Resolving includes

Hi,
back to my questions on resolving modules includes.
I want to produce a .XQ file that includes all the code contained in imported modules (via import module clause). My purpose is to produce a maven plugin to do this.
I think such a code already exists in basex, and I would like to reuse it.
Any entry-point will be much appreciated.
Thanks in advance,
Christophe

I don't know anything about such a module. Where did you hear about it?
Cheers,

Well...
I suppose, you have such a code that reads .xq file, analyses imports, read and process imports, to build the full query with all functions attached.
But as finding a piece of code in a project you've never code on is a very long process, I thought you could help me to point out the main class in basex-core that does the job...
Best regards,
Christophe

I see. You could start with the QueryProcessor class [1]. However, I believe it's a fairly complex job you are tackling. Even if you did it manually, it would not always be clear how the merged representation should look like. See the following modules:
______ query.xq ______
import module namespace mod1 = 'uri1' at 'mod1.xqm';
declare namespace mod2 = 'c';
declare variable $mod2:v := 'VAR1';
($mod1:v, $mod2:v)______ mod1.xqm ______
module namespace ns = 'uri1';
import module namespace mod2 = 'uri2' at 'mod2.xqm';
declare variable $ns:v := $mod2:v;______ mod2.xqm ______
module namespace ns = 'uri2';
declare variable $ns:v := 'VAR2';How do you think should the merged query look like?

Well, it's not easy !
In my case, we use the same prefix/uri mapping in all files, and modules only declares function. Humm... I hope !
I'm going to look at QueryProcessor, and see what I can do. Maybe, I won't cover the whole XQuery syntax, but just a part, and with limitations. If my maven plugin can warn and/or thro errors, it will be good enough.
Thanks again,
Christophe
