# mcrl2i(1)

Interpreter for the mCRL2 data language

## NAME

mcrl2i - Interpreter for the mCRL2 data language

## SYNOPSIS

**mcrl2i** \[*OPTION*\]... \[*INFILE*\]

## DESCRIPTION

Evaluate mCRL2 data expressions via a text-based interface. If INFILE is  present and if it contains an LPS or PBES, the data types of this specification  may be used. If no input file is given, only the standard numeric datatypes are  available. Stdin is ignored.The following commands are available to manipulate  mcrl2 data expressions. Essentially, there are commands to rewrite and type  expressions, as well as generating the solutions for a boolean expression. The  expressions can contain assigned or unassigned variables. Note that there are  no bounds on the number of steps to evaluate or solve an expression, nor is the  number of solutions bounded. Hence, the assign, eval solve commands can give  rise to infinite loops.\
   h\[elp\]                         print this help message.\
   q\[uit\]                         quit.\
   t\[ype\] EXPRESSION              print type of EXPRESSION.\
   a\[ssign\] VAR=EXPRESSION        evaluate the expression and assign it to the \
   variable.\
   e\[val\] EXPRESSION              rewrite EXPRESSION and print result.\
   v\[ar\] VARLIST                  declare variables in VARLIST.\
   r\[ewriter\] STRATEGY            use STRATEGY for rewriting.\
   s\[solve\] VARLIST. EXPRESSION   give all valuations of the variables in\
                                       VARLIST that satisfy EXPRESSION. VARLIST is of the form x,y,...: S; ... v,w,...: T.

## OPTIONS

- *OPTION* can be any of the following:

  - **-Q***NUM*, **--qlimit**=*NUM*

  limit enumeration of quantifiers to NUM variables. (Default NUM=1000, NUM=0 for  unlimited).

- **-r***NAME*, **--rewriter**=*NAME*

  use rewrite strategy NAME: 'jitty' jitty rewriting (default) 'jittyc' compiled jitty rewriting 'jittyp' jitty rewriting with prover

- **--timings**\[=*FILE*\]

  append timing measurements to FILE. Measurements are written to standard error  if no FILE is provided

- Standard options:

  - **-q**, **--quiet**

  do not display warning messages

- **-v**, **--verbose**

  display short intermediate messages

- **-d**, **--debug**

  display detailed intermediate messages

- **--log-level**=*LEVEL*

  display intermediate messages up to and including level

- **-h**, **--help**

  display help information

- **--version**

  display version information
