Could redirects in the Rule namespace function as rule aliases? Example: Rule:ExtendedLife would cause this post to have a valid rule name.

Will LV ever support odd Wolfram rules?

B0 and S3:
Take integer (177)
Convert to binary (10110001)
Reverse bits (10001101)
Negate bits (01110010, rule 114)
Run

Code: Select all

#C W177 emulated
x = 1, y = 1, rule = W114
o!

Code: Select all

#C W215 emulated
x = 1, y = 1, rule = W20
o!

B0 without S3:
Take integer (81)
Convert to binary (01010001)
Negate bits (10101110, rule 174)
Run on even
On original, reverse bits (10001010, rule 138)
Run on odd

Code: Select all

#C W81 emulated
#C pffff it looks the same as W174 only
x = 1, y = 1, rule = W174|W138
o!

Code: Select all

#C W99 emulated
x = 1, y = 1, rule = W156|W198
o!

I believe I've finally found a way to consistently reproduce that massively annoying bug with the viewer jumping to the tapped position and becoming permanently stuck there that I've been experiencing for months. iPad Air 2, iPad OS 13.5

1. Go to this post viewtopic.php?f=3&t=1622&start=1500#p88581
2. Tap show in viewer
3. Tap somewhere inside of the viewer
4. Use the close button on the viewer
5. In one swipe, scroll down to the next code box with a viewer link
6. Tap show in viewer
7. Tap somewhere to the left of the screen outside of the viewer, and then the window should jump to that position and become fixed there until the page is refreshed.

I'm not sure if this is fixable or if it's completely the fault of apple, but it's been driving me mad - and if it can drive someone like me mad it should be locked up in a high security facility due to being a severe mental health hazard to the rest of humanity. Please fix this if you can!

Build 523 just published may fix this. I don't have an iPad so it's hard to test. Please let me know.

It seems to have been fixed. (iPad Air 2, iPad OS 13.4.1)

Been doing some heavy-duty testing over the past couple of days and I can't seem to find any instances of the viewer box jumping anymore. Looks like the issue that's been plaguing me for several months has finally been slain. Thanks!!!!!!


However, I've found a related but less significant bug: closing one viewer window and opening another fixes the newly opened one in place and I can't seem to move it.

Crossposting this from the wiki: GUYTU6J has discovered that there are several rules that are currently stored on the wiki as ruletables but which can be converted into either isotropic or MAP LifeViewer aliases.

I'm 99% sure that all of these are already converted into aliases.

LifeViewer will favour built-in aliases over Rule namespace lookup. The list of alias definitions can be seen in Help->Aliases.
You can tell whether LifeViewer is using a Rule namespace definition in Help->Info->Pattern. If so there will be a Type of @TABLE or @TREE.

Appears to be working correctly now.

Oh cool! (no)

Code: Select all

#C [[ AUTOSTART TRACK 1 1 ]]
x = 7, y = 3, rule = MAPAQydAEBuUCZLAJY2A6CIwgQM+NAFAYOpALiBAoIQtJiCcQOEQA4bAIImeyAAEQCggFgc0FCSABiRAgAUgEoBgQ
2o2b3o$3b03b$b05b!

It appears that track breaks autofit. (also breaks fit pattern to display) It isn't even the track, turning track off first gives the same results. Starting autofit before track (via reset or smth else) is fine, though.
Also, track jumps erratically.

Code: Select all

#C [[ AUTOSTART TRACK 1/4 1/4 STEP 10 ]]
x = 3, y = 3, rule = B3/S23

Can you commit these to the rule list on catagolue gitlab first?

[rowett]

It appears that track breaks autofit.

TRACK's assumption is that the pattern being tracked is constant size (like a glider or other spaceship). So AutoFit is using the original pattern size. I'll take a look to see how easy it will be to remove that assumption.

sansdomino is a rulespace for all b2-a rules but committed

Build 527 is now live on the Forums and LifeWiki

Please note: you will need to refresh your browser to use the new build (Ctrl-F5 on Chrome)

Enhancements since the last released build:

• UI
  • hotkey Ctrl+F will Fit Selection to display
  • hotkey Ctrl+M for Middle (center pattern on display but don't change Zoom)
  • hotkey Ctrl+C while Help displayed will copy topic to clipboard
• Script commands
  • added [[ PASTEDELTA X Y ]] script command
    • sets incremental position delta for subsequent [[ PASTET EVERY ]] commands
  • annotations now support specifying the zoom range at which they will be visible
    • [[ LABEL X Y ZOOM (MAXZOOM) (FIXED) "string" ]]
    • [[ ARROW X1 Y1 X2 Y2 ZOOM (MAXZOOM) (FIXED) ]]
    • [[ POLYLINE X1 Y1 X2 Y2 .. ZOOM (MAXZOOM) (FIXED) ]]
    • [[ POLYFILL X1 Y1 X2 Y2 .. ZOOM (MAXZOOM) (FIXED) ]]
    • if MAXZOOM is specified then the annotation will be visible from ZOOM to MAXZOOM
    • if MAXZOOM is not specified then the annotation will be visible from ZOOM / 4 to ZOOM * 4 (the current default)
    • negative zoom value -N mean a zoom of 1/N so ZOOM -4 is the same as ZOOM 1/4 or ZOOM 0.25
  • added [[ REVERSESTART ]] script command
    • sets initiable playback direction to Reverse for reversible rules
    • ignored for other rules
    • reverse playback is also set on Hard Reset
• Display
  • Margolus gridlines now alternate by default
  • display message if Identify reaches maximum period
• Rules
  • added support for Cross, Saltire and Star neighbourhoods for LTL and HROT rules
    • specify with N+ for Cross, NX for Saltire and N* for Star
• General
  • Randomize now supports alternating rules
  • added more aliases

Fixes since the last released build:

• fix window position on mobile Safari
• fix second popup move on mobile Safari
• fix Load Pattern
• fixed Theme button position
• fixed Help->Info->Identify having info when no identification happened
• fixed an issue with Nudge and Selection direction
• fixed an issue with Copy to External Clipboard and Selection direction
• fixed [R]History 2-state paste
• fixed [[ RLE ]] with multi-line patterns
• fixed support for reversible alternating Margolus rules
• fixed a couple of aliases
• fixed PCA Invert Selection
• fixed PCA initial population count
• change PCA births and deaths calculation to use subcells
• fixed Change Rule incorrectly enforcing VIEWONLY
• hide Random 2-state button for PCA patterns
• check Mod values using more than 1 sample
• remove Identify Close button for empty patterns
• fixed inconsistency on PCA Identify
• change Speed values to canonical form
• fix Margolus Still Life detection
• grey out Step Back button when disabled or at Gen 0 with non-reversible rule
• PCA state 0 drawing should draw background colour
• switched Alive, Births and Deaths label and value so the value is visible when reversible rules are loaded
• disable reverse playback for alternating Margolus rules
• fixed an issue calculating rotor and stator missing the final generation
• allow custom colours for RuleTable states
• fix Mod for PCA
• fixed Margolus bounding box on alternate generations
• fixed selection box position with #CXRLE Pos
• fixed STEP in Waypoints
• bounded grids were clipping Margolus patterns
• check FlipX and FlipY before FlipXY in Mod detection
• remove period 1 from simplified Speed
• better error handling for invalid LtL/HROT rules
• fix Evolve Selection initial position and handling life ending

The updated hotkey map detailing the LifeViewer keyboard controls is here.
