It would be much easier to have a genenral negation i.e. !(expression) But in general you can rework any boolean expression by exchanging the operators, so that you coul go without a simple negation.

Re: [mkgmap-dev] ! not working -- problem with conditions in style-file.
Hi I think inventing such an operator would be a bad idea. It would be much easier to have a genenral negation i.e. !(expression) The style rules already allow general negation. If I've understood the conversation, then: !(tracktype 5) does exactly what Felix wants it to do. ..Steve ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] ! not working -- problem with conditions in style-file.
Hi However I think something like this won't work So would(!(tracktype5)|condition2=yes)work? Meaning either tracktype not equal smaller 5 or condition2=yes - one of the two has to match for it to not stop the action. Yes it would work. Here is an example, only WAY 2 is not converted. WAY 2 and 5 differ only in condition2=yes WAY 1 highway=track WAY 2 highway=track tracktype=3 WAY 3 highway=track tracktype=5 WAY 4 highway=track tracktype=fjdk WAY 5 highway=track tracktype=3 condition2=yes lines highway=track (!(tracktype5)|condition2=yes) [0x1] polygons results WAY 1: Line 0x1, name=null, ref=null, res=24-24 (1/1),(2/2), WAY 3: Line 0x1, name=null, ref=null, res=24-24 (1/1),(2/2), WAY 4: Line 0x1, name=null, ref=null, res=24-24 (1/1),(2/2), WAY 5: Line 0x1, name=null, ref=null, res=24-24 (1/1),(2/2), ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
[mkgmap-dev] ! not working -- problem with conditions in style-file.
There is a problem in the style handling. ! is not working. Assume I would like to reverse the statement layer0 into meaning layer 0 does not exist. Currently I could write layer!=-1 layer!=-2 and so on. But that sums up to quite a lot of text. Essentially I would like to have the following statement shorter...: ( tracktype!=1 | tracktype!=2 | tracktype!=3 | tracktype!=4 | tracktypeadded=yes ) but replacing it with (tracktype!5 | tracktypeadded=yes ) does not yield the same outcome. Have I got a logical problem, or is it mkgmap? ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev

The SGML start-of-comment ! comes closest. Is there a reason why you cannot use =, or is that not working either?

Re: [mkgmap-dev] ! not working -- problem with conditions in style-file.
Hello instead of ! you could use = or =. I don't know if there is a difference.

For example: ( tracktype=5 | tracktypeadded=yes ) I think he wants to have (tracktype!=* | tracktype5) The difference is, when there is no tracktype defined at all. For all ways that have no tracktype, I add a tracktype if I think a certain surface value reflects a tracktype. Then later on however, depending or not whether the tracktype existed naturally or was added based on surface, do or do not do an action. And this action is also dependant on the value of the tracktype itself. The full command working goes like this: sac_scale=hiking ((tracktype!=1 | tracktype!=2 | tracktype!=3 | tracktype!=4) | tracktypeadded=yes ) [0x07 ...] And I tried to shorten it by changing it to sac_scale=hiking ( tracktype!5 | tracktypeadded=yes) but this does not give the same result - because for tracktype=5 the condition of tracktype smaller 5 not existing was not fullfilled. (double negation - seams not to be like by programmers either...). Or in more detail so you can understand what I want. Below is the outcome I want to have for tracktype=1 and respectively tracktype=5 if tracktypeadded=yes THEN build 0x07 (no matter if tracktype exists, and no matter which value it has). if tracktype=5 THEN do build 0x07 (if tracktype does not exist, or tracktype has any value but 1-4 then it should also go through) if tracktype=1 but tracktypeadded!=yes THEN do not build 0x07 ((tracktype!=* | tracktype5) | tracktypeadded=yes) does not work because the outcome would be if tracktypeadded=yes THEN build 0x07 if tracktype=5 THEN do no build 0x07!!! if tracktype=1 THEN do not build 0x07 !!! is the problem. Because in case that neither tracktype is under 5 nor tracktypeadded=yes I still do want 0x07 to be built. What actually works and at the same time makes the command shorter is: sac_scale=hiking ((tracktype!=* | tracktype4) | tracktypeadded=yes) still I would fine sac_scale=hiking ( tracktype!5 | tracktypeadded=yes) to be more elegant and shorter (though yes I do admit, double negations do cause confusion). ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
