an arithmetic calculator written with compiling theory in mind

• This repo is intended to be a follow-up practice after watching Mr. Landwerth's building a complier tutorial (see the link below) and refresh my knowledge of compiling theory back in the school.
• This repo is not a line-to-line replica to Mr. Landwerth's Minsk Complier (written in C# with OO design).
• I try to write everything from scratch. (might change my mind later :-0 )
• I hope eventualycalculator can be a full fledged complier targeting WebAssembly.

command list:

:context:enableAST:disableAST:help:quit

For nowcalculator supports:

• basic arithmetic computation with parentheses
• if expression
• assignments & variables
• type check

You can check out all the test cases undertest/Spec.hs
