( #3333=superdoc: print w/replies, xml ) Need Help??
1. while (<>) { ... } or while (my $line = <>) { ... }? I use both, depending on whim and my assemement of readability. 2. -w or use warnings;? -w, but only because of muscle memory. 3. sub CONSTANT () { ... } or use constant CONSTANT => ...;? use constant CONSTANT => ...; 4. my ($foo, $bar) = @_; or my $foo = shift; my $bar = shift;? I always shift $self. Whether or not to shift the other args or use array assignment kind of depends. Whim again, I'm afraid. 5. for (@array) { ... } or foreach (@array) { ... }? foreach. My undergrad degree was in Math. 6. print 'foo'; or print('foo');? No parens unless needed for precedence. 7. 'simple string'; or "simple string"? Double quotes. 8. glob '*' or <*>? opendir(); readdir(); closedir(); 9. readline *FOO or <FOO>? <FOO> 10. for (keys %foo) { $_ and $foo{$_} } or while (my ($key, $value) = each %foo) { $key and $value }? Depends on whether or not %foo is tied to a DBM. I use the 'each' form on DBMs, having been burned once by pulling all keys into memory on a big DBM.

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.
