Convenient template Haskell quasiquoters to format strings.
Synopsis
- str :: QuasiQuoter
Documentation
str :: QuasiQuoter Source #
A QuasiQuoter that treats the input as a string literal:
>>>
[str|x|]
"x"
Any #{symbol}
is replaced by the value of the Haskell symbol symbol
which is in scope:
>>>
x = "hello"
>>>
[str|#{x} world!|]
"hello world!"
##
means a literal #
without the special meaning for referencing
haskell symbols:
>>>
[str|##{x} world!|]
"#{x} world!"
A #
at the end of line means the line continues to the next line without
introducing a newline character:
>>>
:{
[str|hello# world!|] :} "hello world!"
Bugs: because of a bug in parsers, a lone # at the end of input gets removed.
