* Added temporal language elements to grammar * Integrated behavioral clafer grammar and implemented desugaring of temporal expressions, transitions and modalities. * Adjusted grammar; Finished implemented desugaring rules; Fixed sugaring of some expressions; Added simple test runner 'desugartests.sh' in test/positive/ * Implemented Alloy-Ltl model code generator * Refreshed grammar generated code and added missing files to clafer.cabal * AlloyLtl generator: fixed mutable clafer cardinalities * Improvments in AlloyLtl generator: created root clafer which is umbrella for all top level clafer relations. Changed time binding in constraints. * Updated gramamr with new pattern expressions and updated pattern ltl encodings * removed duplicate clafer names from test cases * ClaferBinding = Maybe UID Pass GenEnv instead of ClaferArgs around removed ClaferArgs from GenCtx * change soft constraint from `(...)` to `assert [...]` * Added lonce temporal pattern * Fixed parent constraint; fixed first local time instance declaration; fixed group cardinality constraint * inheritance of mutability * regen parser * fixed syntax of transitions/removed async transition --> next step (X) -->> many steps (U) * removed FinalConstraint, added IClaferModifiers and their inheritance, html rendering of temp modifiers, root clafer initial and final, * fixed warnings * fixed test cases using set intersection (& to **) * fixed changing & to ** * initial and final inherited correctly (were "flipped") * added the missing rules to HTML generator (fixed non-exhaustive patterns) * html rendering of transition on clafer decl and the remaining patterns * moved PowerWindow models to experimental they use redefinition, which is not supported yet * fixed "before" pattern was "between" by mistake * updated all tmp positive test cases, moved history to experimental removed redundant test cases (clones) * updated regressions for xml, html, and dot * updated regressions for alloy and js * fixed test case (broken comment) * added temporal keywords to reserved keyword list * automatic selection of static of dynamic Clafer subset for Alloy generation. Choco and Python outputs only for static subset. * fixed test suites for default Alloy42 mode * updated Python regressions and few others * removed validation is NoCompilerResult, fixed XML Schema * updated XML validator * bumped version to 0.4.0 * fixed description in readme * Fixed: root level constraint issues, mutable subclafer cardinality facts, restricted network package version in clafer.cabal * Allow using AlloyLtl for static subset of Clafer Must provide two modes: 4.1 or 4.2 + whether LTL or not (default) * code formatting and error msgs * fixed Int generation need to check istop otherwise we get @r_integer instead of Int generated * update regression * Updated to work with the new version of custom BNFC tool * updated missed old Absclafer import * create correct root in UID->IClafer map, * scope computation: multiply by trace length for mutable clafers renamed `fixed_scope` to `trace_len` * Fixed issue #1: after-until scope was not properly parsed * Fixed translation of WeakUntil operator in AlloyLtl ouput * added assertion generation to AlloyLtl * Fixed assertions in AlloyLtl * adapted the new python generator to behavioral * ported group card. fix to AlloyLtl -- TODO: need to include time stamps genParentSubrelationConstriant (needed for proper inheritance from nested abstract clafers) * fixed --trace-len default to 10 * preliminary fix for quantifier expression in form `all x : A.B.C | x...`. Added test cases. however, for the resulting Alloy code, Alloy complains that "Analysis cannot be performed since it requires higher-order quantification that could not be skolemized." * moved redefinition test case to failing it is not implemented yet * Fixed desugaring of lonce pattern with before scope * added a missing assertion to tmp_clafertransitions02.cfr * Added parenting constraint that prevents subgraphs which are not connected to root * updated test cases * updated test case for eventually constraint * updated test case and commented constraint giving error * testcase for history constraint * TrafficLight Update * test for commit * added to regression testing * AlloyLtl changes: Added local_first function and switched constraints to using it; Added several constraints to prevent subinstances from reappearing and changing parents during a trace. * Fixed parenting constraint in alloyltl generator * fixed Suite.Positive * Deferred initally desugaring until after analysis (generator stage), which fixed alloy output of initially constraint * rebuilt XsdCheck * fix build on GHC 7.10.1, remove warnings * Fixed bFoldlOr to have a more canonical name and implementation This is mostly to test my build, test and Haskell setup + commit rights * refactored the header of the AlloyLtl generator Tried to make both the generator and the alloy output more readable. Primarily wanted to get into the code a bit. * Updated Alloy Ltl encodings to the latest proposal by A.Cunha * Partially fixed transitions issue #9. Alloy output now compiles, but needs extra fining * Resolved issue when reference to mutable parent was not joined with correct t relation (it was getting t primes although it needed t) * Partly fixed issue #3: local variable declarations are now allowed - there is still issue with declarations in top level constraints. Also fixed parenting constraints, that prevent clafers having subclafers if they have no parents. * Removed leftover trace call * Removed unnecessary domain restrictions on State and replaced declaration 'one t:' to 'let t=' * Added empty function root clafer adjustment * Added finaltarget and finalref modifiers for references. Desugaring needs more work. * Fix desugaring of reference expressions with modifiers * Move inline state declarations to outside file to be embedded using template haskell * Remove _mutable field from IClafer; Use final modifier instead to detect mutability * Remove debugging trace printing from Inheritance Resolver * Add state suffix to mutable reference clafers * Generate top level clafer ids without 'r_' relation prefix * Remove leftover debugging traces * Fix alloyltl encoding of initial modifier * remove Python mode and skip-goals option, remove .x and .y files, upgrade to LTS-5.15 * fixed test cases. "X" is a keyword in bClafer * GHC version compatibility for ErrM.hs * fixed grammar for min, max, and if/then/else. Fixed a test case 'X' is reserved All test suite models now compile * updated test case 'objectivesMinMax' - 'X' is a reserved keyword * Ensure that instance occurs at least once as child of parent instance * only produce Choco output for static subset * add test cases * fixed test/experimental/tmp_PowerWindowDesignModel.cfr * commented out or removed failing temporal assertions * added temporal regressions for reference * fix to be , and to be * warning cleanup, missing pattern matches, linting * updated regressions * styling of temporal keywords, updated regressions * compile temporal models to .tmp.als, and static models to .als so that ClaferIG can distinguish * save .tmp.als files as .als for backwards compatibility * Release 0.5.0 * add stateTrace.als to datafiles so that it's present in sdist. Otherwise cabal install does not work
