[lltx] luatexbase and module version

Fri May 10 18:40:18 CEST 2013

Hi,

luatexbase-modutils provides means to test if and what version of a
module is loaded.  I want to test if a certain version of package
luatexbase-attr is loaded, but the attached code returns nil.

Alternatively, I could check if a particular feature foo is present via

  if luatexbase.foo then

instead, but I wonder why applying the interface provided in
luatexbase-modutils to package luatexbase shouldn't work.

BTW, as you can see from the log file, package luatexbase-attr from
luatexbase v0.6 identifies itself as 2011/05/24 v0.4.  I know, there
have indeed been recent changes to luatexbase-attr.  Is that package
version and date intentional?

Best regards,
Stephan Hennig
