Using `title` with ScalaTags

Question

The title tag is not working as expected with the ScalaTags library.

import scalatags.Text.all._

title("My Awesome Website")

How can I get this to work?

Help docs/tutorials are conveniently missing the ubiquitous title tag. I hope the dev fixes this..

Not Working as Expected:

If you look at how tags such as link, script, head, html are used the title tag should work the same.

For some reason the dev chose to make this tag ConcreteHtmlTag[Nothing] rather than the former tag's type ConcreteHtmlTag[String]. Its also strange that this tag is in the Tags2 package rather than Tags, it is a commonly used tag after all.

Answer 1

This one seems to work:

scala> scalatags.Text.tags2.title("test")
res7: scalatags.Text.TypedTag[Nothing] = <title>test</title>

It seems like the title in scalatags.Text.all is a tag attribute (scalatags.generic.Attr) and not a TypedTag. Whether or not this is misplaced or not (or should be TypedTag[String]), I don't know. Perhaps it's just a symbol collision in your code.

An explicit import scalatags.Text.tags2.title ought to help.

Answer 2

Instead of importing all, there are alternate imports you can use.

import scalatags.Text.short._
import scalatags.Text.tags2._

html(
  head(
    title("Your Title Here")
  ),
  body(

  )
)

More examples are in Managing Imports section in docs.
