VIM - 语法类和颜色方案 - 哪个类控制变量使用分隔符？

Question

这是由“darkbone.vim”配色方案提供的着色示例（更新）：

在“TMP=”行中，“${ }”分隔符与“TMP”变量名称不同。这是我想在另一个配色方案文件中复制的内容。

但是，我无法从变量本身（我已将其标识为“PreProc”）中识别出控制分隔符单独的类。

比较不同的文件，我发现darkbone.vim中没有包含“Delimiter”，所以我添加了，指定 guifg=#FF0000 ，但是没有对测试文件的全屏显示进行可识别的更改，其中分隔符和“调用”变量名称具有相同的颜色。

有人知道如何控制分隔符吗？

'scriptnames' 报告如下：

如果它能让事情变得更容易，这是我的草稿颜色方案文件：

Answer 1

语法高亮分两步完成：

1. 高亮组是使用“语法脚本”中的正则表达式定义的，并且通常链接到更通用的组，
2. 视觉属性分配给颜色方案中的突出显示组。

这样做的最直接后果是颜色方案无法突出显示不存在的突出显示组。

这导致了我们的下一个问题：根据sh 文件类型的默认语法脚本...

• ${ 属于 shDeref 和 PreProc 组，
• TMP 属于shDeref 和shDerefVar，
• } 属于PreProc，
• 它们都解析为PreProc 高亮组。

意味着your colorscheme in its current form 和sh 的默认语法脚本无法以不同方式突出显示${} 和TMP。

下面是您的脚本的前两行与darkbone.vim 和sh 的默认语法脚本的外观：

这是你的截图：

你会注意到有很多差异。

因此，如果您的颜色方案和默认语法脚本都将 ${TMP} 视为属于 PreProc 突出显示组的单个“块”，那么您可能正在使用不这样认为的第三方语法脚本。

此外，在您的配色方案中，唯一以橙色突出显示的突出显示组是 Function，因此在某处肯定有某种东西以某种方式覆盖了默认突出显示组。

FWIW，您可以使用以下命令来识别光标下项目的高亮组：

command! SynStack echo map(synstack(line('.'), col('.')), 'synIDattr(v:val, "name")')
