Press Return to continue:invalid command name ""
while executing
"[tutstack::connect "New York"]"
(file "main.tcl" line 6)
代码：
package provide weather 1.0
package require Tcl 8.5
package require Expect
namespace eval ::tutstack {
}
proc ::tutstack::connect {arg1} {
puts "got $arg1"
spawn telnet rainmaker.wunderground.com
set telnet $spawn_id
expect -nocase "Press Return to continue:"
send "$arg1"
}
主要的：
lappend auto_path /home/thufir/NetBeansProjects/spawnTelnet/telnet/api
package require weather 1.0
[tutstack::connect "New York"]
我已经尝试过没有成功的变化。send "\r"
预期结果：
thufir@dur:~/NetBeansProjects/spawnTelnet/telnet$
thufir@dur:~/NetBeansProjects/spawnTelnet/telnet$ telnet rainmaker.wunderground.com
