Golly bugs

[eRroR_6o6]

Can you explain the details of how to reproduce the bug? I can't seem to reproduce it either in 4.3b2 or 4.3.

The bug only seems to happen when you reset the pattern while you're drawing the cell.

In Golly 4.3 icons in the state selector are off-center, and the icons in the file selector are different (and IMO worse). In the screenshot, top is 4.2b1, bottom is 4.3. I'm using MacOS 14.1.

I tried to run the following rule with 3 states (air, ice, water) in Golly 4.3:
-If air is adjacent to 3 ice cells except the a3 configurations, then it will be an ice in next generation.
-If ice is adjacent to 2 or 3 ice cells, then it stays being ice.
-If water has at least 1 ice neighbor on west, south or east, it will be an ice.
-If non-ice has water on north and non-ice in both upper corners, it will be a water.
-Ice turn into a water which turns into an air by default.

For some reason it doesn't work. The invalid behavour of Golly is presented in the video below. It works in LifeViewer, so I don't know what's going on.

symmetries:reflect_horizontally is invalid. it should be reflect_horizontal.

I fixed it and it still doesn't work.

Can you provide more details on which patterns don't appear to evolve correctly?

I tested the following pattern in Golly 4.3 and in LifeViewer build 1226. It appears to work the same way in both cases. In particular generation 100 shows population 476 and bounding box 27-by-112. Is that as expected, or it is supposed to evolve differently?

AB2.B3A$2.BA.A.A.B$A5.BABA!

...

In LifeViewer it evolves exactly as I wanted, but it still doesn't evolve correctly in Golly.

EDIT: I changed the name of the rule to IceB and it works! I think that Golly behaved incorrectly because first version of this rule was incorrect and Golly 'remembered' it, unaware that meanwhile the rule changed. It's still an error to fix.

Which version of Golly you are using?

[...] It's still an error to fix.

I think this isn't an error. To replace the existing copy of a .rule file, you can simply copy the new version into clipboard and do Ctrl+Shift+O ("Open Clipboard"). It should ask for confirmation before overwriting the existing file.

Golly 4.3.

I didn't know that... Sorry for wasting your time...

That feature could be more visible than it is, but then probably some other feature would become less visible/less discoverable.

Some features can be found by looking through the supplied documentation, or looking through the menu items, or looking through the "File -> Preferences" dialog (and asking on the forums or reading an earlier discussion).

In Golly 4.3 icons in the state selector are off-center, and the icons in the file selector are different (and IMO worse).

Yep, I see the same issue on my Mac. It looks like a regression due to building Golly with a newer version of wxWidgets, so I'll try to fix it for the next release (probably much later this year).
