Text.Parsec.IndentParsec.Combinator

Module containing combinators to parse some indentation based structures.

Documentation

blockOf :: (Monad m, Show t, Stream s (IndentT HaskellLike m) t) => IndentParsecT s u m a -> IndentParsecT s u m a

run a given parser inside a block.

foldedLinesOf :: (Monad m, Show t, Stream s (IndentT HaskellLike m) t) => IndentParsecT s u m a -> IndentParsecT s u m a

run a given parser inside a line fold.

between

Arguments

:: (Monad m, Indentation i, Show t, Show i, Stream s (IndentT i m) t)

=> GenIndentParsecT i s u m open

the opening delimiter

-> GenIndentParsecT i s u m close

the closing delimiter

-> GenIndentParsecT i s u m a

the contents

-> GenIndentParsecT i s u m a

Similar to Text.Parsec.Combinator.between. However, the Text.Parsec.Combinator.between will not work as expected because it will not turn off the indentation check of its input parser.

So something like

 whereClause = between lbrack rbrack bindings
 lbrack = do char '{'; spaces
 rbrack = do char '}'; spaces

will not be able to parse say

    where {
 a = 10
 }

Use the version exported by this module instead.

betweenBlock

Arguments

:: (Monad m, Stream s (IndentT HaskellLike m) t, Show t)

=> IndentParsecT s u m open

opening delimitor

-> IndentParsecT s u m close

closing delimitor

-> IndentParsecT s u m a

the contents parser

-> IndentParsecT s u m a

Similar to between but if the opening and closing delimiters are not given, uses a block to delimit the nesting. For example, a haskell where clause will look like

 whereClause = betweenBlock lbrack rbrack bindings
 lbrack = do char '{'; spaces
 rbrack = do char '}'; spaces
