Hi, Whilst working on the Reproducible Builds effort [0], we noticed that dub could not be built reproducibly. This is because the build system embeds timestamps in its man pages: ├── ./usr/share/man/man1/dub-add-local.1.gz │ ├── dub-add-local.1 │ │ @@ -1,8 +1,8 @@ │ │ -.TH DUB-ADD-LOCAL 1 "2025-05-24" "The D Language Foundation" "The D Language Foundation" │ │ +.TH DUB-ADD-LOCAL 1 "2024-04-21" "The D Language Foundation" "The D Language Foundation" (etc.) A patch is attached that simply exports dub's custom DIFFABLE environment variable. This was seemingly introduced to make these manpages, well, 'diffable' — that is to say, so that they generated in a deterministic manner.
