$ java -jar circus2zcsp-ass-20160630.jarusage: java -jar circus2zcsp.jar spec.tex [spec1.tex [...]] [-d] [-v] [-V] Circus2ZCSP is a translator to link one (or more) Circus specification to its corresponding model in Z || CSP, which is sequentially model-checked by ProB. Options: -d,--verbose run in debug mode -v,--version show version -V,--Versions show detailed versions information For any problems, please contac <[email protected]> or <[email protected]> -

$ java -jar circus2zcsp-ass-20160630.jar -VCurrent Circus2ZCSP version: 0.3 ==> 0.1 This is the first release built on March 15th, 2016. It is capable of translating all constructs in the reactive buffer and the steam boiler cases. Limitations: 1. External choice of actions are only available to "prefixed" actions (such as basic actions, prefixing, guarded commands), and compound CSP actions of the se "prefixed" actions. 2. Parallel composition and interleaving for actions are not supported if bo th actions share variables in scope. 3. Operator template is not supported. 4. Reflexive-transitive closure (*) is not supported. ==> 0.2 This is the second release built on May 13th, 2016. It is capable of translating all constructs in the reactive buffer, the steam boiler cases, and the ESEL cas e. -------------------------------------- New ------------------------------------ 1. Add support of iterated parallel and interleaving of actions for the case if their actions have disjoint variables in scope 2. Add support of iterated parallel of processes ------------------------------------- Fixed ----------------------------------- 1. Add parenthesis around translated freetype constructor d~1: d.1 => (d.1) in c sp 2. The problem that freetype is not translated to CSP though this type is used i n the behavioural part ------------------------------------ Changed ---------------------------------- 1. The processing of u'=u (u - variables not in frame) in schema expression as a ction 1.1 if v' is included in its declaration part, then this v is regarded in fr ame 1.2 if v' is nto included in its declaration part (though v might be include d), then this v is regarded not in frame 2. The logic to include parent sections 2.1 use a stack to keep dependency order of all sections 2.2 assemble all sections into a big section according to their dependency o rder ----------------------------------- Limitations ------------------------------- 1. External choice of actions are only available to "prefixed" actions (such as basic actions, prefixing, guarded commands), and compound CSP actions of these " prefixed" actions. 2. Parallel composition and interleaving for actions are not supported if both a ctions share variables in scope. 3. Operator template is not supported. 4. Reflexive-transitive closure (*) is not supported. ==> 0.3 This is the third release built on June 30th, 2016. It is capable of translating all constructs in the reactive buffer, the steam boiler cases, and the ESEL cas e. -------------------------------------- New ------------------------------------ ------------------------------------- Fixed ----------------------------------- ------------------------------------ Changed ---------------------------------- 1. Check if a schema that corresponding a schema expression as action shall be an operational schema. ----------------------------------- Limitations ------------------------------- 1.
