如何计算netbeans项目中的行数

Question

您好我有netbeans 7,我想知道如何计算项目的总行数.我查看了谷歌,但每次我这样做,我只发现死角或非工作插件.有谁知道如何计算线？

Answer 1

您可以使用与7.1 nb-wordcount 一起使用的wordcount .

要配置wordcount,请进入Tools- > Options- > Miscellaneous. 如果您想要除Java和Groovy之外的其他文件,则必须进行更改Accept filename.

要显示计数窗口,请进入Window- > Open WordCount Window.

要显示统计数据,请单击WordCounting(第二个按钮).我将显示所选目录的统计信息Projects (window)(它必须是包或类似源包或网页,如果您选择项目它将无法工作).

此外,如果你在Linux上,你可以简单地执行:

 find . -name '*.java' | xargs wc -l

Answer 2

我知道这是一个非常古老的问题,但是有一种更简单的方法可以在netbeans项目中找到不涉及安装插件的行数:

1. 右键单击要查找行数的文件夹或包.
   注意:不要右键单击项目本身,因为这将导致它计算所有生成的文件中的行.
2. 点击Find或Find in Files或按CtrlF.
3. 确保Match下拉列表设置为Regular Expression.
4. 在\n搜索框中输入.
5. 按查找,项目所包含的行数将显示在
   Search Results选项卡的顶部.

注意:在NetBeans中,搜索在5000个结果后停止,因此如果您的项目比这长,那么此方法将不起作用

我希望得到一个剪切和粘贴的答案.所以我写了一个.

编辑:支持数百万行代码.无需外部库.

public static void main(String[] args) throws FileNotFoundException {

    final String folderPath = "D:\\Dev\\MYPROJECT\\src";

    long totalLineCount = 0;
    final List<File> folderList = new LinkedList<>();
    folderList.add(new File(folderPath));
    while (!folderList.isEmpty()) {
        final File folder = folderList.remove(0);
        if (folder.isDirectory() && folder.exists()) {
            System.out.println("Scanning " + folder.getName());
            final File[] fileList = folder.listFiles();
            for (final File file : fileList) {
                if (file.isDirectory()) {
                    folderList.add(file);
                } else if (file.getName().endsWith(".java")
                        || file.getName().endsWith(".sql")) {
                    long lineCount = 0;
                    final Scanner scanner = new Scanner(file);
                    while (scanner.hasNextLine()) {
                        scanner.nextLine();
                        lineCount++;
                    }
                    totalLineCount += lineCount;
                    final String lineCountString;
                    if (lineCount > 99999) {
                        lineCountString = "" + lineCount;
                    } else {
                        final String temp = ("     " + lineCount);
                        lineCountString = temp.substring(temp.length() - 5);
                    }
                    System.out.println(lineCountString + " lines in " + file.getName());
                }
            }
        }
    }
    System.out.println("Scan Complete: " + totalLineCount + " lines total");
}

结果显示类似于以下内容:
