nowdoc

Package nowdoc contain 3 QuasiQuotes.

• nowdoc: Simplest here document with only two transformation.
• txtfile: It incerts text file contents as string.
• binfile: It incerts binary file contents as string.

QuasiQuoter nowdoc

Simplest here document. Only two transformation.

• remove head newline if exist
• remove one space from '|', space, space, ..., ']'

short examples

hello = [nowdoc|
abc
def
ghi
|]

is

hello = "abc\ndef\nghi\n"

,

hello = [nowdoc|hello|]

is

hello = "hello"

and

hello = [nowdoc|
hello | ]
world |  ]
! |   ]
|]

is

hello = "hello |]\nworld| ]\n! |  ]"

QuasiQuoter txtfile

It incerts file contents as string without transformation. It read file as text file (with default encoding on your system).

main :: IO ()
main = putStr [txtfile|foo.txt|]

QuasiQuoter binfile

It incerts file contents as string without transformation. It read file as binary file.

main :: IO ()
main = print [binfile|foo.dat|]
