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.
