Scotty action
addPathNormalizer :: ScottyM () Source #
Adds a Scotty route that matches all non-normalized paths, where the action redirects to the corresponding normalized path.
pathNormalizerAction :: ActionM () Source #
A Scotty action which issues a redirect to the normalized
form of the request target, or aborts (with next) if the
request target is already a normal path.

normalizePath :: Text -> NormalizationResult Text Source #
A path that's already in normal form:
>>>normalizePath "/one/two/three"AlreadyNormal
A path that contains empty segments:
>>>normalizePath "//one/./two/three/"Normalized "/one/two/three"
A path that goes "up" a directory:
>>>normalizePath "/one/two/three/../four"Normalized "/one/two/four"
A path that goes up too far:
>>>normalizePath "/one/../../two/three"Invalid
The root path is a normalized path:
>>>normalizePath "/"AlreadyNormal
The empty string is not a valid path (because a path must begin with a slash):
>>>normalizePath ""Invalid
normalizeSegmentList :: [Text] -> NormalizationResult [Text] Source #
A path that's already in normal form:
>>>normalizeSegmentList ["one", "two", "three"]AlreadyNormal
A path that contains empty segments:
>>>normalizeSegmentList ["", "one", ".", "two", "three"]Normalized ["one","two","three"]
A path that goes "up" a directory:
>>>normalizeSegmentList ["one", "two", "three", "..", "four"]Normalized ["one","two","four"]
A path that goes up too far:
>>>normalizeSegmentList ["one", "..", "..", "two", "three"]Invalid
The empty string is a normalized path:
>>>normalizeSegmentList []AlreadyNormal
