Adds a strict command to run whatever you like with stricter settings.

-Xfatal-warnings is a great flag. Love it.

Also, I hate it so much. When I'm debugging, sometimes I just want to Do Things like comment out a bit of code for a minute, without fixing up my imports or getting rid of unused arguments. Just quit whining for a minute would you? I promise I'll fix it all up before I commit. I just need a moment alone with the compiler.

This plugin is simple. It adds a strict command which runs a subcommand with strictSettings applied. By default, those are scalacOptions += "-Xfatal-warnings" but you change that to whatever you like, I'm not your boss.

// plugins.sbt:
addSbtPlugin("net.gfxmonk" % "sbt-strict-scope" % "LATEST_VERSION")

(see releases for available versions)

The idea is that you can leave off -Xfatal-warnings in your main build, and in CI (or before you commit) you run sbt 'strict test' (note the quotes: you're passing the "test" argument into the strict command, you're not running strict followed by test). That'll run the test command, but with your strict settings enabled.

There are two settings to control what happens in strict scope:

• strictSettings: taskKey[Seq[Setting[_]]] - SBT settings to apply for the strict command
• strictScalacOptions: taskKey[Seq[String]] - Scalac options to apply for the strict command, removed outside the strict scope

By default strictSettings is empty, and strictScalacOptions contains only -Xfatal-warnings.

Note: As of version 2.0.0, this plugin removes strictScalacOptions from scalacOptions outside of strict mode. This is convenient when using e.g. sbt-tpolecat, which enables -Xfatal-warnings. You'll still get all of its other flags, but -Xfatal-warnings will only apply in strict mode.
