Hello.

I have a complie error on this simple code :

#si c'est un caractere ?
if char=~/\w|\s/i then
@buffer+=char
@position+=1

else if id==14 then
#backSpace
@buffer=@buffer[0..@buffer.length-2]
@position-=1

else
puts "caractere non reconnu : #{id}"

end

I really don't get why.
Any Idea ?

Thanks by advance.

Ruby uses "elsif" keyword instead of "else if" combination.

Use "elsif" or "case"

case
when /\w|\s/i =~ char
then
...
when id == 14
then
...
else
...
end

elseif if not working, I don't understand why, that's why I also tried
"else if".
but case is working fine. I just didn't know we could make tests with
when oher than === (that's described in my reference book).

thanks for all this help, I can go on now.
Regards.

no --^ 'e' here. Fixes the problem. No?

Proper indentation will get you a clue:

if char=~/\w|\s/i then
@buffer+=char
@position+=1

else if id==14 then
#backSpace
@buffer=@buffer[0..@buffer.length-2]
@position-=1

else
puts "caractere non reconnu : #{id}"

end

Your are missing one end statement at the end...
