The command-line version of ProB offers many of the feature of the standalone Tcl/Tk Version via the command-line. As such, you can run ProB from your shell scripts or in your Makefiles.
The following conventions are used in this guide:
| <replaceme> | All values that should be replaced with some value are shown withing < > |
| line breaks | Command synopsis for command may be broken up on several lines. When typing commands enter all option on the same line. |
probcli [--help] <filename> [ <options> ]
Note that the stand-alone Tcl/Tk version also supports a limited form of command-line preferences:
However, the comand-line version of ProB, called probcli, provides more features. It also does not depend on Tcl/Tk and can therefore be run on systems without Tcl/Tk.
Description
| model check; checking at most <nr> states |
Example
probcli my.mch ...
Description
| restrict errors reported by model checking with <x>=dead,inv,goal,ass
-nodead : do not report deadlocks -noinv : do not report invariant violations -nogoal : do not stop if a state satisfying the GOAL predicate has been found -noass : do not report assertion violations |
Example
probcli my.mch -mc 1000 -nodead -nogoal

Example
probcli my.mch -cbc all
Description
| constraint-based deadlock checking (also use -cbc_deadlock_pred PRED) |
Description
Example
probcli my.mch -cbc_deadlock_pred "n=15"
Description
| raise error if mc finds counter example or trace checking fails |
Example
probcli my.mch -t -strict
Description
| expect error to occur (<ERR>=cbc,mc,ltl,...)
Tell ProB that you expect a certain error to occur. Mainly useful for regression tests (in conjunction with the -strict option). |
Example
probcli examples/B/Benchmarks/CarlaTravelAgencyErr.mch -mc 1000 -expcterr invariant_violation -strict
Description
| random animation (max Nr steps) |
Animates the machine randomly, maximally Nr of steps. It will stop if a deadlock is reached.
Example
probcli my.mch -animate 100
Description
| check if animation steps are deterministic |
Checks if every step of the animation is deterministic (i.e., only one operation is possible, and it can only be executed in one possible way as far as parameters and result is concerned). Currently this option has only an effect for the -animate <Nr> and the -init commands.
Example
probcli my.mch -animate 100 -det_check
Description
| check if animation steps are deterministic |
Checks if the SETUP_CONSTANTS step is deterministic (i.e., only one way to set up the constants is possible). Currently this option has only an effect for the -animate <Nr> and the -init commands.
Example
probcli my.mch -init -det_constants
Description
| save animation history to a file |
Save the animation (or model checking) history to a text file. Operations are separated by semicolons. The output can be adapted using the -his_option command. See also the -sptxt command.
Example
probcli -animate 5 -his history.txt supersimple.mch
Additionally we can have the initialised variables and constants:
probcli -animate 5 -his history.txt -his_option show_init supersimple.mch
And we can have the values of the variables in between:
./probcli -animate 5 -his history.txt -his_option show_init -his_option show_states supersimple.mch
Description
| interactive animation |
After performing the other commands, ProB stays in interactive mode and allows the user to manually animate the loaded specification.

probcli my.mch -i
Description

Example
probcli my.mch -p CLPFD TRUE -eval

Description
| Set preferences from preference file <FILE>. The file should be created by the Tcl/Tk version of ProB; this version automatically creates a file called ProB_Preferences.pl. For more information about preferences please have a look at Preferences |

Example

Description
| refinement check against previous saved state space |
Example
probcli my.mch ...
Generate test cases for the given specification. Each test case consists of a sequence of operations resp. events (a so-called trace) that
The user can specify what requested operations/events are with the option -mcm_cover.
ProB uses a "breadth-first" approach to search for test cases. When all requested operations/events are covered by test cases within maximum length M, the algorithm will explore the complete state space with that maximum distance M from the initialisation. It outputs all found traces that satisfy the requirements above.
The algorithm stops if either
The required parameters are:
Example
probcli my.mch -mcm_tests 10 2000 "EndStateVar=TRUE" testcases.xml -mcm_cover op1,op2
generates test cases for the operations op1 and op2 of the specification my.mch. The maximum length of traces is 10, at most 2000 states are explored. Each test case ends in a state where the predicate EndStateVar=TRUE holds. The found test cases are written to a file testcases.xml.
Specify an operation or event that should be covered when generating test cases with the -mcm_test option. Multiple operations/events can be specified by seperating them by comma or by using -mcm_cover several times.
See -mcm-tests for further details.
