This project provides integration with ENSIME and Sublime Text Editor 2. It's a fork of a fork of the original sublime-ensime project, written by Ivan Porto Carrero. This fork fixes a small bug when starting a new ensime project without a

Sublime ENSIME strives to realize the dream of having Scala semantic services inside a lightning fast and feature-rich text editor. Big thanks to Aemon Cannon, Daniel Spiewak and Ivan Porto Carrero who demonstrated that this vision is possible and inspired us to kick off the project.

This fork was made by me (Shane) primarily for use by Originate, Inc's Scala training program.

This is a beta version. Basic things will work (for example, error highlighting), but there might still be problems.

• Natively targets Scala 2.10.x, also supports Scala 2.9.x.

• Creates and understands .ensime projects (maximum one project per Sublime window, if you have a project with multiple subprojects only a single subproject will be available at a time).

• Integrates with SBT to generate Ensime projects from SBT projects and provides a command, which runs SBT compilation for the current Ensime project.

• Once your Ensime project is configured (we have a helper for that) and Ensime is run, Scala files in that Ensime project benefit from a number of semantic services:

  • On-the-fly typechecking and error highlighting on save. Error messages are displayed in the status bar when you click highlighted regions (unfortunately, Sublime Text 2 doesn't support programmable tooltips). Moreover, errors can be viewed in a dynamically updated buffer displayed with Tools > Ensime > Commands > Show notes.

  • Type-aware completions for identifiers (integrates into the built-in mechanism of completions in Sublime Text 2, depending on your configuration it might be bound to Ctrl+Space/Cmd+Space or Tab).

  • Type-aware go to definition (implemented by ensime_go_to_definition command: bind it yourself to your favorite hotkey or use the default Ctrl+Click binding on Windows/Linux or Cmd+Click on Mac).

• Implements experimental support for debugging. At the moment you can set breakpoints, create launch configurations, step through programs in the debugger, inspect program output, navigate stack traces and watch values of local variables. Things are far from smooth, but it might be worth a try.

Follow the instructions at the scala course site

Open the Sublime command palette (typically bound to Ctrl+Shift+P on Windows/Linux and Cmd+Shift+P on Mac) and type Ensime: Startup.

If you don't have an Ensime project, the plugin will guide you through creating it.

If you already have a project, an ENSIME server process will be started in the background, and the server will initialize a resident instance of the Scala compiler. After the server is ready, a message will appear in the left-hand corner of the status bar. It will read either ENSIME if the currently opened file belongs to the active Ensime project or ensime if it doesn't. Keep an eye on this message - it's an indicator of things going well.

If you find that some features of Ensime are not working properly (i.e. Go To Definition or Error Highlighting), then check the Line Endings setting in Sublime Text 2. On Windows, the line endings is set to Windows by default. Simply change this setting to Unix by going to View > Line Endings and selecting Unix.
