More current [https://www3.hhu.de/stups/downloads/prob/tcltk/nightly/ nightly integration releases] are also available [[#Nightly Builds| below]].
=== Nightly Builds ===
These releases are not stored and usually updated every night.
 
There is also a [https://www3.hhu.de/stups/downloads/prob/tcltk/nightly/ProB_mac_os.x86_64_notarized.zip notarized version available ] for useful, e.g., for macOS Catalina.
More current [https://stups.hhu-hosting.de/downloads/prob/tcltk/nightly/ nightly integration builds] are also available.
These releases are usually updated every night and old versions are not stored.
 
Note for macOS users: Nightly builds of ProB are not signed or notarized, so macOS 10.15 and later (Catalina, Big Sur or Monterey, Ventura) will refuse to run them.
As a workaround, you will need to run <code>xattr -r -d com.apple.quarantine *</code> inside the ProB directory before launching ProB.
The stable and beta releases listed above are signed and notarized, so they will run without extra steps.
 
Automatically generated test [https://stups.hhu-hosting.de/internal/coverage/html/ coverage reports are also available].
They are usually updated once per week.

== Nightly Builds ==
== Java Requirements for B parser ==
The B parser of ProB requires Java 8 or newer. Java 11, 17, etc. are also fully supported.
ProB 1.9.3 is the last version to support Java 7. ProB 1.5.0 is the last version to support Java 6.


* You can download our [http://www3.hhu.de/stups/downloads/prob/tcltk/nightly/ nightly integration build from here].  Note: on Windows you will need [https://www.activestate.com/products/activetcl/downloads/ Tcl/Tk 8.6.6 or newer] to use the regular version of ProB (we currently also provide a version compiled for Tcl/Tk 8.5.x using an older SICStus Prolog version). On macOS Monterey you should use Tcl/Tk 8.6.x or newer. On new macOS systems (Catalina, bigSur or Monterey) you will also need to run <tt>xattr -rc *</tt> inside the ProB directory before launching ProB. Notarized versions are available for stable or beta releases above (Note: when you first start ProB you need an internet connection so that the macOS Gatekeeper can verify the signature.) Also, Tcl/Tk has a bug under Catalina: for the main menu to work you first need to click into another window and then reselect ProB's main window.

ProB Tcl/Tk requires an installation of Tcl/Tk 8.5 or Tcl/Tk 8.6. The command-line tool probcli does <b>not</b> require this.


=== Tcl/Tk on macOS ===
=== Tcl/Tk on macOS ===
Note: for macOS (until bigSur) you may have to install [http://www.activestate.com/activetcl/downloads/ the ActiveTcl version of Tcl/Tk] (the distribution provided by Apple is typically broken, e.g., after opening a file using the standard file selection dialog some versions crash).
Important note: macOS comes pre-installed with a version of Tcl/Tk which is broken.
However, even the version of Active Tcl/Tk on Mac can be quite unreliable and prone to crashing; for example version [http://bugs.python.org/issue15853 8.5.12 has a serious bug related to copying text], see also [http://sourceforge.net/tracker/?func=detail&aid=3555211&group_id=12997&atid=112997_type here]).
This may result in the display of unreadable <b>black windows</b> or crashes in the standard file dialogs.
This issue has been fixed in version 8.5.13 or later.
There are various options to install Tcl/Tk:
* with Homebrew using the [https://formulae.brew.sh/formula/tcl-tk tcl-tk formula]
* with [https://ports.macports.org/port/tcl/ MacPorts]
* use the  [http://www.activestate.com/activetcl/downloads/ ActiveTcl version of Tcl/Tk]
You should probably start ProB using the <tt>StartProB.sh</tt> script: it will auto-detect Tcl/Tk versions and set the SP_TCL_DSO environment variable.
Below are more details:


Note: on macOS Catalina or later the Tcl/Tk menu bar is sometimes not working. Switching to another application and then back to ProB seems to solve the problem.
==== Tcl/Tk from Homebrew or MacPorts ====
If you see the message "<tt>macOS 11 or later required !</tt>"  in the terminal when launching <tt>prob</tt> you should re-install Tcl/Tk as described above.


