這是一項相當艱鉅的任務:-)
它由您正在使用的完成程序處理。完成者的complete()
方法只能用於搜索最後一個空白後的內容。
如果你在圖書館的FileNameCompleter
尋找例如:未進行此操作可言,所以你會發現沒有完成,因爲<input1> <input2>
完成者搜索,不僅爲<input2>
:-)
你會必須自己實現一個能夠找到input2的完成者。
此外,CompletionHandler
必須將您發現的內容附加到您已輸入的內容上。
這是一個基本的實現更改默認FileNameCompleter
:
protected int matchFiles(final String buffer, final String translated, final File[] files,
final List<CharSequence> candidates) {
// THIS IS NEW
String[] allWords = translated.split(" ");
String lastWord = allWords[allWords.length - 1];
// the lastWord is used when searching the files now
// ---
if (files == null) {
return -1;
}
int matches = 0;
// first pass: just count the matches
for (File file : files) {
if (file.getAbsolutePath().startsWith(lastWord)) {
matches++;
}
}
for (File file : files) {
if (file.getAbsolutePath().startsWith(lastWord)) {
CharSequence name = file.getName() + (matches == 1 && file.isDirectory() ? this.separator() : " ");
candidates.add(this.render(file, name).toString());
}
}
final int index = buffer.lastIndexOf(this.separator());
return index + this.separator().length();
}
而這裏CompletionHandler
的complete()
- 方法更改默認CandidateListCompletionHandler
:
@Override
public boolean complete(final ConsoleReader reader, final List<CharSequence> candidates, final int pos)
throws IOException {
CursorBuffer buf = reader.getCursorBuffer();
// THIS IS NEW
String[] allWords = buf.toString().split(" ");
String firstWords = "";
if (allWords.length > 1) {
for (int i = 0; i < allWords.length - 1; i++) {
firstWords += allWords[i] + " ";
}
}
//-----
// if there is only one completion, then fill in the buffer
if (candidates.size() == 1) {
String value = Ansi.stripAnsi(candidates.get(0).toString());
if (buf.cursor == buf.buffer.length() && this.printSpaceAfterFullCompletion && !value.endsWith(" ")) {
value += " ";
}
// fail if the only candidate is the same as the current buffer
if (value.equals(buf.toString())) {
return false;
}
CandidateListCompletionHandler.setBuffer(reader, firstWords + " " + value, pos);
return true;
} else if (candidates.size() > 1) {
String value = this.getUnambiguousCompletions(candidates);
CandidateListCompletionHandler.setBuffer(reader, value, pos);
}
CandidateListCompletionHandler.printCandidates(reader, candidates);
// redraw the current console buffer
reader.drawLine();
return true;
}
嗯,。所以這需要比我想象的更大的改變。感謝您的洞察! – flakes
至少它似乎無法通過某些配置激活它。但是你可以制定一個標準的實現併爲你的下一個類繼承它。 –
