Here's a very good article about different text-editors for OSX - personally, I'd say Sublime Text is the best bet, but that's mostly because I fell in love with it on Windows, after using Notepad++ for a long time before someone pointed me to Sublime. Here's the link: http://mac.appstorm.net/roundups/web-dev/the-best-code-editors-for-your-mac-in-2013/ I've also heard a lot of good stuff about Textastic, but haven't tested that one myself, unfortunately.
When I'm stuck on a Quackintosh, I either use VirtualBox or Fusion in seamless mode to run the windows editor I like (Flo's Notepad2) or I use text-wrangler. Text wrangler's a fine and simple editor, though I tend to turn most of it's fancier useless crap (like colour syntax highlighting) off since it just gets in my way. I wanted to like sublime, but like most Java crapplets it pisses me off so bad on Windows I've never given it a chance on any other platform. Actually, is it a java crapplet? I can't remember -- I know it sure as shine-ola behaved like one when it came to illegible text, ignoring the host OS settings, and not even TRYING to look like a native application... I do know on windows the installer crashed explorer.exe, preventing me from even installing it on win7.
Deathshadow: Sublime works perfectly fine on Win 7 (and 8). It's a normal, standalone app, running in standard Windows-mode/look/feel. You can pretty much set it up as you please, be it all one color text, or syntax highlighting etc. It has built in Build-functions for different types of code (which, knowing you, you'll hate - but it's voluntary to use), etc.
Just tried it again here, x64 installer crashes on win 7 x64 just like before... forced a download of the 32 bit version and that runs. funny with the goofy non-standard scrollbars, absurdly undersized illegible fixed metric fonts that ignore the system metric on things like the status bar and tabs, it reeks of being written using SWING or some other toolkit that pretty much doesn't even TRY to leverage the native UI. BULLSHIT... LOOKS like a bizarre cross between a mac program and a swing app running on windows with, well, read that last section with the non-standard (and useless) scrollbars, illegible undersized fonts, ignoring the host OS color styles on all the window chrome... Are we even talking about the same program? Yeah, I'm still hunting for that -- seems like everything is buried in dicking around with pointless (and actually overdocumented) config files... where half the values you set don't seem to do what they say or have to be done in some other file (in which case why the **** put them in all the files) I'm more troubled by it's inability to automatically put everything in it's own window and shoving the tabbed editor crap down your throat -- but that's why I won't use editPlus or notepad++ either. It's such a step BACKWARDS in functionality when you have a perfectly good taskbar and a high resolution display to crap everything into one window when coding. Probably why I don't like IDE's either -- that whole project management crap just making code harder to work with -- as if looking at two or more files side-by-side, using a decent OS file manager, and using logical names and sensible directory structure is some sort of radically crazy idea that needs to be pitched in the trash for automated tools that make a right mess of everything because that makes it "easier" -- right.
You can have a vertical list of the open documents, and turn off the tab functionality? And, okay, I'll give you the non-standard scrollbar, which I don't really care about (when in the world does anyone use a scrollbar?) two fingers on the touchpad, or the scrollwheel on the mouse works faster. As for the ignoring the UX-choices of the OS, that might be - I admit that I run standard AERO, and never adjust OS-zoom or text-scaling or anything like that. I tested now, and yeah, I see that the tab-text is not scaling. That might be a problem, of course. I'm running x64 Sublime on Win 7 x64, and it still works just fine... However, running the 32bit version instead doesn't really matter, does it? It's a text-editor. If you need to access more than 4GB RAM or something else pertaining to 64bit architecture on a text-editor, something else is wrong somewhere As for getting rid of the color-syntax, just delete the content of color_scheme in the settings->user-file. That will turn off any syntax highlighting.
I personally use Komodo Edit 8. It's really nice. It does that 'auto finish' thing on some of your syntax.
You'll spend more time trying to find the "best editor" and trying out new editors than developing your project on an etch a sketch. Most "highline" (popular) editors are so customizable you can make them appear and function close to whatever you are looking for. You simply need to learn how to use the editor. Eclipse w/Aptana is nice. But honestly you need to write down on paper exactly what you expect out of an editor. For Web Development I want Syntax highlighting/coloring, an advance Replace/Find tool, Collapsable code brackets, ability to Debug/Validate from the IDE, ability to preview within the IDE and externally, and a practical use of auto fill/complete. 100% of the editors do what I need. Yet I have gone through 20+ editors over the years to only go back to basic editors like scite or notepad++. Most editors are jammed packed with fluff you will NEVER use. Hell, most of them have features that barely even make sense to use. If you want an advanced editor check out Eclipse or Netbeans. If you want a code editor focused with a notepad on steroids feel check out SciTe or Notepad++. But you will never be happy until you take the time to get use to the editor by actually using it for real projects.
... and that part right there mirrors my experiences with editors, just I'm a bit more extreme about it as about most of what you say you want I don't and honestly just turns people into crappy coders... I don't want some third party debug/validate crap because it rarely if ever works like the real deal and logs/debugging info aren't THAT hard to use. I don't want some goofy preview pane as they don't behave like the real browsers and one should be testing changes in all REAL browsers ANYWAY -- that just promotes bad habits. I HATE auto-fill/complete because most of the time it doesn't actually do what I want where I want it, and by the time I get a handle on figuring out what it's trying to do or correcting the half-assed crap it did, I could have typed the damned thing in ANYWAYS. I don't want the goofy illegible acid trip of color that makes the text impossible to read... I don't want collapsable code... But a good search replace, preferably with regex compatibility? Serious "Must have".
