MacVim：通过使用`slias mvim ='open -a麦克维姆（MacVim）从命令行创建新文件。

Question

当我使用 vim newfilename 打开一个文件并且该文件没有退出时，vim 将创建一个名为 newfilename 的新文件。

然而，MacVim 不能以这种方式工作 --- 即 mvim newfilename (alias mvim="open -a macvim") 将导致错误： newfilename 不存在

有没有办法配置 MacVim 使得 mvim newfilename (alias mvim="open -a macvim") 将创建一个新文件并打开它？

Answer 1

我猜测错误消息来自 open，而不是来自 vim。您可以用函数替换别名；

mvim () {
    local f
    for f; do
        test -e "$f" || touch "$f"
    done
    open -a macvim "$@"
}

如有必要，这将在打开文件之前创建空文件。

您不需要打开命令的 mvim 别名，您可以使用 mvim 启动器脚本。将 mvim 添加到您的路径后，然后运行 ​​mvim newfile ，现在将在新的 MacVim 窗口中打开一个新文件缓冲区，就像 gvim 一样。

上面链接的 MacVim mvim 脚本：

#!/bin/sh
#
# This shell script passes all its arguments to the binary inside the
# MacVim.app application bundle.  If you make links to this script as view,
# gvim, etc., then it will peek at the name used to call it and set options
# appropriately.
#
# Based on a script by Wout Mertens and suggestions from Laurent Bihanic.  This
# version is the fault of Benji Fisher, 16 May 2005 (with modifications by Nico
# Weber and Bjorn Winckler, Aug 13 2007).
# First, check "All the Usual Suspects" for the location of the Vim.app bundle.
# You can short-circuit this by setting the VIM_APP_DIR environment variable
# or by un-commenting and editing the following line:
# VIM_APP_DIR=/Applications

if [ -z "$VIM_APP_DIR" ]
then
    myDir="`dirname "$0"`"
    myAppDir="$myDir/../Applications"
    for i in ~/Applications ~/Applications/vim $myDir $myDir/vim $myAppDir $myAppDir/vim /Applications /Applications/vim /Applications/Utilities /Applications/Utilities/vim; do
        if [ -x "$i/MacVim.app" ]; then
            VIM_APP_DIR="$i"
            break
        fi
    done
fi
if [ -z "$VIM_APP_DIR" ]
then
    echo "Sorry, cannot find MacVim.app.  Try setting the VIM_APP_DIR environment variable to the directory containing MacVim.app."
    exit 1
fi
binary="$VIM_APP_DIR/MacVim.app/Contents/MacOS/Vim"

# Next, peek at the name used to invoke this script, and set options
# accordingly.

name="`basename "$0"`"
gui=
opts=

# GUI mode, implies forking
case "$name" in m*|g*|rm*|rg*) gui=true ;; esac

# Restricted mode
case "$name" in r*) opts="$opts -Z";; esac

# vimdiff, view, and ex mode
case "$name" in
    *vimdiff)
        opts="$opts -dO"
        ;;
    *view)
        opts="$opts -R"
        ;;
    *ex)
        opts="$opts -e"
        ;;
esac

# Last step:  fire up vim.
# The program should fork by default when started in GUI mode, but it does
# not; we work around this when this script is invoked as "gvim" or "rgview"
# etc., but not when it is invoked as "vim -g".
if [ "$gui" ]; then
    # Note: this isn't perfect, because any error output goes to the
    # terminal instead of the console log.
    # But if you use open instead, you will need to fully qualify the
    # path names for any filenames you specify, which is hard.
    exec "$binary" -g $opts ${1:+"$@"}
else
    exec "$binary" $opts ${1:+"$@"}
