<div dir="ltr"><div>It is a complex issue, let me try to summarize my understanding of it<br><br></div>* We support multiple toolkits and we need a good to find out which toolkit each activity uses.<br>* IMO trying to figure that out by analyzing the code is not good. Too complicated and too fragile.<br>
<div><div><div class="gmail_extra">* We have a decent way to detect the toolkit by looking at the exec line. Unfortunately that doesn't works for gtk3 vs gtk2 because we (mistakenly) didn't make multiple sugar-activity installable in parallel.<br>
</div><div class="gmail_extra">* Another possible way to handle it would be to have an explicit toolkit property in <a href="http://activity.info">activity.info</a>. That would require to update either all gtk3 or gtk2 activities though.<br>
</div><div class="gmail_extra"><br></div><div class="gmail_extra">So, all in all I don't see a satisfactory solution to distinguish gtk2 and gtk3. Given that gtk2 has been long deprecated I tend to think we should just give up with that. Let's spend time porting activities instead :) For the future looking at the exec field seems good enough. So if we ever release a gtk4 toolkit we should have a sugar-activity-gtk4 script.<br>

</div></div>So, do we agree to have toolkit type and version in the <a href="http://activity.info" target="_blank">activity.info</a>?<br>
We have a pull request on this:<br>
<br>
<a href="https://github.com/sugarlabs/sugar-toolkit-gtk3/pull/104" target="_blank">https://github.com/sugarlabs/sugar-toolkit-gtk3/pull/104</a><br>
<br>
I'm fine with this. I think we need two versions: minimum and maximum.<br>
This is the same <a href="http://activities.sugarlabs.org" target="_blank">activities.sugarlabs.org</a> has.<br>
