lifeviewer bug

[mniemiec]

I just noticed a bug only started happening yesterday. Every single pattern I bring up displays an overlay that says, "If there are no cells displayed, click on Help". Does anyone know why this is happening?

Yup, I believe that's not a bug, that's a feature -- i.e., a deliberate temporary change that Chris has made to LifeViewer, to get the message out to current users of LifeViewer in Chrome, about implementing the workaround. Haven't heard specific plans, but it would seem to make sense to remove that message after a week or two, since it will be more in-the-way than useful after a while.

Code: Select all

x = 8, y = 3, rule = LifeHistory
C6.E$A6.A$C6.E!

The 2 blinkers are the same in generation 1 but diverge in generation 2.

I'm currently using Chrome Version 105.0.5195.127 (Official Build) (64-bit), and see no problems.

Which operating system are you using?

I'm currently using Chrome Version 105.0.5195.127 (Official Build) (64-bit), and see no problems.

To clarify: you're using Chrome 105, you don't have Out-of-process 2D canvas rasterization set to Disabled in chrome://flags, and you don't see a slowdown in patterns such as the Exploratorium? I was seeing "reasonable" evolution rates for very small patterns before putting in the workaround, but the Exploratorium was running at multiple seconds per tick.

If he's on Linux then he won't be hitting either issue (no cells or slowdown), since Out-of-process 2D canvas rasterization is Disabled by default on Linux.
I've amended the warning that LifeViewer displays on start so it only happens on Windows.

LifeViewer's [R]History implementation differs slightly in that mark1 cells remain mark1 cells (after transitioning through markOff) rather than becoming mark2.

I'm getting about 30 fps on that, when I drag the speed bar up to maximum x64.

After looking at it for the first time in a while, it seems that LifeViewer can't load rle.
I can't seem to change the state of the cell.

I'll need some more details and an example of what you're trying to do.

Apparently it was the influence of Out-of-process 2D canvas rasterization.

[[ ]]'s require spaces around them to be picked up as commands. Is this intentional?

Code: Select all

x = 12, y = 18, rule = DeadlyEnemies
3.2B$3.2B6$.2B7.2B$.2B7.2B3$3A5.2B$2.A5.2B$3A3$.2B$.2B!

(Noticed when I took a look at this.)

Yes, the spaces are part of the syntax.

Crossposting this from another thread - was anyone able to reproduce this? Is this due to presence of several large viewers on the linked page? I just attempted again opening the thread thread Updated oscillator stamp collection (was: Re: Golly suggestions) in Firefox 105.0, and the same problem occurred.

When I try to open the following link in Firefox, the browser quickly eats all available memory. I do not know if this is an issue with the linked thread, with my system or both, but I was able to reproduce this on another computer.

When I am editing a post I made with a rule that is <s>not yet recognized by LifeViewer</s> pasted at the end after the pattern (edit: whoops, I already had mentioned the rule elsewhere) and I copy cells and go to paste it in the text box, it pastes nothing. The x=NNN, y=NNN header is correct, but the body is just a single solitary !. And, no, my selection is not empty.

I can't reproduce this. Please post an example.

Ok, try this:

Code: Select all

x = 0, y = 0, rule = ruleforbug153180
AB.AB.AB!

@RULE ruleforbug153180

@TABLE
n_states:3
neighborhood:Moore
symmetries:permute
1,0,0,1,0,1,0,0,1,2

Hit reply on this post, click preview, scribble something, copy, and then try to paste it back into the code box.

Edit: somehow this doesn't seem to work. The rule table format looks okay, but somehow it says "test123: rule lookup failed 404." Maybe it has something to do with the rule being pasted in after the pattern and being recognized in the wiki...

The rule table is invalid. There are not enough numbers on the final line of the definition.

Fixed it now. I can't reproduce the bug either, at least with that example, so maybe it has something to do with the rule table being in two places (pasted at end and the wiki) and LifeViewer gets confused.

LifeViewer only goes to the Wiki if there isn't a valid rule in the comments.

Not sure what was going on, then. Must have been a cosmic ray.