On macOS Monterey you should use Tcl/Tk 8.6.9 or later, as version 8.5 no longer seems to work correctly (e.g., text views are black).

==== Other Notes ====
Note: on macOS Catalina or later the Tcl/Tk menu bar is sometimes not working. Switching to another application and then back to ProB seems to solve the problem.
If you see the message "<tt>macOS 11 or later required !</tt>"  in the terminal when launching <tt>prob</tt> you should re-install Tcl/Tk as described above.

Latest Release

Below are links for downloading the latest stable release of probcli (the command line version of ProB) and ProB Tcl/Tk (ProB with a graphical user interface written in Tcl/Tk). Note: please use the provided start scripts (StartProB.sh or StartProBWin.bat) to start ProB. The list of changes can be found in the ProB release history.

Details of the ProB Licence can be found here. ProB is free to use and open source. For commercial support contact Michael Leuschel. In particular, we can provide access to the validation report for using ProB as a tool of class T2 or T3 within the European norm EN50128.

Homebrew Tap (not yet updated)

macOS 10.14 (Mojave) or newer, Tcl/Tk (see below), Java 8 or newer (see below), Graphviz (see below)

The B parser of ProB requires Java 8 or newer. More details are available below.

The Graphical User Interface of ProB Tcl/Tk requires Tcl/Tk 8.5 or 8.6. More details are available below. The default Tcl/Tk on macOS is broken and will result in black windows, and you have to install another version of Tcl/Tk. All releases include the command-line version probcli which does not require Tcl/Tk.

Releases are compiled for the x86_64 architecture (64-bit Intel). macOS releases of ProB 1.12.0 and later also support aarch64 (64-bit ARM/Apple Silicon). The last version built for x86 (32-bit Intel) is ProB 1.8.0 (see prior versions). If you are using an unsupported architecture or system, you may still be able to run ProB from source.

Note that: on macOS you still have to right-click on the application and use "Open", even though ProB Tcl/Tk (and probcli and all libraries) are signed and notarized.

Latest Beta Release

The latest beta release is 1.12.0-beta2 (which is older than the current final release). An official beta release always passes all of ProB's tests. However, we do not follow the stringent checklist for final releases (e.g., checking SICStus Prolog Spider warnings, checking coverage and additional manual UI tests). Also, we do not store coverage reports and other information necessary for T2 certification.

Nightly Builds

More current nightly integration builds are also available. These releases are usually updated every night and old versions are not stored.

Note for macOS users: Nightly builds of ProB are not signed or notarized, so macOS 10.15 and later (Catalina, Big Sur or Monterey, Ventura) will refuse to run them. As a workaround, you will need to run xattr -r -d com.apple.quarantine * inside the ProB directory before launching ProB. The stable and beta releases listed above are signed and notarized, so they will run without extra steps.

Automatically generated test coverage reports are also available. They are usually updated once per week.

Sourcecode

You can download the latest Prolog sourcecode snapshot from: https://stups.hhu-hosting.de/downloads/prob/source/

The source code for the ProB parsers (B, LTL, ...) can be obtained from: https://github.com/hhu-stups/probparsers

Prior Versions

Prior Versions of ProB going back to 1.3.1 are available for download here. If you are interested in still earlier releases, please have a look at the Download directory.

Other ProB tools

ProB Jupyter Kernel

You can now create Jupyter Notebooks in B using the ProB Jupyter kernel. Downloads, instructions, and source code can be found on its own page.

You can try out the ProB Jupyter kernel in your browser without installing it first. Note that notebooks are not saved permanently in this online version! To keep your notebooks, you must download them before closing the page.

ProB for Rodin

To install ProB for Rodin, first download a current version of Rodin (e.g., Rodin 3.8). Inside Rodin, choose Help -> Install New Software and choose the pre-configured ProB update site.

More detailed installation instructions and a brief tutorial are available.

