Re^2: Using sprintf in regular expreession.

> Perhaps a bit more long winded

IMHO, you are overcomplicating it. sprintf can take a list of values, no need for a map.

It can even rearrange the order, tho I prefer the slice here.

  DB<23> $date = "3-15-1932"

#### split and slice

  DB<24> printf "% 4d-%02d-%02d", (split /-/, $date)[2,0,1]
 1932-03-15

#### match list

  DB<25> printf "% 4d-%02d-%02d", ($date =~ /(\d+)-(\d+)-(\d+)/ )[2,0,
+1]
 1932-03-15

#### reorder printf with 3$

  DB<26> printf "%3\$ 4d-%02d-%02d", split /-/, $date
 1932-03-15

#### classic

  DB<27> printf "% 4d-%02d-%02d",$3,$1,$2 if $date =~ /(\d+)-(\d+)-(\d
++)/
 1932-03-15
