Re^2: how to split input data ?

does the look-behind count as mucking around? ;) (as opposed to having to shift off the first blank element)

perl -le 'print join ":", split /(?<=\d\d)(\d\d)/, "123456789"'
[download]

oh, i guess that doesn't work for '123' ... back to a little more mucking:

perl -le 'print join ":", grep {length} split /(\d\d)/, "123456789"'

`print +(join ' ', grep {/\d/} split /(..)/), "\n";` [download] was what I had in mind, although the autoflush trick (`--$\|`, see $\| pre and post increment and deincrement behavior) is kinda cute too ;). Update: added link DWIM is Perl's answer to Gödel	[reply] [d/l] [select]
