The first release of open-sourced Inform 7 that includes Linux binaries, and a Linux GUI, is now available, so I suppose this is now ripe for packaging in Debian, should anyone be up for it.
https://github.com/ganelson/inform/releases/tag/v10.1.2 is the first overall Inform 7 release that includes Linux binaries. (The first official release of the open-source version was on 21 August, but without finalised Linux integration.) This version number primarily denotes the toolchain, but also incorporates specific versions of the GUIs. I believe https://github.com/ptomato/inform7-ide/releases/tag/2.0.0 is the source code for the version of the Linux IDE that's included in that. The tag and binaries are only a few hours old at this point; I don't know if detailed Linux release notes are coming. INSTALL.md in the inform7-ide repository looks to have a few clues relevant to distro packagers. This forum thread where the IDE developer previously sought feedback on release candidates may also be useful: https://intfiction.org/t/release-candidate-of-inform-7-ide-for-gnome-testing-help-wanted/55045 One detail about the IDE that might be relevant for packaging is that, unlike previous versions, new IDE versions reportedly "feature the ability to select the version of Inform used, so that if v10.1.0 does not agree with your existing Inform project, you can easily revert that project to use 9.1, 9.2 or 9.3". <https://intfiction.org/t/inform-7-v10-1-0-is-now-open-source/55674> While Debian is unlikely to ever package those old closed-source 9.x versions of the toolchain, presumably the same will apply to new 10.x+ versions. This might inform the division into packages and their dependencies.
