How to load this code using Nix

nix-shell -p hol_light
rlwrap hol_light

loads "update_database.ml";;
load_path := "/Users/maggesi/Devel/HOL" :: !load_path;;
loadt "kanren-light/make.hl";;

How to build and the Docker image

Build the image:

docker build -t kanren-light Docker

or

docker build --pull --no-cache -t kanren-light Docker

then start the container:

docker run --rm -it -v "$PWD:/home/opam/work" kanren-light

ocaml is started automatically.

Then, load HOL Light:

#use "make.ml";;
load_path := "/home/opam/work" :: !load_path;;
loadt "kanren-light/make.hl";;

Build a docker container with the checkpointed HOL images

docker container rm kanren-light

docker run -it -h kanren-light --name kanren-light \
  -v "$PWD:/home/opam/work" \
  kanren-light screen

In one screen terminal

dmtcp_coordinator -q -p 7779
s

In another screen terminal (C-a c)

dmtcp_launch -q -j -p 7779 ocaml -I `camlp5 -where` -init make.ml

Once finished loading (before checkpoint)

load_path := "/home/opam/work" :: !load_path;;
loads "update_database.ml";;
Gc.compact();;

Back into the first terminal (C-a n to cycle between screen terminals)

c

Commit the docker container:

docker commit -m "With checkpointed HOL" kanren-light kanren-light-ckpt

docker container rm kanren-light-ckpt

docker create -it -h kanren-light --name kanren-light-ckpt \
  --entrypoint "/home/opam/hol-light/dmtcp_restart_script.sh" \
  -v "$PWD:/home/opam/work" \
  kanren-light-ckpt

docker start -i kanren-light-ckpt

Then load kanren light:

loadt "kanren-light/make.hl";;
