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

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
