Hi,
After discussing with Thomas we've reached the conclusion that we
should change the way the HTML macro handle its content when wiki=true.
For ex take the following input:
{{velocity}}
...
{{html wiki="true"}}
<form>
$xwiki.includeForm("XWiki.MyClassSheet")
<br />
<p>
<input type="submit" name="submit" value="Create this new
Workpackage" />
</p>
</form>
{{/html}}
...
{{/velocity}}
And assume that MyClassSheet has some $doc.display() velocity code
which thus generate {{html}} macros.
Current Result
============
Right now here's what happens:
1) velocity macro is executed and $xwiki.includeForm executes
2) MyClassSheet generate {{html}} macro content thus yielding:
{{html wiki="true"}}
<form>
{{html}}...<someTag>...</someTag>{{/html}}
</form>
{{/html}}
3) After velocity has finished executing the velocity macro calls the
wiki parser on the result and thus the top level HTML macro executes
4) since wiki=true the content is given to a SAX parser and each XML
tag content is given to the wiki parser. Thus "{{html}}...", "..." and
"{{/html}}" will be parser by the wiki parser separately (because
<someTag> is valid XML), thus generating non expected content as a
result.
Proposed change
==============
Modify the HTML behavior so that the wiki parser executes first
(instead of the SAX parser) and render the result using a special
renderer that prints the special symbols and text as is.
When run on our example this would give (same steps 1) and 2)):
3) wiki parser executes and generate XDOM. Render it using the special
renderer
Note that this means that if in HTML your write content that has a
meaning in some wiki syntax you'll need to escape it. For example if
you have:
{{html wiki=true}}
<!--hello-->
{{/html}}
you'll get some strikethrough. So you'll need to write instead:
{{html wiki=true}}
<!~-~-hello~-~->
{{/html}}
WDYT?
Here's my +1
Thanks
-Vincent
