Checking
acceptsepsilon :: IsParser p s => p v -> Bool Source #
Checks if the parser accepts epsilon.
Prelude defs
opt :: IsParser p s => p a -> a -> p a infixl 2 Source #
Optionally recognize parser p.
If p can be recognized, the return value of p is used. Otherwise,
the value v is used. Note that opt is greedy, if you do not want
this use ... | pSucceed v instead. Furthermore, p should not
recognise the empty string.
Sequential compositions
(<+>) :: IsParser p s => p a -> p b -> p (a, b) infixl 4 Source #
Parses the sequence of pa and pb, and combines them as a tuple.
(<**>) :: Applicative f => f a -> f (a -> b) -> f b infixl 4 #
A variant of <*> with the arguments reversed.
pPacked :: IsParser p s => p a -> p b1 -> p b -> p b Source #
This can be used to parse x surrounded by l and r.
Example:
pParens = pPacked pOParen pCParen
