Example 1 with PrefixMatcher

use of com.intellij.codeInsight.completion.PrefixMatcher in project intellij-community by JetBrains.

the class LookupTypedHandler method completeTillTypedCharOccurrence.

private static boolean completeTillTypedCharOccurrence(char charTyped, LookupImpl lookup, LookupElement item) {
    PrefixMatcher matcher = lookup.itemMatcher(item);
    final String oldPrefix = matcher.getPrefix() + lookup.getAdditionalPrefix();
    PrefixMatcher expanded = matcher.cloneWithPrefix(oldPrefix + charTyped);
    if (expanded.prefixMatches(item)) {
        for (String s : item.getAllLookupStrings()) {
            if (matcher.prefixMatches(s)) {
                int i = -1;
                while (true) {
                    i = s.indexOf(charTyped, i + 1);
                    if (i < 0)
                        break;
                    final String newPrefix = s.substring(0, i + 1);
                    if (expanded.prefixMatches(newPrefix)) {
                        lookup.replacePrefix(oldPrefix, newPrefix);
                        return true;
                    }
                }

    for (LookupElement item : myItems) {
        if (item.isValid()) {
