Pattern viewer for forum threads

[dvgrn]

Chris Rowett and Nathaniel Johnston have been working on adapting Chris' HTML5 LifeViewer to allow inline previews of quoted patterns in conwaylife.com forum messages. The current Build 129 is ready for general use. Post questions, comments, bug reports, and feature requests in this thread.

Here's a sample use of the viewer:

Code: Select all

Just wrap RLE or other standard pattern formats in [ viewer]...[/viewer] tags instead of [ code]...[/code].

Click on the pattern image to get a full-sized viewer. Once you've clicked, you can control the viewer with the mouse or with keyboard shortcuts. Press 'H' for the help pages, which list the available options. Press 'C' to cycle through a set of predefined color themes, for example.

Script commands are also summarized in the Help pages. These can be added to the comments section of any pattern to change different attributes of the viewer. Here are the script commands used for the above pattern:

[[ THUMBNAIL AUTOSTART ZOOM 5 HEIGHT 480 LOOP 1940 ]]

With different settings the viewer can produce very different displays:

Code: Select all

Whoa, thanks for the fast and thorough explanation and thanks for using the soup I found! I was on my smartphone so I couldn't see the help window. Despite all that, I was able to control and understand most of it. Great app and tutorial. Is it possible to use it as some sort of library so that one could embed it in other web pages?

[dvgrn]

Is it possible to use it as some sort of library so that one could embed it in other web pages?

I don't see why that wouldn't work. The main thing you need is the Javascript plugin file, lv-plugin.js, and that's pretty nicely packaged up already. One way to start would be to save some simple message thread as a standalone Web page and boil down the HTML to get a minimal template.

But very likely Chris can give better and more specific advice than that...!

[rowett]

Is it possible to use it as some sort of library so that one could embed it in other web pages?

But very likely Chris can give better and more specific advice than that...!

Here are the instructions for embedding LifeViewer into a web page.

• Include the LifeViewer Javascript plugin "lv-plugin.js". You will need to change the <script> tag to point to where you have installed it.
• Create a <meta> tag with a name of "LifeViewer" in your webpage <head> section

  Code: Select all

  <html>
      <head>
          <meta name="LifeViewer" content="viewer textarea 30 hide limit">
          <script src="js/lv-plugin.js"></script>
          ...
      </head>
      ...
  </html>

• The content part of the <meta> tag should contain a list of two mandatory words in a specific order and then up to three optional words in any order:
  • "viewer" - the class name of the <div> that wraps the element containing the pattern definition and the <canvas> element
  • "textarea" - the name of the element containing the pattern definition (in one of the supported pattern formats, typically RLE)
  • (optional) "30" - if specified then sets the height in pixels of the element containing the pattern definition
  • (optional) "hide" - if specified then hide the <canvas> element if the browser doesn't support LifeViewer
  • (optional) "limit" - if specified then limit the width of the LifeViewer to the width of the element containing the pattern

The example below shows how you embed LifeViewer in your page with the glider pattern. In this case without limiting the LifeViewer width to the <textarea>, without limiting the <textarea> height, but still hiding the LifeViewer if the browser doesn't support it (since we specified "hide").

Code: Select all

<html>
    <head>
        <meta name="LifeViewer" content="viewer textarea hide">
        <script src="js/lv-plugin.js"></script>
    </head>
    <body>
        <div class="viewer"><textarea>bo$2bo$3o!</textarea><br><canvas width="480" height="480"></canvas></div>
    </body>
</html>

If you omit the <meta> tag then it defaults to the conwaylife.com settings:

Code: Select all

<meta name="LifeViewer" content="rle code 37 hide limit">

You can put multiple LifeViewers on a single page. Each time you want one just specify an enclosing <div> containing both the <textarea> with the pattern and a <canvas>.

Code: Select all

<div class="viewer">
    <textarea>bo$2bo$3!</textarea>
    <canvas width="480" height="480"></canvas>
</div>

Just wanted to pipe in and say this is incredibly cool! Thank you all for your work on it! I can't wait to go play with it.

Also, is there an unobtrusive place on the forums that I should go to learn to use it and play around with it? Or is it ready for incorporation everywhere on the forums? I just haven't seen it in use yet in any of the threads I visit yet; I wouldn't want to disrupt or risk breaking anything or bogging anything down.

[dvgrn]

Don't get your hopes up too far, though. For multistate rules like the Shapeloop variants you've been working with recently, you can display images of the patterns you're posting, but you can't animate them. The viewer doesn't handle Golly's rule table format, so it can only actually simulate regular Bmmm/Snnn Life-like rules.

-- But I definitely agree: it's great to be able to see pattern previews, just to know if it's something you want to copy out and investigate further. A lot of times the viewer seems to be all I need, so it's nice that more people are starting to use it.

