Dolmen Build Status

A library providing flexible parsers for input languages.


BSD2, see file LICENSE.


The Dolmen project aims at providing an assortiment of tools to help handle languages that are used in automated deduction and formal logic.

More precisely, the Dolmen project provides:

  • A few OCaml libraries for:
  • A binary (which is using the above libraries), to parse and typecheck input files. This could be used to check a file against its language specification, and/or obtain detailed errors. See the bin doc
  • A LSP server so that the feature sof the above binary can also be used inside your favorite editor. See the dolmen lsp doc


Online documentation for the libraries can be found at There is also a tutorial.

Supported languages

Currently the following parsers are working:

  • dimacs
  • iCNF
  • smtlib
  • tptp
  • zf (zipperposition format)

The following parsers are either work in progress, or soon to be work in progress:

  • coq
  • dedukti
