我可以清理repl吗？
我在 repl 控制台中使用了很多代码，如何清除它？我想要一个新的而不需要重新启动它。可以吗？
I have played with a lot of code in a repl console, how can I clear it? I would like a fresh one without restarting it. Can that be done?

如果您想清除您声明的所有临时变量和函数的当前命名空间，您可以使用这个衬里（或使其成为一个函数）：
或者
它并不声称为您提供一个非常干净的命名空间，只是一个具有较少通常在典型的 repl 会话中积累的垃圾。
小心使用：不要将地毯从脚下拉下来！
If you want to clear the current namespace of all temporary variables and functions you declared you can use this one liner (or make a function of it) :
or
It does not claim to give you a squeaky clean namespace, just one with less of the junk which usually accumulates in a typical repl session.
Use with caution : do not pull the rug from under your feet!
如果您通过终端窗口运行 repl（例如：MacOS 上的 Terminal.app 或 Linux 上的 xterm/aterm/urxvt 等），那么您可以输入 Control-L ，它应该会清除终端窗口并给你一个新的 repl 提示。然而，您之前定义的所有宏/原子仍然会在内存中，所以这只是一个“装饰”清除。
If you are running the repl through a terminal window (eg: Terminal.app on MacOS or xterm/aterm/urxvt etc on linux) then you can type Control-L and it should clear the terminal window and give you a new repl prompt. However all macros/atoms you previously defined are still going to be in memory, so this is just a "Cosmetic" clear.
在 EMACS/slime REPL 中
Cc Co 清除最后的输出（如果您输入的内容给出了很长的答案）
Cc Mo 清除所有内容
在 GNOME 终端中，您有一个菜单选项“终端/重置”和“清除”
In EMACS/slime REPLs
C-c C-o clears the last output (in case you've typed something that gave a very long answer)
C-c M-o clears the whole thing
In GNOME terminals, you've got a menu option Terminal/Reset and Clear
清理整个缓冲区的快捷方式： C-u C-c C -o
清理最后输出的快捷方式：C-c C-o
注意，旧的方法是： C-c M-o
另外，
cider-repl -clear-buffer（在我的机器上绑定到 C-ENTER s-c ）The shorcut to clean the whole buffer : C-u C-c C-o
The shortcut to clean the last output : C-c C-o
Note, the old way was : C-c M-o
Also,
cider-repl-clear-buffer(which is bound to C-ENTER s-c on my machine)如果您使用 Emacs +
nREPL，您可以：nrepl-clear-buffer或如果未启用按键绑定，请运行 Mx
nrepl-interaction-模式来启用它。您可以在 nrepl.el 和/或自定义按键绑定以满足您的需求。注意：您可以通过运行
Mx vnrepl-mode-map并按照以下命令找到系统中所有nREPL的按键绑定nrepl.el链接。If you are using Emacs +
nREPL, you can either:nrepl-clear-bufferorIf the key binding is not enabled, run Mx
nrepl-interaction-modeto enable it. You can find other useful shortcuts in nrepl.el and/or customize the key bindings to fit your needs.Note: you can find all
nREPL's key bindings in your system by runningM-x vnrepl-mode-mapand following thenrepl.ellink.我通过 Mx 使用 Emacs 命令
cider-repl-clear-buffer。还可以使用带有前缀参数的cider-repl-clear-output：Cu Cc Co。I use the Emacs command
cider-repl-clear-buffervia M-x. One might also usecider-repl-clear-outputwith a prefix argument: C-u C-c C-o.这取决于你所说的“干净”是什么意思。要删除“包”中的所有命名空间，您可以使用：
It depends what you mean by 'clean'. To remove all namespaces within a 'package' you can use:
对于像我一样使用 IntelliJ IDEA Cursive IDE 插件的用户：
您可以通过单击 REPL 框架顶部的此图标来“美观地”清除 REPL（保留您定义的符号等）：
< a href="https://i.sstatic.net/WyUK1.png" rel="nofollow noreferrer">
没有默认的按键绑定，但您可以通过打开您的首选项，导航到“键盘映射”>“轻松添加一个”。插件>草书，并添加“清除当前 REPL 的输出”的绑定。
或者，您可以右键单击编辑器并通过 REPL 命令访问“清除当前 REPL 的输出”。
For users of the Cursive IDE plugin for IntelliJ IDEA who end up here, like me:
You can "cosmetically" clear the REPL (keeping your def'd symbols etc.) by clicking on this icon at the top of the REPL frame:
There's no default key binding for this, but you can easily add one by opening your preferences, navigating to Keymap > Plugins > Cursive, and adding a binding for "Clear output for current REPL".
Alternatively, you can right-click in the editor and access "Clear output for current REPL" via the REPL commands.
