Extension talk:WSArrays

I get the warning

Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/html/extensions/WSArrays/src/classes/ComplexArrayPrint.class.php on line 141

when I try to caprint the array. The output is like expected but the warning shows up on the wiki page.

{{#caprint:test[2][Nr]}}

my test array:

1

• Nr: S2E1

2

• Nr: S2E2

3

• Nr: S2E3

Thank you for reporting this. It should now be fixed: https://github.com/WikibaseSolutions/WSArrays/compare/85d8463c91d06abaceb29a21648fc257e4fa743e...df548ca092c70210a7eb910c2a405ef584caa5ae

Would it be possible to implement somthing like php's array_diff to compute the difference between arrays?

Sure, this can definitely be added to the core extension. In the meantime, take a look at Extension:WSArrays#Writing extensions.

What's the recommended way of creating a copy of an exiting array?

Is it {{#cadefine:new|{{#caprint:old|markup}}}}?

Hi Planetenxin,

Currently, the easiest way to copy an array is by doing {{#camerge: new | old | }} I recognize this might be inelegant, and I will probably add a function for this down the road.

Hi folks, great extension! I recently tried to create a cross reference table based on the following data:

{{#cadefine:xref|((
"A01":["G 0.19","G 0.21"],
"A02":["G 0.19","G 0.21"],
"A03":["G 0.19"]
))}}

I'd like to use the same syntax pattern, even, if only one value is added, like in "A03". It seems, that "A03" is handled in a different way, because

* {{#caprint:xref[A01]|map|@@}}
* {{#caprint:xref[A02]|map|@@}}
* {{#caprint:xref[A03]|map|@@}}

returns

• G 0.19G 0.21
• G 0.19G 0.21
• Array

instead of

• G 0.19G 0.21
• G 0.19G 0.21
• G 0.19

Is this something you could fix?

Hi Planetenxin, thank you for your bug report. This issue is now fixed in version 1.1 (see https://github.com/WikibaseSolutions/WSArrays/releases/tag/v1.1).

Sincerely,
