Many thanks to you Akira.
Reading the file into lua tables is good sense, and thank you for the string
manipulations to pass to metafun().
From your teaching I changed this
I seek how to use context-lua to draw a path from ‘points’ in an external file.
Below is one way to plot points from an external file, call the file DATA with
contents:
1 3
-2 2
-3 -1
3 -2
\starttext
\startluacode
local metafun = context.metafun
metafun.start()
io.input(“DATA)
