alexeevg / ipprint Goto Github PK

I'm using the numbers package in GHCI, and the output precision can be truncated when it passes through the parser. An example (without ipprint):

Prelude> import Data.Number.BigFloat
Prelude Data.Number.BigFloat> 0 :: BigFloat Prec50
0.00000000000000000000000000000000000000000000000000e0

I think the problem is that we can use this output to assign to a non-big float. That is,

Prelude> let x = 0.123456789012345678901234567890e0
Prelude> x
0.12345678901234568

Maybe there's something that can be done when precision of a number is greater than that of the default? For comparison, with ipprint,

λ. import Data.Number.BigFloat
λ. let x = 0.123456789012345678901234567890e0
λ. x
    0.12345678901234568

λ> IPPrint.pshow 2
    "    2"
it :: String
λ> "hello"
    "hello"
it :: [Char]

I noticed that pshow adds 4 spaces in front of the value, i'm used to the value being aligned to the left of the terminal. Is there any way to not have it print with 4 spaces in front of the value?
