cmdline argument parsing using tcl? - tcl

Question

I am trying to pass the parameters to Spirent test center tool using command line arguments, where I am passing slots, ports, frame size and load. I want to store the Slots and ports in array, where number of ports are dynamic.
I tried simple code with cmdline which can handle fixed ports
package require cmdline
set parameters {
{s.arg "" "Slot"}
{p.arg "" "Port"}
{l.arg "100" "Load"}
{f.arg "256" "Framesize"}
{debug "Turn on debugging, default=off"}
}
#set option(l) 100
set usage "- A simple script to demo cmdline parsing"
if {[catch {array set options [cmdline::getoptions ::argv $parameters $usage]}]} {
puts [cmdline::usage $parameters $usage]
} else {
parray options
}
#puts [array get options]
puts $options(l)
puts $options(f)
script Output:
C:\Tcl\bin>tclsh opt.tcl -s 1 -f 128
options(debug) = 0
options(f) = 128
options(l) = 100
options(p) =
options(s) = 1
100
128
Here I would like to pass all the ports for each slots onetime ,
tclsh opt.tcl -s 1 2 -p 11 12 13 14 -f 256 -l 100
Where slots are 1 and 2 and ports in each slot are 11,12,13,14 and need to create array of slot and ports. Could you please suggest some method to achieve this.

Answer 1

Try
tclsh opt.tcl -s "1 2" -p "11 12 13 14" -f 256 -l 100
It works for me under Windows 10, at least. The thing is that the lists of slots and ports need to be one value each: the quotes ensure that.

Answer 2

I tried the following method with some corrections:
set arglen [llength $argv]
while {$index < $arglen} {
set arg [lindex $argv $index]
#puts $arg
switch -exact -- $arg {
-s {
set args($arg) [lindex $argv [incr index]]
set slot($y) $args($arg)
incr y
}
-p {
set args($arg) [lindex $argv [incr index]]
set port($z) $args($arg)
incr z
}
-l {
set args($arg) [lindex $argv [incr index]]
global Load
set Load $args($arg)
}
-f {
set args($arg) [lindex $argv [incr index]]
set frameLength $args($arg)
}
}
incr index
}
Command to run:
C:\Tcl\bin>tclsh l1.tcl -s 1 -p 11 -p 12 -l 10 -f 1
