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 values for rmin and rmax are -oo and oo" denoting negative and positive infinity thereby not constraining the parameters of -opt.

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

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
