Where can I activate or use, into c9.io IDE, the Fortran syntax file highlight? with vim O got it, but I like to use the same way the syntax into de ACE editor (is it the default editor?)
There is no syntax highlighting for fortran yet, if you know fortran you can help to create a highlighter for ace. See http://ace.c9.io/#nav=higlighter and http://ace.c9.io/tool/mode_creator.html
