One of the things that changed is the way it handles scripts and text filters. If you don’t want to read through the whole thing, here’s the main part:

There are two fundamental types of runnable file: “text filters”, which accept the selection range (or entire document, if no selection) as input, and which return text that replaces the selection range (or document); and “scripts”, which do neither. In unix-y terms, text filters accept the selection range on STDIN, and STDOUT replaces the selection range.

It just happens that I use XML Tidy a lot to format xml documents in a pretty way. To do that I had a nice little script (which is just a xmllint command really) for which I assigned a shortcut (alt+cmd+p). That made my workflow pretty fast. The problem is that this script stopped working as before so it took a while to find out why but I found a thread in google groups about this issue and someone from Barebones helped find the solution.

So in summary, here’s what you have to do to make XML Tidy work again in TextWrangler 4.0:

• Paste this into a file

#!/bin/sh
XMLLINT_INDENT=$'\t' xmllint --format --encode utf-8 -

• Save with the name tidy.sh under ~/Library/Application Support/TextWrangler/Text Filters/
• Open TextWrangler, write some unformatted xml, and try it out from Text menu > Apply Text Filter
• To make it even easier, go to Preferences > Menus and Shortcuts and set a shortcut like I did (alt+cmd+p)

Hope that helps!

AVG Free 9.0

If you don’t you should care about viruses and malware. It’s all over the internet. But forget about expensive antivirus and security software packs like Norton antivirus that make your computer crawl like a slug. AVG has a free version of their antivirus software that has everything you need plus some stuff you probably don’t – like the link scanner thing which is the first thing I disable after installing.

ImgBurn

I used to be a Nero user, but after finding out about this free piece of DVD burning software I switched. It’s faster and simpler, and that’s all that there is to it! You can burn everything with this, files, images, music, you name it.

Tip: if you’re looking for a portable solution you can try InfraRecorder portable.

VLC Media Player

PrtScr

I featured this one on my previous post so it’s obviously worthy of being featured in this list also. It’s a real pleasure to take screenshots like this. I love it when such simple tasks become so easy and so cool!

RocketDock

In case you’re like me and have always stared at MACs and their gorgeous launcher bar with all the bells and whistles and wondered why the hell doesn’t Windows have something like this – well, now it has, and it’s free. This is particularly useful for me with a dual monitor setup. Now I can free up the quicklaunch icons from Windows task bar and put all my shortcuts on the RocketDock on the 2nd monitor. It’s completely customizable so you can play around a bit and get some new icons.

This is not really an essential tool… unless you have that nasty habit of throwing everything you find in your desktop which eventually becomes a really big mess which mimics your real life desk. Fences is like Ikea for your desktop. You keep the same shit around you, but you put in boxes so that it looks nicer!

TeraCopy

This is a very compact tool designed to make copying and moving files easier and faster than usual. Like they say: TeraCopy uses dynamically adjusted buffers to reduce seek times. Asynchronous copy speeds up file transfer between two physical hard drives. It integrates seamlessly in the shell and has some additional features also. Very handy.

If you still miss any, Notepad++ is totally extensible, you can add whatever you like in there!
