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

Addressing the golfing request,

# 123 rgrep -e'->' * | perl -ne '/(\S{3,80}->\S{5,80})/;print $1,"\n"' | pe +rl -pe's/^\(//' | perl -pe 's/^\+\+|^\-\-//' | sort | uniq

is sufficiently equivalent to

# 68 perl -ne's/^(\(|[+-]{2})//g,say for/(\S{3,80}->\S{5,80})/' *|sort -u

And since you already assume that you can't have two dereferencing expressions on the same line,

# 67 perl -ne's/^(\(|[+-]{2})//g,say for/\S{3,80}->\S{5,80}/g' *|sort -u

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.
