SCTags is ctags and etags extractor for Scala language. It will fallback to ctags if language other than Scala was forced
sctags [-f|-o file] [-R|--recurse] [--list-languages] [--version] <files>
-f file | -o file
sets the file the tags are written to, default is "tags"
(Use "-" for standard output)
-R --recurse
recurse through directories specified on the command line
--list-languages
list the supported languages (inlcuding the ctags suported ones)
--language-force=lang
it will fall back to ctags if the lang is not Scala
--version
print fake version for exhuberant ctags compatibility
$ sbt assembly
$ cp target/scala-2.11/sctags ~/bin
The executable uncludes the compiled classes. It will look for the scala libraries relatively to the scala executable that should be on your $PATH. Other option is to set SCALA_HOME to the root of your Scala distribution or SCALA_LIB to the lib directory of SCALA_HOME.
function! SCTags()
if executable("sctags")
let g:tagbar_ctags_bin = "sctags"
let g:tagbar_type_scala = {
\ 'ctagstype' : 'scala',
\ 'sro' : '.',
\ 'kinds' : [
\ 'p:packages',
\ 'V:values',

endfunction
if has("autocmd")
autocmd FileType scala call SCTags()
endifThis will give you nice package/class/object/method hierarchy in Tagbar. Here is an example:
▼+types : package
▼+Membership : trait
+C[T] : type
+T : type
+contains(a:C[T], b:T) : method
▼+BloomFilterMembership : class
+T : type
+<init>() : method
+contains(a:BloomFilter[T], b:T) : m
▼+MinMaxMembership : class
+T : type
+<init>() : method
+contains(a:MinMax[T], b:T) : metho
▼+SetMembership : class
+T : type
+<init>() : method
+contains(a:Set[T], b:T) : method
▼+MembershipOps : object
▼+Contained : class
+C[T] : type
+T : type
[values]
-a
-tc
+<@(b:C[T]) : method
+<init>(a:T)(tc:Membership[T, C])

It is simplified and extended to support scope tracking.
