自动化测试之---Tcl事件驱动编程

 今天闲着无事，我之前的一些Tcl脚本翻出来，以下是一个Tcl事件编程的例子:

set done 0
set count 0
proc Reader {fd} {
    global done count
    if {[eof $fd]} {
        puts "eof $fd"
        set done 1
        close $fd
    } else {
        set buf [gets $fd]
        if {$buf != "" || 1} {
            puts $buf
            if {[regexp -nocase -- "^Reply from" $buf]} {
                incr count
            }
            if {$count == 5} {
                exit
            }
        }
    }
}

 

puts "Begin to ping, please waiting......"
set fd [open "|ping 10.11.2.85 -n 20"]
puts $fd
fconfigure $fd -blocking 0
fileevent $fd readable [list Reader $fd]
vwait done
