Tools: ideone, RegExr, jitouch 2, open, ditaa

Through reading proggit and hearing about new technology from classmates, every once in a while, I build up a list of tools which I plan on checking out and see whether they’re useful enough to add to my regular routine. The first four on this list fall into that category, and I may eventually find a use for the last.


ideone is an in-browser, syntax-highlighted code editor complete with interpreters and compilers. Basically, if you’ve ever wanted to try out a language but really didn’t feel like installing it on your system, this is the perfect place to start. The site even runs Brainf**k.

There’s another site which accomplishes the same task, but less elegantly: Codepad. This site is so much less elegant that I wasn’t originally planning on posting it, but decided to once I saw there was a Codepad vim plugin. There’s also emacs integrations.


Regexr is an online tool, implemented in Adobe Flex, to test out regular expressions in real time. If you haven’t learned about regular expressions yet, go learn right now. They’re just about the most powerful text matching, user verification and error correction tool in existence. They’re also implemented in nearly all languages now in some form or another. Before I saw this site, I would test out all my regular expressions just using vim, but found it frustrating when the expressions needed to be changed to be compatible with php. So I’m likely going to start using RegExr instead.

jitouch 2

Jitouch 2 is an application expanding on the multi-touch gestures available to MacBook Pro users who want to do more with just the touch pad. The two big things that this enables me to do that I love are opening links in new tabs using only taps on the keypad, and switching tabs using a gesture equivalent to ctrl-tab to switch tabs. I actually saw this reading Randal Munroe’s blag.

Mac OS X/Gnome open

open & gnome-open are terminal commands in Mac OS X and gnome respectively, but they do the same thing. Whenever you double click on a file in Finder or Nautilus, the operating system has a database of which extensions are opened by which applications. You can leverage that database by calling open. Examples:

open "Office Space.avi"

Open up Office Space in your default viewer.

open http://www.jamie-wong.com

Visit my website from the commandline, opening in your default browser

open -a "Adobe Photoshop CS3"

Launch Photoshop. open -a opens files with an application.


ditaa is a tool for converting ASCII art diagrams into graphical diagrams. This is pretty well illustrated in the picture to the left. I haven’t actually found much of a use for this yet, but some of you might.
