I need to add a new language in Gedit. The problem is, it is included in Gedit menu of languages now, but its syntax is not highlighted and Gedit is not able to indentify the language just from the file suffix.
I've created both .lang file and a XML file describing MIME-TYPE.
LANG file - /usr/share/gtksourceview-3.0/language-specs/test.lang MIME-TYPE file - /usr/share/mime/packages/test.xml After creating them I've updated the mime database.
sudo update-mime-database /usr/share/mime Next attempts
1) I've tried even copying test.xml file to /usr/share/mime/applications folder instead of /usr/share/mime/packages, but it had no effect.
2) I've tried to put the mime type into the /etc/mime.types as
text/x-test test
and it had no effect too.
test.lang

<definitions>block lacks the main<context id=test">to start with. As per the docs - scroll down to<definitions>: Here we should define a main context, the one we enter at the beginning of the file[ ...] with an id equal to the id of the <language> element
