Profpatsch e4a7704583 feat(nix): add nix.tag, a way of discriminating via tagged unions 
Introduces the concept of a “tag”, a single-keyed attrset which
annotates a nix value with a name.
This can be used to implement tagged unions (by implying the list of
possible tags is well-known), which has some overlap with how
`nix.yants` does it.

However, the more fascinating use-case is in concert with a
so-called discriminator, `match` and hylomorphisms.

The discriminator can take a nix value, and add tags to it based on
some predicate.
With `match`, we can then use that information to convert the
discriminated values again.
With `hylo`, we can combine both the “constructive” discriminator step
with the “destructive” match step to recursively walk over a nix data
structure (based on a description of how to recurse, e.g. through attrset
values or list values), and then apply a transformation in one go.

depot

Build status

This repository is the monorepo for the community around tazjin's 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.

If you've ended up here and have no idea who I am, feel free to follow me on Twitter.

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 on code.tvl.fyi.

    The repository can be cloned using git from https://cl.tvl.fyi/depot.

  • All code in the depot, with the exception of code that is checked in to individual //users folders, 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.

All services that we host are deployed on NixOS machines that we manage. Their configuration is tracked in //ops/nixos.

Nix

  • //third_party/nix contains Tvix, our fork of the Nix package manager
  • //nix/readTree contains the Nix code which automatically registers projects in our Nix attribute hierarchy based on their in-tree location
  • //nix/yants contains Yet Another Nix Type System, which we use for a variety of things throughout the repository
  • //nix/buildGo implements a Nix library that can build Go software in the style of Bazel's rules_go. Go programs in this repository are built using this library.
  • //nix/buildLisp implements a Nix library that can build Common Lisp software. Currently only SBCL is supported. Lisp programs in this repository are built using this library.

We have a variety of other tools and libraries in the //nix folder which may be of interest.

Packages / Libraries

  • //net/alcoholic_jwt contains an easy-to-use JWT-validation library for Rust
  • //net/crimp contains a high-level HTTP client using cURL for Rust
  • //tools/emacs-pkgs contains various useful Emacs libraries, for example:
    • dottime.el provides dottime in the Emacs modeline
    • nix-util.el provides editing utilities for Nix files
    • term-switcher.el is an ivy-function for switching between vterm buffers
    • tvl.el provides helper functions for interacting with the TVL monorepo
  • //lisp/klatre provides a grab-bag utility library for Common Lisp

User packages

Contributors to the repository have user directories under //users, which can be used for personal or experimental code that does not require review.

Some examples:

  • //users/tazjin/homepage && //users/tazjin/blog: A Nix-based static site generator which generates the web page and Atom feed for tazj.in
  • //users/tazjin/finito: A persistent finite-state machine library for Rust.
  • //users/glittershark/xanthous: A (WIP) TUI RPG, written in Haskell.
  • //users/tazjin/emacs: tazjin's Emacs & EXWM configuration
