GDB：如何添加一个运行命令的组合键？ [英] GDB: How to add a key combination which runs a command?

问题描述

我使用 -tui 模式使用 GNU gdb（GDB）7.10.1 。我想为命令 up 和 down 添加一个组合键。对于向上和 Ctrl + d kbd> for down 。

I'm using GNU gdb (GDB) 7.10.1 with the -tui mode. I would like to add a key combination for the commands up and down. Something like Ctrl+u for up and Ctrl+d for down.

我只看过readline的评论，但没有解释如何整合gdb init文件中的组合。任何想法？

I've seen only comments about readline but not an example explaining how to integrate the combination in the gdb init file. Any idea?

推荐答案

我不是TUI用户，但我的理解是TUI有两种模式。

I am not a TUI user, but my understanding is that the TUI has two modes.

在其初始（普通）模式下，它使用readline，如普通的gdb CLI。 Readline提供了重新绑定密钥的方法

In its initial (normal) mode, it uses readline like the ordinary gdb CLI. Readline provides a way to rebind keys via ~/.inputrc. The main thing you need to know here is that gdb is, sensibly enough, called "gdb" for readline's purposes. So a binding might look like:

$if gdb
"\C-u": "up\n"
$endif

TUI还有一个单键模式。据我所知，这种模式不使用readline，也没有办法重新绑定密钥。但是，在这种模式下，u和d已经按照你喜欢的方式绑定了。

The TUI also has a "single key" mode. As far as I know, this mode doesn't use readline and there is no way to rebind keys. However, in this mode, "u" and "d" are already bound the way you'd like.
