Hello, when trying to insert a node using node.insert_before, and if <current> is equal to <head> (to make <new> the new head), the following error is generated: Attempt to node.insert_before() a non-existing node The node I want to insert exists, as well as <head> and <current>. If I manually special-case the code, just like Heiko Oberdiek does in his luacolor package, everything works perfectly. Is this a bug? A feature? I'm using the svn trunk from last friday. Jonathan

there have been problems with the insertion helpers, so maybe something surfaced again; anyhow, the latest version has other problems so best wait till there is an update, since one never know what interferes. (I use a previous version).

It's an oversight, I will fix it in the next release.

Hans means TRUNK has problems. 0.25.3 was fine. Best wishes, Taco

Great! Just in case, I have prepared the following example (I do not claim that it is the shortest possible ;-): %&luatex \directlua0{\unexpanded{ head = node.new(0) before = node.new(0) after = node.new(0) head = node.insert_after(head, head, after) head = node.insert_before(head, head, before) }} \bye Jonathan
