Do you confirm the problem? Any way/plan to fix it?

i'm not surew what goes wrong there but you can best run with

I actually already wrote parts of my invoicing solution in Lua. I was planning to even run a simple GUI (tekui) on top of LuaTeX, but my priorities keep shifting... At the moment I got shell scripts that call Python scripts that read JSON files (as a simple database) and write ConTeXt code that includes (object oriented) Lua libraries for most of the the calculations... It works well enough for my own company and our publishing house, but is quite convoluted.

I thought about providing a module, but each of my projects has so differing
needs that either every macro would need a bunch of options, or I need a lot of
similar macros. We’ll see...
my experience in these situations:
I'm usually implementing complicated solutions via Lua, with functions with
obligatory arg(s) first followed by one optional argument of table type:
- it's easy to investigate this optional argument and alter the algorithm
depending on table keys (presence and/or value),
- you don't have to be afraid of optional arg(s) rearrangement.
To be more concrete:
Sample Lua code
MyPlaceFigure = function(figname,
opts) -- Optional; .scale = .sc, .rotation = .rot,
.label, ...
opts = opts or {} -- To simplify code bellow
local scale, rot, lab =
opts.scale or opts.sc, -- I.e. more keys are allowed in long/short
alternative
opts.rotation or opts.rotate or opts.rot, -- dtto
opts.label or opts.lab,
nil
if label then
-- E.g. use context.placefloat(...)
else
context.externalfigure({figname}, {scale = 1000 * scale, orientation = rot,
})
end
end
Best regards,
Lukas

Dear Lukáš, thank you very much for collecting this information! I’ll try as soon as I get some time, since algorithmic image placement is a recurring problem for me, as I try to replace InDesign in my workflow. I thought about providing a module, but each of my projects has so differing needs that either every macro would need a bunch of options, or I need a lot of similar macros. We’ll see...

Re: [NTG-context] image file resolver in Lua?
Hello Henning,
This is really interesting, but my original question was about the file path resolver, i.e. how to
get "t:/sources/cow.pdf" from just "cow"?
I guess there was a similar question here:
https://mailman.ntg.nl/pipermail/ntg-context/2017/088324.html
Reading till the end, I deduce one has to collect snippets which appear in the code to build its
own "file locator" as no function like "MyExternalFigureLocator()" exists in
ConTeXt/Lua API.
Some highlights:
Personally I use the lua variable named : figures.path
It’s a lua table which contains directories names you provide in directory= in
\setupexternalfigures:
for _, path in ipairs(figures.paths) do
local figure_file = path .. '/' .. file
local doc = lpdf.epdf.load(figure_file) -- assume pdf (just an example)
if doc then
….
end
done
Unfortunately, this code supposes the figure name was passed WITH extension, as
no lookup in table-of-valid-extensions is performed (maybe no such table nor
iterator exists).
There should be also:
local n =
"x:/Users/MMi/Akce/I-6_Krusovice.DSP-ZDS/Admin/Jednani/2017-07-07-SU-Rakovnik/ZJ.pdf"
local d = figures.getinfo(n)
inspect(d)
And a snippet from another mailing thread:
(Hans' answer)
\getfiguredimensions[test.pdf]
\dorecurse {\noffigurepages} {
\getfiguredimensions[test.pdf][page=#1]
\figurenaturalwidth
,\figurenaturalheight,\figureorientation,\figurerotation\par
}
in lua you can either use the img library (see luatex manual) or context
helpers
local data = figures.push("foo.pdf")
figures.identify()
figures.check()
figures.pop()
inspect(data)
i'll add:
function figures.getinfo(name,page)
if type(name) == "string" then
name = { name = name, page = page }
end
if name.name then
local data = figures.push(name)
figures.identify()
figures.check()
figures.pop()
return data
end
end
so that one can do
local n = "ms.pdf"
local d = figures.getinfo(n)
if d then
for i=1,d.used.pages do
local p = figures.getinfo(n,i)
if p then
local u = p.used
print(u.width,u.height,u.orientation)
end
end
end
Hope this helps.
Best regards,
Lukas
