( [id://3333]=superdoc: print w/replies, xml ) Need Help??

In larger scripts, I simultaneously handle that and the clarity issue by writing code like this
001 use IO::Handle; 002 STDOUT->autoflush;

I got kinda turned off of IO->Handle when I read this comment in the pod

use IO::Handle; # thousands of lines just for autoflush :-(

When I read the authors name, it strengthened the feeling.

Update: To clarify, the author to which I referred was the author of the comment I quoted above--from the pod of perlipc not IO->Handle--Tom Christiansen, who comments are to be valued.

I have absolutely nothing against Graham Barr (the author of IO::Handle), nor even much against that module.

My only reservation was of the practice of using IO->Handle only for the purposes of turning on autoflush.

If $|=1; $|=0; is deemed to cryptic, you could use something like:

sub autoflush (*$) { # Set the state of autoflush for # the handle supplied as $_[0] # to the boolean state supplied as $_[1] select( do{ my $old = select( $_[0] ); $| = $_[1]; $old; } ) } ... autoflush( STDOUT, 1 ); # autoflush on ... autoflush( STDOUT, 0 ); # autoflush off

If I understand your problem, I can solve it! Of course, the same can be said for you.

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 How to display code and escape characters are good places to start.
