Web Developer Workflow?

I bought my mac basically for programming. What are the MUST applications? So far I have textmate.

I want to study ruby and php.

What do I need on my computer for local development, and what do I need to lower my stress levels by helpful applications?

Thanks,
Daniel

Here you will find some of the most useful Apps.

BBEdit. If you can't afford BBEdit, then use TextWrangler until you can.

Smultron. It kicks *** and knows many Syntax formats.

emacs

I'm a web dev who made the switch. I'm currently using Smultron for editing, it handles PHP, HTML, CSS fine and I'm using CyberDuck for FTP'ing. When I first switched the program crashed quite a bit but the latest build seems to be quite stable and I have no complaints.

I highly recommend Eclipse, and BBEdit.

Taco HTML, CSSEdit, DreamWeaver, RapidWeaver, SKEDIT... these are all fun!
