[Support] Help getting documentation to work on Linux

[lf-araujo]

Thank you for this extension.

I am trying to use it in Linux, and clearly did not get something right.

Swiftkitten is installed and has been added to the $PATH, however the extension is not helping with completions or definitions. How can I help debug this?

I am running this in Ubuntu 17.10.

Best,

@lf-araujo Any luck figuring it out ❓ 😸

Unfortunately no, sourcekitten is only working on an older version of ubuntu, there is no support for archlinux at this moment.

Found a solution, here: jpsim/SourceKitten#524 @sus007

I had to move from Arch to Ubuntu with the hope for better support. Indeed sourcekitten is much easy to install, but I cannot make the documentation bit work under Linux. Am I under the wrong assumption that this package does not support documentation on Linux?

If I use sourcekitten doc inside a project directory, the software gives me the message: Running xcodebuild and nothing more, however when run with the --single-file flag it seems to work well except for some warning message at the beginning:

└─λ sourcekitten  doc --single-file main.swift 
sourcekit: [1:getCursorInfo: 0.0000] failed to create an ASTInvocation: error when parsing the compiler arguments{
  "\/home\/luis\/Dropbox\/Documentos\/Coding\/Swift\/SwiftGtk-example\/Sources\/main.swift" : {
    "key.diagnostic_stage" : "source.diagnostic.stage.swift.parse",
    "key.length" : 977,
    "key.offset" : 0,
    "key.substructure" : [
      {
        "key.accessibility" : "source.lang.swift.accessibility.internal",
        "key.kind" : "source.lang.swift.decl.var.global",
        "key.length" : 63,
        "key.name" : "app",
        "key.namelength" : 3,
        "key.nameoffset" : 21,
        "key.offset" : 17
      }
    ]
  }
}

Now when I open the project folder in Sublime completion seems to work well, but documentation for functions does not appear. In the console I get:

• What am I doing wrong? Does documentation works on Linux?
