Gulp-eslint throws errors on dynamically loaded JSs - gulp-eslint

I have a project structure like
There are approx 10 JS files in com. lab1 and lab2 has a config.json file which tells, out of 10 files which files to be concatenated and placed as app-min.js in dist/lab1 or dist/lab2.
In the gulp file I've created something like this.
var filesArr = [];
var labName;
// Player Task
gulp.task('player', function () {
return gulp.src(filesArr)
compress: {
drop_console: true
}).on('error', gutil.log))
.pipe(gulp.dest('dist/' + labName));
// Clean
gulp.task('clean', function () {
if (readJson()) {
return del([
'dist/' + labName
return null;
// Watch
gulp.task('watch', function () {, gulp.series('player'));
// Read Json and create JS Array
function readJson() {
var _n = prompt('Specify the LAB name. ');
labName = _n;
var _path = path.resolve('./src/' + _n);
var _exists = fs.existsSync(_path);
if (_exists) {
var _json = fs.readFileSync(path.resolve(_path + '/labstructure.json'), 'utf-8');
var _jObj = JSON.parse(_json).labObj.components;
for (var i = 0; i < _jObj.length; i++) {
var _jsName = 'src/com/component/' + _jObj[i].ref + '.js';
if (filesArr.indexOf(_jsName) === -1) {
return _exists;
gulp.task('default', gulp.series('clean', 'player', 'watch'));
Here the filesArr looks like:
[ 'src/com/component/ColorActClass.js',
'src/kl1001_color/BrainClass.js' ]
This works perfectly fine at the first place. But when any JS is modified then in watch player task throws eslint error on some files which are untouched. This doesn't happen always rather if watch is running for 10-20 mins then it throws error. Like this:
In this case CheckBoxCompClass.js is not the file which is modified, but still got the issue. On top of that, the semicolon is in place. If this file has issue then eslint should have thrown the error at the first place.
Please help.

Accidentally, my NVM was set to an older version. Solved the issue after updating the NVM and by setting the current NVM version to the latest one.


vscode findFiles returns nothing but npm glob returns correct results

I'm writing and vscode extension in which I need a list of the test files inside workspace.
To find the test files I'm using the default testMatch from the jest.config.js which is:
My problem is that vscode.workspace.findFiles returns empty array and I cannot set it up to get correct results, but using Glob package the output is correct.
protected async findTestFiles(
matchTestsGlobPatterns: string[]
): Promise<vscode.Uri[]> {
const testFilesUris: vscode.Uri[] = [];
const glob_testFilesUris: vscode.Uri[] = [];
const { name: workspaceName, workspaceFolders } = vscode.workspace;
if (workspaceName === undefined || workspaceFolders === undefined) {
throw new Error(`No active workspace${!workspaceFolders ? ' folders' : ''}.`);
for (let folderIdx = 0; folderIdx < workspaceFolders.length; folderIdx++) {
const folder = workspaceFolders[folderIdx];
// - by vscode.workspace.findFiles
for (let patternIdx = 0; patternIdx < matchTestsGlobPatterns.length; patternIdx++) {
const currentPattern = matchTestsGlobPatterns[patternIdx];
const pattern = new vscode.RelativePattern(
const files = await vscode.workspace.findFiles(
console.log('by [vscode.workspace.findFiles]', testFilesUris.length);
// - by npm Glob
var glob = require('glob');
for (let patternIdx = 0; patternIdx < matchTestsGlobPatterns.length; patternIdx++) {
const currentPattern = matchTestsGlobPatterns[patternIdx];
const files: any[] = await new Promise((resolve, reject) => {
absolute: true,
cwd: folder.uri.fsPath,
ignore: ['**/node_modules/**']
function (err: Error, files: any[]) {
if (err) {
return reject(err);
console.log('by [npm Glob]', glob_testFilesUris.length);
// #todo: remove duplicates.
return testFilesUris;
The example console output of this function for some project is:
by [vscode.workspace.findFiles] 0
by [npm Glob] 45
Project structure:
So my question is how do I call vscode.workspace.findFiles to get correct results, or is there known problem with this function?
I have found some kind of answer to the question.
The problem is ?(x) in patterns. The vscode.workspace.findFiles does not work with this pattern as other packages do. If remove it from mentioned glob patterns they work except the .jsx | .tsx files are ommited.
After deep dive into vscode github's issues I have learned (here) that vscode.workspace.findFiles does not support extended patterns like ?(patterLike)

How to apply delay in JSZip API to load?

