Vincent Ambo df4a09864a feat(tazjin/emacs): implement reliably-switch-buffer 
Adds a completing-read function (defaulting to ivy for me, but it
doesn't matter) that offers a reliable alternative to standard
buffer-switching implementations.

In particular, this implementation retains a mapping of
buffer names to their buffer *objects*, so that the correct buffer is
selected even if some renaming took place during the selection.

I tried to account for a bunch of the common behaviours I could think
of:

* invisible buffers are ... invisible
* entering a buffer name manually creates that buffer, if there is no
  match
* ... unless that buffer is an invisible buffer, in which case it is
  selected and switched to
* the first element is always `(other-buffer (current-buffer))`,
  because of the ordering of #'buffer-list

Yet, the entire code of my implementation is less than the *setup*
code of ivy-switch-buffers, so it's possible I missed something. Well,
I'll find out ...

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

  • //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
