( #3333=superdoc: print w/replies, xml ) Need Help??
I was trying to figure out what hashes were in some code. It was a new code base that I needed to become familiar with (no docs, naturally).

This command line does a pretty good job of making a hierarchical listing from the code. What would you do better?

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

It only picks up -> derefs but everyone here (ed:at the office) seems to code that way, so it's a win for me.

ed2: I didn't give an example of the output, which ends up looking something like this:

... $people->{login}->{chair}->{color}=something $people->{login}->{chair}->{height}->(blah) $people->{login}->{chair}->{wheels} =~ etc $people->{login}->{desk}->{paperclips} $people->{login}->{desk}->{stapler} ...

Use:  <p> text here (a paragraph) </p>

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.
