From 7fe1331570918e9eae2a9868497afba7f61ad742 Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Tue, 4 Oct 2022 18:40:57 +0300 Subject: feat(tvix/eval): implement tvix's user-agent, err, nixVersion nixpkgs has hardcoded references to Nix versions, we need to provide it with something that looks like a Nix version while actually being a Tvix version. For now, we do this by stealing a trick out of the browser book and constructing a version that looks like a Nix version to Nix, but like a Tvix version to people who know what they are looking for. Nevermind that we don't actually have any kind of versioning for Tvix (yet?), other than depot revisions.
