You can press one of the following keys to get integer zooms:
  • 1 - zoom 1x
  • 2 - zoom 2x
  • 4 - zoom 4x
  • 8 - zoom 8x
  • 6 - zoom 16x
  • 3 - zoom 32x
  • shift 2 - zoom -2x
  • shift 4 - zoom -4x
  • shift 8 - zoom -8x
  • shift 6 - zoom -6x
These keys also control zoom:
  • [ - zoom out
  • ] - zoom in
  • shift [ - halve zoom
  • shift ] - double zoom
  • f - fit pattern
  • F - toggle autofit
Alternatively if you want to post a pattern and have it open at a specific zoom use the ZOOM script keyword.
#C [[ ZOOM 20 ]] want exactly x20 zoom when pattern opens
x = 3, y = 3, rule = Life

Build 182 is now live on conwaylife.com

Please note: you will need to refresh your browser to use the new build

For the examples below click on a thumbnail to see full size. Hotkey "n" toggles between thumbnail and full size.

Enhancements since the last released build:
  • added support for bounded grids
    • Plane, Tube/Torus, Cross-surface, Klein-bottle and Sphere
    Code: Select all
    #C [[ THUMBNAIL ]]

Fixes since the last released build:
  • multiple [[ LOOP ]] or [[ STOP ]] script commands are now flagged as errors
  • bounding box calculation occasionally created a box too high
  • custom colours DEAD and DEADRAMP were switched
  • help information for the tile count was only updating every even generation
  • patterns of any size can now be deleted when they hit the large grid boundary
  • pattern reader fails fast on patterns that are too big

Christ, this just keeps getting better and better! No criticism or bug reports from me this time around (those'll probably come later, no worries), just a sincere thank-you for taking the time to make the forum so much more engaging and easier to use.

It seems that you can't rotate the view (the angle slider in the menu that comes up) on hexagonal grids. The slider moves and the graphics stay put.

The Hex display does not support rotation. The angle slider should not appear. Thanks for reporting!

EDIT: This is fixed and will be in the next released build. See here for the test case.

Noticed a bug in this post. After the top right pattern dies out, two bits seem to continually oscillate back and forth:

Code: Select all
x = 38, y = 37, rule = B3/S23

Wolfram rule numbers must be even. This has been fixed and will be in the next build. Thanks for reporting!

LifeViewer support backslash escaping?
for example:
#C [[ TITLE "\\" ]]
#C [[ "\\" ]]
#N R-pentomino
#C A methuselah with lifespan 1103.
#C http://www.conwaylife.com/wiki/index.php?title=R-pentomino
x = 3, y = 3, rule = B3/S23

No, but I'm not sure it's needed. LifeViewer doesn't treat backslash as a special character.
#C [[ TITLE "\" ]]
#C [[ "\" ]]
#N R-pentomino

#C http://www.conwaylife.com/wiki/index.php?title=R-pentomino

Added B0 emulation support for totalistic rules with Hex or Von Neumann neighbourhoods. This will be in the next released build.

#CXRLE Pos=0,0 Gen=0
x = 5, y = 3, rule = B02/S0V

I can fix this but I don't know what you're trying to achieve by nesting a < code > block inside a < viewer>, please let me know.

Request: close shortcut key and grab focus on start.

Postby JohanB » June 12th, 2016, 11:33 pm

1. Can I have a shortcut key to close the viewer?

I find myself doing the following:
Read a post, click on "show in viewer"
play around with the pattern (using the keyboard).
continue with the rest of the thread... Oh wait viewer is in the way. Press [esc].
I then have to aim for the X with the mouse, whereas 95% of my time I'm using the keyboard.

Can you assign a key to close the viewer. [esc] would be ideal but you've already used that for pause,
seeing as there are many other keys also assigned to pause, I'd still like to campaign for [esc] = close.
If not some other key on the edge of the keyboard [`] or [z].

2. Is it not possible to have the viewer grab the keyboard focus when it starts?

In all other respects LifeViewer is a joy to work with. I esp like the scroll edit controls, very nice piece of UI.

Yes, completely agree with the need for a key to close the standalone (popup) LifeViewer.

JohanB wrote:[esc] would be ideal but you've already used that for pause,

I agree [esc] feels like the natural choice for close. The reason it's used for pause is because Golly does and where possible I try to duplicate the shortcut keys. Of course Golly (and the inline LifeViewer) have no ability or need to close.

The options are:
  1. [esc] closes the standalone LifeViewer but pauses playback on the inline LifeViewers
  2. [esc] closes the standalone LifeViewer and does nothing on the inline LifeViewers
  3. we pick a different shortcut key
Feel free to vote!

JohanB wrote:2. Is it not possible to have the viewer grab the keyboard focus when it starts?

It is possible but I found it annoying especially since the focus would include the mouse.
  • If I press [space] did I want to toggle playback on the LifeViewer or have the browser page down?
  • If there are multiple inline LifeViewers on a page which do I want to interact with?
  • If I scroll the mouse wheel do I want to scroll the browser page or zoom the LifeViewer display?
To remove these types of ambiguities you have to explicitly "Click to control" the LifeViewer (and it automatically loses focus as the mouse moves off it).

Great, many thanks for the feedback.

Build 188 is now live on conwaylife.com

Please note: you will need to refresh your browser to use the new build

Enhancements since the last released build:
  • added B0 emulation support for totalistic rules with Hex or Von Neumann neighbourhoods - test
  • if the STEP size is too large to allow frequent updates then it will by dynamically reduced to keep the UI responsive
Fixes since the last released build:
  • fixed a visual glitch caused by a previous optimization - test
  • [[ TITLE ]] string was ignoring text after last variable substitution - test
  • & symbols in script strings were being converted to html friendly versions - test
  • snapshots were not working with patterns containing no live cells
  • Wolfram rule number must be even - test
  • when all cells died the STEP size was ignored
  • partial fix for embedding <code> tags inside <viewer> tags
Comments, feedback, suggestions and bug reports welcome!
