$FILTOK

By SyntaxIRC on Mar 07, 2008

Usage: $filttok(TOKEN,RANGE,C)
Example: $filttok(a.b.c.d.e,b-c,46) will return a.d.e

As you can see, it works for both letters and numbers and will filter out the range.

alias filtok {
  var %x = 1, %ftok = $1
  while %x <= $numtok($1,$3) {
    var %ftok = $iif($regex($gettok($1,%x,$3),/[ $+ $2 $+ ]/i),$remtok(%ftok,$gettok($1,%x,$3),1,$3),%ftok)
    inc %x
  }
  return %ftok
}

Hmmm yeah. Maybe it would be good so the user could specify letters to filter via a comma, and recognise the last parameter used as the token.

Because if you use d-e for example that's like a range. I mean, what if you wanted to filter "a" and "z" together? You'd filter and get rid of the entire string!

True.

However I used

//echo -ag $filtok(a.d.r.e.t.e.d.s,d-e,46)

and got left with only "a" when it should have been "a.r.t.s" yes?

Kind of, but it deletes any occurence of the letter.

This looks alot like $deltok

From /help

$deltok(text,N-N2,C)

Deletes the Nth token from text.

$deltok(a.b.c.d,3,46)        returns a.b.d
$deltok(a.b.c.d,2-3,46)        returns a.d

You can specify a negative value for N.
