HOWTO: add support for .rhtml, .html.erb, .rjs, .rxml, .builder

[Eric_Jardas]

After you installed Ruby on Rails its time to add support for it's extensions.

1. First we need to add new extensions to file mime.types located in /etc folder.

1.1 Lets do that. We have to add new extensions at the end of mime.types file. We'll do that with the following command:

echo -e "text/x-ruby-source                    rhtml html.erb \ntext/x-eruby                    rjs \napplication/xml                    rxml builder"  | sudo tee -a /etc/mime.types

1.2 Now we have to update mime-types so our new extensions get loaded with:

sudo update-mime-database /usr/share/mime

2. Now it's time to download files.tar.gz from attachment

2.1 Unpack it with command:

 tar -xzvf files.tar.gz

2.2 Now we have to copy .xml file to /usr/share/mime/package:

sudo cp x-rhtml.xml /usr/share/mime/packages

2.3 And .lang files to /usr/share/gtksourceview-1.0/language-specs:

sudo cp *.lang /usr/share/gtksourceview-1.0/language-specs

And we are done ! Now editors like gedit can recognize rails extensions and you have syntax coloring for them !

Enjoy !
