*** HIGHLY EXPERIMENTAL *** DON'T USE ***

This experiment is trying to answer a few questions:

Q: Can we have an system language to build declarative ui ?

NOTE:

i hope you have memory... currently it doesn't free anything :D

Quick Sort Example

#import "modules/std.sx";

quickSort :: (items: []$T) {
    partition :: (items: []T, lo: s32, hi: s32) -> s32 {
        pivot := items[hi];
        i := lo - 1;
        j := lo;
        while j < hi {
            if items[j] < pivot {
                i += 1;
                tmp := items[i];
                items[i] = items[j];
                items[j] = tmp;
            }
            j += 1;
        }
        i += 1;
        tmp := items[i];
        items[i] = items[hi];
        items[hi] = tmp;
        i;
    }

    sort :: (items: []T, lo: s32, hi: s32) {
        if lo < hi {
            pi := partition(items, lo, hi);
            sort(items, lo, pi - 1);
            sort(items, pi + 1, hi);
        }
    }

    sort(items, 0, items.len - 1);
}

main :: () {
    arr := []s32.[1, 2, 3, 5, 2, 2, 3, 4, 5, 6, 6, 1];
    quickSort(arr);
    for arr {
        if it_index > 0 { write(", "); }
        print("{}", it);
    }
    write("\n");
}
