package dolmen_lsp

v0.8

UI

• Add a minimal reporting style accessible via the --report-style option. When used, the dolmen 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)

Model verification

• Added model verification. This currently supports all builtins, except for String/Regular expressions.

Parsing

• 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 a define-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)

Typing

• 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)

Loop

• 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)

v0.7

UI

• 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)

Parsing

• 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

Typing

• 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

API

• 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

v0.6

Release

• 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

Bugfixes

• 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) (...))

Features

• Added support for higher order, including tptp's THF and Zf

• Optimized some corner cases of the typechecker to avoid exponential blowups

API

• 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

v0.5

Additions

• Added a functorized typechecker for all language supported by Dolmen

• Added a LSP server for all language supported by Dolmen
