csound-mode

This package provides both a basic major mode for editing Csound files, as well as a REPL for fast feedback when composing/sound-designing using Csound.

csound-mode provides a set of essential features for interactive development:

• REPL
• Interactive code evaluation
• Code completion
• ElDoc
• Indentation rules
• Syntax highlighting and rainbow delimited score parameters

Installation

You can install csound-mode from MELPA using the following command:

M-x package-install [RET] csound-mode [RET]

Alternatively, download latest release. and add it manually to load-path like shown here:

;; Change directory path according to csound-mode dir location.
(add-to-list 'load-path "~/.emacs.d/csound-mode/")
(require 'csound-mode)

Requirements

• Emacs 25+
• Csound 6.10+ (any release/compilation after 1. December 2017)

Usage

csound-mode comes with major-mode-hooks, meaning that every time a csound file(.csd/.orc/.sco) is opened in emacs, csound-mode will be automatically loaded as major mode. While making it easier to install, this could potentially overwrite other major-mode you have set for csound files.

If you're using csound-mode directly from the git repo, and you happen to use the use-package macro. Then this could be used in your init.el file.

(use-package csound-mode
  :mode (("\\.csd\\'" . csound-mode)
     ("\\.orc\\'" . csound-mode)
     ("\\.sco\\'" . csound-mode)
     ("\\.udo\\'" . csound-mode))
  :load-path "packages/csound-mode/")

With more options

(use-package csound-mode
  :ensure t
  :custom
  (csound-skeleton-default-sr 96000)
  (csound-skeleton-default-ksmps 16)
  (csound-skeleton-default-options "-d -oadc -W -3")
  (csound-skeleton-default-additional-header "#include \"PATH/TO/YOU/UDOs.udo\"")
  :mode (("\\.csd\\'" . csound-mode)
         ("\\.orc\\'" . csound-mode)
         ("\\.sco\\'" . csound-mode)
         ("\\.udo\\'" . csound-mode))
  :load-path "~/.emacs.d/elpa/csound-mode/")
