CLIG(1)			      Programmer's Manual		       CLIG(1)

NAME
       ::clig::Int - declare an option with parameters of type int

SYNOPSIS
       package require clig
       namespace import ::clig::*
       setSpec db

       Int -opt varname usage [-c min max] {[-d default ...]  | [-m]} [-r rmin
       rmax]

DESCRIPTION
       The Int command declares -opt to have zero or more  integer  arguments.
       The  parameters variable and usage as well as the options -c, -d and -m
       are described in clig::String(n).

       -r     instructs the parser to check that arguments given to  -opt  are
	      within  the inclusive range between rmin and rmax.  Special val‐
	      ues for rmin and rmax are -oo and oo" denoting negative and pos‐
	      itive infinity thereby not constraining the parameters of -opt.

       WARNING:	 The implementation of option -d is currently incomplete inso‐
       far, as the specified default values are not checked by clig, i.e.  the
       following would go unnoticed:

	      -d 1.0 -r 500 600

       In  this	 case,	if  option is not on the command line, the clig parser
       will set variable varname for its caller to the out-of-range value 1.0.
       (Maybe this is a feature?)

       Example use of Int:

	 Int -ind indices {list of indices to use} \
	     -r 0 99  \
	     -d 0 10 20 30 40 50 60 70 80 90 \
	     -c 1 oo

PARSER RESULT
   tcl
       Within a Tcl-script, the parser will set the variable with name varname
       in the stack-frame of its caller if and only if option -opt is found on
       the command line or has a default value.

   C
       The  structure returned by the parser contains the slots varnameP, var‐
       name and varnameC.  The slot varnameP will be set to a non-zero	value,
       if  and	only  if the option -opt is found on the command line or has a
       default value. Otherwise it will be 0. The slot varnameC will be set to
       the number of arguments found for -opt.	If the number of arguments for
       -opt is allowed to be greater than 1, slot varname has type int*,  oth‐
       erwise it has type int.
