Clefway — third-party software notices ============================================================================== Clefway's own code is not covered by this file. The website includes the following open-source software. Thank you to its authors. ============================================================================== Verovio 6.3.0 — LGPL-3.0-or-later https://www.verovio.org · source: https://github.com/rism-digital/verovio ============================================================================== Used by the Sheet Music Transposer (/transpose/) to engrave the preview and PDF. The file /vendor/verovio/verovio-toolkit-wasm.js is the unmodified build published by the Verovio project as the npm package "verovio@6.3.0" (dist/verovio-toolkit-wasm.js). It is loaded as a separate file and is not compiled into Clefway's own code, so you can replace it with your own (modified) build of Verovio at the same path. Verovio is free software: you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. It is distributed WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Full licence texts: /vendor/verovio/COPYING.LESSER (GNU LGPL v3) /vendor/verovio/COPYING (GNU GPL v3, which the LGPL refers to) Corresponding source code for this exact version (hosted directly on this site and upstream): /vendor/verovio/verovio-6.3.0-source.tar.gz (SHA-256: 095a561e9bd26c97787ad49e01009576d1ca234feae3995948c5aede97a40598) https://github.com/rism-digital/verovio/tree/version-6.3.0 How to substitute a modified compatible build of Verovio (LGPLv3 §4): 1. Set window.CLEFWAY_VEROVIO_WASM_URL = "" before opening a score, OR 2. Open /transpose/?verovioUrl=http://localhost:8080/verovio-toolkit-wasm.js (or a blob: / same-origin URL), OR 3. Use browser DevTools Local Overrides to replace /vendor/verovio/verovio-toolkit-wasm.js. See /credits/ for full instructions. Verovio itself contains third-party components under their own licences, including SMuFL music fonts (Leipzig, Bravura, Leland, Gootville, Petaluma — SIL Open Font License 1.1) and bundled libraries.
