By popular request I have made my JavaScript minimizer and obfuscator available for download. The jsobf program strips JavaScript source code down to the minimum whitespace required to separate the tokens, and performs automatic semicolon insertion to completely irradiate the need for line breaks. It also offers some obfuscation by renaming identifiers.

Also available here is a JavaScript formatter, jsfmt, which reverses the minimizing process. This is useful for inspecting untidy source code, or code that has been minimized for obfuscation purposes.

» Download jsfmt-1-0

Both these programs are PHP command line scripts and require at least version 5.2 of the PHP CLI binary. Windows is not supported, and probably never will be.

I hope you find them useful.
