CLIG(1) Programmer's Manual CLIG(1)NAME
::clig::Flag - declare a flag (boolean, classic) option
SYNOPSIS
package require clig
namespace import ::clig::*
setSpec db
Flag -opt varname usage
DESCRIPTION
The Flag command declares an option without any parameters. The command
line parser merely checks for the existence of opt on the command line.
tcl
If parseCmdline finds opt on the command line, variable varname in the
caller's context is set to 1. If opt is not on the command line, the
variable is not set.
C
If opt is found on the command line the slot variableP in the structure
returned by the parser will be set to a non-zero value, otherwise it
will be 0.
Example use of Flag:
Flag -v verbose {verbose operation}
