Best Mac text-editor to replace Homesite on a PC?

I think http://www.barebones.com/products/bbedit/ is the only other major player in the OS X text editor field that you haven't looked at yet. I know a bunch of folks who swear by it. Bare Bones also makes http://www.barebones.com/products/textwrangler/, which is free. Not sure if these meet your requirements, but they're both worth trying out.

I've been using Textmate with Transmit to remotely manage sites for the last few years after about 7 years of Homesite use. http://muffinresearch.co.uk/archives/2006/06/13/use-tabs-in-textmate-for-remote-files-opened-by-transmit/ to do multiple files in multiple tabs in the same window (as opposed to multiple windows). Also, I had to hand-write keystrokes in the Bundles area to match what I was used to in Homesite for quick markup writing.

The most acceptable Mac text editor I've found is Jedit, which is a java-based application. It has lots of plugins that I think do what you want. On the downside, it is a little bit crashy and a little bit ugly. YMMV, and I myself plan to watch this thread and see if there are any better suggestions.

Whatever the Mac UI guidelines may say, this arrangement really does decrease productivity. The extra few seconds to look at and scroll the list, repeated several times a minute over the course of a day, really do make a big difference and completely interrupts my train of thought. I think I'm going to just stick with Homesite in VMWare until something better comes along.

Textmate would be marginally acceptable if I could just click on a folder to open it. But no, it completely ignores clicking on a folder, and you have to twiddle the little arrow thing and wait for it to animate. As WCityMike http://ask.metafilter.com/138561/Best-Mac-texteditor-to-replace-Homesite-on-a-PC#1980700, this is another example of your opinion being at odds with Mac UI guidelines, not specific apps. The "Hypertext Model" of navigation is just Not The Way It's Done in apps on the Mac. Sorry to say, if you're wed to specific functionality like that as deal breakers, you're going to have a very hard time.

Textmate would be marginally acceptable if I could just click on a folder to open it. But no, it completely ignores clicking on a folder, and you have to twiddle the little arrow thing and wait for it to animate. And do so for each level, once the folder you twiddled with opens and there are more folders underneath it. I thought the Mac had a reputation for good software design, but this is ridiculously inane.

I come from Crimson Editor on the PC side, and absolutely loved it. Column editting allows me to work with huge data sets, and I can easily clean them up using Crimson. Also, the macro feature makes life quick and easy. Now that I am OSX based, I too have searched for a text editor of the quality, speed and just good ole' logic that CE provided. I tried TextWrangler, but found it obstructive and more oriented to programmers than to me. That having been said, maybe if you are a programmer TextWrangler is your date. I guess I will have to keep an eye on this thread. I would prefer Crimson for OSX though.

You will be hard pressed to turn off antialiasing anywhere on your Macintosh. It is technically possible at the application level, but rarely done, and when you encounter it the reason is often because it’s an old Carbon application (like versions of DataComet before the current one). BBEdit can show you directories of files in several ways, including a useful project view that enables you to group noncontiguous files together. Of course you can just double-click a folder in any such listing. BBEdit has multifile search and replace with GREP. It takes a while to arrive at settings you can really live with on BBEdit. To start with, default fonts are atrocious, even given your stated constraints (which merit investigation and are not uncommon among programmers; you may be colourblind and not know it). But so much is customizable that once you’ve got things fully dialled in, you won’t want to leave.

I haven't been able to give up HomeSite, which is why I'm running XP with Parallels. That and the ability to proof pages while I'm working on them. Believe me, I've looked, and there's nothing that matches the instant gratification of working in HomeSite. Dreamweaver is to poky, bloated, and crashy for me. It needs a diet and a good UI redesign. Most of the gripes I have are with the different approaches to workflow that all of the other apps require, and that I can't stomach. I'll take another look at TextMate, though.
