vim - 在命令行中指定 vim 文件类型

Question

我一直在处理很多没有扩展名的 C++ 文件，而且不得不输入 :set ft=cpp 太烦人了。每次我打开它们，所以我主要是在没有语法高亮的情况下工作。有没有办法在命令行中告诉 vim 文件类型？就像是:

$ vim --ft=cpp file_name

Answer 1

您可以使用 -c在读取第一个文件后启动 vim 以执行命令时的选项。

对于您的情况，您可以简单地使用标准 set filetype命令 -

vim -c 'set filetype=javascript'

您也可以使用 --cmd在加载第一个文件后执行命令。

从 vim 手册页中提取:

   -c {command}
               {command} will be executed after the first file has been read.  {command} is interpreted as an Ex command.  If the {command} contains spaces it must be enclosed in double quotes (this depends on  the  shell  that  is  used).
               Example: Vim "+set si" main.c
               Note: You can use up to 10 "+" or "-c" commands.

   --cmd {command}
               Like using "-c", but the command is executed just before processing any vimrc file.  You can use up to 10 of these commands, independently from "-c" commands.
