Merge lp:~zorba-coders/zorba/new-xqdoc into lp:zorba

[William Candillon]

New and improved XQDoc.
Each module is completely decoupled from one to another and therefore more reusable. This will enable more people like 28msec to reuse this components and improve their maturity.
As an example, the HTML generation, the navigation generation, and the batch processing are completely decoupled.
Moreover, the schema and example resolution now is more modular for the Zorba and 28msec website.

I will propose the appropriate @project tag updates on non-core modules.
Core and non-core modules have a lot of issues related to their own documentation. I'm gonna propose fixes for these separately.

[Matthias Brantner (matthias-brantner)]

Does this change fix any of the xqDoc-related bugs that are still in the 2.7 milestone: https://launchpad.net/zorba/+milestone/2.7? Just want to make sure I understand the big picture.

[Sorin Marian Nasoi (sorin.marian.nasoi)]

after compiling zorba and running "make xqdoc" I get an error:
file {/home/spungi/work/zorba/repo/new-xqdoc/build/xqdoc/generator/xqdoc-xml.xq} not found or not readable.

the same error shows for "make doc".

1) @project tags for the following modules are wrong:
- modules/com/zorba-xquery/www/modules/node.xq
tag Zorba/XQuery Data Model/Node/Node
should be Zorba/XQuery Data Model/Node

-modules/com/zorba-xquery/www/modules/store/documents/dynamic.xq
tag Zorba/Data Store/Documents
should be Zorba/Data Store/Dynamic/Documents

-modules/com/zorba-xquery/www/modules/debugger/dbgp-message-handler.xq
tag debugger
should be Zorba/debugger

- modules/com/zorba-xquery/www/modules/xqdoc.xq
tag Zorba/XQDoc/XQDoc
should be Zorba/XQDoc/XQDoc generator or something similar

2) modules/functx/functx.xq has to be like his author wrote it:
please do not make any changes to the file, adapt the XQDoc generator instead to handle the missing @project tag.

3) if you want to "convince" people to add a @project tag for the module they write please add a test for checking the @project tag under test/rbkt/zorba/xqdoc

in file doc/zorba/xqdoc/CMakeLists.txt
please put back the code for generating the module dependency graph.

review: Disapprove

[William Candillon (wcandillon)]

Thanks for the review.

- I pushed a fix for the build.
- I double checked the @project tag, they all look correct. I change XQDoc to XQDoc Core to make it more explicit.
- Regarding Functx.xq, it was my understanding that this would require to update third-party modules manually. Also functx happens to be manually modified already (the namespace is different). I am not convinced about this @project tag solution, please let me know if you would like me to drop support for it.
- I can add a test for checking for the @project tag. Which test in particular? There is a module that doesn't appear in the documentation (the debugger one). Again it all comes down on the @project tag support. I would be happy to drop support for the @project tag. From my experience of building xquery documentation, I am not convinced at all about his usefulness.
- Regarding the dependency graph, could you please put it back yourself? I was not able to do it myself as it was highly coupled with the old codebase.

Sounds OK.

The namespace will be corrected in Zorba 3.0, there is already a merge proposal from Chris for this.
So please do not modify it, simply add support for a module that is missing the @project tag.

We went back and forth with this issue for some time in the past and this was the best solution we came up with.
My 2 cents:
-please support it in your merge proposal 'as it is now' (meaning handle the cases where the @project tag is missing, see functx module)
- as soon as you have a better replacement for the @project tag we will discuss it

> - Regarding the dependency graph, could you please put it back yourself? I was

It is NOT coupled with the old codebase at all.
Just revert all your changes in file doc/zorba/xqdoc/CMakeLists.txt as suggested.

Thanks,
Sorin

I have managed to create the documentation and the generation is very quick (even after you add all the functionality I still think it will be quicker than the old one).

I would have some remarks though:

1) the menu on the left in the modules.html page is broken:
here is what I get:
[...]
excel
excel
excel
excel
excel
excel
excel
excel
excel
excel

All 'excel' links point to the
http://www.zorba-xquery.com/modules/excel/text
module documentation.
Both cryptography links point to
http://www.zorba-xquery.com/modules/cryptography/hmac
and so on.

2) there is no page with all the functions that helps the user find a function by name
(please see function_index.html)

3) in the 'Namespaces' section: please make the namespaces links to the module documentation where this is possible
(for instance http://expath.org/ns/file should be a link to the EXPath Zorba module documentation)

4.1) in the 'Function Summary' please put back the hover text such that people know what is the connection between the pictures and function annotations
('S' means sequential, 'E' external and so on)

4.2) Also the pictures should be links pointing to the specs: for instance 'external' should point to http://www.w3.org/TR/xquery-30/#dt-external-function and so on.
That is because not all the annotations come from W3C, there are also Zorba ones like 'scripting' that has to point to doc/zorba/html/scripting_spec.html.

4.3) put back the pictures in the function description. Example:
instead of
append-binary#2
E S append-binary#2

5.1) there is no link to the actual XQuery module with a nice XQuery highlighting
This does not help for the external functions but it shows the actual implementation for the XQuery functions.

5.2) there is no links to the schemas with a nice XML highlighting

6) there are no examples

7.1) there is a bug in the 'Errors' section:
Please see for example append-binary#2:

Errors
    file:FOFL0004 If
    $file
    points to a directory.
    file:FOFL9999 If any other error occurs.

Instead of:
Errors
    file:FOFL0004 If <strong>$file</strong> points to a directory.
    file:FOFL9999 If any other error occurs.

7.2) same error is in the description of each function:
Please see append#3 function description.

8.1) the links to the Zorba documentation are broken.
See for instance http://www.zorba-xquery.com/modules/fetch and in the module description the link to the URI resolvers points to:
html/uriresolvers.html
instead of:
zorba/html/uriresolvers.html

8.2) the links to the FLWOR Foundation site and Apache from the bottom of the pages point to nowhere.
I'm reffering to the part:
Zorba is supported by the FLWOR Foundation and distributed under Apache Licence, Version 2.0.

8.3) please run the web-crawler that checks there are no broken links in the generated documentation
