Hi Ticker, yes, probably the value is still too small, and I assume nobody would mind to use a halo of 0.08 m width. Small problem is that we don't use this halo with the point in shape tests.

My understanding was that a high -precision unit was ~37mm at the equator (40,075*1000/2^24/2^6)*1000. With your change from 10mm to 20mm all the tests pass, but wouldn't private static final double EPS = 0.080; be safer, to allow for 2 hp roundings away from each other.

Hi Ticker,
I've looked at b14 again. The mp-cutting produces a point which is a small bit inside the real hole (~1.6 mm). I've attached the gpx files. e_hp is the tested segmet of the element b14, s_hp is the tested segment created by cutting, shape_hp is the complete shape produced by the mp-cutter. The southern end crosses e_hp. This small overlap is ignored when the merged shape is analyzed. Responsible for this is the method isOnOrCloseToEdgeOfShape(), I think I wrote it exactly for this problem but it is just a work-around for the problems produced by the polygon cutting.
Attached is a patch which might solve the problem, didn't test it much. It increases the allowed distance for "ON" from 1 to 2 mm and handles this special case.

Hi Gerd
Changes:
- Added comment in style-manual.txt about tools needed and how to generate the pdf. These are asciidoc, fop, python-pygments and mkgmap -pygments.
- Adjusted the layout of "Table 4.2. Style functions" so that is_in(...) doesn't run into the flags and and slightly changed the highlighting again.
- Changed log.info to log.debug.
- Added default: throw... to a couple of switch statements. I disagree with SonarLint that this is always good practice; here it is just pointless clutter.
I'm not sure what the problem is with commented code blocks. I left @override value() {...} in as commented because it clarifies what needs to change between a CachedFunction and a StyleFunction.
doc/styles/main.txt should be deleted from svn; it has been superseded by style-manual.txt.
Reg. b14. It might be slight rounding errors, but the hole generated from the merge of the 2 halves of the outer retains the 2 cut-points and this does match the inner polygon, whereas, for the inner polygon, isLineInShape gives IN/ON/OUT against one of the halves of the outer. I'd have expected the problems to be the other way around.

Hi Ticker,
no idea how the tool chain for the pdf works.
There are some commented code blocks and Eclipse and SonarLint warn about several missing default statements, e.g. Complete cases by adding the missing enum constants or add a default case to this switch. IsInFunction.java mkgmap/src/uk/me/parabola/mkgmap/osmstyle/function line 164 SonarLint On-The-Fly Issue
Reg. the TODO comment // problem with test b14 on the cut polygons and isLineInShape that goes away when merged. TODO: investigate sometime Maybe the reason is that we create a Coord instance at the place where the polygon is split. Due to the rounding errors this point can be a 1-2 mm inside or outside the original inner polygon. Merging should not change the result unless the added point is removed by the merge. In that case I would assume that there were no rounding errors.
Some log statements might be removed or changed to debug level? log.info("done", System.identityHashCode(this), hasIn, hasOn, hasOut);

Hi Gerd
I think this is about ready for release.
There is a slight problem with the layout in the Style Manual in that the width of "is_in(tag,value,method)" causes it to run into the Node/Way/Relation flags. If there was a way to put the function args down the first column it would fix it, but I have no idea of the rules of the formatting language. What are the tools used to transform doc/styles/*.txt to the style-manual.pdf?
I'm not going to be able to do any complex line->polygon in/on/out debugging in the next few days and it seems to work well for most cases.

Hi Gerd
Patch attached that:
- rewords the sentence is the Style Manual and changes the highlighting; I need to check the next build/download to see if this is clearer.
- fixes polygon 'any' method to also return true if exactly ON.
- merge polygons for 'any' so that line on shared boundary is "in" rather than "on".
- change the test driver to try all methods relevant to the element, checking they return true/false as appropriate. I decided that, rather than introducing a new tag saying which methods should match, it was clearer to use the 'expected' tag value as a description of how the element interacted with the polygons and generate the methods that should match from this and the non-matching from a list if all methods.
