我可以在gdb中更改RET的绑定吗? [英] Can I change the binding of RET in gdb?

问题描述

我想在输入回车符重复执行最后输入的命令时禁用gdb行为.我只希望它什么也不做.这可能吗?

I'd like to disable the gdb behavior where typing a carriage return repeats execution of the last command entered. I'd just like it to do nothing. Is this possible?

推荐答案

似乎重复大多数命令是gdb的默认行为，并且没有设置可以更改它.这就是它在gdb的源代码中的样子:

It seems that repeating most commmands is a default gdb's behavior and there is no setting to change it. This is how it looks in gdb's source:

/* Handle a complete line of input.  This is called by the callback
   mechanism within the readline library.  Deal with incomplete
   commands as well, by saving the partial input in a global
   buffer.  */

static void
command_line_handler (char *rl)
{
 ...
  int repeat = (instream == stdin);

因此您可以看到，如果instream是STDIN，则将repeat分配为1.没有其他方法可以为repeat分配不同的值.

So as you can see repeat is assigned 1 if instream is STDIN. There is no other way to assign repeat a different value.

因此，您可以做的是从gdb的源代码在计算机上构建自己的gdb可执行文件(

So what you can do is to build your own gdb executable on your machine from gdb`s source (http://ftp.gnu.org/gnu/gdb/). But before building change a little the line 591 in gdb/event-top.c. Instead of

int repeat = (instream == stdin);

写

int repeat = 0;
