I hate source filters, it reeks preprocessing. Preprocessors usually don't know much of the language they generates and that leads to defensive programing:

#define ADD(a,b) a+b /* I should have writen (a+b) */ ADD(1,2)*3 /* gives 7 instead of 9 */

If you are not convinced of preprocessor horrors, looks at the source of perl5. Yes, the C preprocessor gets us around the limitation of the language and it is one of the reason why C is still well alive. See the GNU macros that allows the same include files to be both K&R and ANSI-C. It works but it is not pretty. Parrot is indded written in C.

But, I like TheDamian source filters because it gets me the perl6 flavor. So, I can get over my dislike of source filters. But they are still a hack.

But really with perl6, I hope we will be able to deal with any input without pipelining processors.

But there is more indeed to source filters than filters that translate a language in a lesser language. Your examples show that source filters can be useful _and_ lovable.

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.
