citeproc-hs-0.3.8: A Citation Style Language implementation in Haskell

Safe HaskellNone



This module provides functions for processing the evaluated Output for citation disambiguation.

Describe the disambiguation process.



disambCitations :: Style -> [Reference] -> Citations -> [CitationGroup] -> ([(String, String)], [CitationGroup])Source

Given the Style, the list of references and the citation groups, disambiguate citations according to the style options.

reEvaluate :: Style -> [CiteData] -> [(Cite, Reference)] -> CitationGroup -> CitationGroupSource

Evaluate again a citation group with the EvalState disamb field set to True (for matching the "disambiguate" condition).

hasIfDis :: IfThen -> [Bool]Source

Check if the Style has any conditional for disambiguation. In this case the conditional will be try after all other disambiguation strategies have failed. To be used with the generic query function.

getCitDisambOptions :: Style -> [String]Source

Get the list of disambiguation options set in the Style for citations.

getDuplCiteData :: Bool -> Bool -> [CitationGroup] -> [[CiteData]]Source

Group citation data (with possible alternative names) of citations which have a duplicate (same collision, and same citYear if year suffix disambiiguation is used). If the first Bool is False, then we need to retrieve data for year suffix disambiguation. The second Bool is True when comparing both year and contributors' names for finding duplicates (when the year-suffix option is set).

getCiteData :: Output -> [CiteData]Source

For an evaluated citation get its CiteData. The disambiguated citation and the year fields are empty. Only the first list of contributors' disambiguation data are collected for disambiguation purposes.

disambiguate :: Eq a => [[a]] -> [[a]]Source

Try to disambiguate a list of lists by returning the first non colliding element, if any, of each list:

 disambiguate [[1,2],[1,3],[2]] = [[2],[3],[2]]

same :: Eq a => [a] -> [Bool]Source

For each element a list of Bool: True if the element has a duplicate in the list:

 same [1,2,1] = [True,False,True]

hasDuplicates :: Eq a => [a] -> BoolSource

allTheSame :: Eq a => [a] -> BoolSource
