[mkgmap-dev] possible echotags enhancement?

Hi Ranko,

I don't fully understand what you are trying to do. I fear this is not always possible to report the original element. For some ways with a so-called "fake id" there is no real element in OSM, e.g. the ways generated by the --precomp-sea  option.
Anyhow, I've also missed that feature in the past.
Attached is a quick hack to add either node,way, or relation after the string "generated from ". I didn't test it well. Please check if it helps to solve your problem.
The binary is here:

echotags style command displays the element type and original OSM-Id (as in "Node generated from <OSM-Id>").

Would it be possible to additionally display the original element type for all such "generated from" elements?
(Something like "Node generated from Way <OSM-Id>" or "Way generated from Relation <OSM-Id>")


At the end of my style file I use echotags to log elements left unhandled and then process this logfile to generate a html file with direct links to offending elements in OSM.
This way I can click and easily correct the data in OSM if needed.
A href tag generated this way looks like this: <a href="https://www.openstreetmap.org/way/688658542"<https://www.openstreetmap.org/way/688658542>>OSM link</a>

To do this I need to detect the (original) element type from the echotags message (is it a node/way/relation),
but for "generated from" elements there is no way to detect this properly from the echotags message text.

For example: with the "--add-pois-to-areas" option a node is generated for each polygon or multipolygon.
However, the message is the same for both and there is no way to detect if the original element was a polygon ("way") or a multipolygon ("relation") :(
