Go to declaration across modules

[robwhitby]

Auto-complete correctly suggests variables and functions from imported modules, but the go to declaration feature doesn't work, it just says "Cannot find declaration to go to".

Hi, will take a look at it.
Would you be able to prepare an example project that simulates it?

Thanks!

Hi, thanks and sorry for the delay getting back to you. Should "go to declaration" work across files? Maybe I don't have something setup right.

Create a library module lib.xq

xquery version "3.0";
module namespace lib = "lib";

declare variable $foo := "foo";
declare function bar() as xs:string { "bar" };

and a main module main.xq

xquery version "3.0";
import module namespace lib="lib" at "lib.xq";

$lib:foo, 
lib:bar()

The auto-complete works fine - typing lib: suggests foo and bar, but the go to declaration doesn't work on either foo or bar.

I'm using 0.0.9 btw.

Thanks again
Rob

Hi,

No worries.

As I thought the issue is not really related to the multi-module setup but the fact that marklogic has a bit more relaxed rules around variable declaration.
I prepared the logic for resolution of variables according to xquery language spec (http://www.w3.org/TR/xquery-30/#id-variable-declarations) which says:
"All variable names declared in a library module must (when expanded) be in the target namespace of the library module [err:XQST0048]. "
But marklogic doesn't throw this error (checked just a moment ago).

If in your library module you'll add prefix in your variable declaration then it'll start working fine.

Anyway... I'll try making resolution more relaxed as I think that most of marklogic xquery code uses this "feature" of not having to add prefix in variable declaration.

After some reading... It's probably a hidden feature nowhere described similar to defaulting function namespace for library modules to module namespace (http://docs.marklogic.com/guide/xquery/enhanced#id_20838).

ah I see, thanks for looking into it. I didn't realise it was a MarkLogic thing to default variables and functions to the library namespace - I write all my code like that :)

Will require selecting xquery "flavour" (creating a facet) for solving. Will go with next release.

Set in [File | Settings | Project settings | XQuery | Other | XQuery flavour] value MarkLogic and should work fine now.
