Emmet

Enable abbreviation preview

Select this checkbox to have RubyMine show a popup with a preview of the entered abbreviation before actually expanding it.

Enable automatic URL recognition while wrapping text with <a> tag

• If this checkbox is cleared, and you wrap (Ctrl+Alt+J) a URL address with the <a> tag, RubyMine encloses the URL address in <a href=""></a> and places the caret inside the double quotes in the href attribute. For example, wrapping https://www.jetbrains.com will result in the following:

  <a href="|">https://www.jetbrains.com</a>

• If this checkbox is selected, and you wrap (Ctrl+Alt+J) a URL address with the <a> tag, RubyMine inserts the URL address inside the double quotes as the value of the href attribute and encloses the URL in <a href="<wrapped URL>"></a>. For example, wrapping https://www.jetbrains.com will result in the following:

  <a href="https://www.jetbrains.com">https://www.jetbrains.com</a>

• If this checkbox is selected, an editing position adds to the end of an HTML template ($END$).

• if this checkbox is not selected, then the new edit point is not added.
