This code imports a module named Core to use its importer function, which imports another module named search notebooks using gulp to search for notebooks. The search result is then processed asynchronously, formatted as markdown, and sent to the user, with error handling if the search fails.

Cell 6

var importer = require('../Core');
var searchNotebooks = importer.import("search notebooks using gulp");
var searchRegexp = 'permissions';

$.async();
searchNotebooks(searchRegexp)
    .then(r => $.mime({'text/markdown': '```\n' + r.map(c => c.code).join('') + '\n```\n-------------\n'}))
    .catch(e => $.sendError(e));

const { Core } = require('../Core'); // Import Core module and assign it an alias for clarity

const { searchNotebooks } = Core.import('search notebooks using gulp'); // Destructure the imported function for better readability

const searchRegexp = 'permissions'; // Define the search regex as a constant for easier modification and reusability

// Use async/await syntax for better readability and error handling
async function searchNotebooksAsync() {
  try {
    // Use the searchNotebooks function to retrieve the search results
    const results = await searchNotebooks(searchRegexp);
    
    // Process the results and display them in markdown format
    const markdown = results.map(c => c.code).join('\n') + '\n\n-------------\n';
    $.mime({'text/markdown': `# Search Results\n\n${markdown}`});
  } catch (error) {
    // Catch and display any errors that occur during the search or processing
    $.sendError(error);
  }
}

searchNotebooksAsync(); // Call the async function to start the search

Code Breakdown

Importing Modules

var importer = require('../Core');
var searchNotebooks = importer.import('search notebooks using gulp');

• The code imports a module named Core into the current scope.
• The importer module is then used to import another module named search notebooks using gulp, which is assigned to the searchNotebooks variable.

Searching Notebooks

var searchRegexp = 'permissions';
$.async();
searchNotebooks(searchRegexp)
   .then(r => $.mime({'text/markdown': '```\n' + r.map(c => c.code).join('') + '\n```\n-------------\n'}))
   .catch(e => $.sendError(e));

• A string permissions is assigned to the searchRegexp variable.
• The $.async() function is called, which is likely used to begin an asynchronous operation.
• The searchNotebooks function is called with the searchRegexp variable as an argument.
  • If the function call is successful, the then method is executed.
    • The r variable represents the result of the function call.
    • The $.mime() function is called with an object containing a text/markdown key and a value that represents the result in markdown format.
  • If the function call fails, the catch method is executed.
    • The $.sendError() function is called with the error object as an argument to handle the error.
