Chained mutators can
  • Save typing
  • Create symmetry
  • Result in clearer code.
Here's a snippet from my own code. This probes a real-time audio application with a five channel OpenGL oscilloscope:
my $s= Scope->new('probe' => $netlist) ->anatrace('in', 'System input', 'active', 1) ->anatrace('out_1', 'Lpf bank1', 'active', 1) ->anatrace('out_2', 'Lpf bank2', 'active', 1024) ->anatrace('out', 'System output', 'active', 1) ->anatrace('bank2', 'Switch pos', 'active', 1) ->generate();
Want to see another channel? Call anatrace again.

I don't think that features with potential downsides should be 'considered harmful'.

It is possible to create a 'little language' out of chained method calls. I avoid creating little languages because I have seen a few of them grow into voracious blood-sucking monsters. I can enjoy chaining method calls without fear of triggering a science-related memetic disorder.

It should work perfectly the first time! - toma

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.
