Swift layer

  • swift-repl-mode

Description

This layer adds support for Apple's Swift programming language, used as a general purpose scripting language.

It relies on the swift-mode major-mode* for Emacs 24.4 or later, to provide the following features:

• Syntax highlighting
• Indentation
• Code navigation using imenu (built-in)
• Automatic syntax checking with flycheck (available with the syntax-checking layer)

Install

First check that you are able to run this from the command line:

On OS X:

  xcrun swift

Then to use this configuration layer, add it to your ~/.spacemacs. You will need to add swift to the existing dotspacemacs-configuration-layers list in this file.

Usage information

Unless configured by the user, the REPL will be invoked using the command xcrun swift. You can launch the REPL using the keybinding SPC m s s (or C-c C-z). The universal prefix SPC u (C-u) may be used to modify command invocation.

Key bindings

Notes:

1. swift-mode-run-repl will run or switch to an existing REPL.
2. To edit the command invocation, prefix with SPC u (or C-u).
3. Emacs key bindings in use are the those set by the package.
