Dear Lua users,
I face a situation I do not understand.
I wrote a simple file "essai.lua" containing :
--
function essai1()
print(debug.getinfo(1,"n").name)
end
essai1()
--
When I do
$ lua essai.lua
essai1
This is logical to me.
Now, if I start lua and *copy and paste* the same code as in
"essai.lua", I have
$ lua
Lua 5.3.4 Copyright (C) 1994-2017 Lua.org, PUC-Rio
function essai1()
print(debug.getinfo(1,"n").name)
end
essai1()
nil
I do not understand why in one case, I obtain "essai1" (expected) and in
the second case, I obtain nil ?
I know that functions in lua do not have a fixed name and getinfo(1,"n")
is in charge to find an appropriate one.
But why are the results so different in a so simple example. Is it a bug
?
