Re: Proposal: Recursive RLE

But next time you do something like this, please consider the option of allowing old-style parameters where practical. Rest assured I do try to ensure that changes to the scripting API are backward compatible. I made an exception in the case of setcursor/getcursor because it became clear when I add...

Re: Golly scripts

p30 printer: update This version comments out the setcursor() call, which fails on recent versions of Golly. It will also allow you to recover the uncompressed version of the compressed output script: simply run the output script at the command line instead of in Golly & the script will be printed ...

Re: Proposal: Recursive RLE

Sorry about this slight thread hijack, igblan. I hope you don't mind. I guess one big advantage your scheme has over a Python script is that it's not dependant on a particular Life program, and a standalone translator could convert it to the original RLE format, or other formats, if required. And Py...

Re: Proposal: Recursive RLE

Interesting! I'd love to see some examples. And your Python code. :) What isn't trivial is a general-purpose pattern-to-RLE converter. It is expected that patterns generated with software assistance, like the MRM or the Caterpillar, could generate fairly efficient RLE strings. Yes, the general conve...

I guess I should upgrade from Golly 1.2, then. :)

Actually, I think it's time for me to get a whole new Linux distro. This one (Mepis) came from a CD-ROM in a library book, about 5 years ago (and I couldn't upgrade it, as I had a Windows-only modem :( ).
