Emacs shell模式下的Bash自动完成
在GNOME终端中,Bash执行智能自动完成。比如说Emacs shell模式下的Bash自动完成,bash,shell,emacs,autocomplete,Bash,Shell,Emacs,Autocomplete,在GNOME终端中,Bash执行智能自动完成。比如说 apt-get in<TAB> 在Emacs shell模式下,即使在我显式地使用source/etc/bash\u completion之后,这种自动完成也不起作用。上述示例在中保持为,或在当前目录中使用文件名自动完成,而不是有效的apt get命令选项。这大概是因为Emacs正在拦截Tab键的按下。如何在shell模式下启用智能自动完成功能?我不知道这个问题的答案。但它不能像您期望的那样工作的原因可能是因为emacs she
apt-get in<TAB>
在Emacs shell模式下,即使在我显式地使用source
/etc/bash\u completion
之后,这种自动完成也不起作用。上述示例在中保持为,或在当前目录中使用文件名自动完成,而不是有效的apt get
命令选项。这大概是因为Emacs正在拦截Tab键的按下。如何在shell模式下启用智能自动完成功能?我不知道这个问题的答案。但它不能像您期望的那样工作的原因可能是因为emacs shell中的完成操作是由emacs内部处理的(通过comint dynamic complete函数),并且没有内置这些智能完成函数
恐怕这不是一件容易解决的事情
编辑:njsf关于使用术语模式的建议可能是最好的。从M-x项开始
M-x term
它包含在标准的emacs发行版中(至少在Ubuntu和Debian上包含在emacs21 common或emacs22 common中)。我并不声称自己是emacs专家,但这应该可以解决您的问题:
创建:~/.emacs
加上:
(需要“shell”命令)
(shell命令完成模式)
Emacs接管了shell,因此BASH设置无法执行。这将为EMACS本身设置自动完成。正如Matli所说,这不是一项容易的任务,因为bash是从--noediting开始的,TAB绑定到comint dynamic complete
可以将TAB重新绑定到shell中的self-insert命令,并使用本地set键钩住
并使shell模式不以--noediting开始,由M-x定制变量RET explicit bash args执行,但我怀疑它不会适合所有其他编辑
您可能想尝试术语模式,但它有另一组问题,因为术语模式取代了其他一些常规键绑定
编辑:术语模式取代了其他常规按键,我指的是除了C-C之外的所有键,C-C成为能够切换缓冲区的转义。因此,您必须使用C-C-x k而不是C-x k来终止缓冲区。或者切换到emacs shell中的另一个缓冲区“C-C-x o”或“C-C-x 2”,实际上是emacs在自动完成,而不是bash。如果shell和emacs不同步(例如,通过使用pushd、popd或某些bash用户函数更改shell的当前目录),则自动完成停止工作
要解决这个问题,只需在shell中键入'dirs',事情就会恢复同步
我的.emacs中还包含以下内容:
(global-set-key "\M-\r" 'shell-resync-dirs)
然后点击Esc返回重新同步自动完成。我知道这个问题已经三年了,但我也一直对解决这个问题感兴趣。一次Web搜索让我找到了一段elisp,它让Emacs在shell模式下使用bash来完成。不管怎么说,这对我来说很有效
查看。我使用Prelude,当我点击Meta+选项卡时,它为我完成
同样,CTRL+I似乎也做同样的事情。请考虑另一个模式<代码> M X项< /C>,就像我在2011中的HIT问题那样做的那样。当时,我试图通过Inet收集所有的努力,使shell能够使用Bash完成,包括这个问题。但是自从在
术语模式
面前发现替代方案以来,我甚至不想尝试eshell
它是完整的终端模拟器,所以你们可以在里面运行交互式程序,比如午夜指挥官。或者切换到zsh
completion,这样您就不会在Emacs配置上浪费时间
您可以在bash中免费完成制表符。但更重要的是,您可以获得完整的读线功能,如增量或带前缀的命令搜索。要使此设置更方便,请检查我的

鼠标选择和Shift Insert的工作方式与我使用helm模式时的工作方式相同。它具有以下功能(按“TAB”键后):
我知道这篇文章已经有11年的历史了。但是我已经创建了一个函数来在Emacs中完成本机shell。它只向底层进程发送一个tab键并截取输出,因此它与shell本身中的输出完全相同
不,这并不能解决问题。它只在shell命令下工作,不在shell模式下工作。此外,它不会启用问题中请求的智能完成(它只会完成命令和文件名)。shell命令完成模式执行文件名完成,默认情况下启用。我想要Bash的完成功能(可以扩展,包括apt get和svn的子命令)。self insert命令不是它:它插入制表符,而不是将制表键传递给Bash。我没有术语模式命令,也不知道从哪里获取它。这是对不同问题的一个很好的回答!谢谢我使用自动跳转,这就是为什么DIR不同步的问题。Chris Conway,是的,对这一个::-)+1,因为有勇气回答一个三岁但仍然完全相关的问题。谢谢这已经在melpa中,使用M-x软件包列表软件包安装很简单,但最终它对我不起作用,我不知道为什么
