Artifacts

Name	Description
lib_c	scala-library on the compilation classpath
lib_r	scala-library on the runtime classpath
c	scala compiler
js_c	Scala.js compiler
js_ld	Scala.js linker
js_jslib_c	Scala.js library on the compilation classpath
js_jslib_ld	Scala.js library on the linking classpath
js_lib_c	Scala.js scalalib on the compilation classpath
js_lib_ld	Scala.js scalalib on the linking classpath

Inputs

Name	Description
scalaV	build tool Scala version setting
scalaJSV	build tool Scala.js version setting
scalaDepV	newest Scala version from dependencies

Current Situation

Scala project

Artifact	Nominal	Scala Code
lib_c	scalaV	scalaV
lib_r	scalaV	scalaV
c	scalaV	scalaV

Notes: No js_* artifacts.

Scala.js project

Artifact	Nominal	Scala Code	Scala Dep	Scala.js Code	Scala.js IR
lib_c	scalaV	scalaV
c	scalaV	scalaV
js_c	(scalaV, scalaJSV)		scalaV	scalaJSV
js_ld	scalaJSV			scalaJSV
js_jslib_*	scalaJSV		f(scalaJSV)	scalaJSV	scalaJSV
js_lib_ld	scalaJSV	f(scalaJSV)		scalaJSV	scalaJSV

Notes:

• lib_r is not present (no JVM runtime)
• js_lib_c is not present (build tools force lib_c at compilation time).
• js_jslib_*, js_lib_ld are a single JAR.

This Proposal

js_jslib_*	scalaDepV		scalaDepV	f(scalaDepV)	f(scalaDepV)
js_lib_ld	scalaDepV	scalaDepV		f(scalaDepV)	f(scalaDepV)

Scala.js project (Option 1a)

Artifact	Nominal	Scala Code	Scala Dep	Scala.js Code	Scala.js IR
