The code is a Node.js module that generates a word cloud for a project. It uses the d3 library to convert a word cloud to SVG and the path module to work with file and directory paths.

Run example

npm run import -- "project word-cloud"

project word-cloud

var importer = require('../Core');
var path = require('path');
    
function projectWordCloud(project) {
    var d3CloudToSVG = importer.import("d3.ipynb[create word-cloud");
    var relativePaths = importer.import("relative paths and includes",
"{project}");
    
    var words = [];

    function wordCount(r) {
        var words = r['packages'].map(p => p.import)
            .concat(r['packages'].map(p => path.basename(p.file)))
            .concat(r['relatives'].map(r => path.basename(r.import)))
            .concat(r['relatives'].map(r => path.basename(r.file)));
        var wordCount = {};
        words.forEach(w => {
            if (typeof wordCount[w] === 'undefined') {
                wordCount[w] = 15;
            } else {
                wordCount[w]++;
            }
        });
        return Object.keys(wordCount).map((d) => ({text: d, size: wordCount[d]}));
    };

    return relativePaths(project)
        .then(words => d3CloudToSVG(wordCount(words)));

Code Breakdown

Requires and Function Definition

var importer = require('../Core');
var path = require('path');
    
function projectWordCloud(project) {
   ...
}

• The code starts by requiring two modules: ../Core and path. The path module is a Node.js built-in module for working with file and directory paths.
• The projectWordCloud function is defined, which takes a project parameter.

Module Imports

var d3CloudToSVG = importer.import('d3.ipynb[create word-cloud]');
var relativePaths = importer.import('relative paths and includes', {project});

• The importer module is used to import two modules: d3CloudToSVG and relativePaths.
• d3CloudToSVG is imported from d3.ipynb[create word-cloud]. This suggests that it's a function to convert a word cloud to SVG.
• relativePaths is imported from relative paths and includes with the project parameter. This suggests that it's a function to get relative paths and includes for a project.

Word Count Function

function wordCount(r) {
    var words = r['packages'].map(p => p.import)
           .concat(r['packages'].map(p => path.basename(p.file)))
           .concat(r['relatives'].map(r => path.basename(r.import)))
           .concat(r['relatives'].map(r => path.basename(r.file)));
    var wordCount = {};
    words.forEach(w => {
        if (typeof wordCount[w] === 'undefined') {
            wordCount[w] = 15;
        } else {
            wordCount[w]++;
        }
    });
    return Object.keys(wordCount).map((d) => ({text: d, size: wordCount[d]}));
};

• The wordCount function is defined, which takes an object r as a parameter.
• It maps over the packages and relatives properties of r, extracting the import and file names, and concatenates them into an array words.
• It initializes an empty object wordCount and iterates over words, incrementing the count for each word in wordCount.
• It returns an array of objects, where each object has a text property (the word) and a size property (the count).

Project Word Cloud Function

return relativePaths(project)
       .then(words => d3CloudToSVG(wordCount(words)));

• The projectWordCloud function returns a promise that:
• Calls relativePaths with the project parameter, which returns a promise that resolves to a value words.
• Calls wordCount with the words value, which returns a promise that resolves to an array of word cloud data.
• Calls d3CloudToSVG with the word cloud data, which returns a promise that resolves to an SVG string.

Module Exports and Execution

module.exports = projectWordCloud;

if(typeof $!== 'undefined') {
   ...
}

• The projectWordCloud function is exported as a module.
• The code checks if $ is defined, and if so, executes a block of code that:
• Defines a PROFILE_PATH variable based on environment variables.
• Defines a project variable based on the PROFILE_PATH.
• Calls projectWordCloud with the project variable, which returns a promise that is handled by $.async() and $.sendError().
