Thread for your script-related questions

[dvgrn]

I know of a script that turns patterns to apgcodes, but is there a script that turns apgcodes to patterns?

This script by Ilmari Karonen seems to fit the bill. I haven't tested it, but the comments show a good level of awareness of the different apgcode variants.

Tangential note: I knew the name "Ilmari Karonen" was familiar, but I had no idea why. Turns out one of my first blog posts was about a question he asked on the comp.theory.cell-automata newsgroup, which was more or less the public predecessor of the conwaylife.com forums.

I didn't even remember that I had started that blog that early (first post in late 2004). Memories of that time are very hazy -- had electricity even been invented back then, let alone the Internet? It's clear from the pattern format that this was before LifeViewer's time, at least.

I can't even load in a loafer.

Why not, exactly? Please try being more specific in bug reports -- it seems silly to have to go through several cycles of posts to painfully extract the relevant information from people.

I saved the script to Golly's Scripts/Python directory, entered "xq7_3nw17862z6952", and ended up with a downward-traveling loafer, as expected.

Wait, sorry. I accidentally pasted it into a filename which might've removed some important characters.
Edit: I pasted it in properly this time and it works. Sorry for the confusion.

Is lifelib capable of analyzing methuselahs, i.e. given a pattern RLE, can any function output its lifespan, bounding box, MCPS, final population, etc?

How do I compile and run the Java QuasiTiler from https://sourceforge.net/projects/quasitiler/? I have installed Java —

Code: Select all

java version "1.8.0_281"
Java(TM) SE Runtime Environment (build 1.8.0_281-b09)
Java HotSpot(TM) Client VM (build 25.281-b09, mixed mode, sharing)

— but my command prompt doesn't recognize "javac".

How to make viewers on other websites (html5?)

[dvgrn]

How to make viewers on other websites (html5?)

Meaning, you want to set up LifeViewer to work outside of the context of the forums or LifeWiki?

Here are some sample HTML files that do basically that. You can run those pages offline, at the expense of probably using an older version of LifeViewer. (I haven't bothered to update the checked-in version of lv-plugin.js past Build 521, whereas the current version is something like 597.)

Instead of the line '<script src="lv-plugin.js"></script>', you could point the browser to some other location, like

Code: Select all

<script src="https://www.conwaylife.com/forums/styles/prosilver/template/lv-plugin.js"></script>

If you do that, then you'll always be working with the latest version of LifeViewer -- as long as conwaylife.com isn't down and you have a working Internet connection.

Otherwise, you just need to follow the exact HTML structure given in the samples, and LifeViewer will see it and use it:

Code: Select all

<div class="viewer">
	<a href="" onclick="updateViewer(this); return false;">View Standalone</a><br>
	<textarea rows=4 cols=75>
#C put RLE here
#C [[ "with LifeViewer waypoint script commands" ]] if you want them
x = 3, y = 3, rule = B3/S23
3o$o$bo!
	</textarea>
	<br>
	<canvas width="1024" height="512"></canvas>
</div>

Canvas size, textarea height, link text, etc., can be adjusted as needed. LifeViewer is mainly looking for the div with a class of "viewer", and inside that, a textarea containing the RLE, and a canvas.

There's probably something subtle I've forgotten about the "View Standalone" link at the top, but maybe someone else can explain that.

What about a rule generator for alternating rules? Like viewtopic.php?f=11&t=719&start=75#p72993 but generate the rule table but not only running a pattern.

Why do the parameters B34/S1567/o3n1v/l108 in gfind mysteriously get stuck so quickly?

[Sokwe]

Why do the parameters B34/S1567/o3n1v/l108 in gfind mysteriously get stuck so quickly?

It does seem to be getting stuck at depth 73 and can't complete the depth-first step. I also tried giving it a large queue size and it still appears to get stuck in the breadth-first step.

Interestingly, I ran it with Paul Tooke's modified gfind (compiled with PATCH04 commented out to allow for searches above logical width 14) and it finds a ship at depth 73:

Code: Select all

x = 36, y = 22, rule = B34/S1567

It then completes the depth-first step normally. Without actually looking at any code, I would guess the problem is in success(), which should print a complete spaceship detected by terminal() (one could check if it gets stuck after terminal() returns true). Perhaps an older version of gfind will work (such as v4.6, on which Paul's modification is based). Then one could look at the changes between versions to get an idea of what's causing the problem.

I can't compile those now, so you try: B35/S16/o3n1u/l108.

EDIT: Found using ikpx2. The search in this rule is very memory-intensive for some reason.

Is there a Lua script that converts

bo$2bo$3o!

into

Code: Select all

I don't know of one. But I discovered recently that I had forgotten all the Golly-related Lua that I used to know, so apparently I need some practice.

I checked in this script for you -- pat-to-ascii.lua:

Code: Select all

-- pat-to-ascii.lua
-- select a pattern in Golly, run this script,
--   and a plaintext ASCII format version of
--   the pattern will be copied to the clipboard
--
-- For a variant producing Life Lexicon format, see also
--   http://conwaylife.com/forums/viewtopic.php?p=64427#p64427

local g = golly()
r = g.getselrect()
s=""
for y = 0, r[4] do
  for x = 0, r[3] do
    if g.getcell(x+r[1], y + r[2]) == 1 then
      s = s.."*"
    else
      s = s.."."
    end
  end
  s = s.."\n"
end

g.setclipstr(s)

Changes to the above to make it produce the RLE format that you're asking for, are absolutely completely trivial, to the point where anyone can do it even if they don't know anything about programming. It currently works on a selection in Golly and writes the output to the clipboard -- so it would take just a little bit more fiddling to start with a standard RLE pattern in the clipboard and end with a Catagolue-style RLE pattern in the clipboard.

If you can't see how, just ask more script-related questions here until you can see how.

I realized that a completely different thing called Java(TM) SE Development Toolkit 16 (64-bit) is required to use command "javac". However, the existence of jdk prevents me from running other .jar files like SeedsOfDestruction.v0-5.jar by simply clicking on it. Why is there such a conflict?
