'
    }
    if(typeof url == 'string') {
        url = new URL(url);
    }
    var file = url.pathname
    var host = url.hostname.replace(/[^a-z0-9_-]/ig, '_')
    if(!file || file === '/') file = 'index'

    var files = await loadScraped(url)
    if(typeof files[ host + '-acl.json' ] === 'undefined') {
        var saved = (await getGist(gist)).files
        if(saved && saved[host + '-acl.json']) {
            files[host + '-acl.json'] = JSON.parse(saved[host + '-acl.json'].content || '[]')
        }
    }
    var doc = applyAcl((files[host + '-acl.json'] || []), files[file.replace(/[^a-z0-9_-]/ig, '_')])
    if(xpath) {
        console.log(decodeURIComponent(xpath))
        return selectDom([decodeURIComponent(xpath)], doc).map(el => el.outerHTML).join('')
    }
    
    var files = await gitFileTree()
    var fileDiv = doc.ownerDocument.createElement('div')
    fileDiv.className = 'initial-files file-tree'
    fileDiv.innerHTML = files
    doc.ownerDocument.body.appendChild(fileDiv)
    
    var codeDiv = doc.ownerDocument.createElement('div')
    codeDiv.className = 'initial-code code-editor'
    var codeText = doc.ownerDocument.createTextNode(importer.interpret('read crawl files').code);
    codeDiv.appendChild(codeText)
    doc.ownerDocument.body.appendChild(codeDiv)
    
    return '<!DOCTYPE html>\n' + doc.outerHTML
}

module.exports = gitEditor

if(typeof $ !== 'undefined') {
    $.async();
    gitEditor('https://www.google.com')
        .then(r => $.mime({'text/html': r}))
        .catch(e => $.sendError(e))
}

What the code could have been:

// Import dependencies
const { URL } = require('url');
const importer = require('../Core');
const { selectDom } = importer.import('select tree');
const applyAcl = importer.import('apply acl to html');
const getGist = importer.import('read gist files');
const loadScraped = importer.import('get scraped page');
const gitFileTree = importer.import('git file tree');

// Define the gitEditor function with async/await and more descriptive variable names
async function gitEditor({ url = 'https://google.com', gist, xpath } = {}) {
  // Ensure the URL is a URL object
  const parsedUrl = new URL(url);

  // Extract the file path and host from the URL
  const filePath = parsedUrl.pathname;
  const host = parsedUrl.hostname.replace(/[^a-z0-9_-]/ig, '_');
  const fileName = filePath === '/'? 'index' : filePath.replace(/[^a-z0-9_-]/ig, '_');

  // Load the scraped files and apply ACL if necessary
  const files = await loadScraped(parsedUrl);
  const aclFile = files[`${host}-acl.json`] || {};
  if (!aclFile.content) {
    const gistFiles = await getGist(gist);
    if (gistFiles && gistFiles.files[`${host}-acl.json`]) {
      aclFile.content = gistFiles.files[`${host}-acl.json`].content || '[]';
    }
  }

  // Apply ACL to the files and create an HTML document
  const doc = applyAcl(aclFile.content? JSON.parse(aclFile.content) : [], files[fileName]);

  // Select the DOM element if an XPath is provided
  if (xpath) {
    console.log(decodeURIComponent(xpath));
    return selectDom([decodeURIComponent(xpath)], doc).map(el => el.outerHTML).join('');
  }

  // Create the file tree and code editor elements
  const filesElement = doc.ownerDocument.createElement('div');
  filesElement.className = 'initial-files file-tree';
  filesElement.innerHTML = await gitFileTree();
  doc.ownerDocument.body.appendChild(filesElement);

  const codeElement = doc.ownerDocument.createElement('div');
  codeElement.className = 'initial-code code-editor';
  codeElement.appendChild(doc.ownerDocument.createTextNode(importer.interpret('read crawl files').code));
  doc.ownerDocument.body.appendChild(codeElement);

  // Return the HTML document as a string
  return '<!DOCTYPE html>\n' + doc.outerHTML;
}

// Export the gitEditor function
module.exports = gitEditor;

// Use the gitEditor function in a browser context if $ is defined
if (typeof $!== 'undefined') {
  $.async();
  gitEditor({ url: 'https://www.google.com' })
   .then(r => $.mime({ 'text/html': r }))
   .catch(e => $.sendError(e));
}

This code defines a function gitEditor that combines web scraping, Git interaction, and HTML manipulation to create a dynamic web page.

Here's a breakdown:

Overall Purpose:

This code creates a dynamic web page that combines scraped content, Git file information, and a code editor. It likely serves as a tool for web development or content management, allowing users to interact with web pages, Git repositories, and code snippets within a single interface.
