Not sure if this is causing any issues elsewhere but there appears to be a misspelling in this code file:

No issue. That's just a label that Help>Memory uses. Well spotted though!

The "Symbiosis" rule table crashed.

Please post an example pattern that crashes.

The rule "R1,C3,S2-5,B6,8,NW111101111,110" and similar rules are completely broken, acting as if they were somehow B0 Generations rules. Thanks for the report. The algo shouldn't allow a non-zero dead state weight (i.e. the first digit of ,110 ) since this leads to B0-type behaviour which is not su...

If you add bounded grid specifications after an alternating rulestring, it works just fine. But if you go to Settings > Pattern > Change Rule, the bounded grid suffix appears after both rules that are being alternated.

Thanks for the report. Fixed in build 1384.

Build 1384 is now available on the lazyslug server

Fixes in this build:

• fixed missing error message
• fixed Change Rule adding extra bounded grid specification

no error message is shown for this pattern...

Thanks - it was reported just above. See the post above yours for the answer.

The pattern in this post fails with a blank error message. I'm not sure what the issue is but it's probably worth making it show something other than an empty string. Thanks for the report. This issue is that the RLE is invalid since it is splitting a count from a symbol across the end of a line. I...

Finally, level 30!

Hexagonal custom rules will show information about defined icons in Help > Info > Pattern but won't show the icons themselves unlike for square grid rules. Is this intended? Yes, the information about the defined icons comes from the parser. It's interesting to see that they were found and were val...

How does POLYFILL decide how to colour intersecting polygons? Each polygon is drawn separately so if you overlap different polygons with alpha they will blend in the intersection. For single polygons the non-zero winding rule is used. I'm not sure about other users but there appear to be a few more...

These two patterns run in LifeViewer, but are rejected by Golly. Is this expected behaviour? This is expected. For those rules LifeViewer supports B0 without Smax whereas Golly does not . Put the mouse cursor on one of the two highlighted cells and they'll be shown as [bounded] 0 rather than [bound...

Build 1380 is now available on the lazyslug server

Fixes in this build:

• fixed cell information for hexagonal bounded grid top-left and bottom-right cells
• fixed PCA Icons initial colours

Is it intended that the code boxes in this post are unopenable and result in an error? Yes since they both have illegal RLE headers: x, y, rule = M0,14,13,3,11,5,6,8,7,9,10,4,12,2,1,15 RLE headers must have a space or = after x . The parser is assuming the x is a pattern state and then correctly co...

Open the cell map for this and switch between period and frequency modes. There appears to be a pixel at the bottom right of the grid which is absent in period mode but correctly present in frequency mode.
