统计某个目录下代码行数

写了个控制台程序，可以统计某个目录下，Qt项目的C++代码行数

#include <QDebug>
#include <QCoreApplication>
#include <QDir>
#include <QFileInfoList>
#include <QFile>
#include <QTextStream>

int countLines(const QString& filePath) {
    if(filePath.contains("moc_") || filePath.contains("ui_"))
        return 0;
    QFile file(filePath);
    if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return 0;
    QTextStream in(&file);
    int lineCount = 0;
    while (!in.atEnd()) {
        QString line = in.readLine();
        if (!line.trimmed().isEmpty()) // 忽略空行
            lineCount++;
    }
    return lineCount;
}

void processDirectory(const QDir& directory, int& totalLines) {
    QFileInfoList fileList = directory.entryInfoList(QStringList() << "*.cpp" << "*.h", QDir::Files);
    foreach (const QFileInfo& fileInfo, fileList) {
        int lines = countLines(fileInfo.filePath());
        totalLines += lines;
        qDebug() << fileInfo.fileName() << ": " << lines;
    }
    QFileInfoList subDirList = directory.entryInfoList(QDir::Dirs | QDir::NoDotAndDotDot);
    foreach (const QFileInfo& subDirInfo, subDirList) {
        QDir subDir(subDirInfo.filePath());
        processDirectory(subDir, totalLines);
    }
}

int main(int argc, char *argv[]) {
    QCoreApplication a(argc, argv);
    QString directoryPath = "D:/truck/XXX"; // 替换为你要统计的目录路径
    QDir directory(directoryPath);
    int totalLines = 0;
    processDirectory(directory, totalLines);
    qDebug() << "Total lines: " << totalLines;
    return a.exec();
}
