Annotation
Description
Annotation is a special syntax in Markdown used to add extra information, explanations, or hints to a document.
Annotations are not directly displayed in the document; they require the user to manually click to be revealed.
Configuration
This feature is disabled by default. You need to enable it in the theme configuration.
export default defineUserConfig({
theme: plumeTheme({
markdown: {
annotation: true,
}
})
})Syntax
The Annotation syntax consists of two parts:
Inline Annotation
Insert an annotation marker inline using the [+label] syntax.
The annotation marker is composed of [+ + label + ]. To distinguish it clearly from the surrounding content, a space should be present at the left edge of [+label].
label is the tag for the annotation and can be any string.
The + symbol is required.
Defining Annotations
Define annotations in a separate area of the document using the [+label]: syntax.
The annotation definition area is composed of [+ + label + ]: + Content.
label should match the [+label] mentioned above and is used to identify the annotation tag.
Content can be written directly after the ::
[+label]: This is the content. **Markdown** syntax can be used here.Content can also start on the next line, but it must be indented. Consistent indentation should be maintained for multiple lines.
[+label]:
This is the content.
The indentation is consistent, so this line is also part of the content.
Even with a blank line above, this line is still consistently indented, so it is also content.
**Markdown** syntax can be used.
This line is no longer indented, so the annotation definition for this tag ended on the previous line.The content of the annotation definition is not rendered directly in the document. It is presented only when the inline [+label] marker is clicked.
