Using the Command-Line Version of ProB: Difference between revisions

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.

Conventions used

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.

Command-line Arguments for ProB Tcl/Tk

Note that the stand-alone Tcl/Tk version also supports a limited form of command-line preferences:

• FILE (the name/path of the file to be loaded)
• -prefs PREF_FILE (to use a specific preferences file, rather than the default ProB_Preferences.pl in your home folder)
• -batch (to instruct ProB not to try to bring up windows, but to print information only to the terminal)
• -selfcheck (to run the standard unit tests)
• -t (to perform the Trace Check on the default trace file associated with the specification)
• -tcl TCL_Command (to run a particular pre-defined Tcl command)
• -mc (to perform model checking)
• -c (to compute the coverage)
• -ref (to perform the default trace refinment check)

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.

Options

-mc <nr>

Description

model check; checking at most <nr> states

Example

 probcli my.mch ...

-no<x>

Some probcli examples

To load a file My.mch, setup the constants and initialize it do:

probcli -init My.mch

To load a file M.mch, setup the constants, initialize and then check all assertions with Atelier-B's default values for MININT and MAXINT and an increased timeout of 5 seconds do:

probcli -init -assertions -p MAXINT 2147483647 -p MININT -2147483647 -p TIME_OUT 5000 M.mch
