'''GNU Readline'''是一个[[函式庫|软件库]]，可为具有[[命令行界面]]（例如[[Bash]]）的[[互动式计算|交互式程序]]提供[[行编辑器]]和历史记录功能。是[[GNU計劃]]的一部分，目前由Chet Ramey维护。

用户可以移动文本[[游標|光标]]，搜索[[命令行历史记录|命令历史]]，控制[[剪下、複製、貼上|kill ring]]（一个更灵活的剪贴板），并在[[終端|文本终端]]上使用Tab键自动完成。作为一个[[跨平臺]]的库，readline允许不同系统上的应用程序展现相同的行编辑行为。

== 示例代码 ==
下面的代码是[[C语言]]的，必须通过向编译器传递<tt>-lreadline</tt>标志来链接到readline库：

<syntaxhighlight lang="cpp">
#include <stdlib.h>
#include <stdio.h>
#include <readline/readline.h>
#include <readline/history.h>

int main()
{
// Configure readline to auto-complete paths when the tab key is hit.
rl_bind_key('\t', rl_complete);

while (1) {
// Display prompt and read input
char* input = readline("prompt> ");

// Check for EOF.
if (!input)
break;

// Add input to readline history.
add_history(input);

// Do stuff...

// Free buffer that was allocated by readline
free(input);
}
return 0;
}
</syntaxhighlight>
