在vim中，如何突出显示TODO：和FIXME :？ [英] In vim, how do I highlight TODO: and FIXME:?
问题描述
在vim中，突出显示了FIXME和TODO，但是我无法使FIXME：和TODO：（请注意关键字后的冒号）突出显示？我应该在我的.vimrc文件中放些什么来实现此目的？
In vim, FIXME and TODO are highlighted, but I can't get FIXME: and TODO: (note the colon after the keyword) to highlight? What should I put in my .vimrc to make this happen?
推荐答案
嗯，您已经发现问题了，但是这里是
Well, you've already found the problem, but here's the why.
语法匹配有三种基本类型：关键字，匹配项和区域。关键字是固定的字符串，通常用于基本语言关键字（ int ， double 等）。您的情况，用于FIXME和TODO。我的意思确实是固定字符串。与匹配和区域（使用正则表达式）不同，它们必须是准确且完整的词。例如，从C语法开始：
There are three basic types of syntax matching: keywords, matches, and regions. Keywords are fixed strings, generally used for basic language keywords (int, double, ...) and also, in your case, for the FIXME and TODO. I really do mean fixed strings; they have to be exact and whole words, unlike matches and regions, which use regex. For example, from the C syntax:
syn keyword cTodo contained TODO FIXME XXX
在几乎所有内置语法定义中，都使用类似的组名（cTodo）。
It looks like that in pretty much all built-in syntax definitions, just with different group names (cTodo).
iskeyword 告诉vim给定字符是否可以作为关键字的一部分。默认情况下，它不包含冒号，因此在查找关键字时，vim会将 FIXME：视为 FIXME，并忽略冒号。如果您在冒号（ set iskeyword + =：）上加粗，现在可以定义额外的突出显示：
iskeyword tells vim whether a given character can be part of keyword. By default, it does not include colons, so when looking for keywords, vim sees "FIXME:" as "FIXME", and ignores the colon. If you tack on the colon (set iskeyword+=:), you can now define an extra bit of highlighting:
syn keyword myTodo contained TODO: FIXME:
您如何将其工作到现有语法/突出显示组中。如果仅用于一种文件类型，则可以将其添加到该语法的todo组中（例如cTodo）。如果到处都需要它，可以按照我的建议执行 myTodo，然后将其直接链接到Todo高亮显示组（
It's up to you how you want to work it into the existing syntax/highlight groups. If it's for just one filetype, you could add it to that syntax's todo group (e.g. cTodo). If you want it everywhere, you can do "myTodo" as I suggested, then link it straight to the Todo highlighting group (hi def link myTodo Todo).
或者，您可以单独保留 iskeyword （我可能会建议这样做），而只需使用匹配项：
Alternatively, you can leave iskeyword alone (I'd probably recommend this), and simply use a match:
syn match myTodo contained "\<\(TODO\|FIXME\):"
hi def link myTodo Todo
