Push an outer layer of interpretation functor into each named field.

Split out the query string into a list of keys and values. A few importants points:

• The result returned is still bytestrings, since we perform no character decoding here. Most likely, you will want to use UTF-8 decoding, but this is left to the user of the library.
• Percent decoding errors are ignored. In particular, "%Q" will be output as "%Q".
• It decodes '+' characters to ' '

Same functionality as parseQuery, but with the option to decode '+' characters to ' ' or to preserve any '+' encountered. If you want to replace any '+' with a space, use True.

Parse a QueryText from a ByteString. See parseQuery for details.

queryToQueryText . parseQuery

Parse query param value.

sequentially consistent

Only to be used on header's values which support quality value syntax A few things to keep in mind when using this function: * The resulting Int will be anywhere from 1000 to 0 ("1" = 1000, "0.6" = 600, "0.025" = 25) * The absence of a Q value will result in 'Just 1000' * A bad parse of the Q value will result in a Nothing, e.g. * Q value has more than 3 digits behind the dot * Q value is missing * Q value is higher than 1 * Q value is not a number

Parse query param value in a Maybe.

>>> parseQueryParamMaybe "true" :: Maybe Bool
Just True

Case insensitive. Parse given text case insensitive and then parse the rest of the input using parseQueryParam.

>>> parseQueryParamWithPrefix "z" "z10" :: Either Text Int
Right 10

Parse multiple query parameters.

>>> parseQueryParams ["1", "2", "3"] :: Either Text [Int]
Right [1,2,3]

>>> parseQueryParams ["64", "128", "256"] :: Either Text [Word8]
Left "out of bounds: `256' (should be between 0 and 255)"

Parses a full Accept header into a list of quality-valued media types.

The default sequence of colours to use when plotings different data sets in a graph.

Parse an xsd:all, xsd:choice, or xsd:sequence decl.

Definition:

>>> parSequence modifier = Stream.parMapM modifier id

Useful idioms:

>>> parFromListM = Stream.parSequence id . Stream.fromList

>>> parFromFoldableM = Stream.parSequence id . StreamK.toStream . StreamK.fromFoldable

Parses a query into an intermediate format which is easy to feed to HXT

• The top-level lists represent the top level comma separated queries.
• SelectorGroup is a group of qualifiers which are separated with spaces or > like these three: table.main.odd tr.even > td.big
• A SelectorGroup as a list of Selector items, following the above example the selectors in the group are: table, .main and .odd
