jsgen
JSGEN is an extension to AllegroServe that allows one to write JavaScript programs in an s-expression syntax. The primary advantage of this approach is that the user has the ability to extend the language using macros, resulting in shorter more manageable programs. A disadvantage is that the debugging of programming errors within a web browser will require working with the generated JavaScript code. Errors raised in the browser will have to be manually traced to their source within corresponding s-expression code. JSGEN is a good choice if you believe the benefits of syntactic abstraction (shorter programs, fewer bugs) outweighs the cost added to the debugging process.
