cnaz

cnaz is an alterative interpreter for naz, written in C. The primary objective for this interpreter is to use an unbounded integer type for the unlimited mode naz -u, instead of the floating point based number type used in the javascript interpreter.

Usage

After cloning the repository you can compile the interpreter with

$ cc -std=gnu99 -o interpreter interpreter.c nazlib.c

and run the interpreter with

$ ./interpreter filename.naz

This reposity is currently only written for UNIX and only tested on Debian / Ubuntu.

Differences

Currently, cnaz can only run a subset of naz programms. The following list shows all the additional restriction for naz programs to be executed by cnaz:

• Comments and spaces cannot be placed between the number and the operand. 1r 1o is fine, 1 r1o is not.
• Special opcode blocks (1xNf; 2xNv; 3xNvMg ; 3xNvMe and 3xNvMl) cannot be interrupted by spaces or comments
• Error checking is less strict, for example loading an undefined variable will not (necessarily) result in an exception
• Only -u as a command line option is supported
• Contrary to the default naz -u interpreter, Unicode codepoints from 0x10000 to 0x10ffff cannot displayed. Trying to do so using two Unicode Surrogate codepoints (0xd800 to 0xdfff) like here will fail.
