There is an IDE called Komodo, put out by ActiveState. This displays errors before you run the code - as you type. In fact, it's annoying, because if you enter an opening parenthesis, quote, brace, etc., it flags everything as an error until you close the offending container. However, it is handy for catching most of the mistakes.

ActiveState has Windows and Linux versions of Komodo, and I've used it on both systems. There is a personal version for fairly little money, and a professional version for big bucks. However, the license for the product is to the user, so you can put this program on any computers you want, as long as you're the only one to use the program.

Komodo isn't perfect, and it's no substitute for careful planning and coding, but it does help catch those typos and other silliness we tend to do.
