scala3 (3.9.0+ds2-1) experimental; urgency=medium
 .
   * Initial release. (Closes: #1125161)
   * Packages: scala3 (compiler, REPL, sbt bridge), scala3-library and
     scala3-scaladoc (scaladoc, command scaladoc-3).
   * scaladoc's Scala.js front end (search, contributors) is built from
     source with Debian's scala-js; the scala-js-dom facades are a
     component without their CC-BY-SA documentation comments.
   * Left out of scaladoc for now: Inkuire type-signature search, the
     Scastie run button and the dotty-icons font; generated pages load
     nothing from other sites.
   * The scaladoc command and its manual page are in scala3, so every
     slave of the scala alternative always has its target (no update-
     alternatives warnings, no file trigger); without scala3-scaladoc,
     which scala3 suggests, the command names that package.
   * scaladoc's type hierarchy graph: its scripts (d3, graphlib-dot,
     dagre-d3) come from node-d3, node-graphlib-dot and node-dagre-d3-
     renderer, copied into the generated site instead of loaded from
     CDNs; ux.js reads the zoom event the d3 5 way too.
   * Repack (+ds2): without the spec's binary fonts and MDN's deprecated
     banner.
   * sbt bridge built against sbt compiler-interface 2.x (patch 0007).

Format: https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/
Upstream-Name: scala3
Upstream-Contact: https://github.com/scala/scala3/issues
Source: https://github.com/scala/scala3
 The three components come from https://github.com/scala-js/scala-js (tag
 v1.22.0, ir/), https://github.com/scala/scala (tag v2.13.18,
 src/library) and https://github.com/scala-js/scala-js-dom (tag v2.8.1,
 dom/); see debian/README.source.
Comment:
 The upstream tarball is repacked (+ds) to remove files that are not in the
 preferred form for modification or are not DFSG free; see Files-Excluded.
 .
 Of the Files-Excluded entries, the test jars, class and TASTy files have
 no preferred-form source in the tree (canon/lib/a.jar is a symbolic link
 to the excluded canon/actual/a.jar); highlight.pack.js and
 bootstrap.min.css are minified copies with no source; dotty-icons.* is a
 generated icon font whose sources are not in the tree; the PDF files are
 rendered copies of figures and a paper whose sources are not in the tree;
 the Luxi fonts (Bigelow & Holmes) are under a licence that is not DFSG
 free; the Heuristica and octicons .woff, .eot and .ttf fonts are binary
 fonts without source (octicons.svg, the SVG font, stays); repl/src/sourcecode/LICENSE is a saved GitHub web page (HTML,
 scripts and GitHub's own notices) rather than a licence file, the
 licence of those sources is stated below. None of them is used by the
 build: the language specification and the documentation site are not
 built, the REPL is built from its sources only, and scaladoc is built
 with highlight.js from libjs-highlight.js in place of highlight.pack.js
 and without the icon font (debian/patches/0005).
 .
 The components scalajs-ir, scala213-library and scalajs-dom are cut
 from their upstream git tags by uscan with Files-Excluded-<component> and
 Files-Included-<component>. The scalajs-dom tarball is then rewritten by
 debian/repack-scalajs-dom without the Scaladoc comments of its sources
 (MDN documentation under CC-BY-SA 2.5 or later; see below).
 .
 The scaladoc jar in scala3-scaladoc also carries, as
 dotty_res/scripts/d3.min.js, graphlib-dot.min.js and dagre-d3.min.js,
 copies made at build time of the browser bundles of node-d3
 (BSD-3-clause, Mike Bostock), node-graphlib-dot (Expat, Chris Pettitt;
 with graphlib and lodash, Expat) and node-dagre-d3-renderer (Expat; with
 dagre, graphlib, lodash and parts of d3), recorded in the package's
 Static-Built-Using. They are not in this source package; their
 copyright files are in those packages.

Comment:
 The holder spellings above are the ones used in the source headers; most
 files carry no header and fall under the project licence (LICENSE,
 NOTICE.md). A few files say "Copyright (c) 2014 Contributor." with no
 licence of their own; they were contributed to Scala under its
 Apache-2.0 licence and contributor agreement. The same holds for the
 social icons in scaladoc/resources/dotty_res/images (GitHub, Discord,
 Twitter, Gitter), contributed in
 https://github.com/scala/scala3/pull/11273 and
 https://github.com/scala/scala3/pull/15697 under the CLA
 (https://cla.scala-lang.org/scala/scala3), which states each
 contribution is the contributor's original creation. The brands are
 trademarks of their owners.
 .
 NOTICE.md lists the parts derived from other projects under Apache-2.0:
 the Scala 2 compiler (scala/scala, same holders), the sbt compiler phases
 (see sbt-bridge/* below), the coverage instrumentation (scoverage), the
 presentation compiler (presentation-compiler/, adapted from the mtags
 module of scalameta/metals) and the SemanticDB serialisation (ScalaPB,
 see below). scoverage and Metals state no holder of their own; their
 authors contributed the adapted code to Scala 3.

Comment:
 Code from sbt's compiler interface. The headers that say only "sbt --
 Simple Build Tool, Copyright 2008, 2009 Mark Harrah" (or 2010) come from
 sbt 0.13, then under a BSD licence; that code was relicensed to
 Apache-2.0 with sbt 1.0 and zinc, whose copies carry "Copyright
 Lightbend, Inc. and Mark Harrah, Licensed under Apache License 2.0".
 ShowAPI.scala and the sbt-bridge sources are built into this package
 (scala3-compiler and scala3-sbt-bridge).

 Scala 2.13 standard library sources (component scala213-library). The
 CompletionLatch class in src/library/scala/concurrent/impl/Promise.scala
 says it is inspired by Doug Lea's public domain AbstractQueuedSynchronizer;
 the file itself is under the Scala header.

License: Expat
Comment:
 scala-js-dom 2.8.1 (component scalajs-dom), the DOM facades the scaladoc
 front end is compiled against. Its LICENSE states that the code is under
 the MIT License and that the documentation of the facades, taken from
 the Mozilla Developer Network, is under the Creative Commons
 Attribution-ShareAlike licence, version 2.5 or later. That documentation
 is the Scaladoc comments of the sources, and they are not in this
 component: debian/repack-scalajs-dom removes every /** ... */ comment
 when the component tarball is made (see debian/README.source), and the
 MDN "deprecated" banner sentence quoted in two @deprecated messages, so
 only the MIT-licensed code remains. The LICENSE file is kept unchanged as
 upstream's licence statement. The WebGL facades say "Copyright (C) 2014
 Matt Seddon. This source is donated in full to the scala-js-dom
 project."
 .
 The two JavaScript files of scaladoc's front end in the scaladoc jar
 (dotty_res/scripts/scaladoc-scalajs.js and contributors.js) are generated
 at build time by the Scala.js linker from scaladoc-js, the standard
 library, this component and the Scala.js libraries of the scala-js-library
 package (Apache-2.0, EPFL).
