Oh I agree completely. I actually originally put a line like "and in perl you have even better options with the modifiers that are available" but it didnt quite fit so I took it out. Perl modifiers and control flow keywords are an excellent way to minimize excessive indentation and containment problems.

Nevertheless I do think that "the smaller part of a conditional should go first" is a correct rule of thumb. If you have a 4 line block and a 40 block then the 4 liner should go first. This means the maintainer can see all of one and part of the other on one page, whereas with the long block first the maintainer can only see part of one block, and may not even notice the presence of the smaller one.

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.
