[Updated: 2008/12/10]
This is how I set up /Lift/, ctags, and vim (on OS X and Ubuntu):
Add some scala definition to ctags:
ty@Astra:~$ cat /home/ty/.ctags
--langdef=scala
--langmap=scala:.scala
--regex-scala=/^[ \t]*class[ \t]+([a-zA-Z0-9_]+)/\1/c,classes/
--regex-scala=/^[ \t]*trait[ \t]+([a-zA-Z0-9_]+)/\1/t,traits/
--regex-scala=/^[ \t]*type[ \t]+([a-zA-Z0-9_]+)/\1/T,types/
--regex-scala=/^[ \t]*def[ \t]+([a-zA-Z0-9_\?]+)/\1/m,methods/
--regex-scala=/^[ \t]*val[ \t]+([a-zA-Z0-9_]+)/\1/C,constants/
--regex-scala=/^[ \t]*var[ \t]+([a-zA-Z0-9_]+)/\1/l,local variables/
--regex-scala=/^[ \t]*package[ \t]+([a-zA-Z0-9_.]+)/\1/p,packages/
--regex-scala=/^[ \t]*case class[ \t]+([a-zA-Z0-9_]+)/\1/c,case classes/
--regex-scala=/^[ \t]*final case class[ \t]+([a-zA-Z0-9_]+)/\1/c,case classes/
--regex-scala=/^[ \t]*object[ \t]+([a-zA-Z0-9_]+)/\1/o,objects/
--regex-scala=/^[ \t]*private def[ \t]+([a-zA-Z0-9_]+)/\1/pd,defs/
Build the tags file:
ty@Astra:~$ /opt/local/bin/ctags -h ".scala" -R --exclude=*.js -f liftags /Users/tjweir/g/clean/liftweb/
I prefer to keep the tags file, in this case liftags, in the root of home. Put it where you want.
Add the tags location to ~/.vimrc
set tags=/home/ty/liftags
Now you can open a file and execute
:tag LiftSession
and jump to the file.
