This relates to the (abandoned) cl/7256. Introduces a Cargo workspace at //tvix that is primarily intended to be used as a workaround for the annoying Nix+Rust tooling while having a consistent set of dependencies. This is driven in part by a desire to adopt crate2nix and get more granular Nix builds for Tvix's Rust projects, and in part by a need to split //tvix/eval into something providing the CLI (REPL etc.), and a library providing eval, without significantly altering the structure of build targets. To accomplish this the workspace has been designed to allow projects to remain independent build targets. I want to avoid lumping all the projects together - something like //tvix/eval should always be independent of other parts of tvix. A helper function in //tvix/default.nix lets downstream naersk projects construct a sparse root for the project which combines the workspace's `Cargo.lock` with the project's own `Cargo.toml`. Note that cargo commands in the workspace itself require the build dependencies of _all_ projects to be present, which is currently a bit annoying to accomplish. This introduces some breakage: 1. It breaks usage of rust-analyser without being in a shell with the dependencies of *all* Tvix projects, as it is not capable of respecting only the subset of dependencies for a part of the workspace. 2. It is no longer possible to run tests using `cargo test`, as the test generation crate we use does not work with workspaces: https://github.com/frehberg/test-generator/issues/6 This still works in the Nix build as we construct a Cargo project that looks like it's not in a workspace there. Until somebody fixes that crate / writes a new macro / does something else with the test suite, the way to run the tests is through the Nix build. Long-term we'll probably want to get rid of cargo completely, it's just a big wart and most tooling works without it if correctly configured, but we don't have time for that now.

depot
This repository is the monorepo for the community around The Virus Lounge, containing our personal tools and infrastructure. Everything in here is built using Nix.
A large portion of the software here is very self-referential, meaning that it exists to sustain the operation of the repository. This is the case because we partially see this as an experiment in tooling for monorepos.
Highlights
Services
-
Source code is available primarily through Sourcegraph on cs.tvl.fyi, where it is searchable and even semantically indexed. A lower-tech view of the repository is also available via cgit-pink on code.tvl.fyi.
The repository can be cloned using
gitfromhttps://cl.tvl.fyi/depot. -
All code in the depot, with the exception of code that is checked in to individual
//usersfolders, needs to be reviewed. We use Gerrit on cl.tvl.fyi for this. -
Issues are tracked via our own issue tracker on b.tvl.fyi. Its source code lives at
//web/panettone/. -
Smaller todo-list entries which do not warrant a separate issue are listed at todo.tvl.fyi.
-
We use Buildkite for CI. Recent builds are listed on tvl.fyi/builds and pipelines are configured dynamically via
//ops/pipelines. -
A search service that makes TVL services available via textual shortcuts is available: atward
All services that we host are deployed on NixOS machines that we manage. Their
configuration is tracked in //ops/{modules,machines}.
