Using fragments in if statements [message #1720863]

Hello.

I am using the following fragment to display values in SpecObjects and Specification in reqif10 models:

<fragment name='getValue'>
<arg name='specElement' type='reqif10::SpecElementWithAttributes'/>
<arg name='attribute' type='String'/>
[for (value:AttributeValue|specElement.values)]
[if(value.eGet('definition').longName=attribute)]
[value.eGet('theValue')/]
[/if]
[/for]
</fragment>

However when I try to call this fragment in a if statement such as :

[if(purpose.getValue('visible in doc') = true

[if(purpose.getValue('visible in doc') = 'true'

it does not work. Is it possible to let fragments return something so they can be used in conditional statements? This variable 'visible in doc' is defined as boolean in the reqif10 model. Just to be clear, the fragment works fine when showing the content in the document.

best regards
Axel Thor

Hello
fragments are sub templates so the content is inserted in the doc,
What you want to achieve is a query I think the best in your case is to create a plugin library which will contain your queries.

I will post here asap a process to do this

EDIT : instructions to create queries are listed in this post : https://www.eclipse.org/forums/index.php/t/1065528/

Thanks for this Smile

I was also able to set global variables using gPut in the fragment and then gGet in the <gendoc> section to check the value. Using acceleo modules is obviously a better way to accomplish this.

Having said that, can you explain to me this scenario:

[specObject.getValue('text')/]<drop/>
<image keepW='true' filePath='[gGet('figure_dir')/][gGet('returnValue')/]'><drop/>
 an image
</image><drop/>
[/if]<drop/>
[if (specObject.type.longName = 'Capella Diagram')]<drop/>
[specObject.getValue('text')/]<drop/>
<image keepW='true' filePath='[gGet('capella_diagram_dir')/]/[gGet('returnVAlue')/].jpg'><drop/>
 
</image><drop/>

When I call getValue fragment which runs gPut('returnValue....) twice in the same <gendoc> section, the only way to access the different return values is to run gGet('returnValue') the first time, and then gGet('returnVAlue') the second time etc. I.e. I always have to change a little bit how the 'returnValue' string is written every time I call getValue.

Hello
Acceleo has a cache which returns always the same value for the same input

You can disable the Acceleo cache (take care of potential performance problems) using :
Window > Preferences > Toggle the cache of evaluation queries
