Fast edit/run feedback loop for Scala using Nailgun
# Step 1: install coursier and nailgun
brew install nailgun coursier/formulas/coursier
# Step 2: start nailgun server with the Scala compiler on the classpath
cs launch com.martiansoftware:nailgun-server:0.9.1 org.scala-lang:scala-compiler:2.13.1 --main com.martiansoftware.nailgun.NGServer -- 2113 &
# Step 3: create basic Scala hello world
echo 'println("Hello world!")' > Main.scala
# Step 4: assemble the classpath.
