User documentation

Head over to the user docs for instructions on how to install scalafmt.

Quick help

• sbt compile or sbt core/compile (specific project).
• Run all unit tests: sbt test
• Run only formatting tests: tests/testOnly *FormatTests.
• Write new formatting test: read this doc.
• Build docs: See instructions on the site or locally at ./docs/contributing-website.md.
• Hack on sbt plugin: run sbt scripted.
• Run jmh benchmarks: ./bin/run-benchmarks.sh.
• Run formatter on millions of lines of code: tests/test:runMain org.scalafmt.ScalafmtProps (slow, and requires a lot of memory/cpu)
• Debug performance: after each test run in FormatTests, a flamegraph report like this one is generated in target/index.html. I usually keep a browser tab open at localhost:3000/target/index.html along with this background process: browser-sync start --server --files "target/*.html". See Browsersync.
