- Replace the
Plain
statement with theOther
statement, which is a more general version (PR#190)
- Treat quoted symbols from the stdlib as symbols, regardless of
their contents. Previously a
|assert|
would be understood as the reserved workassert
, allowing e.g.(|assert| false)
. From now on these are understood as symbols, so one can(declare |assert| () Bool)
(PR#198) - Add parsing extensions for the smtlib2 language (PR#190, PR#194)
- Better split elements of clauses in
cnf
TPTP statements (PR#190) - Ensure illegal chars raise the correct error during lexing (Issue#191, PR#192)

- Enforce some missing constraints on bitvectors indexes and sizes for the smtlib2 BV theory (PR#172, PR#175)
- Slightly improve wording for errors and warnings concerning non linearity and other arithmetic restrictions (PR#184)
- More information for reserved Id, resulting in more precise errors when smt2 scripts use reserved ids (PR#193)
- Expose implicit declarations/definitions that happen during typechecking (PR#199)
- Treat smtlib
:named
annotations as implicit definitions as required by the spec (PR#199) - Add a warning for unknown attributes in smtlib2. This replaces
the
unbound id
error that some files could raise before when using non-standard attribtues (PR#207) - Only type annotations on quantified formulas and binders once. Previously, these were typed twice so that they can be attached to both the body of the bound formula and the quantified formula itself. (PR#207, PR#210)
- Add the String theory to the ALL logic of smtlib2 (PR#182)
- Add examples in the doc and tuto for type-checking (including a minimal working example in the tutorial).

Flow
module for flow checking (PR#135) - Add the
check
function intyper.ml
/typer_intf.ml
- Add
update
andupdate_opt
inState
(PR#156) - Print type definitions in the printer of typed statements (PR#157)
- Prelude statements have been removed and replaced with prelude files (PR#160)
Typer.additional_builtins
is now aState.key
and takes the current state and language as arguments (PR#160)
- Fix bug in bitvector implementation: negative inputs to
bvsmod
would raise an internal error (PR#138) - Remove the "error" keyword and statement from smtlib2 response (model) files (PR#139)

- Add
parse_raw_lazy
to parse a string into a lazy list of statements (PR#125) - Add support for mutually recursive functions and predicates in Alt-ergo's native language (PR#129)
- Properly add binding locations for implicit type variables (PR#123)
- Ensure that type of recursively defined symbols are freshened to avoid type variables sharing between declaration and definition (PR#123)
- Use
GC.finalise
instead ofGc.finalise_last
inloop/parser.ml
in order to avoid a bug in the ocaml 5.0 runtime, see ocaml/ocaml#12001 (PR#128) - New module to implement Alarms (size/time limits) (PR#117)
- Add optional argument to
Pipeline.run
to specify an alarm implementation (PR#117) - Add a

- Add a minimal reporting style accessible via the
--report-style
option. When used, thedolmen
binary will use at most one line to output the result of processing the input file - Add an option to the
dolmen
binary to force a specific smtlib2 logic, overriding the one given in the file. This is accessible via the--force-smtlib2-logic
option - Add some documentation for setting up the lsp with neovim (PR#114)
- Added model verification. This currently supports all builtins, except for String/Regular expressions.
- Fix long compilation time of tptp parser due to flambda (PR#111)
- Replace some
assert false
by proper error messages when there is not the same number of function signatures as function definitions in adefine-funs-rec
command in smtlib2 - Accept all reserved words in s-exprs in smtlib (mainly affects parsing of attributes)
- Added a parser for the smtlib model specification language
- Fix doc comments mentionning removed parameters (PR #107, issue #106)
- Add an option to print syntax error identifiers (mainly to be used for debug)
- Register a printer for the
Uncaught_exn
exception (mainly useful for library users) - Add a tag to differentiate predicates from functions in alt-ergo (PR#104)
- Properly typecheck s-expressions in attributes for smtlib2 (most notably in :patterns attributes for psmt2)
- Cleaned up handling of definitions: instead of using
the functors in
Def
, definitions are now simply declared using the functions exposed by the typechecker - Stop emitting unused warnings for type wildcards
- Expose term constants in the
Std.Expr
module (PR#112)
- Changed the state type from a record to an heterogeneous map. This simplifies interfaces for all Loop modules, and makes it much more extensible.
- Added initialization functions for each pipe in order to correctly init the expecteds keys in the state
- Allow users to better control the interactive prompt when parsing from stdin (PR#113)
- Added source input snippet printing for errors and warnings
- Fix a bug affecting warning options (e.g.
dolmen --warn=+all
triggered an uncaught exception that is now fixed)
- Fix bug in SMTLIB syntax (v2.6 and poly), where the define-funs-rec syntax construction expected an open paren at the end instead of a closing paren
- Complete the typing of alt-ergo's builtins PR#89
- Added exhaustivity and redundant pattern matching analysis (redundant patterns trigger a warning, whereas inexhaustive pattern matching trigger a typing error) part of PR#89
- Removed the typing of real and extended bitvector literals from the Float theory. These are not part of the FP specification, so it's better for Dolmen to be strict. Additionally, dependengin on the order of theories, they could shadow the proper typing of such literals and result in bogus warnings/errors PR#79 (see also Issue#43 Issue#74)
- Fixed the handling of the
reset
andreset-assertions
commands of smtlibv2.6. Previsously reset was ignored, and reset-assertions was treated as reset (meaning that any set-logic were erased). These two commands should now be correctly implemented in the typing loop. PR#80 - Added a warning for multiple set-logics PR#82
- Added a hint to suggest a missing theory when a literal is unbound. PR#81
- Added proper abstractions for names and paths. Names are used instead of strings for parsed identifiers (Id.t), while Paths are used instead of strings for typed identifiers (Expr.id). This results in a speedup on some smtlib problems because indexed identifiers no longer need to be encoded and then split.
- Added to Dolmen a custom implementation of Radix tries for a better indexation of strings. This results in signifcant speedup on large problem.
- Added some convenience modules for testing and profiling (Timer and Stats)
- The pipeline now delegates the task of printing backtraces for excpetions to the caller/finally argument of the run function
- the
Dolmen_loop
library now has an added dependency onpp_loc
(used for the source input printing) - updated version bounds on
cmdliner
andpp_locs
- The official github release now provides access to
already built binaries for
dolmen
anddolmenls
, for linux (ubuntu) and macos - The LSP server has been updated to depend on
linol~0.2
- Smtlib2 let-bindings were treated as sequential, but are
now treated as parrallel as specified by the spec;
i.e. the following is now correctly rejected:
(let (x 0) (y x) (...))
- Added support for higher order, including tptp's THF and Zf
- Optimized some corner cases of the typechecker to avoid exponential blowups
- The interface of the
Expr
module has changed to support higher-order - Additionally, there is now proper support for type aliases
(which are expanded on demand as necessary), in
Expr
- There is now a new typechecker module exposed as Thf for typing higher order expressions
- Added a functorized typechecker for all language supported by Dolmen
- Added a LSP server for all language supported by Dolmen
