This XQuery loads a GCC-XML file and reports the locations of all
global variables in the original C++ source. To run the query,
use the command line:
xmlpatterns reportGlobals.xq -param fileToOpen=globals.gccxml -output globals.html
&quot;fileToOpen=globals.gccxml&quot; binds the file name &quot;globals.gccxml&quot;
to the variable &quot;fileToOpen&quot; declared and used below.
:)
declare variable $fileToOpen as xs:anyURI external;
declare variable $inDoc as document-node() := doc($fileToOpen);
(:
This function determines whether the typeId is a complex type,
e.g. QString. We only check whether it's a class. To be strictly
correct, we should check whether the class has a non-synthesized
constructor. We accept both mutable and const types.
:)
declare function local:isComplexType($typeID as xs:string) as xs:boolean
{
exists($inDoc/GCC_XML/Class[@id = $typeID])
or
exists($inDoc/GCC_XML/Class[@id = $inDoc/GCC_XML/CvQualifiedType[@id = $typeID]/@type])
};
(:
This function determines whether the typeId is a primitive type.
:)
declare function local:isPrimitive($typeId as xs:string) as xs:boolean
{
exists($inDoc/GCC_XML/FundamentalType[@id = $typeId])
};
(:
This function constructs a line for the report. The line contains
a variable name, the source file, and the line number.
:)
declare function local:location($block as element()) as xs:string
{
concat($inDoc/GCC_XML/File[@id = $block/@file]/@name, &quot; at line &quot;, $block/@line)
};
(:
This function generates the report. Note that it is called once
in the &lt;body&gt; element of the &lt;html&gt; output.
It ignores const variables of simple types but reports all others.
:)
declare function local:report() as element()+
{
let $complexVariables as element(Variable)* := $inDoc/GCC_XML/Variable[local:isComplexType(@type)]
return if (exists($complexVariables))
then (&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml/&quot;&gt;Global variables with complex types:&lt;/p&gt;,
&lt;ol xmlns=&quot;http://www.w3.org/1999/xhtml/&quot;&gt;
{
(: For each Variable in $complexVariables... :)
$complexVariables/&lt;li&gt;&lt;span class=&quot;variableName&quot;&gt;{string(@name)}&lt;/span&gt; in {local:location(.)}&lt;/li&gt;
}
&lt;/ol&gt;)
else &lt;p xmlns=&quot;http://www.w3.org/1999/xhtml/&quot;&gt;No complex global variables found.&lt;/p&gt;
,
let $primitiveVariables as element(Variable)+ := $inDoc/GCC_XML/Variable[local:isPrimitive(@type)]
return if (exists($primitiveVariables))
then (&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml/&quot;&gt;Mutable global variables with primitives types:&lt;/p&gt;,
&lt;ol xmlns=&quot;http://www.w3.org/1999/xhtml/&quot;&gt;
{
(: For each Variable in $complexVariables... :)
$primitiveVariables/&lt;li&gt;&lt;span class=&quot;variableName&quot;&gt;{string(@name)}&lt;/span&gt; in {local:location(.)}&lt;/li&gt;
}
&lt;/ol&gt;)
else &lt;p xmlns=&quot;http://www.w3.org/1999/xhtml/&quot;&gt;No mutable primitive global variables found.&lt;/p&gt;
};
(:
This is where the &lt;html&gt; report is output. First
there is some style stuff, then the &lt;body&gt; element,
which contains the call to the \c{local:report()}
declared above.
:)
&lt;html xmlns=&quot;http://www.w3.org/1999/xhtml/&quot; xml:lang=&quot;en&quot; lang=&quot;en&quot;&gt;
&lt;head&gt;
&lt;title&gt;Global variables report for {$fileToOpen}&lt;/title&gt;
&lt;/head&gt;
&lt;style type=&quot;text/css&quot;&gt;
.details
{{
text-align: left;
font-size: 80%;

.variableName
{{

&lt;/style&gt;
&lt;body&gt;
&lt;p class=&quot;details&quot;&gt;Start report: {current-dateTime()}&lt;/p&gt;
{
local:report()
}
&lt;p class=&quot;details&quot;&gt;End report: {current-dateTime()}&lt;/p&gt;
