Loops

Silicon has exactly one looping contruct, @loop or @for

// TODO: copy from zzz_experimental Silicol has one overloaded @loop construct. They are also expressions.

// grammar
Loop = "@loop" (condition | iterable), function

FOR with step

For loop with step 2 with range syntax

Function

// 1,3,5,7,9,11...
@loop 1..3..100, @func _ i = {
    #print i;
};

Lambda

// 1,3,5,7,9,11...
@loop 1..3..100, \i = {
    #print i;
};

For Each

Function

@loop students, @fn _ student = {
    #print i;
};

Lambda

@loop students, \\student => #print i;

WHILE

Function

@loop i < 100, @func _ i = {
    i += 1;
    #print i;
};

Lambda

@loop i < 100, \\i = {
    i += 1;
    #print i;
};

DO WHILE

// new grammar with function?

@loop _, @fn i:mut = {
    i += 1;
    #print i;
    @if i >= 100 $then @exit;
};

NEW ideas for WHILE loop

New Ideas to keep loop grammar consistent. 21 JULY 2024

First parameter should be an iterator.

@name i = 0
&@loop _, @func _ i = {
    i += 1;
    #print i;
    &if @not i < 100 
    $then #Done 
};
