Overpass API developpement

["sly (sylvain letuffe)" <>]

I was missing a simple to use export API that could provide gpx output 
without fighting too much with local tools (read: accessible to non system 
gurus).
Such as incorporating a dynamic link to a mobile app, easy link to 
up to date download.

Before messing with overpass patches (My C pramming skills have degraded 
since studies), 
I tried a hacky proof of concept by creating an API wrapper that would query 
the overpass for an osm output and then convert that back to gpx and send it 
to user.

That wrapper is here :
https://github.com/osm-fr/osm2node

And a demo/production :
http://api.openstreetmap.fr/osm2nodegpx?data=node[%22shop%22]%2845.57,5.845,45.60,5.978%29;out%20body;%3E;out%20skel%20qt;

With time and beta testers, I found that "generating gpx from osm" is 
obviously
non bijective, One might like the fixme=* be converted to <name>
some the shop=* be converted to <type>

The possibility to customize output, the csv output allows
to choose :
[out:csv(name,shop;true;";")];
Would probably be of intereste as well.

Mmd told me there is some restructuring of output's code, 
I have no hurry at all, so I'll wait, but that was just to let you know.