ProB2-UI (based on JavaFX)

Version 1.2.1 of the new JavaFX-based ProB2-UI is available. See the release history for what's new. You can use these stand-alone versions which come bundled with the right Java runtime environment:

You can also download a multi-platform jar, which works Java 11 or later (and with Java 8 versions which have JavaFX included) on all platforms (Windows, macOS, Linux).

Details about new features and improvements can be found in the release history, along with download links for older versions.

Snapshot builds of the current development version of ProB2-UI (1.2.2-SNAPSHOT) are also available:

The source code for ProB2-UI is available at https://github.com/hhu-stups/prob2_ui and can be built by following these instructions.

The underlying ProB Java API of ProB2-UI (aka the ProB 2 kernel) is available to Java developers via Maven Central. Its source code can be obtained from: https://github.com/hhu-stups/prob2_kernel.

macOS issues

When you run the macOS app for the first time, you might have to open the app twice for ProB 2 UI to start properly. This should only happen once.

The ProB 2 UI macOS app releases are signed and notarized, so they should run without issues on current macOS versions. However, the multi-platform jar and snapshot app builds are not signed or notarized, so newer macOS versions will refuse to run them or say that the application is damaged. As a workaround, right-click the app, select "Open", and confirm the security dialog. If the dialog still doesn't give you an option to open the app, click "Cancel" and do the same thing again.

To run the multi-platform jar on macOS, we recommend using Java 15 or later. Older Java/JavaFX versions may lead to an incorrect system font resulting in gibberish text display. Alternatively, use the macOS app build, which comes with Java 17 and does not have this issue.

Editor Support

Java Requirements for B parser

The B parser of ProB requires Java 8 or newer. Java 11, 17, etc. are also fully supported. ProB 1.9.3 is the last version to support Java 7. ProB 1.5.0 is the last version to support Java 6.

You can install a Java Runtime Environment (JRE) from various sources, such as Eclipse Adoptium, Azul Zulu, or your system package manager.

Note: on some systems (macOS) you may have to install the full Java Development Kit (JDK), and not just the JRE, so that Java 8 becomes available to the command-line tools. Type java -version to check which version is used by default for command-line tools; see also this discussion on StackOverflow. In case you have trouble starting the Java parser you can now set the JAVA_PATH preference of ProB to point to the java tool (or java.exe on Windows).

To check whether ProB can correctly use its Java parser you can type the following (using probcli.exe on Windows):

probcli -version -v

This will try and start the parser and obtain the parser version. In case Java is not correctly installed you should get an error message. If you see the error message

Unsupported major.minor version 52.0

this means you do not have Java 8 or newer installed. You can try setting the path to the correct java version by setting the JAVA_PATH preference as follows:

probcli -p JAVA_PATH path/to/java -version -v

Tcl/Tk Requirements for ProB Tcl/Tk

ProB Tcl/Tk requires an installation of Tcl/Tk 8.5 or Tcl/Tk 8.6. The command-line tool probcli does not require this.

Tcl/Tk on macOS

Important note: macOS comes pre-installed with a version of Tcl/Tk which is broken. This may result in the display of unreadable black windows or crashes in the standard file dialogs. There are various options to install Tcl/Tk:

You should probably start ProB using the StartProB.sh script: it will auto-detect Tcl/Tk versions and set the SP_TCL_DSO environment variable. Below are more details:

Tcl/Tk from Homebrew or MacPorts

You can install a newer Tcl/Tk (e.g., 8.6.12) using Homebrew or MacPorts. Note: In the earlier release 8.6.11 file open and file save dialogs will not work. For Homebrew the command to install thetcl-tk formula is:

 brew install tcl-tk

However, as the location of the libraries is not standard, you have to define the variable SP_TCL_DSO. The StartProB.sh script should set SP_TCL_DSO automatically. You can also define and export this variable yourself before starting ProB from the Terminal by typing this (you may have to adapt the link if you are using another version of Tcl/Tk):

export SP_TCL_DSO=/usr/local/Cellar/tcl-tk/8.6.12/lib/libtcl8.6.dylib

If you have uses MacPorts the path is probably /opt/local/lib/libtcl.dylib. You can also set the variable by adding -DSP_TCL_DSO=/usr/local/Cellar/tcl-tk/8.6.12/lib/libtcl8.6.dylib to the command starting ProB. You may also have to install tk-table package yourself (it is bundled with Active Tcl).

