This [[D]] implementation supports commands from all the three SNUSP variants, as described on the [
'''SUPERNATURAL Mode''':
Line 7:
#Read the char in current code pointer as input, assign it to memory currently pointed to by memory pointer.
*'''* : join and wait tasks''' (telepathy):
#A task
#A task is by default initialized as free-state;
#When a free-state task first executes this '''*''' command, the task enters into a join-state;
#Then if a join-state task executes another '''*''' command, the task enters into a wait-state;
#A wait-state task stops its execution, and waits until all alive join-state tasks are
#This command enables global synchronization of the tasks.
#Difference to original specification:
Line 16 ⟶ 18:
::*In this implementation, the order of execution is first-created-first-executed;
::*The original specification specifies that ''(&)SPLIT''-ed old thread skips the immediate code (see below a->b->c->d example), which may lead to anti-intuition codes (which is good for an esoteric language :). This implementation retain old-thread-skips-immediate-code behavior in ''BLOATED'' mode, but new-thread-skips-immediate-code in ''SUPERNATURAL'' mode ( A->B->C->D example). 1->2->...->8 is thread creation order in ''SUPERNATURAL'' mode.

▲::*The splited new thread inherites free/join/wait-state from the old thread.
▲*'''^ : wrap''' (teleport):
#The code pointer will bounce back to the code space boundary in its reverse direction;
#then forward and stop after the first '''^''' it encounter in normal direction.
#Example :
<d>module snud ;▼
:::==a^A<=cp==B^==<=C^==
::when the code pointer cp heading into A's^, next turn, the code pointer will be in C. if no such ^ in the reverse direction, the code pointer will be in ''a'' next turn.

Sample SNUSP using a console io :

import snud ;
import std.stdio, std.file, std.conv ;
Line 259 ⟶ 263:
return result ;
