Feature request: jump to declaration #140

Closed Pitometsu closed 7 years ago

Is it possible to achieve "jump to symbol declaration" in swift-mode?

We can use ctags:

  1. Append this ctags setting from swift.vim to ~/.ctags.
  2. Run find . -name '*.swift' -print0 | xargs -0 ctags -e in your project root directory. This will create an index file named TAGS. We need Exuberant Ctags or universal ctags. ctags bundled with Emacs does not seems to work. If you get Invalid character class name error, replace [[:<:]] and [[:>:]] in the .ctags file with \b.
  3. Type M-. in Swift code. Emacs may ask you where is TAGS file.

Alternatively, we may able to utilize SourceKit, SourceKitten, and/or SourceKittenDaemon to be smarter, but it will need a lot of work.

Confirm: universal ctags works enough good. Many thanks!
