This script running on my bot since yesterday morning and I've seen nothing!.. İ've tried with different language settings for hours then shared on here...
Error must be on your side!
I assume, you're using a txt editor which doesn't have Tcl support (Windows Notepad may be ?)

Code: Select all

if {[package vcompare [package present tls] 1.7] > 0} { 
    ::http::register https 443 [list ::tls::socket -autoservername 1] 
 } else { 
    ::http::register https 443 [list ::tls::socket -request 0 -require 1 -ssl2 0 -ssl3 0 -tls1 1] 
 } 
These lines should works if his tls 1.7.x or not.

Code: Select all

package require tls 1.6.4
should be newer than 1.6.4 ofcourse!

His error says: syntax error:
Tcl error [Google_TopNews]: error "syntax error" at line 1 character 0
"0 <--Error-- "
so, somehow,somethings broken the code lines/syntax when he tries to copy/paste on his editor or while he tries to edit settings. and it throws that unvisible character err...

This points me that his txt editor doesn't support Tcl syntax probably...
or copy/paste failor..


or another possibility is; his bot is soo whinie and doesn't like to see bare 0 in that line! maybe his bot wants to see that 0 between quotes in there.. so;

Code: Select all

if {[package vcompare [package present tls] 1.7] > "0"} { 
instead:

Code: Select all

if {[package vcompare [package present tls] 1.7] > 0} { 
?

my bot, she doesn't care that much....
Life iS Just a dReaM oN tHE wAy to DeaTh

Dear Scripters.
When I restart my BOT, It shows NEWS only ONCE, but after that it starts to show this Error, Again I restart it shows NEWS, after that again shows this Error in DCC Chat.

Code: Select all

[07:54:00] wrong # args: should be "tls::socket ?options? host port"
Tcl error [Google:News]: error "syntax error" at line 1 character 0
"0 <--Error-- "
Actull line in tcl is.

Code: Select all

if {[package vcompare [package present tls] 1.7] > "0" } {

I have tried with both -> 0 and -> "0"
With "0" it shows News Once. but with 0 It does nothing just ERROR.
Please help.

Imho, the trouble is that the https registration is made globally. If you have another script which uses https and unregister it after using it, this script won't work anymore.

Solution: register the https when needed (in getit and getRealLink proc).

Note that the tinyurl proc may not work as it's set to use http and not https

To do it clean, the script must be rewritten to have an unique proc to the the http queries

Small try: edit the httpsregister procedure and add the package require tls in it:

Code: Select all

proc httpsregister {} {
   package require tls
   if {[package vcompare [package present tls] 1.7] > 0} {
      ::http::register https 443 [list ::tls::socket -autoservername 1]
   } else {
      ::http::register https 443 [list ::tls::socket -request 0 -require 1 -ssl2 0 -ssl3 0 -tls1 1]
   }
}

You are GEM of person CrazyCat, Script is working efficiently.
And all thanks to you CrazyCat.
But I need to know/change, Is it posible that TCL shows the NEWS at once on all channels it is on?
Please make it possible to you CrazyCat
Thanking already.
