# Documentation

newtype XName

An XName just holds the original XSD qualified name. It does not ensure that the string conforms to any rules of the various Haskell namespaces. Use a NameConverter to define how you would like names to be mangled.

Constructors

XName QName |

Instances

Eq XName |
Show XName |

newtype HName

An HName is a resolved version of an XName. It should conform to the various namespace rules, and may already include a module qualifier if appropriate.

Constructors

HName String |

Instances

Show HName |

data NameConverter

A NameConverter is a collection of functions that convert an XName into an HName, for various Haskell namespaces. You can define your own arbitrary resolver, but should ensure that you abide by the Haskell rules for conid, varid, etc.

Fields

modid :: XName -> HName
conid :: XName -> HName
varid :: XName -> HName
unqconid :: XName -> HName
unqvarid :: XName -> HName
fwdconid :: XName -> HName

  for forward type decls

fieldid :: XName -> XName -> HName

simpleNameConverter :: NameConverter

A simple default set of rules for resolving XNames into HNames.

avoidKeywords :: String -> String

Ensure that a string does not match a Haskell keyword.

fpml :: String -> String

A specialised module-name converter for FpML module names with multiple dashes, including version numbers, e.g. fpml-dividend-swaps-4-7.xsd becomes FpML.V47.Swaps.Dividend but fpml-posttrade-execution-4-7.xsd becomes FpML.V47.PostTrade.Execution

wordsBy :: (a -> Bool) -> [a] -> [[a]]

Chop a list into segments, at separators identified by the predicate. The separator items are discarded.

basename :: String -> String -> String

Remove any prefix directory names, and given suffix extension.
