regex - replacing with a numbered value -

this question has answer here:

suppose have string

$t = "some {great} vacation {we} had {year}"

and want replace placeholders numbered value:

"some {0} vacation {1} had {2}"

i'd have expected single replacement it:

$i = 0; $t -replace "{.*?}", "{$([string] ++$i)}"

but is:

"some {1} vacation {1} had {1}"

as if string evaluated once. in perl regex there's way specify function replacement value... how done in psh?

try this:

$i = 0 ; [regex]::matches($t,"{.*?}") | %{ ++$i ; $t = $t.replace($_.value,"{$i}") } ; $t

i think problem regex engine never gets new value of $i each match finds, every time increments it, $i 0.
