<nowiki>{{#show:Brazil| ?In OECD}}</nowiki> yields "{{#show:Brazil| ?In OECD}}"
<nowiki>{{#show:Brazil| ?In OECD}}</nowiki> yields "{{#show:Brazil| ?In OECD}}"


<nowiki>{{#if:| yes | no}}</nowiki> yields {{#if:string| yes | no}}
<nowiki>{{#if:string | yes | no}}</nowiki> yields "{{#if:string| yes | no}}"
 
<nowiki>{{#if:{{#show:Brazil| ?In OECD}}| yes | no}}</nowiki> yields "{{#if:{{#show:Brazil| ?In OECD}}| yes | no}}"
 
<nowiki>{{#if:{{#show:France| ?In OECD}}| yes | no}}</nowiki> yields "{{#if:{{#show:France| ?In OECD}}| yes | no}}"
 
Thus:
 
<nowiki>{{#if:{{#show:Brazil| ?In OECD}}|Category:OECD|}}</nowiki> yields "{{#if:{{#show:Brazil| ?In OECD}}|Category:OECD|}}"
 
<nowiki>{{#if:{{#show:France| ?In OECD}}|Category:OECD|}}</nowiki> yields "{{#if:{{#show:France| ?In OECD}}|Category:OECD|}}"
 
Thus:
 
<nowiki>[[{{#if:{{#show:France| ?In OECD}}|Category:OECD|}}]]</nowiki> yields "[[{{#if:{{#show:France| ?In OECD}}|Category:OECD|}}]]"
 
But the [[ ]] codes do not make it a valid category definition.
 
 
What about
 
<nowiki>{{#if:{{#show:France| ?In OECD}}|[[:Category:OECD]]|}}</nowiki> yields "{{#if:{{#show:France| ?In OECD}}|[[:Category:OECD]]|}}"

#IF parser function

{{#show:Albania/OER| ?Has capital|link=none}} yields Tirana

{{#show:Hungary | ?In OECD}} yields "true"

{{#show:Brazil| ?In OECD}} yields ""

{{#if:string | yes | no}} yields "yes"

{{#if:{{#show:Brazil| ?In OECD}}| yes | no}} yields "no"

{{#if:{{#show:France| ?In OECD}}| yes | no}} yields "yes"

Thus:

{{#if:{{#show:Brazil| ?In OECD}}|Category:OECD|}} yields ""

{{#if:{{#show:France| ?In OECD}}|Category:OECD|}} yields "Category:OECD"

Thus:

[[{{#if:{{#show:France| ?In OECD}}|Category:OECD|}}]] yields ""

But the [[ ]] codes do not make it a valid category definition.


What about

{{#if:{{#show:France| ?In OECD}}|[[:Category:OECD]]|}} yields "Category:OECD"
