Hi Steve,
the evaluation of boolean options in mkgmap is a bit confusing. It is possible to specify e.g. --drive-on-left
This is the only documented form for this option.
Yes, that's true. I fear it was me who introduced the format var=true|false with the documentation of --remove-ovm-work-files I also used that with splitter, e.g. keep-complete=true|false I think I used it because it is common for tags.
do not have the same effect, and that is true for most boolean options, because typically we use this kind of evaluation: linkPOIsToWays = props.getProperty("link-pois-to-ways", false);
Oh well, perhaps everyone disagrees with me then :) I guess all those options were added before the "no-" prefix was available however.
My understanding is that the "no-" prefix is similar to removing the option, and with --check-roundabouts in combination with drive-on-right or drive-on-left it doesn't have the wanted effect, as it triggers the automatic detection. I agree that drive-on=right|left would be much better. Gerd
