Hi, I use Gnome on my computer and sometimes I use its default text editor gedit. It uses gtksourceview library for syntax highlighting. I decided that it would be nice if gedit supported R syntax. So I created apropriate .lang file: http://bugzilla.gnome.org/show_bug.cgi?id=157370 Gedit picks apropriate lang file according to file mimetype, so I created apropriate mime type for files with extension .R. I filed a bug report at freedesktop.org: https://freedesktop.org/bugzilla/show_bug.cgi?id=1782 There Christophe Fergeau suggested that maybe R could take care of installing this mime type by itself. So my question would be could R do this? Feel free to make any suggestions concerning mime type, or syntax highlighting file. Vaidotas Zemlys
