statement logic !!!

see lib/Logic/readme.md for more details about what's here

requirements

• a haskell compiler e.g. GHC
• cabal the haskell build system if you want
• containers this is the one package i depend on and i'm using cabal to handle it properly, i apologize in advance

compile it

make

or look in Makefile

or

cabal build

I guess...

usage

only this kind of this has been implemented in the main function so far:

echo '((p->q)<->(!q->!p))' | ./logic

output

Iff (Implies (Atom "p") (Atom "q")) (Implies (Not (Atom "q")) (Not (Atom "p")))
