hi. i'm looking for a text editor on mac os x that has syntax highlighting for languages like C, C++, java, PHP, postgresSQL, LaTeX. i heard textmate and bbedit are good editors, but it surprised me to find that not only did they cost money, but they were pricey. i would never pay that much for a text editor. i'm not after spectacular features, just an equivalent to kate on linux. or is there kate for OS X too? thanks.
