Currently the following parsers are working:
zf (zipperposition format)
The following parsers are either work in progress, or soon to be
work in progress:
This library provides functors to create parsers from a given
representation of terms. This allows users to have a parser that
directly outputs temrs in the desired form, without needing to
translate the parser output into the specific AST used in a project.
Parsers (actually, the functors which generates parsers) typically takes
four module arguments:
A representation of locations in files. This is used for reporting
parsing and lexing errors, but also to attach to each expression parsed
A representation of identifiers. In some languages, there are syntactic
scopes, which are handled using namespaces for variable names. In order
to not pollute the Term module with it, the namespaces are dealt with
in this module separately.
A representation of terms. The functions in this module are used by the
parser to build the various types, terms and formulas corresponding
to the grammar of the input language. All functions of this module
typically takes as first (optional) argument a location (of the type
defined by the previous argument) so that is is possible to have
locations for expressions.
A representation of top-level directives. Languages usually defines
several top-level directives to more easily distinguish type definitions,
axioms, lemma, theorems to prove, new assertions, or even sometimes direct
commands for the solver (to set some options for instance). Again, the functions
in this module usually have a first optional argument to set the location
of the directives.
Some simple implementation of theses modules are provided in this library.
See the next section for more information.
Examples of how to use the parsers can be found in src/main.ml . As mentionned
in the previous section, default implementation for the required functor arguments
are provided, and can be used.
For instance, the following code instantiates a parser for the smtlib language
and try to parse a file named "example.smt2" in the home of the current user:
open Dolmen module P = Smtlib.Make(ParseLocation)(Id)(Term)(Statement) let _ = P.parse_file "~/example.smt2"
