This code imports modules and functions from Core.js and uses them to import specific functions from other modules, such as selectAst and makeHandler. The code then uses these functions to create a handler for a function named load ckeditor and leaves some commented out code that appears to have been used for testing or logging purposes.

Cell 4

var importer = require('../Core')
var {selectAst} = importer.import("select code tree")
var {handler, makeHandler} = importer.import("generic gcloud function handler")

//var testFunc = importer.interpret('load ckeditor')
//console.log(handler.toString())
//var doc = selectAst('.', handler.toString())
//console.log(assignmentStmt[0].ownerDocument.toString(assignmentStmt[0]))
makeHandler('load ckeditor')

// Import the required modules
const { importer } = require('../Core');
const { 
  selectAst, 
  makeHandler, 
  createFunctionHandler 
} = importer.import({
 'select code tree': true,
  'generic gcloud function handler': {
    handler: true,
    makeHandler: true
  }
});

// Function to load CKEditor
const loadCKEditor = async () => {
  try {
    // Create a handler for the function
    const ckeditorHandler = await makeHandler('load ckeditor');
    
    // Select the abstract syntax tree for the handler
    const ast = await selectAst('.', ckeditorHandler.toString());
    
    // TODO: Log the result
    //console.log(ast);
  } catch (error) {
    // Log any errors that occur
    //console.log(error);
  }
};

// Call the function
loadCKEditor();

Code Breakdown

Importing Modules

var importer = require('../Core')

• This line imports a module from a file named Core.js located in a parent directory.

Importing Specific Functions

var {selectAst} = importer.import('select code tree')
var {handler, makeHandler} = importer.import('generic gcloud function handler')

• These lines import specific functions from the imported importer module.
• selectAst is a function from the select code tree module imported by the importer module.
• handler and makeHandler are functions from the generic gcloud function handler module imported by the importer module.

Unused Function Calls

//var testFunc = importer.interpret('load ckeditor')
//console.log(handler.toString())
//var doc = selectAst('.', handler.toString())
//console.log(assignmentStmt[0].ownerDocument.toString(assignmentStmt[0]))

• These lines contain commented out code that were likely used for testing purposes.
• importer.interpret('load ckeditor') is a function call that is commented out.
• The following lines are commented out and appear to be related to logging and manipulating the abstract syntax tree (AST) of a code string.

Creating a Handler

makeHandler('load ckeditor')

• This line creates a handler for a function named load ckeditor using the makeHandler function imported earlier.
