Text parsing tool developed by Qt

Packet Analysis Tool

Function introduction

Support for custom import files
modify keywords
Multi-threaded parsing of text
Save the parsed text to a new file
Open file save folder with one click

The core function related code is as follows:

custom import file

bool MainWindow::openLogFile()
{
    //文本导入框
    QString strPath = QFileDialog::getOpenFileName(NULL,QString::fromUtf8("选择文件"),"",QObject::tr("All(*.*)"));

    if(strPath == "")
    {
        QMessageBox::information(this,QString::fromUtf8("提示"),QString::fromUtf8("选择文件失败，无路径"),"OK");
        return false;
    }
    filePathName = strPath;
    ui->lab_filePath->setText(strPath);
    return true;
}

text file save

void MainWindow::saveRes2File()
{
	QString filePath = QFileDialog::getSaveFileName(NULL,QString::fromUtf8("选择文件"),"",QObject::tr("txt(*.txt)"));

    if(filePath == "")
    {
        QMessageBox::information(this,QString::fromUtf8("提示"),QString::fromUtf8("选择文件失败，无路径"),"OK");
        return false;
    }

	QFile outResFile;
    outResFile.setFileName(filePath);
    if(!outResFile.exists())
    {
        outResFile.open(QIODevice::WriteOnly);
        outResFile.close();
    }
    outResFile.open(QIODevice::ReadWrite | QIODevice::Truncate);

    QString messCount = QString("This parsing omci Count is: " + QString::number(parsCount) + "\n");
    QTextStream outRes(&outResFile);
    if(outResFile.isOpen()) {
        outResFile.write(messCount.toUtf8());
        outRes << ui->out_text->toPlainText();
        outRes.flush();
    }
    outResFile.close();
}

keyword filtering

This project uses QString.indexof() and QString.mid for keyword positioning and text analysis, mainly for sharing, mainly to provide ideas for everyone

void MainWindow::parsOmci(QString goalMes)
{
    //解析目标报文
    bool toHex = true;
    int attrIndex = 0;
    //时间戳
    TimeValue = goalMes.mid(1, goalMes.indexOf(':') - 1);

    //crc结果
    if( goalMes.mid(crcokIndex, 2) == "no")
    {
        Crc_ok = "no";
    }else{
        Crc_ok = "yes";
    }

    //packet_size
    Packet_size = goalMes.mid(packetsizeIndex, packSizeLen);

    }else{

        Omci_trailer = goalMes.right(18).left(16);
    }

    for (int strIndex = 2; strIndex < Omci_trailer.size(); strIndex += 3) {
        Omci_trailer.insert(strIndex, ' ');
    }

    //message content
    attrIndex = bufferIndex + TRANSIDLEN + MESSAGETYPELEN + DEVICEIDTYPELEN + CLASSNOLEN + INSTANCEIDLEN;

    }

    for (int messCount = 0; messCount < insertCount-1; messCount++) {
