[luatex] Turning a string into a list of nodes.

[Patrick Gundlach]

Hi Paul,

> Patrick, is it on purpose you don't set "n.prev = last"? Is it useless or are you sure you'll simply never manipulate those node lists?

I omitted node.slide() in my pseudo code :) I use node.slide() just before node.kerning() to set the prev pointer. Maybe one day I'll clean up my code and use .prev = ... instead of node.slide().
