Pattern viewer for forum threads

Identify on this gives an unexpected result: the mod is a quarter of the period, but the transform provided is FlipX, which is only usually given if the mod is half the period

Fixed, thanks.

Also, why is "LifeH" considered a valid alias for B3/S23H despite it not being mentioned in the in-viewer list of aliases, but LifeL isn't a valid alias for B3/S23L?

Because it was in the list of aliases but in the wrong category. It's now in the right category.

Despite being range-1, the edge of the grid seems to be far more eager to kill rule table patterns than other range 1 patterns

Fixed, thanks.

This 2016 pattern is now giving an error: viewtopic.php?f=3&t=1622&start=125#p26626

Fixed, thanks.

This also gives an error due to the use of a deprecated command, so I'm not sure if you'd want to fix this

No.

Same problem here with a deprecated script command, though I'd honestly prefer it if SQUAREDISPLAY and HEXDISPLAY were reimplemented

Fixed the pattern. Use [[ SQUARECELLS ]] and [[ HEXCELLS ]].

This post and several below it still links to the old .biz site that no longer works: viewtopic.php?f=3&t=1622&start=375#p66596

I've fixed some.

Identifying this will cause it to die at the border, but the viewer still says "Identifying..." instead of stating a time of death. The viewer also reports a negative amount of living cells, which is obviously an impossibility.

Fixed, thanks.

Selections appear to be bugged - Select All only targets a single cell here (that isn't even alive):

Code: Select all

x = 4, y = 4, rule = x-rule
o$o$bo$2b2o!

Using Select All and then random filling on this puts cells in the completely wrong place:

Code: Select all

x = 200, y = 200, rule = Movingstrings:T200,200
90$6bobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobo

AUTOFIT might be doing something weird here, since after all cells die it zooms in to the max on an area untouched by cells.

Code: Select all

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

[[ AUTOSTART AUTOFIT THEME Book ]]

This same pattern with the same script commands creates a p2 cell in the Margolus rulespace which is entirely absent in other 2-state rulespaces:

Code: Select all

x = 1, y = 1, rule = B/S
!
[[

PASTET EVERY 8 5 PASTE o! 3 0
PASTET EVERY 8 6 PASTE o! 2 -1
PASTET EVERY 8 7 PASTE o! 1 -1
]]

Code: Select all

[[

If we use the THEME command to specify a theme that does not exist, the name of that nonexistent theme will be misinterpreted as a command.

Code: Select all

x = 1, y = 1, rule = Life

[[ THEME Invalid ]]

This post and one below it still uses the old [R]Extended terminology making the pattern invalid: viewtopic.php?f=3&t=1622&start=3175#p165740

It seems like paste commands can create new dead history cells out of nowhere. For hexagonal and triangular rules, these don't render if hexagonal or triangular cell shapes are in use in some cases.

Code: Select all

x = 3, y = 2, rule = B/S
!
[[ AUTOSTART PASTET EVERY 50 PASTEMODE COPY PASTE 3b! 0 -1 ZOOM 3 ]]

Code: Select all

x = 3, y = 2, rule = B/SH
!
[[ AUTOSTART PASTET EVERY 50 PASTEMODE COPY PASTE 3b! 0 -1 ZOOM 3 ]]

Code: Select all

x = 3, y = 2, rule = B/SL
!
[[ AUTOSTART PASTET EVERY 50 PASTEMODE COPY PASTE 3b! 0 -1 ZOOM 3 ]]

I'm not interested in fixing these sorts of issues (same with the COLOR command). If you have script command errors you need to go fix the script anyway at which point these messages will disappear.

Same here: I'm not interested in fixing old posts that are now obsolete because LifeViewer has changed.

Some performance tests:

Results on Windows 10 using Brave (old system, so it isn't going to be fast):

Go To Gen 174762b:
- [R]Standard: 3.4s
- [R]History: 3.8s
- [R]Super: 16.9s
- [R]Investigator: 22.8s
- Ruletable: 8.9s
- Margolus: 4.1s
- General range: 18.6s

Identify:
- [R]Standard: 21.3s / 28.1s
- [R]History: 31.1s / 38.1s
- [R]Super: 59.5s / 79.9s
- [R]Investigator: 46.3s / 68.5s
- Ruletable: 27.8s / 39.1s
- Margolus: 16.3s / 22.7s
- General range: 60.5s / 77.5s

In this case, [R]Investigator Identify detected periodicity at around 220K generations in, whereas other algorithms only found it at around 330K.

[muzik]

A tiny feature request: would it be possible to add density for oscillators on bounded grids to the Identify results (min/max/average) so we can calculate the density values for periodic agars?

[muzik]

In some cases the Identify period map does not appear to include the deathforcer cells at the edges, but at other times it does:

Code: Select all

x = 13, y = 2, rule = B2ae/SSuper
FM.M5.M.MF$FM.M5.M.MF!

