Simon Forman b76213ff7e Expression is a list-of-lists now. 
That way we don't have to concatinate quotes onto it all the time.
Instead we amortize in the next_term() function.

Simon Forman 3ae0e5b3a6 Interpret symbols. 
C has function pointers, we can put them in the Gperf wordlist, this
makes the interpreter really simple.  No need for a dictionary (yet).

Implementing the basis functions will be a bit of a slog, and
I still have to implement definitions, but this is starting to shape up
nicely.

Simon Forman 4be1cc5767 Use gperf to save memory. 
We check terms to see if they're in the wordlist, if they are we reuse
the string from the wordlist instead of allocating a new one.

(I've always wanted to use Gperf so I'm pretty stoked about this!)

Simon Forman 74f936efa0 Cleanup and refactoring. 
Bug when subtracting identical numbers.  It gives

    [false 0]

When it should be

or better yet

    [true]

eh?
 2022-10-15 11:05:17 -07:00
Simon Forman 062b01da55 That seems to work: addition and subtraction. 2022-10-15 09:52:58 -07:00

Whew!  Think slow and steady FTW.  Don't get ahead of yourself.  Put the
non-recursive parts in the non-recursive branch, duh.

This is getting out of hand.

Simon Forman 70ea2c3f53 Divmod, yeah? 2022-10-05 08:27:01 -07:00
Simon Forman e2f8d236cc Minor cleanup. 
I almost can't believe I did it.  I guess I thought it would be harder
or more involved.  Maybe divmod will be a pill?

Kinda relaxing after wasting the weekend nerd-sniped by curses.

Simon Forman beafe3aff0 Minor cleanup; multiplication. 
I forgot to commit after cleanup but before implementing multiplication
so this commit is kind of a mess.

Anyway, it works.  :D

Simon Forman f0b6f4036a BitInt start; unittest. 2022-10-04 11:20:14 -07:00
Simon Forman 53bea5f59b That was easy... 
but it breaks associativity or is it commutivity?

Anyway you can't add THREE or more things in one expression (yet)
because adding OberonInt objects returns a two-tuple.

I could adjust the semantics of ObInt to accept such two-tuples and do
add_with_carry() but that's probably more trouble than it's worth.

Just gotta be careful with math expressions, eh?
 2022-10-04 08:53:32 -07:00
Simon Forman 690f157ac8 Switch to double-underscore method names. 
Worry about type conversions later.
