Hello
We like Lua for its facility in self-declarative data description. But I
am Spanish and I want to prepare a program that need table field names
with accented characters. Yes, I know the problem of portability, but
we could prepare a version for every language I want.
I know that the format table["blá"] is always possible, but it is
cumbersome because other (non programmers) people will be the users of
my program. Concretely the user will introduce in a file (it is only a
simplified example):
-----------method_1--------------
Entrada1 {
título = "Algún libro", -- simple
año = 1992
}
--------------------------------
instead of:
-----------method_2--------------
Entrada2 {
["título"] = "Algún libro", -- cumbersome
["año"] = 1992
}
--------------------------------
The program, that will process the previous chunk with dofile(), could be:
-----------method_2--------------
function Entrada1 (o)
print(o["título"])
print(o["año"])
end
--------------------------------
but it will be better to use:
-----------method_1--------------
function Entrada1 (o)
print(o.título)
print(o.año)
end
--------------------------------
(This part of the problem is not very difficult, as I could use method_2
inside the code.)
I have a Debian Linux (frequently updated).
In this machine method_2 obviously works.
But method_1 works ONLY if I type the program INSIDE
the Lua intrepreter (I tried versions 5.0 and 5.1)!
For example if I do
lua method_1
the intrepreter protests:
lua: method_1:3: ')' expected near 'í' --in the í of título in Entrada1
----------------------------------------
Note.-
I have the locale:
LANG=es_ES@euro
LC_CTYPE="es_ES@euro"
LC_NUMERIC="es_ES@euro"
LC_TIME="es_ES@euro"
LC_COLLATE="es_ES@euro"
LC_MONETARY="es_ES@euro"
LC_MESSAGES="es_ES@euro"
LC_PAPER="es_ES@euro"
LC_NAME="es_ES@euro"
LC_ADDRESS="es_ES@euro"
LC_TELEPHONE="es_ES@euro"
LC_MEASUREMENT="es_ES@euro"
LC_IDENTIFICATION="es_ES@euro"
LC_ALL=
----------------------------------------
I think this is also a problem with with luacheia and lua in Windows XP.
Why the interactive lua works differently than the non-interactive one
(in this subject)?
What is the solution? I read many posts in lua-l archive but I have
found none.
Thank you in advance.
