我已经使用 vim 几个月了，我仍然在尝试改善我对这个伟大编辑器的体验。

我尝试做的是为香料网表（电子资料）创建一个语法高亮文件。

我试图强调以下模式：

.SUBCKT or_gate AB OUT

（*or_gate* 是该单元的单元
A、B和OUT bieng 引脚的名称）

我尝试做的是用 3 种不同的颜色突出显示它：

  • 一个用于 .SUBCKT
  • 一个用于 or_gate （单元格）
  • 一个用于 A、B 和 OUT（引脚）

所以我正在查看以 .SUBCKT 开头的行，并试图找到一种方法来匹配该行的不同单词。

我尝试了很多不同的syn match组合或嵌套syn region但我只是觉得我做错了。

这是我尝试之一的示例：

syn region spiceCKT start ="\.SUBCKT" end ="$"包含=spiceCell,spicePins

syn region spiceCell start ="\.SUBCKT"rs=e end ="$"包含

syn region spicePins start ="\.SUBCKT\s\S*"rs=e end ="$"包含

I tried to play with the pattern (\s\S*), to add/remove the rs=e parts, or even to define the start or end patterns adding \zs and \ze.

In the end I did not manage to make it work and I just feel like I'm making it way more complicated that it should be.

Anyone could help me figuring out what are my mistakes and how to handle such pattern highlighting?

You could try syn match with look-behind:

syn match spiceCKT /^\s*\.SUBCKT/
syn match spiceCell /\v(^\s*\.SUBCKT\s+)@<=or_gate/
syn match spicePins /\v(^\s*\.SUBCKT\s+or_gate\s+)@<=A B OUT/

I just did a small test. I don't have your syntax groups, I just tried with default groups, it looks like this:

Thank you for your answer! It does work. Thank you for the tip.

The only drawback is that it's a bit slow when the file has to load complete lines.

I complete your code to fit my needs:

syn match spiceCKT /^\s*.SUBCKT/

syn match spiceCell /\v(^\s*.SUBCKT\s+)@<=\S*\s+/

syn match spicePins /\v(^\s*.SUBCKT\s+or_gate\s+)@<=(\s*\S*)*/

The lines with @<= are making the screen a bit laggy when I scroll down. I'm still trying to work on it.
