As I said, I don't > really know how to write a module... comments are very welcome. Honestly, it doesn’t work, but that’s a minor flaw! If you want to use buffers with indirection you have to take care of the argument delimiters. \grabbufferdata is excellent for that. I did some rewriting: stray globals and rough namespacing, mostly. On the practice of calling TeX macros from Lua, the cld manual can give you a boost: http://www.pragma-ade.com/general/manuals/cld-mkiv.pdf This explains how to properly use the context.*() namespace instead of tex.print and the likes. I could not figure out how exactly the section block thingy is supposed to work. It does not create the \startframe macro at all -- is this something custom? I infer it’s about the slide title so I have \startframe call \section but that should be taken as a placeholder at most. In my own slide module I use \{start,stop}section with the option placehead=no and rely on the page header to display the slide title (i.e. current section running head). That was the laziest way I could imagine :P Some remarks: - you should rename simplesteps.mkiv to t-simplesteps.mkiv, indicating that it is a thirdparty module - if you plan on expanding the code you eventually will come to love this bit: http://wiki.contextgarden.net/System_Macros - Context has a namespacing system which you might consider switching to in the long term: http://tex.stackexchange.com/q/58654 but it’s arguably an advanced method - maybe switch to mkvi as named parameters make rewriting macros a breeze > Is it ok if I send a PDF sample to the list?

So, I am doing like this right now: (numbers like 2-3 or 2- don't work yet) === START code snip === \startbuffer[simplesteps] \startitemize \item First item \uncover[2,3,4]{\item Second item} \uncover[3,4]{\item Second item} \uncover[4]{\item Second item} \stopitemize \stopbuffer \simplestepsplaybuffer === STOP code snip === The "simplestepsplaybuffer" macro simply calls the simplesteps.playbuffer() lua function. This function plays the buffer and determines if it has to be played again or not. If it does, then it tex.print('\simplestepsplaybuffer'). The macros "uncover" determine how far the specification is from being played. If it is being played now, then show. If it is played "next", then show in gray. And so on. > I infer it’s about the slide title > so I have \startframe call \section but that should be taken as a > placeholder at most.

The \grabbufferdata command reads only all text until the end command (e.g. \thisistheend) but the beginning command for the buffer (e.g. thisisthestart) has to be defined by the user.
