[SWAT]

This is my RSSnews file. It works great (with private notices and all). But I noticed that the scripts doesn't use the 'database files' anymore. It didn't create new ones and it didn't update them. Can anyone help me fix this? Below is the my 'edited' script.

Code: Select all

array unset feed

set feed(3DGamers) {
  URL=http://www.3dgamers.com:80/feeds/netscape/3dgamers.rss   /* The location of the news, in format http://domain.com:port/file.xml (port value is optional). */
  DATABASE=scripts/dbase/rssnews/.3dgamers                     /* The file where the news are saved. */
  CHANNELS=#CeTa		                               /* On which channels is the feed activated? Set to ALL for all channels. */
  POSTNEWS=0                                                   /* Post news if there are new ones? */
  POSTLIMIT=3                                                  /* max. posted news */
  PUBLIMIT=3                                                   /* How many news are posted on pub triggers? */
  MSGLIMIT=3                                                  /* How many news are posted on msg triggers? */
  /* Thats the design used for automated output. */
  POSTLAYOUT=\00300,14\[\00309\002!\002\00300\] \00300www.\002\003093D\00300gamers\002.com \[\00309\002!\002\00300\] <news> \[\00309\002!\002\00300\] <link> \[\00309\002!\002\00300\]\003
  /* And this one is for use on trigger events. */
  TRIGLAYOUT=\00300,14\[\00309\002!\002\00300\] \00300www.\002\003093D\00300gamers\002.com \[\00309\002!\002\00300\] <news> \[\00309\002!\002\00300\] <link> \[\00309\002!\002\00300\]\003

[demond]

there is no need of database files to compare if something in the feed has changed or not - see my rss script for example

[SWAT]

I'll have a look at your script later (I can't look at any code anymore, and the other scripts is currently working). The database files are VERY handy. If you set the script for updating the text files every X minutes (for example 60 or 30) and then post the content from the textfile to the channel, the data-traffic would decrease. Because if 10 users would use the rssfeed-command in 10 minutes, the website would get 10 hits (and you'd have to wait longer, because every time the website needs to be contacted.)

Example:
Without DB files: 10 users in 10 minutes = 100kb traffic and waiting time is 10 seconds.
With DB files: 10 users in 10 minutes = 10 kb traffic and waiting time is 2 seconds.

[demond]

my script is fundamentally different from perplexa's, it doesn't fetch feeds on user demand, it fetches feeds periodically and compares feeds contents in memory, announcing only updated headlines as necessary

naturally, it has the whole feeds contents available at all times (in memory, not in file), and it sends that content out on demand

[rix]

hey, you got this nice script, but there's one thing bothering me - it posts feed to channel randomly, but I want it to post only when the trigger is pulled.

already tryed demond's script but that didn't work for me
