I've used BBEdit for 12 years, and aside from a handful of annoyances am pretty happy with it. It's an editor not an IDE, but its list of languages include:
ActionScript, ANSI C, C++, CSS, Fortran[9x], Grep, HTML, Java, JavaScript, JSP, Lasso, Lua, Markdown, Object Pascal, Objective-C[++], Perforce, Perl, PHP, Python, Rez, Ruby, Setext, SQL (5 dialects), Tcl, Tex, Unix Shell Script, VBScript, VectorScript, XML, YAML. My only wishes would be for Verilog and VHDL for my day job.

First-time cost for an individual is $125, educational $49, upgrade $30. There have been maybe 6 costed upgrades in 12 years?
