Description
When using code block options like :no-collapsed-lines or :collapsed-lines=N together with highlighted lines syntax (e.g., {1}), the highlighted lines feature stops working. The highlighted lines are not rendered, though other options (like collapsing behavior) still apply.
Steps to Reproduce
-
Install Shiki plugin.
pnpm i -D @vuepress/plugin-shiki@next
-
In
config.ts, enable Shiki plugin (either with or without extra configuration):import { shikiPlugin } from '@vuepress/plugin-shiki' export default defineUserConfig({ plugins: [shikiPlugin({})], });
We MUST enable Shiki plugin, otherwise everything works well.
-
Use a code block with both
:no-collapsed-lines(or similar) and highlighted lines syntax, for example:```java :no-collapsed-lines {1} 13213123 ```
-
Observe that line 1 is not highlighted, though the
:no-collapsed-linesoption is respected.If we don't add other syntax, for example:
```java {1} 13213123 ```
Then the highlighted lines work well.
Expected Behavior
Both the :no-collapsed-lines (or :collapsed-lines=N, title="...") option and line highlighting ({1}) should work simultaneously—lines specified in {...} should be visually highlighted, while other behaviors follow the given options.
Actual Behavior
Highlighted lines are ignored when any other option (e.g., :no-collapsed-lines, :collapsed-lines=5, title="...") is present in the same code fence.
I list a minimal reproduction below.