[Tezcatlipoca]

For multistate rules like the Shapeloop variants you've been working with recently, you can display images of the patterns you're posting, but you can't animate them.

Haha, yeah I'd be lying if I said I wasn't hoping I'd get the chance to push things even further with functioning Shapeloop variations in HTML5, but I wasn't betting on the Ruleloader rulesets to be implemented. The fact you can display an image will be incredibly helpful, though, getting a visual sense for things, comparing them visually. I was investigating just over the past days into different ways to take screens from Golly with less user input, effort and trouble to use myself, so this is still a big deal to even me with my currently narrow interest.

So we are good to go ahead and post with this all over the forums then?

[rowett]

Yes, please do!

[Gustavo6046]

I wish we could draw cells, control the generations, and it had a grid, so it could normally function like a replacement for the old, deprecated Java applet. And the best: It would be soo simple to do that adaptation and to use it! Love it so much! XD Now school delay things a little, but still can be safely one enthusiast.

[Gustavo6046]

Don't forget to leave a answer. Real life sounds pretty weird!

[gameoflifeboy]

I think that the pattern viewer should definitely have a step size feature, like

Code: Select all

#C [[ STEP n ]]

where n is the number of generations to skip. Without it, many patterns run too slowly even at sixty GPS.

Yeah, good idea. Also one bigger supported amount of GPS would be preferred. Weld this to my latest idea(s) of improvement and we get the perfect "mini-Golly"! Wait, this time don't put a Kok galaxy in the logo, put a Doppler star instead!

[wildmyron]

Thank you to all involved for integrating the HTML5 rle viewer.

I have a request related to performance on older hardware for situations where many viewers are present in one thread page. Is it possible to have a user profile setting to disable the AUTOSTART feature? Currently I find myself going through a thread and pausing the patterns I'm not interested in so that the one I am interested in will run at a reasonable speed.

Similarly or alternatively the ability to have THUMBNAIL be a default would help performance as full size viewers seem to run much slower.

[rowett]

I wish we could draw cells

Noted.

... control the generations

In what way?

... and it had a grid

It does. Use hotkey "X" to switch the grid on and off, and the [[ GRID ]] script command to have it initially on.

Code: Select all

#C [[ GRID ]]
x = 22, y = 7, rule = b3/s23

I'll work with Nathaniel to see if it's possible to integrate the Viewer with settings on the forum. If not I could probably have the Viewer manage its own preferences.
In the next build (not yet published) I've added hotkey "Z" which will pause all other Viewers.

This could certainly be added. Please could you help me understand specific use cases where this would be helpful. For example: Would you want to run a pattern at STEP=10 for a number of generations and then return to STEP=1?

And just so I've stated it: LifeViewer is not Golly

edit the pattern in the viewer...

The ability to rewind and get faster.

nice!

Many thanks for your suggestions,
Chris

You're welcome, it is only my daily work.

And just so I've stated it: LifeViewer is not Golly

[rowett]

The ability to rewind and get faster.

Some of that exists already. The controls at the bottom of the Viewer do as follows (from left to right):

• Gen - click to toggle display of rule, elapsed time, population, births and deaths (hotkey "G")
• 20gps - slide to set playback speed (hotkeys "-" and "+")
• Reset - reset to generation 0, if already reset then also reset camera (hotkey "R")
• Pause - pause playback if playing, otherwise step to next generation (hotkey SPACE)
• Play - start or continue playback (hotkey ENTER)
• Menu - toggle display of the navigation menu to control the camera (hotkey "M")

There are many other controls that are documented in the built-in help which can be viewed with hotkey "H".

[Scorbie]

Just a minor thing. I'm kinda confused by the arrow keys since LifeViewer's movement is the opposite of golly's. Is it possible to change them?

Also, how could I get lv-plugin.js? (Just curious)

Oh and real thanks to your work

I knew we'd never get to all the features of golly, but I realized that many patterns, especially soups from the "Soup Search Results" thread took thousands of generations to stabilize, such as this one, which takes 30 seconds at 60 GPS.

Yes, I hadn't realised it was different than Golly. I'll change it in the next build.

Also, how could I get lv-plugin.js? (Just curious)

Just copy it from the forum:
styles/prosilver/template/lv-plugin.js

Also see this post for how to use on your own site:
viewtopic.php?f=3&t=1622#p17014

My pleasure.

OK it will be in the next build.

Thanks for using my "racetrack and ortho-beacon" soup to demonstrate your update!

Very nice additions. When I first saw LifeViewer in 2013, I had hopes for it -- and now those are coming true!

Why have my posts to this forum been changed by adding 'SHOW IN VIEWER' to the pattern examples? This option provides no useful information and is confusing when the states are colored incorrectly. The decision to display a pattern should be made by the post's author and not automatically provided by the website code.
