如何使用hypnotoad或morbo调用交互式Perl调试? [英] How can you invoke interactive Perl debugging with hypnotoad or morbo?

问题描述

我不熟悉Mojolicious，但是已经使用Perl一段时间了.我必须克服一些麻烦，但是我可以使交互式Perl调试器(和Komodo)与Apache的远程连接一起工作，但是我找不到关于使用hypnotoad或morbo进行交互式调试的任何东西.

I'm new to mojolicious but have been using Perl for some time. I have to jump through some hoops but I can get the interactive Perl debugger (and Komodo) working with remote connections for Apache but I can't find anything about interactive debugging with hypnotoad or morbo.

http://mojolicio.us/perldoc/Mojolicious/上的基础教程中的命令行示例Guides/Tutorial#Hello-World 可以正常运行，因为您可以使用perl -d启动它们，但是无论如何我都看不到告诉hypnotoadctl脚本将服务置于交互式调试模式ala apache.

The command line examples in the basic tutorial on http://mojolicio.us/perldoc/Mojolicious/Guides/Tutorial#Hello-World work fine because you can launch them with perl -d, but I don't see anyway to tell the hypnotoadctl script to put the service in interactive debug mode ala apache.

这不可能吗?提示?尖端?指针?

Is this not possible? Hints? Tips? Pointers?

推荐答案

morbo和hypnotoad是perl程序，因此可以使用-d开关启动它们.

morbo and hypnotoad are perl programs, so you can launch them with the -d switch.

perl -d $(which morbo) myMojoApp.pl

在您的应用程序周围散布一堆$DB::single = 1语句可能是最简单的，您希望在其中放置初始断点并以c作为第一个调试器命令运行.当您运行遇到断点的请求时，您将在启动morbo的终端中看到调试器提示.

It's probably easiest to sprinkle a bunch of $DB::single = 1 statements around you app where you want your initial breakpoints to go and run c as the first debugger command. When you run a request that hits a breakpoint, you'll get a debugger prompt in the terminal that launched morbo.

hypnotoad与调试器一起使用将更加棘手，因为它会快速关闭所有标准文件句柄，多次调用fork并成为守护程序.

hypnotoad will be trickier to use with the debugger because it quickly closes all the standard filehandles, calls fork several times, and becomes a daemon.
