Source code

The app is free software under the GNU General Public License, version 3 or later. The engine, LOOM and this build of FFmpeg are under the GPL too, and the FFmpeg library inside Electron under the LGPL, at the versions in the table above, and their source is attached here:

• The app: the "Source code" archives GitHub attaches to this Release, the repository at v0.1.0-rc.3 (https://github.com/richc117/legible-cities-app/archive/refs/tags/v0.1.0-rc.3.tar.gz).
• ffmpeg-9.0.1-source.tar: FFmpeg 9.0.1's release tarball and its signature, x264 at its commit, zlib 1.3.2's release tarball and its signature, each as fetched and verified against the pins; the script that builds them, the pins and the vendor workflow; and BUILD.txt with every target's configure lines and the commit they came from.
• loom-1e4757838104-source.tar: LOOM at commit 1e4757838104d1e4d22186c9b77d5fc4b98681a0 with its submodules, the Windows port at commit 8c521a1815759a64b46a5f876dd84b1d8b0878d4, scripts/loom-windows-patch.py, which applies the port's changes to LOOM for the Windows build, the upstream release tarballs of zlib 1.3.2 and bzip2 1.0.8, verified by their publishers' signatures, and MSYS2's source packages (recipe and patches) for the exact zlib and bzip2 revisions the Windows tools link statically, the pins and the vendor workflow, BUILD.txt saying how each target is built, and TOOLCHAIN-win-x64.txt naming the MSYS2 packages the Windows tools were linked with.
• legible-cities-engine-0.8.3-source.tar: the engine at v0.8.3, as installed into the bundled Python, with the script that installs it and BUILD.txt naming the commit.
• electron-ffmpeg-44.2.0-source.tar.xz: the source of the FFmpeg library inside Electron 44.2.0: Chromium's FFmpeg at commit 2b68d2babae73714846961fb0ee47e3b3d2e39a9 with its build files and generated configuration, libopus, Chromium 152.0.7977.76's scripts, tools and GN configuration that build it, and Electron's patches and gn args, each verified by its git object id against the pins; and BUILD.txt saying what each part is and how the library is built.

Legible Cities 0.1.0-rc.2

A release candidate. This is rehearsal 2 of 0.1.0: the app inside reports version 0.1.0. Use it to test the release, not to keep.

Legible Cities turns a public transit timetable (a GTFS feed) into a schematic map and a timetable-driven animation, and exports stills, reels and GIFs. This is 0.1.0-rc.2, a pre-alpha.

These installers are not signed

The Mac app is not signed with an Apple Developer ID or notarised, and the Windows installer is not signed. macOS will say it cannot verify the app, and Windows SmartScreen will say it protected your PC. The install guide walks through opening the app anyway on each system, what the app writes and where, how to remove it completely, and how to report a problem.
