vim - 在交互模式下不识别别名？

Question

与从vim执行的命令相同的问题是没有识别bash命令别名,但是那里的解决方案不起作用.

我在〜/ .vimrc中设置了这些变量:

set shellcmdflag=-ic
set shell=/bin/bash\ -i

我的〜/ .bash_aliases中有别名:

rgr() { if [ ! -z "$2" ]; then grep -rI --exclude=\*.svn\* "$1" * --include=$2 ; else grep -rI --exclude=*svn* "$1" * ; fi ; }

从命令行执行时,它工作,但当我尝试从vim(:!rgr test)调用它时,我收到一条错误消息,vim退出:

bash: rgr: command not found

[4]+  Stopped                 vi ~/somefile

如果我禁用交互模式,我只是得到"命令未找到"消息,并且vim不会退出.

如何让vim识别我的别名？我在OS X和Ubuntu上都重现了这种行为.

如果您想要非交互式shell(默认)但扩展bash别名,请将别名定义放在文件中,例如.bash_aliases并在此文件中显式启用别名扩展:

shopt -s expand_aliases
alias la='ls -la'

然后将其添加到您的.vimrc所以每次从vim中运行shell命令时实际读取别名文件:

let $BASH_ENV = "~/.bash_aliases"

尝试将此行添加到您的~/.vimrc:

set shell=/bin/bash\ -i

然后vim将使用默认情况下-i从中读取的交互式shell()~/.bashrc.有关:h shell详细信息,请参阅shell.

我看到这与你说的不起作用的先前答案基本相同.请在您的机器上尝试下面的示例会话,看看您是否有类似的结果(并从您在示例中看到的输出中发布任何错误/偏差).

$ cat .bash_aliases 
alias test_alias="echo test alias"
test_func () {
        echo test func
}
$ vim 
[vim]:set shell=/bin/bash
[vim]:!type test_alias
/bin/bash: line 0: type: test_alias: not found

shell returned 1

Press ENTER or type command to continue
[vim]:!type test_func
/bin/bash: line 0: type: test_func: not found

shell returned 1

Press ENTER or type command to continue
[vim]:set shell=/bin/bash\ -i
[vim]:!type test_alias
test_alias is aliased to `echo test alias'

Press ENTER or type command to continue
[vim]:!type test_func
test_func is a function
test_func () 
{ 
    echo test func
}

Press ENTER or type command to continue

至于为什么它不能开始,bash只是简单地运行(即既不是交互式也不是登录;默认为vim和大多数其他目的),它会读取指定的任何文件$BASH_ENV:

   When bash is started non-interactively, to  run  a  shell  script,  for
   example, it looks for the variable BASH_ENV in the environment, expands
   its value if it appears there, and uses the expanded value as the  name
   of  a  file to read and execute.  Bash behaves as if the following com?
   mand were executed:
          if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
   but the value of the PATH variable is not used to search for  the  file
   name.

通过添加-i,我们使shell具有交互性,因此它读取~/.bashrc:

   When an interactive shell that is not a login shell  is  started,  bash
   reads  and  executes  commands  from /etc/bash.bashrc and ~/.bashrc, if
   these files exist.  This may be inhibited by using the  --norc  option.
   The  --rcfile  file option will force bash to read and execute commands
   from file instead of /etc/bash.bashrc and ~/.bashrc.

该*profile文件启动一个登录shell时读:

   When  bash is invoked as an interactive login shell, or as a non-inter?
   active shell with the --login option, it first reads and executes  com?
   mands  from  the file /etc/profile, if that file exists.  After reading
   that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile,
   in  that order, and reads and executes commands from the first one that
   exists and is readable.  The --noprofile option may be  used  when  the
   shell is started to inhibit this behavior.

我通过手册页得到了这个工作bash:

set shell=/bin/bash\ --rcfile\ ~/.bash_profile

同样,--init-file作品.

请注意,这\ -i 不是必需的,但可以添加到命令中:

set shell=/bin/bash\ --rcfile\ ~/.bash_profile\ -i

示例:

~/.bash_profile 包含

  source ~/.bash_aliases

~/.bash_aliases 包含

  alias rdc="open -a \"Remote Desktop Connection\""

~/.vimrc 包含

  set shell=/bin/bash\ --rcfile\ ~/.bash_profile
  map ,r :!rdc &<cr>
