在调试器中传递参数到perl文件，并在系统执行的文件中设置断点

问题描述：

所以我使用perl -d file.pl在perl调试器中运行一个文件。但是，file.pl应该也是参数。如何为file.pl
提供参数还有一个问题：file.pl中有这行：

So I run a file in the perl debugger using perl -d file.pl. But then the file.pl is supposed to take arguments also. How do I supply arguments to the file.pl One more question: file.pl has this line in it:

system("./file2.pl");

有没有办法在file2.pl中设置断点，如果它以系统？我在perl调试器上花费了7天时间，我无法在file2.pl设置断点请帮助

Is there a way to set a breakpoint in file2.pl if it is running as system? I have spent 7 days on perl debugger and I am not able to set a breakpoint at file2.pl Please help

编辑：从DVK获得一个令人敬畏的响应添加DB：：单= 1。我测试了一些文件，它的工作。但是我有超过100个文件，如果我手动这样做，这将需要很多时间。我使用.perldb并使用afterinit来打开所有命令。我已经建立了一个算法，找到断点需要去的每个文件的行号。我无法随机（自动使用可执行文件）打开所有这些文件，并将DB :: single = 1添加到我喜欢的地方。整个系统可能会崩溃。我想设置断点，因为它更安全

Got an awesome response from DVK to add DB::single=1. I tested that on some files and it worked. But I have more than a 100 files and if I do this manually, it will take me a lot of time. I use .perldb and use afterinit to typeahead all commands. I have put in place an algorithm which finds the line number of each file where the breakpoint needs to go. I just can't randomly (automatically using an executable) open all those files and add DB::single=1 to where I like. The whole system can crash then. I want to set breakpoint as it more secure

答

是的，你可以。

将以下代码添加到您想在 file2.pl 中打破的行：

Add the following code to the line where you want to break in file2.pl:

$DB::single = 1;

为了自动控制调试，您需要操作 @DB :: typahead 数组。从 perldoc ：

To control the debugging automatically from that point, you need to manipulate @DB::typeahead array. From perldoc:

您可以通过向@DB :: typeahead添加任意命令来模拟TTY输入到调试器。例如，.perldb文件可能包含：

You can mock TTY input to debugger by adding arbitrary commands to @DB::typeahead. For example, your .perldb file might contain:

   sub afterinit { push @DB::typeahead, "b 4", "b 6"; }

此代码可以是 BEGIN {} 阻止，或特殊 .perldb 配置文件。

This code can be either in a BEGIN {} block, or a special .perldb config file.
