- computeFreeNames :: Data a => a -> FreeNames
- getModuleAsserts :: Module a -> [LAssertDecl]
- setNodeIdsZero :: Data a => a -> a

# Documentation

removeSourceLocations :: Data a => a -> aSource

`removeSourceLocations`

sets all locationsInfos to `NoLocation`

removeParens :: Data a => a -> aSource

`removeParens`

removes all occurences of of Parens,
i.e. explicit parentheses from the AST

removeModuleAsserts :: Module a -> Module aSource

Remove assert declarations from a module.

unUniqueIdent :: Data a => a -> aSource

unUniqueIdent replaces the all UIdent with the Ident of the the new name, thus forgetting additional information like the bindingside, etc. Usefull to get a smaller AST.

computeFreeNames :: Data a => a -> FreeNamesSource

Compute the FreeNames of an Expression. This function does only work after renaming has been done. This implementation is inefficient.

getModuleAsserts :: Module a -> [LAssertDecl]Source

Get the assert declarations of a module.

setNodeIdsZero :: Data a => a -> aSource

Set all NodeIds to zero.
