How can I find a description of scala compiler flags/options?

Question

How can I find all of the flags for the latest scalac version? After googling for hours I have found only outdated docs. (for example, they don\'t even mention \"-feature\" flag

Answer 1

The closest I have been able to find is the relevant source files for the compiler. Unfortunately the options are spread among several files. As of this writing, it breaks down like so:

• StandardScalaSettings (for basic flags)
• ScalaSettings (for advanced flags)

These will of course be for the current development version of the compiler, so if you want options for a specific version of scalac, you'll need to use the "branch" drop-down menu to view the correct version tag.
