#392 — How to write an interpreter?

Excuse me ladies and gentlemen, I'd like to write a Basic interpreter. 
I have in mind old-style Basic such as is described in

   Basic programming, Kemeny & Kurtz, Wiley, 1967 (!)

Any suggestions of what I might read?

Depends. I'd suggest reading through Jack Crenshaw's "Let's Build a 
Compiler" tutorials:

  http://compilers.iecc.com/crenshaw/

Part 4 discusses interpreters, but you'll probably want to start from the 
beginning. It's not BASIC, and doesn't resemble it in any way, but it can be 
really helpful.

What a great excuse you use for ducking the question.

Even without a book, what you have in hand maybe enough, if your 
command of programming is good.

If you think about it, an interpreter is not quite different from any 
other app. The main difference is that the UI is line based. Most of 
the job of an interpreter is to react to command line and display the 
result, make sound (if limited to beep) or send the output to a 
printer. Programs are just a list of command lines, placed into a text 
file. At the time, most Basic did not even interract with disks.

The PRINT command is extremely simple to implement and play with, since 
its result can be seen on the screen right away. A small detail has 
changed between early Basic and today, though : at the time, screen was 
20 lines of 40 characters or so. Then it doubled to 20 lines of 80 
characters. But our current environnement is graphical, and you will 
have to translate coordinates. Same thing for color instructions. Same 
things for graphical instructions if any (an't really remember what was 
around in 67).

Output to the printer can be a small challenge as well : line printers 
of the era where teletypes, meant to show the output on top of the 
unit, line by line. Today's printers are mostly page oriented. You can 
still attach line printers to a PC, through a serial card, but it may 
not be that easy to manage through Windows API. It may require a bit of 
under the hood programming. Or you can create a small screen app that 
will show the result of the line printer for interactive, and send to a 
modern printer when enough lines can grant a page.

Starting with a 67 book is an excellent idea, because you start where 
most interpreters started. You can then follow evolution to more modern 
versions. Sounds like a very interesting endeavour.

Good luck !

Hello,

If you plan to write it in the C language you can have a look at 
http://wifichezleschtis.free.fr/bison
It is not finished at all. It uses lex and yacc and works on both linux and 
windows.

Best regards,

You were replying to a two year old message, in a newsgroup that is not 
well used.
