( #3333=superdoc: print w/replies, xml ) Need Help??

This seems to work.

knoppix@Microknoppix:~$ perl -E ' > @l = qw{ a bb c d e f g h }; > say sub { join q{ }, @_ }->( > grep defined, map shift @l, 1 .. 3 > ) while @l;' a bb c d e f g h knoppix@Microknoppix:~$

I also piped the output through hexdump to check that there were no trailing spaces (which you do get without the grep).

Update: Using List::Util::min() to remove the need for the grep.

knoppix@Microknoppix:~$ perl -MList::Util=min -E ' > @l = qw{ a bb c d e f g h }; > say sub { join q{ }, @_ }->( > map shift @l, 1 .. min( 3, scalar @l ) > ) while @l;' a bb c d e f g h knoppix@Microknoppix:~$

Cheers,

JohnGG

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
