vim - 这个 : # vim:sw=4:ts=4:et: 的 Vim 功能名称是什么

Question

即使在使用 Vim 20 年后，我仍然忘记了 Vim 功能的名称，其中编辑器从文件开头(或我认为结尾)的注释中选取配置语句:

# vim:sw=4:ts=4:et:

谢谢提醒!

Answer 1

它被称为模式线

:he modeline

If you start editing a new file, and the 'modeline' option is on, a number of lines at the beginning and end of the file are checked for modelines. There are two forms of modelines.

  The first form:   [text]{white}{vi:|vim:|ex:}[white]{options}

 [text]         any text or empty
 {white}        at least one blank character (<Space> or <Tab>)
 {vi:|vim:|ex:} the string "vi:", "vim:" or "ex:"
 [white]        optional white space
 {options}      a list of option settings, separated with white space or ':',
                where each part between ':' is the argument for a ":set"
                command (can be empty)

将此添加到 $MYVIMRC:

setglobal modeline
