Keep the faith, Brother!

Having been a Smalltalk user for at least 5 years now, one thing that helps in typical Smalltalk environments is their checking of method names when you define new methods. Every time you edit a method, it's recompiled; the compiler does a simple check to see if any of the method names you're using haven't been defined yet. If so, you get a warning. This has helped me detect a lot of typos in my code.

I'm thinking that a similar strategy could be used with Perl, by scanning programs like this:

  • For each 'use'd or 'require'd package, make a defined symbol list (easiest way to do this is probably just to use B::Xref).
  • Scan your program for method calls (or, more simply, for words, removing all the Perl pre-defined words).
  • Make a list of all the method calls (or words) in your program that don't match any of the subroutines defined in your included packages

This is a simple strategy, and it should be easy to implement. Tell me if it works!

I still prefer full testing, though. Have you read anything about Extreme Programming techniques? One of the XP tenets is to write tests FIRST.

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.
