lifeviewer bug

[azulavoir]

Please let me know which version of Android you are running. There haven't been any significant changes to LifeViewer recently.

This issue occurs in Chrome 120.0.6099.144 on Android 14.

[rowett]

LifeViewer identifies that 1-cell on-off has both active rotor cells, volatility, temperature and heat of 0 (which is impossible for any oscillator) even through it's period and mod is 2.

Code: Select all

x = 1, y = 1, rule = B3/S23Investigator
J!

Fixed, thanks. LifeViewer treats the off version of on-off [R]Investigator pairs as a dead cell during Identify.

Fixed, thanks. LifeViewer treats the off version of on-off [R]Investigator pairs as a dead cell during Identify.

Another bug: Strict voltility and voltility should be 1, as there is 1 cell that oscillates at that period. Heat should be 1, and temp should be 1.

They are. You need to hard refresh your browser to ensure you have the latest build (1098).

[b-engine]

Press Ctrl+A+Space and you'll see the bug:

Code: Select all

x = 5, y = 4, rule = R3,C2,S5-9,B7-9,N#
b3o$2b2o$5o$b2obo!

EDIT:
Lifeviewer identifies that the oscillator has minpop of 14, but it's minpop is actually 13.

Code: Select all

x = 6, y = 7, rule = Symbiosis
2.A$3.A$.A2.AB$.2A.A$A2.B$.2A$.B!

[rowett]

Press Ctrl+A+Space and you'll see the bug:

I don't see a bug. Ctrl+Space means advance selection after which use Enter to paste or Esc to remove.

On my system it shows min population as 13:

Yes that's expected. When you do Ctrl+Space it advances cells in the selection only which is shown as an overlay.

Bug:

1. Copy this text

2. Use the Copy all clipboard function on mobile

3. You do not get the rle, but this text.

If you're using Safari then this bug may have been fixed in build 1100.

Here's something like a bug:
if you move your mouse up, the "y" position in the bottom left hand corner goes down (at least on lazyslug.com)

I don't know if it's the most recent android or what but Lifeviewer is extremely flickery and barely functional on mobile for me.

Anyone else on Android experiencing this issue?

I'd love to know if it's just me and my Pixel 6a having this... it's definitely intrusive to Lifeviewing and it's still happening for me.

[snowman]

Galaxy S10 here, LifeViewer works fine for me.

[rowett]

Even on Safari it does not work.

I can't reproduce this. I've tested on both iOS and Android and it works for me. Anyone else seeing this issue?

[b-engine]

On my system it shows min population as 13:

-

This bug appears again. The infobox displays that the minpop is 30, but the identifier says that the minpop is 29.

[rowett]

The infobox displays that the minpop is 30, but the identifier says that the minpop is 29.

The infobox is showing the current population (not the minimum).

[b-engine]

The infobox is showing the current population (not the minimum).

But you can see that the current population value on the graph is the lowest.

EDIT:
Finally found that problem: the graph is slightly off-phase - it displays the latest population few generations before instead of current generation.

[rowett]

the graph is slightly off-phase - it displays the latest population few generations before instead of current generation.

This is only true when the number of generations T is greater than the horizontal resolution of the graph.

[azulavoir]

I'm not sure if this is a bug or what it is, but.... Whatever's going on here.

Both of these, which you'd think would be alternating rules between the two tables, are instead Symbiosis with the colors of HighAndLow. The order of the ruletables doesn't matter, and the order of the rules doesn't matter either. And if you leave the tables out, this just doesn't let you load the viewer.

Code: Select all

x = 0, y = 0, rule = Symbiosis|HighAndLowLife

I'm not sure if this is a bug or what it is, but.... Whatever's going on here.

LifeViewer does not support alternating rules where either of the rules is a RuleLoader (@TABLE or @TREE) rule.
It should flag this as an error.

EDIT: LifeViewer now reports these as not supported.

Identifying this oscillator (Pattern/Identify) shows that the minimum population is 246 and the maximum population is 476. After that, the section "Identify" in Help/Info says: "T Min/Max 246@T3 476@T14". However, generation 3 of the above pattern has population 270 (instead of expected 246), and generation 14 has population 436 (instead of expected 476).

However, generation 3 of the above pattern has population 270 (instead of expected 246), and generation 14 has population 436 (instead of expected 476).

It's because the T Min/Max values are an offset from the generation that the oscillator was detected. If you look a few lines further down in Help>Info>Identify you'll see "Generation 37 and 78". This means the oscillator was detected from generations 37 to 78 (hence period 41). The T Min value is 3 generations from the beginning (i.e. 37 + 3 = 40) and the T Max value is 14 generations from the beginning (i.e. 37 + 14 = 51).

[rokicki]

LifeViewer does not appear to stop propagation of keyboard events (even ones it processes) which leads to issues when you embed a LifeViewer in another context (such as a reveal.js presentation).

Code: Select all

<!DOCTYPE html>
<html>
<head>
<meta name="LifeViewer" content="viewer textarea"> <!--required tag-->
<script src="lv-plugin.js"></script> <!--assumes plug-in is in the same directory as html file-->
<script>
function showkey(e) {
   document.getElementById("disp").textContent += " " + e.code ;
}
window.onload = function() {
   document.getElementById("bubblediv").addEventListener("keydown", showkey);
}
</script>
</head>
<body>
<!--viewer container-->
<div id="bubblediv">
<div class="viewer"> <!--class=viewer is required-->
	<textarea>bo$2bo$3o!</textarea><br/> <!--textarea required in viewer container, with glider rle-->
	<canvas></canvas> <!--canvas required in viewer container-->
</div>
</div>
<!--end viewer container-->
<div id="disp"></div>
</body>
</html>

My workaround for now is to embed each LifeViewer in another div that swallows keyboard events, but that's
just masking the bug and can lead to other issues.
