I want to write a scripting language something like Hypertalk for a program I am writing. I have never written a language before, so I am not quite sure where to begin. Can anyone give me some broad words of wisdom on what the general approach to writing an interpreter is? I know this is a very open-ended question, but I would appreciate any guidance you could give me (even if the concepts seem glaringly simple to you, because as I said, I've never done this before). --Kurisuto (who is not Vasile) email un020070@vaxa.wvnet.edu (not vrm@babcock.cerc.wvu.wvnet.edu) Thank you!

Start with Lex and Yacc. These are standard unix tools. I have used
MacYacc in the past, and MPW has variants as well. After that, it
should be pretty application dependent...
So when will scripting be available under system 7.0? I see it as
a tight race between the single European market ('92) and apple
scripts.

The most obvious is xlisp by David Betz. The code is very portable, well tested, and available from many archive sites. In addition to xlisp Betz has written xscheme and ExTalk. ExTalk is specificly designed as an "embedded languaged." I found ExTalk on Byte's bboard. Good luck. -- Andrew Gilmartin (andrew@brownvm.brown.edu)
