Implementation of interpolated multiline strings that ignores indentation and trailing whitespaces.
It's QuasiQuoter.
Actually it's modification of interpolatedstring-perl6 package. I used it to implemenent my own strings I really like.
This implementation looks just like qc
from interpolatedstring-perl6 package but ignores any indentation,
line-breaks (except explicitly written using \n char)
and trailing whitespaces.
'm' in 'qm' means 'multiline'.
You could write a decoratively formatted string and your decorative indentation and line-breaks wont go to the string, but when you really need it, you could just escape it using backslash.
Simple usage example
{-# LANGUAGE QuasiQuotes #-}
import Text.InterpolatedString.QM (qm)
main :: IO ()
main = putStrLn [qm| hello
\ world |]
More examples
[qm| hello world,
\ what's going on here? |]
-- Result: "hello world, what's going on here?"
[qm|
it's actual
ly ignored
|]
-- Result: "it's actually ignored"
[qm| \ You could explicitly escape indentation or\n
line-breaks when you really need it! \
|]
-- Result: " You could explicitly escape indentation or\nline-breaks when you really need it! "
[qm| {1+2} \{3+4} |]
-- Result: "3 {3+4}"
