One thing I forgot to tell Efraim about is that I got around to looking at nar support in diffoscope. I know this isn't essential as you can just unpack the nars, then compare (as I think guix challenge does), but I've been thinking this could make it easier to compare nars. Anyway, as part of this I proposed adding lzip support, since nars can be lzipped, that turned out to be quite easy: https://salsa.debian.org/reproducible-builds/diffoscope/-/merge_requests/106 I'm finding nar support a bit harder though, I've raised a merge request anyway to see if I can get any feedback: https://salsa.debian.org/reproducible-builds/diffoscope/-/merge_requests/107 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKlBAEBCgCPFiEEPonu50WOcg2XVOCyXiijOwuE9XcFAmNmOY1fFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDNF ODlFRUU3NDU4RTcyMEQ5NzU0RTBCMjVFMjhBMzNCMEI4NEY1NzcRHG1haWxAY2Jh aW5lcy5uZXQACgkQXiijOwuE9Xe7EA//XKi8KTzWkbeDh9MTeoAPeUPodl8/hL3z GLUEXaLzHhlqRzLKDZvS9RxPzcr1DWoXZw58Xufia8ukbp6SQLJyxLU4q9Xw9cWO nOiYY32d9Ihv+HecK5O8Zxa0OE8Zd14LaBFG5J9fqvbiRoIY0oKQzr0MX2Hbm7gG vo+u6AfaSff/dDR5j8dKu/BswA9tilMzK+NRLAm1vh59j1pLf4DG0zEKtRwF27wv GjSvCT56cMmg7N1kEy66DxuVhMjQFCq44z/a36a6ehwz9wVCSweyTfemOKF7SRM1 IxNLqAgCoQbFpXfeGzimoVQ2xGmEtoieMysCNI1p9XgKF9NDKdauX6YkL2EtJQqM kuQjrZX/smXTTdAlqy6afO3o2yuduil43fg3a2nyqH/9lZTX3R5Engfu5LNCoHaf J4fO6NgSegKqprKEG6ypw8k0z45benzZuTj7d3rvtohdcybOtZLOewH1xmNmuLE4 80w0EhKpsGJmdZ+v6LCOP3CD9d27dU49BCTvxOvp1xmbnNxtr6UjRKU2bA7rVwcn Vy7H53iyy/mhYnGnET5Zn5sZFYJ5cJyASMaLGw7fblBQAFJGdi8aIpUWOrNyRBhq 4euaoKldvHZkjUDIhzVr+AMEJNW6aTldkmsmTnnV8qkSeWtSosaCkBe92wUOtfnE y8KpXbPj/eo= =6Gp9 -----END PGP SIGNATURE----- --=-=-=--