How to apply delay in JSZip API ? I want to zip multiple file. but I want to add some delay between transferring the files from webserver. How to add delay in below code?
This is for browser and deploying binaries inside the device.
$ = function () {
var urls = ["/FILES/AlertLog.txt",
function compress_files(urls) {
var zip = new JSZip();
var deferreds = [];
for (var i = 0; i < urls.length; i++) {
$timeout(function(){ deferreds.push(addToZip(zip, urls[i], i));
},200);// issue to deferreds variable =>undefined
$.when.apply(window, deferreds).done(generateZip);
function addToZip(zip, url, i) {
var deferred = $.Deferred();
JSZipUtils.getBinaryContent(url, function (err, data) {
if(err) {
else {
var arr=url.split("/");
zip.file(arr[2], data, { binary: true });
return deferred;
add some delay of milliseconds between transferring the files from the webserver.
I am trying to download the individual file by giving some delay. It fixed my problem
function downloadAll(files){
if(files.length == 0) return;
file = files.pop();
var theAnchor = $('<a />')
.attr('href', file[1])
// Firefox does not fires click if the link is outside
// the DOM
downloadAll(files); }
function downloadAll(files){
if(files.length == 0) return;
file = files.pop();
var theAnchor = $('<a />')
.attr('href', file[1])
// Firefox does not fires click if the link is outside
// the DOM
$('').on('click', function(){
['file1.csv', 'data:text/csv;charset=utf8,'+
['file2.txt', 'data:text/plain;charset=utf8,'+
encodeURIComponent('this script can do what I need.')],
['file3.js', 'data:text/javascriptcharset=utf8,'+
encodeURIComponent('alert(\'You can donate me your house if you like this script :-) \')')]

node.js loop through array to write files

I've been working through a few others, also this of looping through array to http.get data from a variety of sources. I understand that nodeJS is working asynchronously which is allowing the files to be written empty or with incomplete data, but I can't seem to get past this point.
Problem: calls are made, files are built but the files are always empty
Goal: loop through an array to create files locally from the sites data. Here is what I've got so far:
var file_url = '',
DOWNLOAD_DIR = './esri/',
esriAMD = [ '_coremap.js', 'arcgis/csv.js'];
function readFile(callback) {
if (esriAMD.length > 0) {
var setFile = esriAMD.shift(),
file_name = url.parse(file_url).pathname.split('/').pop(),
trial = setFile.split('/').pop(),
file = fs.createWriteStream(DOWNLOAD_DIR + trial);
http.get(file_url + esriAMD, function(res) {
res.on('data', function(data) {
console.log(setFile + ' has been written successfully');
res.on('end', function(){
console.log(setFile + ' written, moving on');
} else {
readFile(function() {
console.log("reading finishes");
Any insight would really help.
var esriAMD = [....];
function readFile(callback) {
http.get(file_url + esriAMD, function(res) {
concatenating strings with arrays may yield unexpected results.
you want to make sure that
you know what URLs your program is accessing
your program deals with error situations (where the fsck is res.on('error', ...)?)
Solution: I was passing the wrong variable into the http.get
Working code:
var file_url = 'http://.....',
DOWNLOAD_DIR = './location/';
esriAMD = ['one', 'two', 'three'..0;
function readFile(callback) {
if(esriAMD.length > 0) {
var setFile = esriAMD.shift(),
file_name = url.parse(setFile).pathname.split('/').pop(),
trial = setFile.split('/').pop(),
file = fs.createWriteStream(DOWNLOAD_DIR + trial);
http.get(file_url + setFile, function(res){
res.on('error', function(err){
res.on('data', function(data){
console.log(setFile + ' started');
res.on('end', function(){
console.log(setFile + ' completed, moving on');
} else {

