I’m a long time BBEdit user but I do keep an eye out for Mac text editors. Chocolat is a new text editor for the Mac that might be worth looking at, it supports split-window editing, code folding, and code completion. It can be used for a wide range of programming and scripting languages.

KosmicTask is an integrated scripting environment for Mac OS X. Whilst Mac OS X supports a number of scripting technologies either via it’s UNIX roots (Shell scripting , Perl etc.) or via Cocoa Framework Scripting using Apple’s scripting bridge (Applescript, Ruby, Python etc.) you can end up using a different script editor for each scripting language. KosmicTask allows you to script in a wide variety of languages from within a single editor. KosmicTask uses a plugin architecture that allows it to support a range of scripting languages, details of the languages supported by KosmicTask are shown below:-

• AppleScript
• AppleScript Cocoa - AppleScriptObjC
• Bash Shell
• C Shell
• C and C++
• F-Script Cocoa
• Java
• JavaScript
• JavaScript Cocoa - JSCocoa
• Korn Shell
• Lua
• Lua Cocoa
• PHP
• Perl
• Python
• Python Cocoa - PyObjC
• Ruby
• Ruby Cocoa
• Tcl
• Tenex C Shell
• Z Shell

KosmicTask also supports another very capable means of achieving automation - appscript. Appscript is supported by both Ruby and Python an alternative to the ScriptingBridge. 

It also allows sharing of scripts with other KosmicTask users via the local shared network.

I’ve also added it to the list of Applescript Resources.
