vim 语法文件中的匹配制表符

Question

我正在使用 Vim 为我的待办事项编写语法文件 实际上，我会突出显示以 w:、h: 或 p: 开头的行，如下所示：

syn match todoHome  "^h: "
syn match todoWork  "^w: "
syn match todoPersonal  "^p: "
syn region todoHome start=/^h: / end=/\n/
syn region todoWork start=/^w: / end=/\n/
syn region todoPersonal start=/^p: / end=/\n/
syn region todoDone start=/^x: / end=/\n/

我想创建一些带有选项卡的子任务并以相同的方式突出显示它... 我知道正则表达式可以做到这一点，我尝试过：

syn region todoWork start=/^|[\t ]+w: / end=/\n/

但它不起作用......有任何线索吗？

Answer 1

<代码>| => \|

:help pattern

1. A pattern is one or more branches, separated by "\|".  It matches anything
   that matches one of the branches.  Example: "foo\|beep" matches "foo" and
   matches "beep".  If more than one branch matches, the first one is used.

   pattern ::=      branch
        or  branch \| branch
        or  branch \| branch \| branch
        etc.

+ => \+

\+  1 or more   as many as possible (*)

或者在模式的开头添加 \v！

Use of "\v" means that in the pattern after it all ASCII characters except
'0'-'9', 'a'-'z', 'A'-'Z' and '_' have a special meaning.  "very magic"
