Holide is an HOL to Dedukti translator. It accepts files in the OpenTheory article format version 6 (http://www.gilith.com/research/opentheory/article.html) and produces files for the Dedukti proof checker.

The source code is available online at: https://github.com/Deducteam/Holide

You need OCaml to compile it. To compile, simply run make in the main directory.

Usage: holide <options> <file>

  --just-check   Just check, do not translate
  -o <file>      Set output filename
  --quiet        Suppress all information
  --untyped-def  Use untyped declarations
  --version      Print version and exit
  -help          Display this list of options
  --help         Display this list of options

$HOLIDE_DIR/holide file.art

This produces a file named file.dk which is an encoding of the theory of the file file.art. All generated files depend on the main HOL logic, which is formalized in the file dedukti/hol.dk. To check it with Dedukti, do:

dkcheck -I $HOLIDE_DIR/dedukti file.dk

There are many ways to obtain proofs in the OpenTheory format. If you have the opentheory tool installed, you can automatically export and translate some theories of the OpenTheory standard library using:

make stdlib.
