CHANGES.md.html · dolmen_loop 0.7

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 and reset-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 on
pp_loc (used for the source input printing)
updated version bounds on cmdliner and pp_locs

The official github release now provides access to
already built binaries for dolmen and dolmenls,
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) (...))

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
