Sublime ENSIME

This project provides integration with ENSIME and Sublime Text Editor 2. It's a fork of the original sublime-ensime project, written by Ivan Porto Carrero. This fork introduces additional features, stability improvements, user-friendly setup and error messages, better logging.

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.

Project status

11.08.2013: Due to chronic lack of time, current SublimeScala team decided to step down from the project.

We are currently looking for folks who would take up the challenge of maintaining sublime-ensime.
This implies addressing the remaining integration problems (e.g. dealing with unicode properly or 
figuring out why ENSIME frequently fails "go to definition" requests) and implementing the features
that you find useful (e.g. refactorings, add missing import, better debugging, etc).

The foundation of the plugin (logging, process hosting, remote communications, state sharing between
plugin components) looks more or less solid, so contributing is usually about doing useful things
rather than fighting with the infrastructure. Therefore, if you're interested in having an intelligent
and customizable development tool for Scala, this project will be a fun way to spend your time.

This is a beta version. Basic things will work (for example, error highlighting), but there might still be problems. Please submit issues to our tracker if you catch SublimeScala misbehaving: https://github.com/sublimescala/sublime-ensime/issues/new.

Features

  • 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.

How to install?

  1. Install the package itself:

    a. If you use Package Control, install package Ensime. (Preferences > Package Control > Install Package > Ensime).

    b. Otherwise install manually. In your Sublime Text Packages directory, invoke:

    git clone git://github.com/sublimescala/sublime-ensime.git Ensime
    

    You can find the Packages directory by opening Sublime, selecting View > Show Console and then running the sublime.packages_path() command. Make sure you're using the right directory, or the plugin won't work.

  2. Install the ENSIME server:

    Download Ensime from http://download.sublimescala.org. The archive will contain a directory with an Ensime version.

    Make sure to download the build which matches your Scala version. The primary development platform of Ensime is 2.10.x, but 2.9.x is supported as well (though availability of builds of 2.9.x might lag behind). Every once in a while, the plugin might undergo updates which will require fresh Ensime builds. If there's no 2.9.x build of required version, please ping us or compile Ensime from sources (it's as easy as running sbt ++2.9.2 package).

    Extract the contents of this directory into the server subdirectory of just created Ensime directory. If you do everything correctly, Ensime/server/bin will contain Ensime startup scripts and Ensime/server/lib will contain Ensime binaries.

  3. (Re)start Sublime Text editor.

  4. Configure Ensime.

    a. Use Preferences > Package Settings > Ensime (Windows/Linux) or Sublime Text 2 > Preferences > Package Settings > Ensime (Mac) to configure different aspects of this plugin.

    b. By default Ensime customizes mouse bindings. It makes Ctrl+Click/Cmd+Click invoke Go to Definition and Alt+Click stand for Inspect Type at Point. If you want to disable these bindings or change them bindings to something else, adjust the config at Preferences > Package Settings > Mousemap - Default.

    c. For Windows users, make sure the Line Endings setting is set to Unix. You may do this by going to View > Line Endings and selecting Unix.

How to use?

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.

Troubleshooting

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.
