What is a good Scheme IDE for Windows? OK, I'll admit it; I'm not at RMS's level, and don't want to use Emacs or any character-based interface -- I want a graphic IDE with colorization, a REPL, and usable, in-line help for a specific, well-documented dialect of Scheme. I have searched around and PLT Scheme/DrScheme seems the best, but even that does not look too sophisticated.
Answer
DrScheme is the best Scheme IDE I have found. It has a JIT compiler, can build stand-alone executables or run in the traditional Scheme REPL, has smart syntax editing , as well as other traditional IDE features like Menu bars to change features. Running/stopping your program is as easy as clicking 'Run'/'Stop'. It also includes a macro-expander (if you're writing macros) as well as a debugger. It's Help menu includes both DrScheme-specific documentation, as well as various Scheme specifications (e.g., R5RS and R6RS).
If there is something you want in a Scheme IDE that is not in DrScheme already, I'm sure the developers would be interested in hearing from you.
