Serious bug: paste any RLE into the box on the LifeViewer page (https://lazyslug.com), and click the view button; it doesn't respond when it should start displaying the pattern

Fixed, thanks!

Select this block and nudge it, then LifeViewer will say there's no room to nudge the block.

Fixed, thanks!

If you select one of the blocks and then change the rule, the other block will dissappear.

Code: Select all

x = 11, y = 2, rule = B3/S23
2o7b2o$2o7b2o!

This is by design. If there is a selection when you change rule then the new pattern only contains the cells in the selection.

Not sure if this is a result of the new URL scripting functionality, but at least at viewer.html it doesn't appear to be possible to define a custom URL by pasting it into the text box and clicking View.

Fixed, thanks!

It was related to a web server upgrade.

I've added similar functionality to the LifeViewer home page . Supports: rle - to define the pattern rule - to specify the rule (defaults to B3/S23 if not specified) name - to specify the name (creates a #N line in the pattern header) viewerconfig - to specify script command section Examples: rle ht...

I don't know of a better place to put this, but at the bottom of the page in lazyslug.com, "Anything copied to the clipbboard will also appear here." has an erroneous b.

Fixed, thanks!

This pattern no longer works how it used to - it appears to explode instead of travelling down and to the left.

Fixed, thanks!

Having said this I realised that for an oscillator of period p , in order for a specific cell to be oscillating at sub-period n , it must be alive for at least p / n generations. By computing the alive count per cell over period p (which is fairly inexpensive), I could use this information to quick...

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. Having said this I realised that for an oscillator of period p , in order for a specific cell to be oscillating at sub...

This has its period identified in less than three seconds, but spends a whole minute figuring out everything else. Potential target for optimization? x = 40, y = 22, rule = B2n3aeijy4ci5cr6n/S2aek3-acek4eiknr5ir6eik7e 38bo$38b2o$39bo5$31b2o$31b2o5$31b3o$31b3o2$28b3o$2o2bo23bo2bo$o27b2o2b 2o$2obo26b...

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.

*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...

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 h...

Another strange bug

Fixed, thanks!

oscar.lua incorrectly concluded that "This pattern is stable." after 563939073 generations and several hours of running it: x = 54, y = 2, rule = MarBlocks-5-rep o49bobo$bo48bo2bo! It's because the pattern in the previous generation hashes to the same value. The check for hash collisions fails sinc...

Using these steps I found that this is a bug with the Super algorithm, not with HashLife.

It's to do with HashLife. The RuleLoader version of LifeHistory also shows the same issue. Both RuleLoader and Super algos use HashLife.

(is it a bug or it has to do with HashLife?)
Steps to reproduce this bug (along with a description):
1. Run this pattern up to the moment when the loaves appear.

What generation does this happen?

2. Add one cell to the interior of the diehard.

Please give the XY location of this new cell.

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

You can see fake pattens if you zoom out.

I tried selecting the middle portion with a 2x1 selection, it turns out the selection is shifted one over.

This should be working now, thanks.

It seems like underscores in filenames can trigger bugs. Steps to reproduce: * Run Golly 4.2. * (Optionally) Draw some pattern in the pattern area. * Save the pattern under the filename "a__b.rle" (without quotes). (Note the double underscore.) * Close Golly, and run again. * The list "File -> Open...

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

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.

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 li...

All four of these rules still appear to be ruletable-based though, instead of being converted over to the [R]Investigator algorithm?

Done.

Also, I think I've asked this one before, but why don't layers do anything for 2-state rule tables?

Done.
