1: Context bar and xowiki.
Posted by Richard Hamilton on 07/14/09 12:16 AM
I am just getting to grips with xowiki and have set up and openacs to serve an xowiki page as the overall site default index page.

That works fine such that a request for:

http://www.mydomain.com

...delivers the xowiki page designed to be the site homepage.

HOWEVER!

The context bar is, quite correctly:

mydomain.com : xowiki : home

I would like the context bar to be:

home :

...effectively trimming off the upper nodes when pages of the xowiki instance are being displayed.

I am comfortable with hacking the code to achieve this, but before I do I wanted to check if there is a parameter or configuration setting that will do this that I have overlooked?

If not I may hack it to chop the top two layers for all but admin users for example.

Thanks
Richard

Hi Richard,

to achieve your goal I'm using a small index.vuh script by Gustaf, placed into the top www folder. Here is the script: 

::xowiki::Package initialize -ad_doc {

  @author Gustaf Neumann (gustaf.neumann@wu-wien.ac.at)
  @creation-date July, 2006
  @cvs-id $Id: index.vuh,v 1.1.1.1 2008/11/10 09:06:52 alter Exp $
  } -parameter {
    {-m view}
    {-folder_id:integer 0}
  } -url /xowiki[ns_conn url]

  ::$package_id reply_to_user [::$package_id invoke -method $m]
  ad_script_abort

Fantastic, thank you Claudio. I'll try that.

It looks like a magic incantation! 😊

Looks as is if I need to bone up on ::xowiki::Package!

Claudio,

I put that index.vuh in the server root for the openacs instance and received the following error:

unknown argument '-' for method 'initialize': valid arguments -ad_doc {-parameter {}} {-package_id 0} {-url {}} {-user_id -1} {-actual_query { }} -original_url_and_query {-init_url true} -form_parameter
while executing
"::xotcl::interpretNonpositionalArgs $args"
(procedure "initialize" line 2)
::xowiki::Package ::xo::PackageMgr->initialize
invoked from within

Any idea what I have done wrong?

Regards
Richard

I suspect that during the copying and pasting of the script some weird character has been added.

I suggest that you drop any extra character from the command or write it by hand and retry.

Claudio,

I don't think that is it because I didn't do it that way. I noticed the similarity between the file you posted and the index.vuh from the xowiki/www directory, so I copied that file and then modified it by stripping out the additional lines and very carefully adding the one additional magic incantation.

The method 'initialize' receives an unexpected '-' argument and so something must be wrong in your script.

I would try writing the full ::xowiki::Package command without extra spaces on a single line.

Claudio,

Fantastic, thanks for your clearheaded guidance. The error unsurprisingly was in the only bit that I hand-typed. I had accidentally inserted a space between the '-' and 'url'.

Silly boy!

That has very nicely removed the xowiki package node from the breadcrumb trail. However it still leaves the main root node as follows:

Main : Home

In this case Home is the current page, and Main is a link to the currently displayed page (i.e. Home). This is clearly redundant.

Is it possible to change the -url declaration to in order to skip both superior levels, and if so can that be done only for non-logged in visitors?

Richard.

Can anyone please explain how the -url declaration in this index.vuh tells the request processor to pretend that one of the site nodes doesn't exist?

Also, I have been searching for documentation that explains '::xowiki::Package initialize' but I cannot find anything appropriate. Any pointers gratefully received.

Richard

"initialize" is a method of the xo* package manager, that initializes a package for a http request (query context).

If you google for "instproc initialize" you find the generic https://openacs.org/api-doc/proc-view?proc=%3A%3Axo%3A%3APackageMgr+instproc+initialize
There is as well some info in the xowiki tutorial: http://alice.wu-wien.ac.at:8000/s5-xowiki-tutorial/slides

Thank you Gustav. I am starting to work through your xotcl docs and these links will be very helpful.

I am hoping to get to grips with oo programming from scratch using xotcl in advance of re-writing an internal message package I wrote for an earlier version of OpenACS.

It is the kind of application that would lend itself to an oo approach.

12: XoTCL Modified Links when called from /index.vuh (response to 1)
Posted by Frank Bergmann on 01/22/13 05:24 PM
Hi,

Thanks for the solution with the index.vuh. I'd also like to setup a plain Web site that only consists of an XoWiki in the root directory.

However, I'd like all XoWiki pages to appear in the root ("/") folder. They are found there, but links included in these pages point to /xowiki/page.

So: is there an elegant solution to keep these links in the main directory (eliminate the /xowiki/ from the links)?

It should be relatively easy to modify ::xowiki::Link render or ::xowiki::Package make_link, but that would be quite ugly.

Cheers,
Frank
