# interpreter
|
|
This project aims to provide a very minimal scripting language for embedded systems. 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, 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.

Only a few commands are built in to the interpreter:
|
|
* set - set variables
|
|
* func/end - define functions
|
|
* if/end - if conditional
|
|
* do/while
|
|
* ret - return value from function
|
|
|
|
Other features:
|
|
* function/variable defining in c
|
|
* expression solving
|
|
* no local variables
|
|
* whitespace hopefully ignored
|
|
|
|
Soon:
|
|
* error messages
|
|
* arrays?
|
|
* maybe for loops
|

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.
