transform.CanHighlight

Reports whether the given language is supported for syntax highlighting.

Syntax: transform.CanHighlight LANGUAGE
Returns: bool

Usage

The transform.CanHighlight function reports whether the given language is supported for syntax highlighting. The LANGUAGE argument is case-insensitive. See the list of supported languages.

If the syntax highlighter does not support a language, it renders the code without highlighting. Use this function before calling the transform.Highlight or transform.HighlightCodeBlock function to decide how to handle an unsupported language, such as by substituting a different language.

Examples

{{ transform.CanHighlight "go" }} → true
{{ transform.CanHighlight "klingon" }} → false
