我从GNU getline文档中读到,它能够将一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 键。
但是如何使用它将某些动作绑定到以下键?: CTRL + TAB , ESC , PAUSE / BREAK
答案 0 :(得分:3)
#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> ");
}
}
如果您正在运行GNU系统(或其中一个变体),请运行:
info readline "command line editing" "introduction" # notation convention
info readline "programming" "readline" "biding" # biding functions
