Calvin-L / calvins-nix-packages

Nix packages for me. I guess someone else might find them useful too.

Calvin's Nix Channel

This is a Nix "channel" with packages you can build.

To list available packages:

nix-env --description -qaPf . | sort

To build one, e.g. tlaps:

nix-build . -A tlaps -o result
./result/bin/tlapm --config

For a slightly more stable experience, replace . with ./stable.nix in the commands above. stable.nix pins exact upstream dependencies for a reproducible experience.

What's Here?

A few of my own projects:

• caltac, an opinionated set of Coq tactics.
• crash-safe-io, a simple and high-quality library implementing crash-safe file operations in Java.
• ezpsl, a language for modeling concurrent programs.
• many-smt, an SMT-LIB portfolio solver.
• retry-forever, for when failure isn't an option.

And a few open source things I use:

• tlaps, the TLA+ proof system. This is a newer and far more functional version than the one that ships with Nixpkgs. It includes:
  • isabelle_2011, which is the most recent version of Isabelle that works with tlaps. This package is heavily patched:
    • heaps are discovered using the $ISABELLE_PATH environment variable, so they can live somewhere outside $HOME
    • lots of functionality that tlaps does not need has been removed
    • fixes to compile with PolyML 5.9
  • ls4, which is used by tlaps.
  • ptl-to-trp-translator, which is used by tlaps. (TODO: compare with the one in the TLAPS source tree.)
  • zenon, a first-order logic solver.
  • zipperposition, a first-order logic solver.
• [tlatools-complete], a wrapper for the TLA+ tools that includes the community modules and TLAPS standard library.
• apalache, a symbolic TLA+ checker. (TODO: my version is very old. Can I use the Nix flake in the Apalache repo?)
• nbdkit, for userspace block devices on Linux.
• crosstool-ng, which I use for cross-compiling to Raspberry Pi.
