Many other languages already exist, such as Lua, Tcl, or BASIC; however, most implementations require certain system calls like a read() and write(), as they expect a filesystem. This interpreter aims to be as independent and portable as possible: parsing script from strings one at a time, having minimal built-in functions (so the user can define their own prints and such), and only requiring a few standard library functions. -To use this program with your own device, only one function is truly neede: malloc, and calloc (though may switch to only malloc). +To use this program with your own device, you need some malloc/free implementation, and string functions like those in string.h, atoi, and snprintf. Some of these functions may become coded in so that a standard library isn't required. -Current features: +Only a few commands are built in to the interpreter: +* set - set variables +* func/end - define functions +* jmp - jump to line + +Other features: * function/variable defining in c -* variable definition -* function calling with variable expansion +* expression solving + +Soon: +* conditionals +* error messages This project is still in heavy development, so don't expect much. To include it in your own project, just link in parser.o and use the header files. |
