Summary

A programming language for 'Golfing' in an assembly-like/lite environment.

- Spice is an interpreted assembly-like language with a handful of operators: ADD, `SUB`, MUL`, `DIV`, `MOD`, `PUT`, `GET`, `SWI`, `BRK`, `ALS`, `OUT`, `LOD`, `SIN`, `COS`, `TAN`, `POW`, `REA`, `CLR`, `LEN`, `NUL`. For full descriptions of each operator see the link to the language README in the resources section - Spice programs are split into two sections; declaration and instruction, split with an @ character. - All values are dynamically sized double arrays with the exception of string literals, "Some string", which may be used in OUT statements, but not stored - The end of instructions is denoted by a user-defined character - the first character of the program

Example code

Hello world:

 ;@
 OUT "Hello World"

Or, doing slightly more useful things:

 ;in;temp;res;@
 OUT "Addition calculator - first no:";
 REA in;
 OUT "second no:";
 REA temp;
 ADD in temp res;
 OUT "= " res;

Example module for sorting a passed array from the standard library (std::sort.spice):

 ;unsorted;unsortedVal;currSorted;outerIterator;innerIterator;unsortedLength;sortedLength;finalSortedIndex;return@
 LEN unsorted unsortedLength;
 NUL initalise outer counter to 0; 
 ADD 0 0 outerIterator;
 NUL ===== START OUTER LOOP =========;
 GET outerIterator unsorted unsortedVal;
 LEN return sortedLength;
 SUB sortedLength 1 finalSortedIndex;
 ADD 0 -1 innerIterator;
 NUL ===== START INNER LOOP =========;
 ADD innerIterator 1 innerIterator;
 NUL deal with over-running end of list;
 SWI finalSortedIndex innerIterator 15;
 NUL otherwise, get the current val, and if it's more than unsorted, insert at innerIterator-1;
 GET innerIterator return currSorted;
 SWI currSorted unsortedVal 8;
 NUL ====== END INNER LOOP ==========;
 PUT innerIterator return unsortedVal;
 ADD outerIterator 1 outerIterator;
 SWI outerIterator unsortedLength 3;
 NUL ===== END OUTER LOOP ===========;

Interpreters

A single Spice interpreter exists. See Resources.
