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

Something like the following might help get you started. Call it with the prompt and list of words. It'll return either undef or the word selected in scalar context. In list context it will also return the reply entered by the user. (To preserve the $REPLY functionality of the ksh builtin.) It preserves my ksh's interpretation of input which allows trailing characters after the number.

sub ksh_like_select { my $prompt = shift; my @words = @_; my $retval; my $reply; do { my $i = 1; print STDERR $i++, ")\t$_\n" for @words; print $prompt; $reply = <STDIN>; } while ($reply eq ''); if ($reply =~ /^(\d+)/ and $1 > 0 and $1 <= @words) { $retval = $words[$1-1]; } wantarray() ? ($retval,$reply) : $retval; }
Caution: Don't rename it "select" before using it. ;-)

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.
