I should have looked if there is a “delayed” alternative for externalfigure as well, but I also take Hans’s warning to heart that all of this is non-trivial.

Hi Thomas, Not sure whether it helps or not, but in regards to combinations and Lua I have had some challenges as well, but Hans' and Wolfgangs' solution with externalfigures works fine for me now: https://mailman.ntg.nl/pipermail/ntg-context/2021/103822.html https://mailman.ntg.nl/pipermail/ntg-context/2021/103827.html Adam On Mon, Mar 28, 2022 at 2:42 PM Thomas A.

[NTG-context] Xml - Lua - context
And here comes question 2, a very basic one: on A4 landscape pages, I want to place two images next to each other (like the spread pages of a book). What would be the preferred way of the really competent users to do this, again keeping in mind that I want to loop over page numbers in a pdf file and thus am coding in Lua. So far, I have tried or thought about: 1. Embedded xtable This is what I’m using now, an xtable of two columns for every A4 page. It works, but I wonder if it’s a good method. 2. combinations This appeared to be the most natural approach (because it’s what combinations are for), but I ran into expansion problems, added a few “function () end” in my code, but couldn’t make it compile. Combinations, combined with framed and externalfigure, are difficult to write in Lua - or am I too stupid to find the winning combination (sorry for the puns). 3. columns Again, this would seen like a natural approach, having every A4 page set up as two columns, but maybe that’s overkill? I’d be curious to know what you think!

[NTG-context] Xml - lua - context
Dear all,
For a small project, I have two questions (without MWE…) on processing xml via
Lua and context. I’ll write two messages so eager volunteers can reply more
easily!
So question one: given an xml structure like this
Introduction: the Iliad
Introduction: the Iliad
I want to typeset the section title with some added information. Since I’m
processing in a loop, I thought this would be easier in Lua, so I have
something like this:
local i = 0
local sessions = { “April 2”, “April 9”, “April 16” } -- etc.
function xml.functions.section(t)
i = i + 1
local raw_section = xml.text (t, "/sectiontitle")
local section_head = i .. ". session, " .. sessions [i] .. ": " ..
raw_section
context.startsection { title=section_head }
lxml.flush (t)
context.stopsection ()
end
However, this means that the section_head is serialized as a string and not
processed according to the xml setups, so I have “the Iliad” in my
typeset document. How can this be avoided? How can I have the ...
processed instead of serialized in the section title?
Thanks for looking at my code!
Thomas
