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- and Files-Included-. 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.

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.

Files: scalajs-dom/* Copyright: 2013 Li Haoyi 2014 Matt Seddon 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).
