Accentuated function names

Jean-baptiste Hétier

12/15/2008 9:21:00 AM

Hello,

I've started a new project in Ruby. For once, my sourcecode is not in
English, but in French, and I'd like to know if its possible to have
accentuated letters for function names in the sourcecode.

I have encoded my file in UTF-8 and it is parsed fine on Linux, but on
Windows, I get warnings and errors:
main.rb:16: Invalid char `\303' in expression

Also, the accents do not display properly in the error messages:
main.rb:34: syntax error, unexpected tFID, expecting '\n' or ';'
def apprâ??®cie?(voisin)
(instead of "apprécie?(voisin)")

Is there a way to specify sourcefile encoding? I could drop the accents
in the source, but they make the code much more readable!

Thanks.

Thanks for your answer!

Yeah, I'll probably switch back to English... but I'm still interested
in a solution. In Python you can define the file encoding in some kind
of file header:
#!/usr/bin/python
# -*- coding: <encoding name> -*-
I'm sure there's a way to do that in Ruby as well, but couldn't find it
anywhere :(

Mmmh, I just found the following link:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-...

It probably hasn't been implemented yet... Oh well...

It has. In Ruby 1.9.

Ne te laisse pas dominer par le langage ! La solution c'est de passer
de MatzacredLisp à Common Lisp (par exemple: http://clis...) :

C/USER[4]> (defun décrémenter (x) (1- x))
DÉCRÉMENTER
C/USER[5]> (décrémenter 42)
41
C/USER[6]>

AFAIK, python doesn't use that line.
It's emacs that uses to store buffer local variables.

All my scripts start with:

#!/usr/bin/clisp -ansi -q
;; -*- mode:lisp; coding:utf-8; -*-

As it was already said, 1.9 does support the Encoding string but for 1.8, you may want to try adding "-Ku" to your Ruby invocation.

395 [14:46] roberto@roberto-al:/tmp> ruby -Ku foo.rb
Bonjour
396 [14:46] roberto@roberto-al:/tmp> cat foo.rb
#! /opt/local/bin/ruby -Ku
#
def été(foo)
puts(foo)
end

été("Bonjour")

With foo.rb written with utf-8 encoding.
