如何在HTML中嵌入Scala？

Coming from a background in PHP, I am used to the idea that I can simply embed server-side scripts into my HTML pages. Searching online, I haven't been able to find a simple echo <h1>Hello World</h1>; equivalent in Scala besides using a web framework like Lift. Can I do this with Scala?

PHP is an exception in being a language designed to be embedded in an HTML page. Apache has mod_php to do this for you. Scala, like many other languages, requires you to start up a web server to respond to requests and render HTML. You can use frameworks like Lift or Play, or you can make a Servlet-based app and deploy it into any Servlet container.

You could set up an Apache server to run CGI scripts and then insert a .scala file to be run by the scala command - but it would be incredibly slow as it would have to start up the Java VM every time. I wouldn't recommend that for anything other than scratching a mental itch.

See Scalate and PlayFramework

Scalate Scaml is very close to what you want

Scalate supports the following template formats

  • Mustache which is a Scala dialect of Mustache for logic-less templates which also work inside the browser using mustache.js
  • Scaml which is a Scala dialect of Haml and is very DRY for generating HTML / XHTML
  • Jade which is an even more DRY dialect of Scaml for HTML / XHTML markup generation
  • SSP which is like Velocity, JSP or Erb from Rails
