Welcome to The Incredible Proof Machine. The Incredible Proof Machine is a non-textual interactive theorem prover, or at least it will hopefully become one.
If you want to try it out, go to http://incredible.pm/.
The project consists of both Haskell and JavaScript code, so there are a few dependencies to install.
The Logic core is implemented in Haskell, and compiled to JavaScript using GHCJS. Installing GHCJS is not trivial, so we are using nix to obtain all build instructions. So to build the Haskell parts
-
Install
nixas described at https://nixos.org/download.html -
Add the Kaleidogen nix cache at https://kaleidogen.cachix.org/.
(This step is optional, but without it you will rebuild GHCJS which will take a long time.
-
Download or build all build dependencies:
nix-build --no-out-link shell.nix(Also optional, the next step will do it if you missed it.)
-
Enter a nix-shell:
nix-shellYou should now have
ghcjsin your path. -
Build everything
make(See
Makefilefor the individual steps) -
Open
./index.htmlin your browser and play! -
To run the testsuite, run
make test
If you only want to run this locally, or work on the UI (which is written in
plain JavaScript in folder webui/), you can also run
wget http://incredible.pm/logic.js -O logic.js
wget http://incredible.pm/sessions.js -O sessions.js
The JavaScript part of the project uses a few external libraries. To obtain
these, run ./install-jslib.sh.
Every push to the repository is tested on
GithubActions, and if the
tests succeed pushes to master are automatically pushed to
https://incredible.pm/.
This uses the script script ./deploy.sh dir/, which copies all files needed
to run the Incredible Proof Machien into the directory dir/, which should not
exist before.
