Hi,
I’m trying to get a simple function with a variable number of
parameters working:
"""
\startluacode
interfaces.implement {
name = "Autoren",
public = true,
arguments = { "hash" },
actions = function(t)
logs.report('Autoren', 'interface got table of length ' .. #t)
end
}
\stopluacode
\starttext
Info:
\Autoren[text=Hans,melody=Hraban]
\stoptext
"""
The table t has always length 0. Where’s my error?
Do you see the difference?
\starttext
\startluacode
a = { "one", "two", "three" }
b = { x = "one", y = "two", z = "three" }
context("Table a: " .. #a)
context.par()
context("Table b: " .. #b)
\stopluacode
\stoptext
Wolfgang
Oops, yes: #count is not for string indices.
Thus I shouldn’t break if #t==0.
BTW is there a function for printing a table (like pprint.pprint in Python)?
The other problem was I had a return instead of context().
Thank you for the hint!
Hraban
