The script below allows you from Golly to launch LifeViewer in your default browser with the current Golly pattern. This is now part of the Golly distribution and will appear in the next release.

Works for me! The only thing that would have made it a little more user-friendly is if showinviewer.lua could have created the "lifeviewer" subfolder, if it didn't already exist. That would allow the full path to be copied out of the pop-up HTML, and right-click > Save As... could put lv-plugin.js right where it's supposed to go immediately.

Having Golly patterns openable in LifeViewer means that it now suddenly makes a lot of sense to include waypoint scripting comments, labels, points of interest, default zoom and pan settings, etc., as part of comments in patterns checked in to Golly. Labels in particular seem like they could be really useful, for example to help people understand complex patterns at a high level.

In case anyone wants a random sample to try out: open the following pattern in Golly (by saving and opening it, or via Copy and Ctrl+Shift+O to preserve the comments). It will look ... relatively boring. Then run showinviewer.lua, and the labels and animation will show up.

Good idea! This has been implemented and I've updated the first post with the the new version.

broken for me

It was an issue specific to Firefox. I've fixed it and posted a new version of the script in the first post. Thanks for reporting!

The script in the first post has been updated to handle spaces in folder names.

No because Golly doesn't support NB neighborhood yet.
