indeed, you can of course pass extra information to the alias, here's an interesting example:
alias filteralias {
if ($prop == recursive($1-)) {
; stuff
}
else {
filter -fk a.txt filteralias($1).recursive
}
}
it lends some insight into how
/filter sets up the alias: by appending
($1-) to the given parameter, prefixing it with
$ and evaluating the result in an environment where
$1 is each line in turn. as such, you can pass extra parameters (if this
$prop approach is a bit ugly) and whatever else to identify the calling routine.
that said, a
$calias would be lovely!
