Sublime Text Integration

Screenshot from Sublime Text 3

Our plugin for Sublime Text 3 enables you to interactively edit, evaluate and hear programs directly in your text editor.


The plugin is experimental, and the package is not in the Sublime package repository. You can grab the package from the Kronos source tree. You can put these files inside your Sublime Text packages folder in a folder called Kronos.

Once the plugin is installed, you can open Package Settings for Kronos. Please kronos.krpc_path at the binary for krpc, the subprocess repl server in the native compiler suite.

{ "kronos.krpc_path": "krpc" // default values for the runtime library loaded by krpc // "kronos.core_library_repository": "repository-slug" // "kronos.core_library_version": "repository-tag" }

You should probably ignore the commented-out settings for non-standard runtime libraries.


Syntax highlighting should kick in automatically when you are editing a .k file. The plugin adds a menu called Kronos which contains the functions and keyboard shortcuts that operate krpc.

By selecting the menu item Send to REPL or by pressing the appropriate shortcut, your selection is sent to the REPL and its output is shown inline, instarepl-style. The selection is expanded to complete lines: if there's no selection, the line the caret is at is evaluated.

You can get sound out similarly to krepl, by assigning to the special symbol snd. Alternatively, you can use Instantiate in REPL, which causes the selected expression to be instantiated as a signal processor. The instarepl bubble in that case has a clickable stop command.

If you lose track of sounding instances, you can use the Panic! command which should stop all running instances. Because the plugin is experimental, occasionally you might run into problems; you can restart the REPL with Kill the REPL Process. Be advised that this loses state, as in the definitions you have sent to the REPL so far.

Language Server

If you have the LSP package for Sublime Text 3, you can run an experimental language server for Kronos called klangsrv. You can integrate it with LSP with settings like this:

{ "only_show_lsp_completions": true, "clients": { "kronos": { "command": ["klangsrv"], "scopes": ["source.kronos"], "syntaxes": ["Packages/Kronos/Kronos.tmLanguage"], "languageId": "kronos" } } }

If klangsrv is not on your system path, edit command to point at the executable.
