If [Goldmark](/getting-started/configuration-markup#goldmark) is set as `defaultMarkdownHandler`, the sanitizing logic adheres to the setting [`markup.goldmark.parser.autoHeadingIDType`](/getting-started/configuration-markup#goldmark).
|
|
|
|
Since the `defaultMarkdownHandler` and this template function use the same sanitizing logic, you can use the latter to determine the ID of a header for linking with anchor tags.
|
|
|
|
```go-html-template
|
|
{{ anchorize "This is a header" }} → "this-is-a-header"
|
|
{{ anchorize "This is also a header" }} → "this-is-also----a-header"
|
|
{{ anchorize "main.go" }} → "maingo"
|
|
{{ anchorize "Article 123" }} → "article-123"
|
|
{{ anchorize "<- Let's try this, shall we?" }} → "--lets-try-this-shall-we"
|
|
{{ anchorize "Hello, 世界" }} → "hello-世界"
|
|
```
