Florian Klink c641fce62a feat(users/flokli/ipu6-softisp): expose qcam to $PATH 
This allows testing the camera connection without pipewire in between:

```

depot

Build status

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 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.

  • 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}.

Nix

  • //nix/readTree contains the Nix code which automatically registers projects in our Nix attribute hierarchy based on their in-tree location
  • //tools/nixery contains the source code of Nixery, a container registry that can build images ad-hoc from Nix packages
  • //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.
  • //web/blog and //web/atom-feed: A Nix-based static site generator which generates the web page and Atom feed for tazj.in (//users/tazjin/homepage) and tvl.fyi (//web/tvl)
  • //web/bubblegum contains a CGI-based web framework written in Nix.
  • //nix/nint: A shebang-compatible interpreter wrapper for Nix.
  • //tvix contains initial work towards a modular architecture for Nix.

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/aspen/xanthous: A (WIP) TUI RPG, written in Haskell.
  • //users/tazjin/emacs: tazjin's Emacs & EXWM configuration
  • //users/tazjin/finito: A persistent finite-state machine library for Rust.

Licensing

Unless otherwise stated in a subdirectory, all code is licensed under the MIT license. See LICENSE for details.
