逃离嵌套的try - catch语句 [英] Escape from nested try - catch statement

问题描述

我现在可以使用 dbstop 命令，但每次看代码并想停止运行程序时，我必须为每个嵌套级别输入一次 dbquit 。

这是非常烦人的，我正在寻找一个解决方案，一旦完成调试，真的停止调试所有程序。

这是一个例如我如何调用代码：

  dbstop if error 
 dbstop if catch error 
 mytestmain 
  

这里是一个例子，该函数可以是什么样的（子功能可能是也可能不是在一个不同的.m文件）

  function mytestmain 
 try 
 mytestsub 
 catch 
 end 
 
 %%子函数的定义
函数mytestsub 
 try 
a = b;％生成错误b没有定义
 catch 
 end 
  

< hr>

我尝试了什么？

• 我尝试使用一个脚本或一个调用的函数 dbquit 两次，但这只会执行 dbquit 一次。


• 使用 dbquit（'all'），但不起作用

---

请注意，我不想删除代码中的try-catch语句。

解决方案

在使用 dbquit

dbclear > dbclear all; dbquit;


但是，请注意，这也将清除您手动设置的所有断点，因此，如果使用断点此外，您应该使用

  dbclear如果错误; dbclear如果捕获错误; dbquit; 
  

I am currently debugging code with nested try-catch statements.

I can easily handle the errors with the dbstop command, but each time I look at the code and want to stop running the program, I have to enter dbquit once for each nesting level.

As this is quite annoying I am looking for a solution to really stop debugging all programs once I am done debugging.

Here is an example of how I call the code:

dbstop if error
dbstop if caught error
mytestmain

And here is an example of what the function could look like (the subfunction may or may not be in a different .m file)

function mytestmain 
try
    mytestsub
catch
end

%% Definition of subfunction
function mytestsub
try
    a=b;%generate an error as b is not defined
catch
end

What have I tried?

• I tried using a script or a function that calls dbquit twice, however this will only execute dbquit once.
• I tried using dbquit('all'), but with no effect

---

Note that I prefer not to remove the try-catch statements in the code.

解决方案

You could call dbclear before using dbquit

dbclear all; dbquit;

Note, however, that this will also clear all breakpoints you set manually, hence, if you use breakpoints in addition, you should rather use

dbclear if error; dbclear if caught error; dbquit;
