[Gestalt-users] Interaction between = operator and paramters handling

[Florent G. <dar...@ya...>]

  Hi Colin,

  I just found a strange behaviour in Gexslt.  It seems to
be related to the parameter handling.  Here is the test
case.  Note that using the string 'deep-equal' directly
instead of using a parameter make the test to succeed.  As
well as using a variable instead of a parameter.  So the
last element in the result is:

    <expect select="$expect deep-equal $result"/>

however I think it would have to be:

    <expect select="deep-equal($expect, $result)"/>

(drkm)[75] ~/xslt/tests$ cat operator-equal.xml
<test:suite
    xmlns:test="http://www.fgeorges.org/xslt/unit-test">

  <test:tests id="hello-world-all">
    <test:title>hello-world()</test:title>
    <test:test>
      <test:title>hello-world(), arity 0</test:title>
      <test:expect test="$test:result eq 'Hello, world!'"/>
    </test:test>
    <test:test>
      <test:title>hello-world(), arity 1</test:title>
      <test:expect select="'Hello, Jeni!'" pred="eq"/>
    </test:test>
  </test:tests>

  <test:tests id="false">
    <test:title>False negative</test:title>
    <test:context select="$elem"/>
    <test:test>
      <test:expect as="element()+">
        <elem2 id="id"/>
      </test:expect>
    </test:test>
  </test:tests>

</test:suite>

(drkm)[76] ~/xslt/tests$ cat operator-equal.xsl
<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:test="http://www.fgeorges.org/xslt/unit-test"
    version="2.0">

  <xsl:output indent="yes"/>

  <xsl:param name="expect.pred.default" select="'deep-equal'"/>

  <xsl:template match="/">
    <root>
      <xsl:apply-templates/>
    </root>
  </xsl:template>

  <xsl:template match="node()">
    <xsl:apply-templates/>
  </xsl:template>

  <xsl:template match="test:expect">
    <xsl:variable name="pred-operators" select="'eq', 'is'"/>
    <xsl:variable name="pred"           select="
        if ( empty(@pred) ) then
          $expect.pred.default
        else
          @pred"/>
    <xsl:variable name="pred-call"      select="
        if ( $pred = $pred-operators ) then
          concat('$expect ', $pred, ' $result')
        else
          concat($pred, '($expect, $result)')"/>
    <expect select="{ $pred-call }"/>
  </xsl:template>

</xsl:stylesheet>

(drkm)[77] ~/xslt/tests$ gexslt operator-equal.xsl operator-equal.xml
<?xml version="1.0" encoding="UTF-8"?>
<root xmlns:test="http://www.fgeorges.org/xslt/unit-test">
   <expect select="deep-equal($expect, $result)"/>
   <expect select="$expect eq $result"/>
   <expect select="$expect deep-equal $result"/>
</root>

  Unfortunately, I wasn't able to reduce the test case
furthemore.  I hope it will help.

  Regards,
