S soulz
soulz S	Hi hos it goin, I am tempting to make a search command for a help script in one of my channels. The search is keyword based, and searches a text file for results. However the text file recently got a bit bigger for offering support. and I now need help to figure out how to make the search display more then one result seeing as some keywords people may use may return with more then one result. What I was using before.. the $read command... on :text:!trigger :#: { //echo -a $read(textfile.txt, w, $2) if ($readn == 0) { /notice $nick No help topics match the keyword you are searching with. \| goto done } /notice $nick $read(textfile.txt, $readn) :done { } } no longer works for the desired results.. If someone could help me out with this point me in the right direction that would be helpful thanks

Secondly, you could use a loop, since you want more than 1 result. A fast thing would be to use the file handling functions (or maybe /filter, but I'll stay with the former ones). Edit: I've left $1 instead of $2.. fixed now. It was from my tests before I posted the code here (meaning, it works) Code: on :text:!trigger :#:{ if ($fopen(help)) .fclose help .fopen help textfile.txt [color:brown]:seek_until_eof .fseek -w help * $+ $2* if (!$fopen(help).eof) { notice $nick $fread(help) var %found = 1 goto seek_until_eof }[/color] elseif (!%found) notice $nick No help topics match the keyword you are searching with. .fclose help } The main point here is the loop, I just thought that doing it with /f* and $f* functions would be better than a lot of $read's. I didn't use /while because this was a "do...until" case. /while would check the end of file (eof) before the script would search for the trigger, and I needed it to search first and then check eof.

Iori I	I think it would be better to use /filter and /play rather than $read or $fread. /filter being faster, and play able to send multi messages/notices without flooding. Code: on :text:!trigger :#:{ var %a = $ticks $+ .txt filter -ff textfile.txt %a $+(,$2-,) if $filtered { .play -n $nick %a 1000 \| .remove %a } else notice $nick No help topics matching $+(",$2-,") }

You can still use /while, in the same way we use /while in sockread loops: Code: .fopen blah file.txt .fseek -w blah bleh while !$feof { dostuffwith $fread(blah) .fseek -w blah bleh } .fclose blah

By the way, I prefer not using /while in /sockread loops for the same reason (unless it becomes considerably faster when speed is much important). Last edited by cold; 28/10/03 04:56 PM.

Here's a non-flooding /f* version:

Code:

on *:text:!trigger *:#:{
  $iif($timer(.help), .timer.help. $+ $nick 1 $timer(.help).secs) _help $nick $1-
}
alias _help {
  ; $1 = nick, $2 = !trigger, $3 = match string
  if ($fopen(help)) .fclose help
  .fopen help textfile.txt
  :seek_until_eof
  .fseek -w help * $+ $3*
  var %found = 0
  if (!$fopen(help).eof) {
    inc %found
    .timer.help. $+ %found 1 %found notice $1 $fread(help)
    .timer.help 1 %found halt
    goto seek_until_eof
  }
  elseif (!%found) notice $nick No help topics match the keyword you are searching with.
  .fclose help
}

However, looking at how big this became, I must agree that /filter+/play offers a better method. Just don't forget to take a look at file handling functions..
