Pattern viewer for forum threads

[GUYTU6J]

New page!

One thing I've noticed is that the circular neighbourhood used by LifeViewer is actually different to the L² neighbourhood shown here.

Can this "Euclidean distance" neighbourhood also be supported (with suffix NL, say)? I can't think of any other programs that actually handle rules using this neighbourhood, so maybe this could be a first. I don't think it's particularly high priority to add support for this, though.

What's the difference between circular and L^2 (or L2, for search keywords) neighbourhood? I can only find some examples in this list, but I don't see an explanation on the forums.

What's the difference between circular and L^2 (or L2, for search keywords) neighbourhood? I can only find some examples in this list, but I don't see an explanation on the forums.

If r is the neighbourhood range then:
L2 (Euclidean) is the set of points <= r * r
Circular is the set of points <= r * r + r

Can we support custom definition of colors for CELLBORDERS, GRID and GRIDMAJOR, as well as their thickness?

[rowett]

Can we support custom definition of colors for CELLBORDERS, GRID and GRIDMAJOR, as well as their thickness?

GRID and GRIDMAJOR colors are already customizable: https://conwaylife.com/wiki/LifeViewer#Grid
CELLBORDERS are always drawn in the background color (LifeViewer simply draws grid lines in the background color).

Thickness is not customizable at the moment. I'll take a look at some stage.

...
CELLBORDERS are always drawn in the background color (LifeViewer simply draws grid lines in the background color).
...

Ooops, then there will be style inconsistency between my new viewer-based template:Nbh-demo and the old images. As can be seen in neighbourhood, the hypothetical COLOR CELLBORDERS should be set as 82 192 82 so as to signify the borders of neighbourhood.

Related, my newest revision to triangular neighbourhood is broken due to the invalid LE or LV following N in HROT notation. Should I edit them out (replacing with some weighted neighbours), or wait till LifeViewer begins to support them?

EDIT: is it known that the brightness of a LifeViewer thumbnail depends on its size? The effect can be seen under "Night mode" or "Dark mode" on mobile browser:

Compared with smaller viewer windows, which is about as bright as other static images, larger ones are significantly different.

No plans to have LifeViewer or Golly support LE or LV for HROT. You can replace with a Custom neighborhood.

LV would be R2,C0,S,B1,N@06E5C0L
LE would be R1,C0,S,B1,N@58L

Also it would be worth replacing "STARTFROM 1" in your template with "STOP 1 AUTOSTART NOREPORT". It will prevent the message briefly appearing.

It wasn't known (to me). There's nothing in LifeViewer that changes brightness based on size.

Thank you. How about the "6-cell triangular outer neighbourhood" and the "6-cell triangular inner neighbourhood"?

...
Also it would be worth replacing "STARTFROM 1" in your template with "STOP 1 AUTOSTART NOREPORT". It will prevent the message briefly appearing.

But there is NOGUI so that AUTOSTART STOP 1 is disabled. And why doesn't NOREPORT work with STARTFROM 1 ?

[rowett]

And why doesn't NOREPORT work with STARTFROM 1 ?

It does now. You also may wish consider adding NOCOPY since it doesn't seem helpful to be able the copy the RLE from what are effectively just neighborhood images.

LifeViewer's controls are flashing like crazy on a chromebook.

Please try build 653 and let me know if it helps. You'll need to hard refresh your browser.

Did you change something that causes LifeViewers to appear in more locations? They've popped up below the 'pattern RLE' boxes on Catagolue pages:

[rowett]

Did you change something that causes LifeViewers to appear in more locations?

Yes but it was for another use case. I've reverted the change so next refresh things should return to normal.

I've got the LifeViewer plugin js file from the link on the wiki. How do I instantiate the viewer on my web page? Any instructions available. Thanks.

Ok, that worked great. Now, if I type into the textarea, how do I get the viewer to refresh with the rle I typed?

[rowett]

One way is to add a button into the <div> containing the RLE:

Code: Select all

	<button type="button" onclick="updateMe(this); return false;">Update</button>

Excellent. Thanks. I have developed a LifeWiki tutorial for the plug-in which you may wish to review. It's currently on my User:Book page but I plan to deploy it to its own page soon.

You'll see I omitted the meta tag variations that I think are not needed for the tutorial, or are perhaps no longer needed as browsers etc. have changed since you wrote that post with instructions.

If you have any input, I'd appreciate it.

Here's PatMan (Pattern Manager), another use of the LifeViewer plug-in https://golhobby.com/patman/.

Would an option to zoom differently on different axes be possible to add such that square cells can be made to look like rectangles?

[muzik]

Code: Select all

#C [[ STARTFROM 102 ]]
x = 6, y = 6, rule = PCA_4
6.A$6.A6$5A5.A$5.A4.A6.A$.A2B.A11.A$A.2B2A$3A.A9.A2.A$2.A2.A8.A2.A4$
11.A$11.A2$11.A$11.A2$11.A$11.A!

Is Select All supposed to include history states? This was fixed for outer-totalistic rules, but PCA still seems affected, but I don't know if they're handled differently.

The bounding box results on Identify aren't always consistent for hexagonal patterns when rotated, so I don't know if they should be kept in the output.

Code: Select all

x = 5, y = 4, rule = B26/S2H

Code: Select all

x = 11, y = 7, rule = B26/S2H

Can Identify be made to state the generation a pattern dies at in a message like is done in normal playback?

Code: Select all

x = 161, y = 94, rule = B3/S23

I also noticed that Select All still creates a 1x1 selection box even on empty patterns:

Code: Select all

x = 161, y = 94, rule = B3/S23
5b!

In addition, Identifying the above empty pattern will advance it one generation and state that all cells died, but subsequent identifications correctly declare it an empty pattern (capitalized differently from the new pattern message).

Yes but unlikely to be a priority.
