Use ggtags mode for CFEngine3

Use ggtags-mode for CFEngine3

• Following the instruction here https://github.com/leoliu/ggtags#install-global-and-plugins to build global with support for ctags and pygments.

• Configure ctags to support CFEngine3 by adding the following lines to ~/.ctags:

--langdef=CFEngine3
--langmap=CFEngine3:.cf.cf3
--regex-cfengine3=/^[ \t]*bundle[ \t]+[[:alnum:]_]+[ \t]+([[:alnum:]_]+)/\1/B,bundle/
--regex-cfengine3=/^[ \t]*body[ \t]+[[:alnum:]_]+[ \t]+([[:alnum:]_]+)/\1/b,body/

• Change ~/.globalrc to include CFEngine3:

diff -u /home/leo/.globalrc /usr/local/unix/global/share/gtags/gtags.conf

• Copy ~/.globalrc to your CFEngine3 project directory and rename it to gtags.conf. Edit gtags.conf to have the default index backend set to pygments.

After all the hard work you should be able to navigate CFE3 projects with ease. A screenshot:
