Automatically link inline code

autolink(text)

autolink_url(text)

Arguments

text

String of code to highlight and link.

Value

If text is linkable, an HTML link for autolink(), and or just the URL for autolink_url(). Both return NA if the text is not linkable.

Options

downlit provides a number of options to control the details of the linking. They are particularly important if you want to generate "local" links.

  • downlit.package: name of the current package. Determines when topic_index and article_index

  • downlit.topic_index and downlit.article_index: named character vector that maps from topic/article name to path.

  • downlit.rdname: name of current Rd file being documented (if any); used to avoid self-links.

  • downlit.attached: character vector of currently attached R packages.

  • downlit.local_packages: named character vector providing relative paths (value) to packages (name) that can be reached with relative links from the target HTML document.

  • downlit.topic_path and downlit.article_path: paths to reference topics and articles/vignettes relative to the "current" file.
