Hello,
I am still trying to fix issue #7773, after using the git grep command, I managed to navigate and locate the potential problem. Indeed, I found where the error message is assembled then returned to be displayed, it is located in language-tool-core/src/java/.../rules/patterns/PatternRuleMatcher.java after a few tests, I could locate the problem in this fonction :
/**
* Concatenates the matches, and takes care of phrases (including inflection
* using synthesis).
* @param start Position of the element as referenced by match element in the rule.
* @param index The index of the element found in the matching sentence.
* @param tokenIndex The position of the token in the AnalyzedTokenReadings array.
* @param tokens Array of AnalyzedTokenReadings
* @return @String[] Array of concatenated strings
*/
private String[] concatMatches(int start, int index,
int tokenIndex, AnalyzedTokenReadings[] tokens,
int nextTokenPos, List<Match> suggestionMatches)
throws IOException {
String[] finalMatch;
int len = phraseLen(index);
Language language = rule.language;
if (len == 1) {
int skippedTokens = nextTokenPos - tokenIndex;
MatchState matchState = suggestionMatches.get(start).createState(language.getSynthesizer(), tokens, tokenIndex - 1, skippedTokens);
finalMatch = matchState.toFinalString(language);
//System.out.println("concat\n" + finalMatch[0]);
} else {
List<String[]> matchList = new ArrayList<>();
for (int i = 0; i < len; i++) {
int skippedTokens = nextTokenPos - (tokenIndex + i);
MatchState matchState = suggestionMatches.get(start).createState(language.getSynthesizer(), tokens, tokenIndex - 1 + i, skippedTokens);
matchList.add(matchState.toFinalString(language));
}
return combineLists(matchList.toArray(new String[matchList.size()][]),
new String[matchList.size()], 0, language);
}
return finalMatch;
}
More particularly in these lines :
int skippedTokens = nextTokenPos - tokenIndex;
MatchState matchState = suggestionMatches.get(start).createState(language.getSynthesizer(), tokens, tokenIndex - 1, skippedTokens);
finalMatch = matchState.toFinalString(language);
From what I managed to test, everything is fine until we get there, and that’s when difficulties arise. After creating an object MatchState by using the function createState() from Match.java and/or calling toFinalString() from MatchState.java, is when the error message is created incorrectly. So in order to resolve this, I need to investigate these leads but these two classes are quite dense and I am not sure I understand how they process data and then use it to do their jobs properly. Could anyone with experience with these classes help me ?
