RSS News Help - (perpleXa's rssnews)

[Pougee]

I've been using this script for a little while. Works great for what i want it to do. The 5 fields <upfirstchar text>, <id>, <publisher>, <news>, <link>
are good. But is there a way to add customized fields?

Thanks
Pougee

Well this was a big learning curve, I haven't played in tcl and decide to have a crack for myself and got it working.

This is what i got

## FAQ:
##
## Q. What are these weird characters in the layout?
## A. You can use <upfirstchar text>, <id>, <publisher>, <news>, <link>,
##    as well as control codes, to change the design to something you'd like
##    Available colors and control codes are:
##     \002 bold
##     \003 [00-15] colors
##     \017 reset control codes
##     \026 reverse
##     \037 underline
##
## Q. How do I control this script?
## A. There isn't much to say, just type $news <feed> in a channel or /msg <bot> news <feed>
##    All the other stuff works automatically. ie. When you set your feed like "set feed(ESReality) { ... }"
##    you have to type $news ESReality or /msg <bot> news ESReality to receive news from that feed.
##
## Q. How do I setup my own feeds?
## A. Look at the examples below, you should find all neccessary information in the first one.
##
## Q. Where can I find more feeds?
## A. Try out http://www.feedroom.com and http://www.syndic8.com/
##
## Q. I've discovered a bug, what should I do?
## A. Write an email, use the contact field on my website or contact me on #perpleXa (QuakeNet)

hi

you can include the db-file on webpages


cya

[Cr4sh]

A question:

DATABASE=scripts/dbase/rssnews/.virus

in which format this file is?

you can include the db-file on webpages

I read the news from a php nuke site based...

[demond]

I wanted to modify it for to have an automatic news reader, then when i post on the site a news, the script report it on the channel...

use rssnews, it does exactly what you need

[Cr4sh]

Thx, i'll try it immediately!

edit: It works very good, thank you very much!!
Now, if it isn't a problem for you, i'll try to modify the output like this:

- title - url -
- title - url -

[demond]

of course it's not a problem for me, all my scripts are freeware, released under no license - that means you are free to use & modify them as you wish

[Cr4sh]

I'm sorry, but i'm very newbie in this language...

I don't know this:

Code: Select all

	set idx [expr {$num-1}]
		puthelp "notice $nick :......title($num): [lindex [lindex $news($chan) $idx] 0]"
		puthelp "notice $nick :description($num): [lindex [lindex $news($chan) $idx] 2]"
		puthelp "notice $nick :.......link($num): [lindex [lindex $news($chan) $idx] 1]"
		return 1

In the backend file i have 2 variables: <title> and <link>
Why the bot don't write the link on the channel?

[Cr4sh]

I've found the solution!!!

The right line to modify is this:

Code: Select all

puthelp "privmsg $chan :($idx) $title"

Now i can to modify it as i want!!

demond, thx again for ur script.
