ProB can (as of version 1.6.1) be used to process Latex files, i.e., the command-line tool probcli scans a given Latex file and replaces certain commands by processed results.
Usage
A typical usage would be as follows:
probcli FILE -init -latex Raw.tex Final.tex
Note: the FILE and -init commands are optional; they are required in case you want to
process the commands in the context of a certain model.
Currently the probcli Latex commands mainly support B and Event-B models, TLA+ and Z models can also be processed but all commands below expect B syntax.
You can add more commands if you wish, e.g., set preferences using -p PREF VAL or run model checking --model-check.
The Latex processing will take place after most other commands, such as model checking.
You will probably want to put the probcli call into a Makefile, in particular when you want to generate dot graphics using ProB.
The distribution folder of ProB contains an example with a Makefile, producing the following file, which at the same time documents the core features:

Commands
The commands are described in the PDF document above.
Here is a short summary of some of the commands:
- \probexpr{EXRP} command takes a B expression EXPRas argument and evaluates it. By default it shows the B expression and the value of the expression. Example: \probexpr{{1}\/{2**10}} will be replaced by {1,1024}
- \probrepl{CMD} command takes a probcli REPL command CMD as argument and executes it. By default it shows only the output of the execution, e.g., in case it is a predicate TRUE or FALSE. Example: \probrepl{let DOM = 1..3}.
- \probtable{EXRP} command takes a B expression EXPRas argument, evaluates it and shows it as a Latex table.
- \probdot{DOT}{File1} command takes a B expression EXPRas argument, evaluates it as a graph and writes a dot file File1. You can provide a second File as argument, in which case dot is called to generate a PDF document.
- \probprint{EXRP} command takes a B expression or predicate EXPRas argument and pretty prints it.
- \probif{EXPR}{Then}{Else} command takes an expression or predicate EXPR and two Latex texts. If the expression evaluates to TRUE the first branch Then is processed, otherwise the other one Else is processed.
- \probfor{ID}{Set}{Body} command takes an identifier ID, a set expression Set and a Latex text Body, and processes the Latex text for every element of the set expression, setting the identifier to a value of the set.
