how to pass parameter while sourcing script file

Question

i was sourcing a tcl script file and could not pass the parameter. ie.

source test.tcl param1 param2

where in test.tcl, it uses param1 and param2 to print as string

Note: I need to source tcl script only.. Not any other

puts "param1                       :  $1"
puts "param2                       :  $2"

You can set argv:

set origargv $::argv
set ::argv [list -param1 x -param2 y]
source myscript

The sourced script can access the parameters from argv as usual.

I'd use a try…finally to restore the arguments… if necessary. I usually don't write my scripts to need that; most of my code files just declare procedures, namespaces and classes, and have no meaningful arguments.
