代码补全中变量只有1个字符会存在问题

[liukonghe]

无法出现a变量的补全。
查看源码后我发现问题在于ext-language_tools.js
function wordDistance(doc, pos) {
var prefixPos = getWordIndex(doc, pos);
var words = doc.getValue().split(splitRegex);
var wordScores = Object.create(null);

var currentWord = words[prefixPos];

words.forEach(function(word, idx) {
    if (!word || idx === words.length-1) return;

    var distance = Math.abs(prefixPos - idx);
    var score = words.length - distance;
    if (wordScores[word]) {
        wordScores[word] = Math.max(score, wordScores[word]);
    } else {
        wordScores[word] = score;
    }
});
return wordScores;

}
我将 if (!word || word === currentWord) return;代码更改为if (!word || idx === words.length-1) return;
现在变量只有1个字符的补全就没问题了