Active Tcl

The the ActiveTcl version of Tcl/Tk is automatically recognised by ProB and you do not have to set SP_TCL_DSO.

However, in Active Tcl/Tk 8.6 on macOS the double click in the "Operations View" or other views is not working correctly. You have to hit the RETURN key in the "Operations View" or right-click on an operation and select "Perform ..." to execute an operation until this is fixed. The older ersion 8.5.12 has a bug related to copying text, see also here).


Other Notes

Note: on macOS Catalina or later the Tcl/Tk menu bar is sometimes not working. Switching to another application and then back to ProB seems to solve the problem. If you see the message "macOS 11 or later required !" in the terminal when launching prob you should re-install Tcl/Tk as described above.

Tcl/Tk on Windows

We currently provide two downloads of ProB, one for Tcl/Tk 8.6 (which we recommend) and a version for Tcl/Tk 8.5. You can use for example the ActiveTcl releases. Note: For the 64 bit version of ProB for Windows, you have to install the 64 bit Tcl/Tk 8.5 version! ProB 1.12 (currently available as nightly build) works with both Tcl/Tk 8.5 and 8.6. You may have to point the environment variable SP_TCL_DSO to the correct DLL before starting ProB. For Tcl/Tk 8.5 this is typically base-tcl8.5-thread-win32-x86_64.dll. You can either go to System -> Settings -> Advanced -> Environment Variables or use the setx command for this:

Tcl/Tk on Linux

On Linux you can typically install Tcl/Tk using sudo apt-get install tcl8.5 tk8.5.

On very recent Linux systems (such as Ubuntu 20.04) you may want to download (and compile) Tcl/Tk 8.5 or use packages from earlier releases.

On Linux OpenSuse (12.3) you may have to perform the following for ProB to work:

ln -s /usr/lib/libtk8.5.so /usr/lib/libtk8.5.so.0
ln -s /usr/lib/libtcl8.5.so /usr/lib/libtcl8.5.so.0

Also, some of the feature require the table extension, which can be installed like this:

sudo apt install tk-table

Finally, support for .png ANIMATION_IMG declarations requires the Img package:

sudo apt install libtk-img

Graphviz Requirements

If you wish to view various visualizations generated by ProB Tcl/Tk or probcli you will need GraphViz. ProB may use the command-line tool dot and a dot-file viewer such as dotty (optionally in ProB Tcl/Tk).

On Mac, the only working application to view dot files is graphviz-gui by MacPorts. To install the application do this

  • sudo port install graphviz-gui

The viewer can now be found in /Applications/MacPorts/Graphviz.app (you may have to set the ProB graphical viewer preference dot_viewer to this path). Some ProB commands work directly with the command-line tool dot which you can install with MacPorts like this:

  • sudo port install graphviz

On Mac you can now install the latest version of Graphviz using HomeBrew:

1. brew uninstall graphviz
2. brew install graphviz --with-gts
3. brew link --overwrite graphviz

Step 1. is optional; you only need to use it if you have a prior version of Graphviz installed. Step3 links the binaries to /usr/local/bin. This is probably better than using the older version from Pixelglow.

On macOS you should probably select Preferences -> Graphical Viewer -> PDF within ProB Tcl/Tk, as currently all GraphViz viewer applications seem to crash on current macOS systems.

You can also manually set the DOT (path_to_dot) preference if ProB cannot find the Graphviz dot binary you have installed.

Note: if you wish to use the fast rendering for large state spaces in ProB 1.7.x, you need the sfdp tool of GraphViz (ideally version 2.28 or newer with the triangulation library; when installing using brew use the option --with-gts; see the section below). As of version 1.8.1 ProB only uses the dot binary for command-line tasks (and not sfdp anymore), making use of the -Ksfdp option.
