Description copied from interface: CompletionMatcher

Compiles completion matcher functions

Specified by:

compile in interface CompletionMatcher

Parameters:

options - LineReader options

prefix - invoked by complete-prefix or expand-or-complete-prefix widget

line - The parsed line within which completion has been requested

caseInsensitive - if completion is case insensitive or not

errors - number of errors accepted in matching

originalGroupName - value of JLineReader variable original-group-name

matches

public List<Candidate> matches(List<Candidate> candidates)

Specified by:

matches in interface CompletionMatcher

Parameters:

candidates - list of candidates

Returns:

a map of candidates that completion matcher matches

exactMatch

public Candidate exactMatch()

Specified by:

exactMatch in interface CompletionMatcher

Returns:

a candidate that have exact match, null if no exact match found

getCommonPrefix

public String getCommonPrefix()

Specified by:

getCommonPrefix in interface CompletionMatcher

Returns:

a common prefix of matched candidates
