Re: [xwiki-users] Printing pages as displayed - xwiki-users@xwiki.org

These are excellent instructions. Thanks. I will give it a try next week and will report
back.

If anyone else has any input about the other issues, I'd be most grateful.

Kind regards,

Mahomed

I am always a bit uncertain which way is the best, too. However if you want to close your
content from anonymous users,
then you must go to the file system to make modifications to the style in any case.

Maybe the following works for you:

  http://platform.xwiki.org/xwiki/bin/view/DevGuide/Skins

I see this recommends copying over all files from the base skin - I guess that is
necessary in some cases, especially when all the LESS to CSS compilation takes place.

But if you only want to adapt e.g. the print.css, you can:
  - create directory /usr/lib/xwiki/skins/myskin
  - add a /usr/lib/xwiki/skins/myskin/skin.properties with 'parent=flamingo'
  - copy and adapt the  print.css from the "flamingo" dir into
"myskin"
  - test the new skin via e.g.
http://localhost:8080/xwiki/bin/view/Main/WebHome?skin=myskin
  - if this works, edit the "XWiki.DefaultSkin" to use "myskin" as
base skin instead of "flamingo"

That way you avoid patching the original skin from the distribution and minimize duplicate
file contents.

  Hi Clemens

 Thanks for the response.

the "black checkboxes" preventing any anonymous access, independent of view
rights.

 Unfortunately this is exactly what I have. It's important that even if users have
access to our LAN, only authenticated users can view the documents.

 Interestingly, if I use the default skin style.css then it works fine. In the meantime, I
have cheated and replaced style.css in /usr/lib/xwiki/skins/flamingo

 I am assuming I need to create my own skin folder and not use the skin app (though to be
completely honest, I am a bit confused which is the recommended way).

 Kind regards,

 Mahomed

 Hi Mahomed,

  I just know an answer about the last one ... I hope the rest will be answered by
others.

 If you want your skin customizations visible on the login page, too, then you need to
make sure the anonymous user can view the page with the modifications.

 Giving the XWikiAllGroup view permisisons is not enough, but you are in the right place;
if you look at the top of of the list showing all groups and their permission, you should
find a button to switch from groups to users - there you can give the "anonymous
user" view rights, too.

 This should work, unless you have secured the wiki in the adminstration with the
"black checkboxes" preventing any anonymous access, independent of view
rights.
 If you have done the latter, then the wiki content is fully protected, including skin
customizations, and unfortunately you cannot have both a wiki completely closed to
anonymous visitors and still have them view that single attachment on the login page;
 you would have to patch things by editing the webapp on the file system directly.

 Cheers
 Clemens

  That’s cool. Thanks Vincent ☺

 I finally got some time (and was forced to) look at implementing changes to the print
formatting. I had some mixed results. I’ll document what I’ve done below and the bits I am
having some trouble with and hopefully someone can provide me with further tips.

 1.       I managed to format the PDF Export output by attaching a pdf.css file to my
custom skin application (as per
http://extensions.xwiki.org/xwiki/bin/view/Extension/Skin+Application). This has mostly
worked for straightforward items like headers and font. But I am having trouble with some
of my tables and it would help if I could reduce the margins of the page.
 QUESTION: Is there a simple way to modify the margins (I need narrower margins)

 2.       I tried to format the printed output but found that attaching a print.css to my
skin application did very little/nothing to format the output. I tested by creating an
article in the Sandbox, Clicking “More Actions” > “Print Preview” > Press Ctrl+P.
This was testing in Chrome and Firefox with the same effect/results.

 3.       I then found that there were several @Media=”Print” sections in the Style.css
file. So I downloaded this, removed the @Media sections and re-attached my new style.css
to my skin application. This now allowed my formatting in the attached print.css to take
effect. So this now works and looks as I would expect. But I don’t really like the idea of
having my own style.css as it’ll make it more difficult to take advantage of any new
formatting changes that may be added later (unless I’ve missed the point here)

 4.       I have locked down the xwiki so that only registered and logged in users can
view any of the documents. Unfortunately this now means that style.css is not accessible
on the login page. I have modified the access rights on the skin application and given
view permissions to XWikiAllGroup but I suspect I need to somehow give access to guests
but I can’t see how to do that.

 Sorry for the long email and I hope I’ve explained clearly. Any help greatly appreciated
(as always).

 Kind regards,

 Mahomed
