Using JSLint with Notepad++

I’m doing a fair amount of development using the ExtJS framework. IE is a bit picky about getting JavaScript properly formatted (otherwise it refuses to render the page). That’s why I’ve found JSLint really useful for locating stray commas or semi-colons.

To make it a bit quicker to put the file contents in the JSLint box I decided to hook it up to the Run menu in Notepad++. However, the JSLint web page doesn’t allow us to pass in data to it. To get around this you can copy the HTML + JS files from the authors website an copy them locally. Once you’ve got them locally you can modify the source to allow the passing of data.. here’s the change I made to do it on my system:

jslint.php changes.. add this right near the end

<script src="javascript.js"></script>

You’ll then need a way to take the file contents and fire it off to the page. At first I tried passing the file contents via the GET request, but it’s limited in length. Also, Notepad++ won’t let you send the file contents via the Run command. In the end I chose to use a piece of VBScript to bring up the webpage in the default browser, and some JavaScript to read in the file & place it into the page.


Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(wscript.Arguments(0), 1)

Dim strCharacters

Do Until objFile.AtEndOfStream
    strCharacters = strCharacters + objFile.Read(1)

strCharacters = Escape(strCharacters)

Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set objOutputFile = objFileSystem.CreateTextFile("c:\progra~1\notepad++\jslint\javascript.js", TRUE)
objOutputFile.WriteLine("document.getElementById(""input"").value = unescape(""" & strCharacters & """);")

Dim wShell
Set wShell = CreateObject("WScript.Shell")
wShell.Run "c:\progra~1\notepad++\jslint\jslint.html", 9

Finally, this is the Run command you can use in Notepad++ to launch the script…

wscript "C:\Program Files\Notepad++\launchJSLint.vbs" "$(FULL_CURRENT_PATH)"

USB Detect & Launch Version 1.4 Released

USB D&L This new version includes the ability to detect when devices with no label are inserted. This is handy when you have a whole stack of new devices that you need to put data onto.

Here’s an example of the syntax you’d use:

label:(no label)
exec:”c:\batch\batch-no-label.cmd” %1 %2
