Code analysis server for Crystal programming language

crystal, language-server-protocol
brew install scry



Scry is a code analysis server for Crystal. It is an implementation of a common language protocol. It is being built as a server for VSCode, but is compatible with any client that implements this protocol.

The server is implemented in Crystal.


Scry will be distrubted as part of the Crystal IDE extension for VSCode.

TODO: Binary distrubtions

You can also add it to your shard.yml:

    github: kofno/scry
    version: ~> 0.1


Install on your path and then run Scry at the command line.

$> scry

Development && Roadmap

Ongoing, in my free time.

The goal is too implement all of the currently supported Language Server Features.
