The "Sync" button is also missing.

It's at Settings > Clipboard > External Sync.

Thank you.

The glider should turn red gradually, but an error message came up.

Code: Select all

I already answered this in another thread.

Will this bug be fixed in the future?
If so, it would be an excellent feature.

[rowett]

If so, it would be an excellent feature.

I'll put it on the backlog. It's not high priority so it may be a long time before it's added.

Both fixed in build 1184. Thanks for reporting!

[confocaloid]

In build 1185, when selecting some area, future events can depend on the direction in which the selection was performed. The expected behaviour is that the direction of performing a selection should not affect any future events.

• Select the state-3 Herschel by a movement diagonally from top-left to bottom-right, then press Ctrl+Space to advance selection by one tick. It works.
• Select the state-3 Herschel by a movement diagonally from bottom-right to top-left, then press Ctrl+Space to advance selection by one tick. It fails with "No live cells to select".
• Select the state-3 Herschel by a movement diagonally from bottom-left to top-right, then press Ctrl+Space to advance selection by one tick. It fails with "No live cells to select".

It's probably related to the "general errors" that have been appearing on the forums recently.

Crossposting what appears to be a LifeViewer bug (build 1191).

The rulestring "R2,C2,S,B0,2-3,8,NW0101010001000001000101010" appears to be translated into an alternating CA:

Code: Select all

R2,C0,S1,6-7,B,N@54422a|R2,C0,S1-8,B1,4-7,N@54422a

which doesn't match how the strobing CA with B0 but not Smax is supposed to work, and doesn't match how it works in Golly 4.3.

Changing to use custom neighbourhood (N@) instead of weighted neighbourhood also changes evolution of the patterns in LifeViewer build 1191.

This is the best rule of its kind that I could find:

Code: Select all

x = 255, y = 186, rule = R2,C2,S,B0,2-3,8,NW0101010001000001000101010
[...]

Edit:
oscillator:

Code: Select all

x = 3, y = 4, rule = R2,C2,S,B0,2-3,8,NW0101010001000001000101010
o$2bo$o$2bo!

Edit2:
this rule certainly has engineering potential

[...] When evolving the original pattern in LifeViewer build 1191, I believe the following rules are actually followed:

• for odd generations, use B14567/S12345678;
• for even generations, use B/S167.

Code: Select all

x = 60, y = 60, rule = R2,C0,S1,6-7,B,N@54422a|R2,C0,S1-8,B1,4-7,N@54422a

TL,DR: so far it seems to be a LifeViewer bug. When fixed, the rulestring you specified will no longer be interpreted to refer to the same cellular automaton, and the patterns will no longer work the same way. It seems like your CA can be equivalently defined in the following way:

Code: Select all

R2,C0,S1,6-7,B,N@54422a|R2,C0,S1-8,B1,4-7,N@54422a

In case fixing this appears to be too complicated at the moment, could you please temporarily disable support for CA with both B0 and weighted neighbourhood (NW), until this is corrected? The reason is that people are unknowingly posting patterns which rely on an incorrect interpretation of a rulestring with B0 and NW.

Can you disable emulation on B0 NW rules? They will only work on bounded grids.

Can rowett allow B0 NW rules on finite grids (without emulation)?

[confocaloid]

Why are you repeatedly posting unnecessary ridiculously long quotes, followed by short replies?

This case in particular is ridiculous, because you're basically directing at me questions that only the developer and maintainer of LifeViewer can possibly answer.

@unname4798 I will likely silently report any further posts from you that contain unnecessary overly long quotes, as violations of the forum rule that says that unnecessarily long/nested quotes should be avoided.

An additional complication with B0 NW is that B0 is not necessarily limited to strobing background. The NW... format allows to specify negative weights of neighbours. There can be two or more alive neighbours in neighbourhood positions whose weights add to zero (e.g. one alive neighbour in position weighted +1, one alive neighbour in a position weighted -1, and no other alive neighbours). Any such configuration would query the same birth condition (B0).

I don't know how much is explored re: CA with negatively-weighted neighbours, though.

What are known explored CA with negatively-weighted neighbours?
The NW... neighbourhood format allows to specify negative weights ("[...] The hexadecimal representation has the MSB as the sign bit [...]"). However, there seems to be little evidence of people actually using that feature.
