character

The character classes are used to define what a keyword looks like. For instance, in the C language, the acceptable characters making up a symbol are the upper and lower case letters, the digits (0-9) and the underscore. ABC_DEF is a perfectly valid symbol name. In some other language, maybe the underscore is not valid; in shell scripts, the dollar sign is used to introduce a symbol but can also terminate a symbol name, e.g. $HOST$PWD. The character class definitions are pseudo-regular expressions containing character classes using the [..] notation.

Testimonials

"After using Brief for many years, I did not look forward to learning vi or Emacs on my UNIX machine. CRiSP came to the rescue. The program has now grown and matured to the point where it has become much better than Brief ever was."
