Another month, another dev update from the Tweag Nix team:
Content-addressed Nix
We’re closer than ever to having this properly usable.
In particular, two big PRs by @thufschmitt got merged:
- #4592 brings a proper transparent substitution to content-addressed derivations,
- #4618 allows signing them like we can already do for input-addressed ones.
Another one (#4624) also temporarily introduces a new nix realisation
command to make it easier to work with these during the development phase.
Nix UX
-
@edolstra made the behavior of
--override-input
more intuitive by not writing the lockfile (77f5d1) -
@edolstra merged the very similar
nix flake inputs
andnix flake info
into a singlenix flake metadata
command (66fa1c)
Trustix
@adam is heavily working towards bringing Trustix to life for real with its first public deployment − in particular ensuring that it can be properly packaged and deployed with Nix.
In addition,
- The frontend saw a nice amount of work, getting cleaned and prettyfied in a lot of places;
- The development experience got a nice overhaul too, making it easier to contribute
Summer of Nix
Several of us had the chance of participating to the organisation of the summer of Nix, brainstorming with other community members before the official announcement, and now interviewing candidates.
In case you missed the announcement and are interested, go check it out at https://summer.nixos.org/
Nickel
In addition to numerous bugs fixes,
- Yann did a really huge amount of work on the Nickel stdlib (and it’s still improving), so that it comes with all the batteries you might need. This is tracked in #254.
- Some early internal testing also led to various syntactical and usability changes (#327, #317, #322)
- Parts of the typechecker got a nice clean-up fixing some midly annoying quirks (#315, #314)
- Yann opened an RFC issue on the design of record overriding, taking lessons from the various Nix extension mechanisms (NixOS modules, overlays, POP, etc…) and other similar systems in the wild (cue, jsonnet, etc…).
Misc
- @infinisil started prototyping an implementation of rfcs#81
- @thufschmitt rewrote an old Nix PR to add some compatibility tests against old Nix versions
-
@thufschmitt fixed
NIX_SHOW_STATS
with the newnix
command (#4615)
