\*as\*cendant syntax

[Liebranca]

Figure 0:

var@0 =/#/op= var@1;

mamm will have trouble with this because it's fetch first token, check if it's a fetch, then oppy-poppin and finally solving -- and all to repeat the process once again; except this time generate actual instruction tokens and check whether the first oppy is an equals, kush or e-oppy.

This doesn't make any sense. Put instruction then eval once, simple. You know the minimum number of args firsthand, and *all* tokens are translated in the same run.

Thus, figure 1:

cpy var@0, var@1

I have inadvertently developed an interpreter which has a preference for this kind of mock-assembly syntax. And I like it a lot.

So: time to ascend beyond re-thinking and re-designs, this is what we're doing now.

TODOs

• cpy a, b -> a = b;
• mov a, b -> a = b; b ^= b;
• wap a, b -> c = a; a = b; b = c;
• wed type -> sets typing mode; implicit casting

• jif a, b -> jump to a if b
• eif a, b -> jump to b if not a
• entry s -> defines s as program entry point
• exit x -> stops program and returns x

• add a, b -> a += b;
• sub a, b -> a -= b;
• mul a, b -> a *= b;
• div a, b -> a /= b;
• mod a, b -> a %= b;

• and a, b -> a &= b;
• or a, b -> a |= b;
• xor a, b -> a ^= b;
• nand a, b -> a = !(a&b);
• nor a, b -> a = !(a|b);
• xnor a, b -> a = ~(a^b);
• shl a, b -> a<<b; cpy a, a << b;
• shr a, b -> a>>b; cpy a, a >> b;

• til a -> a = ~a
• cl a -> a^=a
• clm a, b -> a&=~b
• not a -> cflg set/unset non-zero a; a=!a; returns a==0;

• lis a, b -> define/redefine a as an alias for b
• buf a -> set buffer idex to a
• sow varargs -> write varargs to current buffer
• reap a -> execute op idex a for current buffer

A lot has changed about Peso in the last few months; most of the workload is now done over at avtomat and in a more refined fashion. As for ESPECTRO, it is now shb7 and not currently under development, though I do have plans for the near future.

For now, I am closing this issue and the associated project just to make sure we don't leave things just 'hanging', m'kay?
