This program demonstrates how to make an interpreter for a programming language. It uses the"Gang of Four" Intepreter design patternto implement a simple, Pascal-like language. It is written in C++ and compiles
This interpreter was made as a product for my beginning level study of programming language, hence, it is simple and crude, use an array of 3,000 byte cells and at most accept 10,000 bytes of characters input. It just test by a limited test set which in the directory test. ###Instal...
Creating anInterpreterinstance is really simple, we just give it a parser. Also, notice how we instantiate an empty dictionary where we will be saving our variables. This is just a hack we are going to use momentarily, while our programs are simple and we don't have things like scopes. ...
Up until now, we had our interpreter and parser code mixed together and the interpreter would evaluate an expression as soon as the parser recognized a certain language construct like addition, subtraction, multiplication, or division. Such interpreters are calledsyntax-directed interpreters. They usual...
For your convenience I put the above code into theparser.pyfile that contains a lexer and a parser without an interpreter. You can download the file directly fromGitHuband play with it. It has an interactive prompt where you can enter expressions and see if they are valid: that is, if th...

on the other hand, can run as is on any platform with an appropriate interpreter; they do not need to be recompiled to run on a different platform. Python, for example, is used mainly as an interpreted language, but compilers for it are available. Interpreted languages are better suite...
Note:Part of the configuration process for setting up the Java platform is setting the class path. The class path can be set using either the-classpathoption with thejavaccompiler command andjavainterpreter command, or by setting theCLASSPATHenvironment variable. You need to set the class path...
What markup language will you use?Markdown. The markup renderer is not a pluggable part but has been internalized into core parts. Discussion should go here:https://github.com/django-wiki/django-wiki/issues/76 Why not use django-reversion?It's a great project, but if the wiki has to gro...
