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

One way you can indent HEREDOCs is to substitute the leading spaces in a map.

$ perl -e ' $x = 1; if( $x ) { print map { s{^ }{}gm; $_ } <<" EOT"; Line 1 Line 2 \$x is $x Line 4 EOT }' Line 1 Line 2 $x is 1 Line 4 $

This really is not a serious suggestion. It is rather horrible, probably inefficient and it would be a nightmare to maintain in a script. It would easily break if code is moved around and logical depth (thus indentation) changes or if you use an editor that decides off its own bat to use tabs instead of spaces when auto-indenting.

I just post the code as a curio. Downvote if nauseated.

Cheers,

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.
