I guess we could improve the link and image syntax to support paths
starting with / and then consider them as paths relative to the
context root. However it wouldn't work for relative paths such as
../../some/path.
Right now we could easily add a XWiki API to get an absolute URL from
a relative one.
Note that you can still use the old syntax using the {{velocity}}
{{html}}a href=..{{/html}}{{/velocity}} but that's not very
nice and it would be nice if it could be written using the new syntax
but was made to avoid using HTML... :)
Would recognizing references starting with / a good solution for
you? What do others think?
I guess checking for / at the beginning would work, or maybe some
way of
flagging it as a relative path would be even better (maybe something
like
[[image:img.png||relative=true]]). Not sure how feasible this is,
or if it
would make sense to do so...
See the vote I've sent on this:
http://tinyurl.com/c737ve
This won't be in 1.8 final but will be in 1.9M1.
This is not correct. The html macro must contain HTML. This is not the
case in your example. You need this:
{{velocity}}
* this works - [[image:
http://localhost:8080/$xwiki.getSkinFile('icons/black-file.pnghttp://localhost:8080/$xwiki.getSkinFile%28%27icons/black-file.png
')
]]
* this doesn't work - {{html}}img src=$xwiki.getSkinFile('icons/
black-file.png')/{{/html}}
{{/velocity}}
It seems that the HTML Macro's final filter parses this last test
case as 1
BulletedListBlock and 1 XMLBlock, but I'm not sure if this the
expected
behavior. If this is the expected behavior, the more need to get
the
[[image:]] tag working...
Thanks again for the great job!
Hm... kind of makes sense but, what does the wiki=true flag do,
then...?
It means that HTML element content can contain wiki syntax as in:
elementtext with wiki syntax here/element
It's also a bit problematic for me since I have the following (posting
everything, since this might be useful for others as well):
--
{{velocity}}#set($serverClassFullName = Server.ServerClass){{/
velocity}}
{{velocity}}#set($serverDocumentSQL = select distinct doc from
Document as
doc, doc.object(${serverClassFullName}) as obj where obj.name
'${serverClassFullName}Template'){{/velocity}}
{{velocity}}#set($serverDocuments =
$xwiki.queryManager.xwql($serverDocumentSQL).execute()){{/velocity}}
There are currently {{velocity}}**${serverDocuments.size()}**{{/
velocity}}
document(s) containing Server objects.
{{velocity}}
Why do you repeat the velocity macro several times? You can wrap all
the macros into one single velocity macro.
{{html}}
This one can also be in the top level velocity macro.
table id=serverList class=grid sortable filterable doOddEven
tr class=sortHeader
th class=selectFilterSpace/th
thClass/th
thServer/th
th class=unsortable noFilterLink/th
/tr
Note that in the future we've planned to add filterable/sortable
tables in the new table syntax directly.
#foreach($serverDocument in $serverDocuments)
#set($serverObjectSQL = select obj.hostname, obj.prettyName,
obj.urlRoot, obj.hostName from Document as doc,
doc.object(${serverClassFullName}) as obj where doc.id =
${serverDocument.id})
#set($serverObjects =
$xwiki.queryManager.xwql($serverObjectSQL).execute())
tr
td${serverDocument.space}/td
td${serverDocument.name}/td
td
#foreach($serverObject in $serverObjects)
#set($server = $listtool.get($serverObject, 0))
#set($serverPrettyName = $listtool.get($serverObject , 1))
#set($serverURLRoot = $listtool.get($serverObject, 2))
#set($serverHostName = $listtool.get($serverObject , 3))
* ${serverPrettyName} - a href=${serverURLRoot}img
src=$xwiki.getSkinFile('icons/black-file.png') alt=Root URL
title=Root
URL //a a href=${serverHostName}img
src=$xwiki.getSkinFile('icons/black-rss-mini.png') alt=Host Name
title=Host Name //a
#end
/td
td[[${serverDocument.name}${serverDocument}]]/td
/tr
#end
/table
{{/html}}
{{/velocity}}
This looks good.

This will list out all the properties of Server.ServerClass for all
documents that contain a Server.ServerClass object in it. I got
this to
work by replacing the XWiki list syntax with:
td
ul
#foreach($serverObject in $serverObjects)
#set($server = $listtool.get($serverObject, 0))
#set($serverPrettyName = $listtool.get($serverObject , 1))
#set($serverURLRoot = $listtool.get($serverObject, 2))
[xwiki-users] Images in links
Hi xwiki-users,
In XWiki Syntax 1.0, I was able to do something like this:
a href=${documentURLRoot}img
src=$xwiki.getSkinFile('icons/black-file.png') alt=Root URL title=Root
URL //a
This would render an icon from the current skin as a link. I understand
that in XWiki Syntax 2.0, there's a new form of this available:
[[image:space.w...@picture.png${documentURLRoot}]]
This works if the image exists in your document as an attachment, but
doesn't work when the image link is relative to your web context:
[[image:$xwiki.getSkinFile('icons/black-file.png')${documentURLRoot}]]
This renders as the following:
a href=http://www.google.com/;
img alt=/xwiki/skins/albatross/icons/black%2Dfile.png
class=wikimodel-freestanding
src=/xwiki/bin/download/XWiki/WebHome/%2Fxwiki%2Fskins%2Falbatross%2Ficons%2Fblack%252Dfile.png/
/a
which is not what I expected... One workaround is to put an explicit
http://server-name:port/; before the $xwiki.getSkin() call, but that ties
the wiki to the server's address/port.
One other interesting thing I found out was that:
{{velocity}}
{{html wiki=true}}
* this works - [[image:
http://localhost:8080/$xwiki.getSkinFile('icons/black-file.png')]]
* this doesn't work - img
src=$xwiki.getSkinFile('icons/black-file.png')
{{/html}}
{{/velocity}}

BulletedListBlock and 1 XMLBlock, but I'm not sure if this the expected
behavior. If this is the expected behavior, the more need to get the

Since $documentURLRoot is velocity syntax you'd need to wrap it in
{{velocity}} macro but indeed it'll still not work for the moment
since the link syntax supports either absolute URL or document
references but not relative paths.
So right now you'd need to make documentURLRoot absolute. There are
some xwiki api to do so.
This works if the image exists in your document as an attachment, but
doesn't work when the image link is relative to your web context:
[[image:$xwiki.getSkinFile('icons/black-file.png')$
{documentURLRoot}]]
Same here, the image syntax doesn't support relative paths.

BTW this is the default I think so no need to specify wiki=true AFAIR.
