Jarek, I agree there's a danger but I think that being unidirectional is probably a small danger. That'd mean that a properties file in arabic would write the key-name (which is likely to be westernwritten from right to left), similarly for the jsp or php code. I think this is livable, I am not sure. As Mathieu underlined, it is not clear who would be working on such yet. paul Le 5 mars 2012 à 07:36, Jarek Czekalski a écrit : > I don't understand the reason to introduce RTL in jedit.
