The hasselt osm file is sime 12 MB, the colorful hasselt pdf file just below 1
MB so that's okay (3.7 sec processing time on my machine so if all claims are
right sub seconds on a fast new apple).
I finally tried this, hoping to replace my Maperitive workflow.
With a Bonn map from https://download.bbbike.org/osm/bbbike/ of 724 MB I
started it last night (~13 h before), and it still didn’t finish. No messages
after:
openstreetmap > processing file '/Users/hraban/Downloads/ConTeXt/Bonn.osm'
openstreetmap > original size 713811948 bytes, stripped down to 603309215
bytes
Maybe I should try smaller files ;)
We hit a limti in lpeg that allocates memory by duplicating the size
which then hits a top and falls back in allocating by + 1 every capture
which then kind of stalls the xml interpretation. I can hack that to
work (and need to check that with every lpeg update), but as we enter a
next stage in th econversion mem starts going virtual anyway and I see
my SSD being tortured so I aborted. More testing has to wait till I (if
ever) have a faster machine, with (say) 64GB super fast memory.
On my machine the still ok size is some 200MB.
