使用更少的gdb传呼机 [英] Using less as gdb pager

问题描述

我注意到在GDB中，当发出长输出的命令(如 info变量)时，输出一次显示一页，按 enter 向下并显示 q 退出.

I noticed that in GDB, when issuing commands with long output like info variables, the output is displayed one page at time, pressing enter to go down and q to quit.

是否可以将默认的寻呼机替换为另一个寻呼机，例如 less ，以便我可以上下导航，退出，搜索等?

Is it possible to replace the default pager with another one, such as less, so that I can navigate up and down, quitting, searching, etc?

Is it possible to replace the default pager with another one

否:GDB不会调用外部程序来显示输出，它只是在每屏满时暂停输出(并且您可以使其不按设置高度0 暂停">).

No: GDB doesn't call into external program to display the output, it simply pauses the output every screenfull (and you can make it not pause by set height 0).

除了在 emacs 内部运行外，您还可以使用 screen 或 tmux (了解它们通常会为您提供很多帮助情况)，或要求GDB记录输出(设置登录)，然后使用所需的任何 $ PAGER 在 gdb.txt 中进行搜索.

In addtion to running inside emacs, you could also use screen or tmux (learning them will generally help you in a lot of other situations), or ask GDB to log output (set logging on) and then search in gdb.txt with any $PAGER you want.
