Çreadline的功能 [英] C readline function

问题描述

在上大学的转让有人建议使用C 的readline 功能锻炼。我已经寻找它的参考，但仍然还没有找到它。它是否真的存在吗？在这头？你能请张贴链接引用？

In an assignment for college it was suggested to use the C readline function in an exercise. I have searched for its reference but still haven't found it. Does it really exist? In which header? Can you please post the link to the reference?

推荐答案

的Readline存在于两个地方， libreadline 和 libedit （又称 libeditline ）。两者具有相同的接口。所不同的是libreadline是在GPL下，libedit是3条款BSD。授权是真的不用于分配一个问题，至少我不认为它是。要么许可，您可以自由使用code。如果您对readline的链接，务必使整个程序 GPL 2或更高版本将满足任何的GPL版本支配系统的readline 。它可以是GPL2 +或GPL3 +，这取决于系统的年龄。我不主张任何许可证，这是给你的。

Readline exists in two places, libreadline and libedit (also called libeditline). Both have an identical interface. The difference is libreadline is licensed under the GPL, libedit is 3 clause BSD. Licensing is really not a concern for an assignment, at least I don't think it is. Either license allows you to use the code freely. If you link against readline, be sure to make the whole program GPL 2 or later which will satisfy whatever version of the GPL governs the system readline. It may be GPL2+ or GPL3+, depending on the age of the system. I'm not advocating either license, that's up to you.

请注意，要小心安装任一/或并根据需要调整连接（ -lreadline 的或的 -ledit 的或的 -leditline ）。两者都是图书馆，而不是标准C库的一部分。

Note, take care to install either / or and adjust linking as needed (-lreadline or -ledit or -leditline). Both are libraries and not a part of the standard C library.

修改（事后）：

如果释放程序到野外，它是一个很好的姿态，以允许用户使用他们的的readline 选择的配置。例如： - 与-的readline 或 - 与-libedit 等。这允许二进制包符合他们选择的许可，至少就的readline 而言。

If releasing a program to the wild, its a nice gesture to allow the user to configure it with their readline of choice. For instance: --with-readline or --with-libedit, etc. This allows a binary package that conforms to their choice of license, at least as far as readline is concerned.
