GNU readline和键绑定

Question

我从GNU getline文档中读到它能够将某些回调函数绑定到某些键。我已经知道如何使用rl_bind_key函数将动作绑定到TAB密钥。

但我怎么可以用它来绑定一些动作以下键？： CTRL + TAB ，ESC，暂停/BREAK

Answer 1

#include <stdio.h> 

#include <readline/readline.h> 

int my_cool_readline_func (int count, int key) { 
    printf ("key pressed: %d\n", key); 
    rl_on_new_line(); 
    return 0; 
} 

int main(void) { 
    rl_command_func_t my_cool_readline_func; 
    rl_bind_key ('\t', my_cool_readline_func); 
    rl_bind_key (27, my_cool_readline_func); /* ascii code for ESC */ 
    rl_bind_keyseq ("\\C-a", my_cool_readline_func); 

    while (1) { 
     char *line = readline ("rl> "); 
    } 
} 

如果是运行GNU系统（或其一个变体）然后运行：

info readline "command line editing" "introduction" # notation convention 
info readline "programming" "readline" "biding" # biding functions
