Hi again Wolfgang and Peter,
The solution you provided to my problem is great but has a small issue…

\RandomCoeff{Alpha}{1}{10}

\define[3]\RandomCoeff{%

matter of fact, after reading your message I searched in

I have not yet figured out how to read values from a file in Lua and
just tried to print a constant to the gnuplot command.
I tried the following.
\usemodule[gnuplot]
\startGNUPLOTscript[lua]
plot \ctxlua{context(1.2 * x + 3
rk (I didn't
try it) would be the following:
\startGNUPLOTscript[name]
plot sin(x) t '$\pi = \ctxlua{math.pi()}$'
\stopGNUPLOTscript
How can you explain to ConTeXt whether lua command has to be executed
before or after gnuplot does its job? (label width will be wrong in

Sorry, that should have been
\ctxlua{"\detokenize{...}"}
which takes
uatex sets locale to "C".
To see the differences in the environment, just do "set >/tmp/set-shell"
and run context on:
--8<---cut here---start----->8---
\starttext
\ctxlua{os.execute"set >/tmp/set-context"}

Usinng the following

[filter={cat \externalfilterinputfile\space | tee

- If that also fails, then a simple markdown file with a unicode letter.
- If that also fails, then some other program that reads a file and writes
its contents to another file.
- Manually execute the shell command from inside ConTeXt using

There is no interface to increment the counter by arbitrary amount, but
you can define your own interface to structures.counters.add:
\unprotected
\def\addtostructurecounter [#1]#2{\ctxlua{structures.counters.add
("\@@thestructurecount
ups xml:pb
\def\svopage{\xmlatt{#1}{n}.}
\xmlflush{#1}
\stopxmlsetups
\startluacode
function filter(lb)
if math.mod(lb,5) == 0 then
context.svopage()
context(lb)
end
end
\stopluacode
\define[1]\MyNumber%

local l = lists.result[n]
local t = l.titledata

are the same as using texexec, not context.
IIRC, there were some security concerns with MkIV:
\ctxlua{os.execute("cat /etc/passwd")}
Althoug I admit that I tested it long ago (early days of mkiv) there is
some control built in:
system.executionmode
system.executionlist
the mode
