Hi Florent,

Not entirely sure, but I think options should be specified from outside, or declared with some default. It should be possible to add a select="false()" to such options.

When test="$opt" is the kind of syntax I would have used in XSLT 1.0, but you might need to be more explicit with Calabash. I occasionally use expressions like: string-length($opt) > 0, or: (lower-case($opt) = ('1', 'y', 'yes', 'true'))..

Kind regards,

Onderwerp: Passing options from the command-line


  Given the following pipeline:

    <p:pipeline xmlns:p="http://www.w3.org/ns/xproc" version="1.0">

       <p:option name="opt"/>

          <p:when test="$opt">
                <p:input port="source">
                <p:input port="source">


I'd assume to get the following results:

  1/ if I evaluate it without passing any option explicitely,
     then the output would be <otherwise/>

  2/ if I evaluate it passing $opt as an empty string, then the
     output would be <otherwise/>

  3/ if I evaluate it passing any non-zero-length string for
     $opt, then the output would be <when/>

  But that's not what I observe with Calabash 0.9.33.  For 1/ it
complains $opt has not been declared, and for 3/ it still gives
me <otherwise/>.

  Did I make wrong assertions?