The limit for how far out you can draw (or change cells via selection) appears to be earlier than the limit for how far out selections can be made (before they do that buggy "snap to the edge of the grid" thing):

Code: Select all

Another strange bug:
1. Select the c/5d spaceship.
2. Advance the selection by using Ctrl+Space.
3. Observe the red cells.
4. Click on one of them so the green selection disappears but the red cells still exist.
5. Click the hand button so that the green selection is back but the advanced spaceship is deleted.
6. Run the resulting pattern for c. 500-2500 generations. It depends on the speed of simulation.
7. The pattern disappears but the live cells statistic still has alive cells!
8. Even stranger things happen when you rewind the pattern or return to the starting generation. It's hard to explain.

Another strange bug

Fixed, thanks!

[confocaloid]

A vague feature request: allow to put multiple RLEs in a single viewer, with ability to "page through" patterns one-by-one. This would be different from putting a single stamp collection:
- it would be easier to view patterns one-by-one,
- one could use bounded grids for individual patterns,
- maybe it would be possible to use different rules for different patterns.

Maybe something like this (here there would be two patterns in different rules):

Code: Select all

#C [[ MULTIPLEPATTERNS ]]

#C p6960 in a rule mentioned in https://conwaylife.com/forums/viewtopic.php?p=168651#p168651

A vague feature request: allow to put multiple RLEs in a single viewer, with ability to "page through" patterns one-by-one. This would be different from putting a single stamp collection

It's already possible to do this in your own web page. See here for an example.

I'm not sure of the benefit of having this on the forum since it makes it harder to copy and paste individual patterns.

You can also already use POIs to pan to different areas of a larger pattern (like the Exploratorium). You could also separate different areas of the pattern with [R]History/[R]Super state 6 cells.

[Haycat2009]

1. Please add Grounded Life (B35/S23) to the aliases. I think that this name has been in use for long enough.
2. Please add the ability to copy objects from one life viewer and paste it on another.

*What's the name of a multi-pattern command?

[rowett]

*What's the name of a multi-pattern command?

There is no multi-pattern command.

LifeViewer has a web page setting that tells it how to deal with the patterns it finds while scanning the page. The default is to display viewers inline and/or add "Show in Viewer" links. This can be changed with a meta setting to put LifeViewer into Multiverse mode.

In Multiverse mode there is only a single Viewer displayed which initially shows the first pattern on the page. The Page Up and Page Down keys can be used (when the Viewer has focus) to switch forward and back through the patterns. There are Next and Previous buttons also for this in the Settings menu.

See here for an example. You can switch Multiverse mode on and off with a link at the top and see the difference.

[H. H. P. M. P. Cole]

A big fat list of suggestions:

Add rule support for:
1. Isotropic Far Corners and Far Edges combined (use Hensel notation):

example: for this neighbourhood:

Code: Select all

x = 7, y = 7, rule = B/S012345678History
3.A$.A3.A2$A2.C2.A2$.A3.A$3.A!

the argument at the end should be F(3,2)
first number is orthogonal distance of edges, and second number is diagonal distance of diagonal cells

2. Isotropic Knight for any combination of x and y (use CAViewer notation):

example: for this neighbourhood:

Code: Select all

x = 7, y = 7, rule = B/S012345678History
2.A.A2$A5.A$3.C$A5.A2$2.A.A!

the argument at the end should be K(3,1)
the two arguments should be commutative.

3. Isotropic R2 Cross for any combination of two orthogonal distances
4. Isotropic R2 Saltire for any combination of two diagonal distances
Both must use CAViewer notation.

5. (This is trivial, but) Isotropic vN R1.
6. Add apgtables.
7. Add Factorio as an alias for R3,C2,S2,B3,N+.

This is to make LtL more accessible, and I did not cover R3 Cross (personally my fav rulespace) or R2 vN simply because THERE ARE TOO MANY TRANSITIONS. Mad respect to you, rowett, for giving us the gift of an accessible software.

Bonus points if you can let Golly natively handle these as well.

Links to learn about R3 Cross (both by me). Also, I have a userpage on the LifeWiki.

While we're on the subject of updates: could Grounded Life be added as an alias for B35/S23?

[Haycat2009]

1. Please add Grounded Life (B35/S23) to the aliases. I think that this name has been in use for long enough.
2. Please add the ability to copy objects from one life viewer and paste it on another.

While we're on the subject of updates: could Grounded Life be added as an alias for B35/S23?

The community has already decided that B35/S23 is Grounded Life. O powerful admins, can you please add Grounded Life as an Alias for B35/S23?

[rowett]

Please add Grounded Life (B35/S23) to the aliases. I think that this name has been in use for long enough.

Added. Though be careful when using aliases since it will make your pattern incompatible with other tools that don't understand the aliases.

There is just a lot of computation required for this pattern: the evolution of 34040 active cells across 29400 generations for 71 different sub-periods, none of which have a match.
