# This file implements the IRK CTCP TCL protocol:

namespace eval ::irk {

    # This procedure sets up a safe interpreter for the channel in which
    # the CTCP TCL action occurs:

    proc setupInterp {token chan} {
        variable state

            catch {interp delete ${token}${chan}}

            safe::loadTk $state($token,$chan,interp)
        }
        if {![interp exists ${token}${chan}]} {
            set state($token,$chan,interp) [safe::interpCreate ${token}${chan}]
            safe::loadTk $state($token,$chan,interp)
        }
    }

    # This procedure dispatches the Tcl command embedded within the
    # CTCP TCL action to the associated interpreter:

    proc RECV,CTCP,TCL {token nick user comm dest action rest} {
        variable state

        puts stderr "Tcl command is: $rest [llength $rest]"
        setupInterp $token $dest
        interp eval $state($token,$dest,interp) [::join $rest]
    }

    # This procedure dispatches the Tcl command embedded within the
    # CTCP TCL action for local execution on the issuer's side:

    proc RECV,CTCP,TCL,LOCAL {token nick user comm dest action rest} {
        variable state

        puts stderr "Tcl command is: $rest [llength $rest]"
