The Status-bar Calculator extension will soon be available on Google Chrome. You can watch me code it here:

http://etherpad.com/statusbarcalculator

I might take this opportunity to set up a Git project for it… but it appears the code will be short/simple enough that I can actually do all development right in etherpad.

If anyone wants to join in, hop on and start typing away. Don’t forget to enter your name on the right so you can get credit for helping out.

I just realized I had never officially “branded” the extension with the MIT License as I had planned to do for some time now. Well, here it is:

You can check out a copy from my subversion repository here (this has been available for some time now): http://statusbarcalculator.com/statusbarcalculator

Write a patch/feature/etc and if you submit it (and I accept it, which will most likely happen unless it just doesn’t work) I’ll include you on the official firefox page as an author or contributor (depending on the size of your submission).

Special thanks to everyone who has already contributed so far:

• Tom Kennedy
• Jerrie
• Mike Daniels
• Fernando Aguirre Baeza

Some feature ideas:

• Make the -, +, *, /, ^ keys work with Mac OSX
• Make preferences to allow moving the calculator around in the browser
• Allow for localizations
• Number history for each textbox (so you can click on the box and see a pop-up with all previous numbers you have typed in it in case you want to go back to a certain point in the calculation)

Other than that, the code was written as a college project (so it’s not that spectacular). It could really use a massive overhaul, maybe integrate jQuery or something.

If you are interested in working on this project, and want to talk with me about it, feel free to comment on this post, or send me an e-mail at cmcculloh at this domain.

I’ll probably be replicating this extension in Google Chrome when they come out with extensions for that…
