This is the first pass at displaying values for intermediate function calls. The function added to Main.hs should result in this UI:

Source

g :: forall a . Integral a => a -> a -> Double
g x y =    
   let least = lcm x y
   in fromIntegral least ^^ gcd x y

Variables

• $arg1 = 6
• $arg2 = 15
• $result = 27000.0
• fromIntegral = 30.0
• _gcd = \
• _gcd' = 3
• _lcm = \
• _lcm' = 30
• least = 30
• x = 6
• y = 15

I disabled infix function handling for this PR, I realized I have to do some substitution to create legal variable names for some of the operator functions.

The couple of tests I added should be automated hspec, etc. tests, but I left them as just 'prints' for now to avoid breaking your build.

I should say more generally that it looks quite plausible, thanks a lot. I've got the flu right now so not in a detail state of mind but will get to it soon.

Ok, feel better.

Thanks - looks good!
