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/mime2. Now it's time to download files.tar.gz (http://ubuntuforums.org/attachment.php?attachmentid=34843&stc=1&d=1181429596) 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-specsAnd we are done ! Now editors like gedit can recognize rails extensions and you have syntax coloring for them !

Enjoy !

Do you know how you might get this working in gutsy? Since in gutsy there is now gtksourceview1.0 and gtksourceview2.0, I tried putting these files in both, and I still can't get the source to highlight in gedit.

I can't get rhtml to be recognized in gutsy either. Can anyone please help??

Finally got syntax highlighting for rhtml, rjs, ect in gedit on Gutsy working!!

Hope this helps others:
Ubuntu 7.10, rails, gedit and gtksourceview 2.0 (http://robzon.aenima.pl/2007/10/ubuntu-710-rails-gedit-and.html)

Thanks for the info.

Side note: why the **** should I register to get attached files? Is administration of this forums in desperate need of trash accounts?

I followed these instructions and was not able to get syntax highlighting for erb files working. I'm using Ubuntu 10.04.

My ruby syntax highlighting for .rb files works fine.

Now I discovered that everything does indeed work properly. My confusion stemmed from the fact that gedit saves what highlighting syntax you used last time you opened the file. Therefor, any html.erb files that I had opened before following these instructions had saved that they should be open as plain text. All html.erb files that I create from scratch open up with rhtml syntax highlighting. Hooray!