Userscript breaking pages outside of domain

Even though I have my userscript restricted to one domain, any site I visit that uses Jquery experiences all kinds of nasty issues when my script is active. Checking the error console in chrome reveals an identical error on all sites:
"Uncaught TypeError: Property '$' of object [object Window]"
What's causing this? My objective is to get my userscript running in noconflict mode on a site that uses both jquery and prototype. I didn't make the code above var = myFunction, so I don't know what about it is causing the problem I'm running into. Any suggestions?
// ==UserScript==
// #name Restore Dashboard Tags
// #namespace
// #description This script restores a user's tracked tag list to the sidebar on tumblr
// #author
// #homepage
// #history 1.0 first version
// #include*
// #match*
// ==/UserScript==
var jQuery, $ = null;
function addJQuery(callback) {
var p = null;
if(window.opera || window.navigator.vendor.match(/Google/)) {
var div = document.createElement("div");
div.setAttribute("onclick", "return window;");
p = div.onclick();
else {
p = Window;
jQuery = $ = p.jQuery.noConflict();
var myFunction = function() {
jQuery('div#right_column ul:first-child').after('<ul class="controls_section" id="tracked_tags"></ul>');
jQuery('div.tracked_tags a').each(function (i) {
var tagID = jQuery(this).attr("id");
var tagIDNumber = tagID.replace('tag_','');
var tagName = jQuery(this).attr("href");
var tagNameClean = tagName.replace('/tagged/','');
var tagContent ='';
tagContent += '<li><a href="'+tagName+'" id="'+tagID+'" class="tag">';
tagContent += '<div class="hide_overflow">'+tagNameClean+'</div>';
tagContent += '<span id="tag_unread_'+tagIDNumber+'" class="count" style=""></span></a></li>';
jQuery(tagContent).appendTo('div#right_column ul#tracked_tags');
var NewPosts = function(){
jQuery('div.tracked_tags > div').each(function (i) {
var thisIndex = jQuery(this).index();
if (jQuery(this).find('small').length){
var postCount = jQuery(this).find('small').text();
jQuery('div#right_column ul#tracked_tags li:eq('+thisIndex+')').find('.count').html(postCount.replace("new posts", "") );
The problem has been solved! Someone on another site IDed the culprit as jQuery = $ = p.jQuery.noConflict();; since I wasn't loading my own copy of Jquery I didn't need noConflict, and its usage was hiding Jquery from the rest of the page.

WMD editor freezes Internet Explorer 7 for 3 seconds on load

I am using the WMD editor's original code (not the Stack Overflow version) since I need multiple of them on the same page and Stack Overflow's version makes heavy use of element IDs internally since they aren't going to be having more than one editor instance per page.
The code runs fine in Firefox 3.5, etc. However, when I run it in Internet Explorer 8 (in Internet Explorer 7 compatibility mode), it freezes the whole browser for about 3 sec. before a new instance shows up. I tried profiling it with Internet Explorer's development tools, and it seems that the getWidth() function on line 520 of the minified version of the code is taking up all the time. However, when I tried to hard-code the return (since it was always returning the same thing), the bottleneck shifted to the getHeight() function.
I am attaching the code I am using to convert it to a jQuery plugin.
jQuery.fn.wmd = function(params) {
function createInstance(container, params) {
/* Make sure WMD has finished loading */
if (!Attacklab || !Attacklab.wmd) {
alert("WMD hasn't finished loading!");
var defaultParams = {
width : "600px",
rows : 6,
autogrow : false,
preview : false,
previewDivClassName: "wmd-preview-div"
if (typeof(params) == "undefined") {
var params = defaultParams;
else {
var params = jQuery.extend({}, defaultParams, params);
/* Build the DOM elements */
var textarea = document.createElement("textarea"); = params.width;
textarea.rows = params.rows;
var previewDiv = document.createElement("div");
if (params.preview) {
/* Build the preview manager */
var panes = {input:textarea, preview:previewDiv, output:null};
var previewManager = new Attacklab.wmd.previewManager(panes);
/* Build the editor and tell it to refresh the preview after commands */
var editor = new Attacklab.wmd.editor(textarea,previewManager.refresh);
/* Save everything so we can destroy it all later */
var wmdInstance = {ta:textarea, div:previewDiv, ed:editor, pm:previewManager};
var wmdInstanceId = $(container).attr('postID');
wmdInstanceProcs.add(wmdInstanceId, wmdInstance);
if (params.autogrow) {
// $(textarea).autogrow();
if (jQuery(this).html().length > 0) {
var wmdInstanceId = jQuery(this).attr('postID');
var inst = wmdInstanceProcs.get(wmdInstanceId);
else {
createInstance(this, params);
jQuery.fn.unwmd = function(params) {
var wmdInstanceId = $(this).attr('postID');
var inst = wmdInstanceProcs.get(wmdInstanceId);
if (inst != null) {
wmdInstanceProcs = function() {
var wmdInstances = { };
var getProc = function(wmdInstanceId) {
var inst = wmdInstances[wmdInstanceId];
if (typeof(inst) != "undefined") {
return inst;
else {
return null;
var addProc = function(wmdInstanceId, wmdInstance) {
wmdInstances[wmdInstanceId] = wmdInstance;
return {
add: addProc,
get: getProc
Any help would be much appreciated.
Maybe the freeze in load time is due to IE 7 rendering the JavaScript. Firefox may be faster at rendering and so it makes IE appear to freeze.
