A bit more than one month after our last update, here are some highlights of the work of the Tweag Nix team:
Adam has been quite busy on the Trustix front:
Trustix now has its own webpage at https://build-transparency.org/. Also showing a demo of it in action:
A lot of work has been put on the frontend. There’s not much to show yet, but it’s progressing
The db format has been massaged to make it easier to consume in real-time and muuuuch faster
@edolstra has put a significant effort into the new-style commands, to
- significantly extend the
nix helpcommand, making it display the full man-page when relevant (#4336). Manpages are now in markdown to make the content easily resuable elsewhere.
- reorganize them to make their usage more consistent (d33eca, 29007f, …)
- Add several missing ones (#4429)
An experimental branch of hydra now supports building content-addressed derivations. While this probably won’t make it to hydra.nixos.org for some time, it will be tremendously useful to test things at scale.
The Nix implementation also keeps going with some ongoing work to handle signatures of content-addressed derivations.
@garbas is still doing an herculean work on the website, namely:
- The CSS styling of nixos.org has been extracted into its own repository so that it’s reusable by other sites,
- All the infra around status.nixos.org has now been moved to netlify,
search.nixos.org is being reworked to display more information and allow filtering the results (#261):
- @infinisil has been doing some internal refactorings on the Nix evaluator as a preparation for his work on lazy attribute names
- @infinisil opened and closed an RFC, leading to some discussions on the design and usage of fixed-output derivations
- Adam noticed some incorrect 301 redirects in channels.nixos.org leading to people seeing outdated results because of browsers caches
@edolstra removed the last bits preventing a statically-linked Nix to work, meaning that it’s now possible to fetch a statically-linked Nix and run
./nix --store ~/my-nixwithout having to install anything.
Although Nickel is technically not a Nix project, it is heavily Nix-inspired and might be of interest to some. So a few words on the awesome work that @yannham is doing on it:
- There’s a new query subcommand to retrieve the metadata associated to values from the command-line
- There’s ongoing work for adding a nice REPL (here, here, here and here). Most of this work should also be reusable as the backend for a coming LSP server
- The project is also getting a new CI setup (thanks to @garbas) to test it against several versions of the rust compiler and make IDE tooling usable in nix-shell or lorri.
