I know a little bit about XS - just enough to be dangerous (ie "a little knowledge is a dangerous thing"). I couldn't help at all with SWIG (though "swigging grog" is what I've been doing for most of the evening :-)

One advantage of XS over SWIG seems to be that help and advice is much more readily available for XS than it is for SWIG - simply because more people are using XS.

Another advantage of taking the XS route, imho, is that Inline::C (which should perhaps have instead been called "Inline::XS") is available - which makes the learning curve so much gentler.

Cheers,
Rob

• 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.
