This could be the problem, registering classes is usual in .pd_lua files 
but not .pd_luax files.

  
I haven't really understood how to build a pd_luax file then... nevermind.

  
function LSpell:initialize(name, atoms)
    self.outlets = 1
    self.inlets = 1
    return true
end

function LSpell:in_1_symbol(s)
    pd.post("received :" .. s)
    word = get_word_from_inlet()
    cmd = "aspell -c " .. word
    p = assert(io.popen(cmd))
    result = p:read("*all")
end

I know there is no output yet but the code is bugging at the 
get_word_from_inlet() function.
    

where did you define get_word_from_inlet?  You should just be able to 
use 's', as that's the symbol atom passed to the inlet method.
  
mmh sure, I just used that cause that was the part of code frank mentionned and thought this was a kind of pd secure-interacting functions.
  
When I do :

[symbol toto(
|
[lspell]

pd prints:

received :toto
error: lua: error in dispatcher:
[string "lspell.pd_luax"]:14: attempt to call global 
'get_word_from_inlet' (a nil value)

I have no really idea of the way pdlua manage functions and everything. 
Must I dig more into the pd_lua examples or is this only a lua problem I 
can handle if searching universal lua docs?
    

This seems to be a Lua problem more than a pdlua problem - you use 
get_word_from_inlet() but don't define it anywhere.

A pdlua manual is on my todo list, but for now the examples are the best 
documentation.

  

I manage to get it work with this code:

function LSpell:in_1_symbol(s)
    word = s

    cmd = "echo " .. word .. " | /sw/bin/ispell -a | grep \\*"

    p = assert(io.popen(cmd))

    result = p:read("*all")
    if(string.len(result) ~= 0) then
      self:outlet(1, "symbol", {word})
      end

end

It outputs the word only if it exists in ispell.

Can Lua be used as a more stable shell interpretor for all the functions?
It is of a big interest!!

Thanks to all,

Nicolas
