sbt-jflex-scala

A plugin for sbt 0.13.x/1.0.x, generates Scala code based on a jflex specification.

This is inspired by sbt-jflex.

Setup

project/plugins.sbt:

• stable (recommended)

  addSbtPlugin("com.github.3tty0n" % "sbt-jflex-scala" % "0.4.0")

• development

  addSbtPlugin("com.github.3tty0n" % "sbt-jflex-scala" % "0.4.1-SNAPSHOT")

Usage

src/main/flex:

Put your *.flex file.

In your sbt shell:

Manual generation

> jflexGenerate

then Yylex.scala is generated in src/main/scala.

Auto generation

If you execute compile, Yylex.scala will be generated in src/main/scala automatically.
