Megacell problem

[wwei23]

Golly says that the rule is invalid. Now I'm going to have to spend HOURS fixing it before I can run the Demenoid.

Golly says that the rule is invalid. Now I'm going to have to spend HOURS fixing it before I can run the Demenoid.

The other people reading your posts can't see what you're seeing, unless you include some kind of explanation. If this is meant to be a bug report (about Calcyman's megacell? or some specifc .mc metacell file? or what?) it will need more detail. What exactly did you do, in which version of Golly, on what OS, just before Golly said that the rule is invalid?

[wwei23]

Windows 10, Golly 2.8, Lifewiki megacell, and I tried to paste it in.

Windows 10, Golly 2.8, Lifewiki megacell, and I tried to paste it in.

Specifically, This RLE from the LifeWiki? It's just "rule = B3/S23", so I'm not seeing any "invalid rule" error. Try it again, maybe? Sometimes it takes a while for those long RLE pages to load -- though that should just give you a truncated pattern, not an invalid-rule error.

Anyway, that single-cell pattern is not too useful on its own. Much better to use the universal megafier script to build megapatterns for you.

-- But what would that have to do with running the Demonoid? A Demonoid made of megacells is definitely not an experiment worth trying... but I suspect there's something else that I still don't understand.

[wwei23]

No, I mean the Megacell format.

[dvgrn]

No, I mean the Megacell format.

Ah, got it. "Megacell" (a pattern, a specific type of unit cell) means something different from "macrocell" (a file format intended for Golly Hashlife patterns).

The old Demonoid spaceship is indeed on the LifeWiki in macrocell format. So you are having trouble with this link, then? If you include actual links like this, it's much easier to understand the problem.

I just tried copying and pasting the text from that link, and the Demonoid is loaded correctly on my system and works with no problem. It's really important to wait until the page loads completely before you try to copy the text out of it. Unlike truncated RLE, truncated macrocell-format files don't even give you the top part of the pattern.

Try again, maybe? Make sure the last line of the text that you copy is "17 0 14 0 5851". And quote the exact text of the error you see, if you still see an error.

[wwei23]

I tried and it said that it could not load the pattern probably due to an unknown rule.

[dvgrn]

I tried and it said that it could not load the pattern probably due to an unknown rule.

What exactly did you try?

1) Go to this link,
2) wait 30 seconds,
3) confirm that the last line of text on the page is "17 0 14 0 5851",
4) hit Ctrl+A, then Ctrl+C,
5) open Golly 3.0b1,
6) type Ctrl+Shift+O (or File > Open Clipboard).

It's hard to tell what is happening exactly, but it sounds as if you're trying to open a damaged copy of the macrocell format. The above steps should give you a clean copy.

By the way, I called .mc files "metacell format" in my post yesterday. That was a typo -- should have been "macrocell format" -- I've fixed it now. A metacell, like a megacell, is a unit-cell pattern, where macrocell format is what you're copying out of the LifeWiki. Yes, it's very confusing...!

[wwei23]

I have 2.8.

[dvgrn]

I have 2.8.

Macrocell format support in Golly hasn't changed for a very long time, so that shouldn't matter.

Can you open other .mc files? For example, try Patterns/Hashlife/logarithmic-width.mc. That has a similar .mc-format header, but no specific #R B3/S23 rule line.

If that works, try using a text editor to remove #R B3/S23 from the text you're trying to paste in. I don't see why that would make any difference, but it seems as if your copy/paste operation isn't copying the text accurately. You might also try saving the text from the linked page as a file on your computer, then using File > Open and see if Golly will open it that way.

Maybe the problem will become obvious if you paste the beginning and end of the macrocell file text here, in a code block, like this:

Unfortunately the full length of the file is too long for a post -- so don't try copying the above, it's not the whole pattern...!

[wwei23]

I get that it has to be spaced correctly, it just takes a really long time.

[dvgrn]

I get that it has to be spaced correctly, it just takes a really long time.

I don't know what "has to be spaced correctly" means in this context.

I also don't know what would take a really long time.

?

Are you editing the macrocell file by hand to add or subtract spaces, or something like that? That would take a really long time! But no editing should be necessary. The text in the link should work if you copy and paste it directly into Golly 2.8, with no changes -- as long as you're really copying all the text in one chunk.

So, have you done all six steps that I listed, and it still doesn't work? It's not clear.

[wwei23]

Yes!

[dvgrn]

Yes!

I suspect you mean

So, have you done all six steps that I listed, and it still doesn't work? It's not clear.

Yes!

-- so that leaves the other two questions. I'll try to ask them more clearly:

1) What does "has to be spaced correctly" mean?
2) What would take a really long time?

The macrocell file really isn't human-editable. Here's a copy of the same file, in several formats, in case that's any use:

Demonoid.rle

0hd Demonoid in compressed macrocell format

These all just open on any of the versions of Golly on my laptop, with no rule-related errors.

[wwei23]

Great! The files actually work!☺☻

[dvgrn]

Great! The files actually work!☺☻

Good! Now, just so we don't leave a bug un-solved, could you copy the first and last parts of the text from the LifeWiki link that you were having so much trouble with, and put them into a post in a [code] box so that I can see what was going wrong?

I have the feeling it will be a familiar problem when I see it, but right now I can't guess what the problem was.

{macrocell file with newline characters converted to spaces}

Very interesting! In Google Chrome and most other browsers, the newline characters are displayed correctly, and you can copy the text right out of the browser window without any trouble.

I just checked Internet Explorer 11, and for reasons known only to Microsoft it tries to render the macrocell file as HTML text. That means it throws away all the newlines and replaces them with spaces -- what a mess! Reminds me of why I avoid using Internet Explorer whenever I possibly can.

If you're stuck with Internet Explorer, though, there are perfectly good workarounds. For example, go back to this same link, right-click and choose "View Source". If you copy that text it should paste into Golly with no problem.

(Seems to me there should be a way to right-click on the above link and save the file directly. Google Chrome has a perfectly workable "Save link as..." option, but silly Internet Explorer has its "Save target as..." option greyed out for whatever reason.)
