VS Code language protocol

There is an increasing number of languages and IDEs supporting VS Code’s language agnostic server protocol.

While it is unclear from that email what your suggestion goal is. I can
say that this is something I had been looking into. I was originally
looking to use libIDE to generate something that would conform to this
protocol.

Though it now looks like SourceKit is coming to Linux so I'm in a
holding pattern to see what comes of that.

Long-story short I think this would be a great way to get some IDEs
besides Xcode for platforms besides OS X.

Out of curiosity have you started working on something?

This is very interesting, I opened a JIRA feature to keep track, and I’ve put some thoughts on how we could go about supporting this.

github.com/apple/swift

[SR-1878] Support the VSCode Language Protocol for Swift

opened 10:29PM - 22 Jun 16 UTC

We could create a tool executable that implements the json-rpc protocol by reading the json requests from stdin and outputting responses in stdout. It can use libIDE for the underlying Swift functionality, like providing code-completion. We also need to investigate a way to be able to get compiler arguments that should be associated with a particular swift file (like the proper search paths). An idea for that would be to extend SwiftPM/llbuild and get it to output a "compilation database" like the one that CMake generates and is used by clang tools (see <http://clang.llvm.org/docs/JSONCompilationDatabase.html).>

Any feedback is welcome!

Any chance to see this coming up in SourceKit ? It would help a lot in Swift adoption/world domination :)

It sounds like Apple agrees with you, and is looking at using some variation of the Language Server Protocol in a future release of Xcode, so chances it will get a lot easier for other IDEs/editors such as Microsoft's Visual Studio Code to more fully support Swift.

Are you sure they do? I couldn't parse all of the jargon in the email, so I'm probably wrong... but it sounded like they mean to put this feature only on Darwin.

tonyarnold · 2018-04-27T01:34:39.231Z

No, I'm not sure, but my reading of the mailing list post is that things appear to be headed in that direction. It was just an interesting bit of related information.

I'm sorry, I didn't mean it in a negative way. Thanks for sharing the info

tonyarnold · 2018-04-27T01:36:53.952Z

Not to worry, I didn't take it that way - you are right to ask for more information

I hope it is. First-party support for the LSP would be amazing :)

jechris · 2018-04-27T07:57:59.471Z

@tonyarnold thanks for the link. Indeed it seems that apple is moving into integrating LSP, that's good news! With some luck we'll see first steps into Xcode 10
@rlovelett Great work BTW
