Configuration

scnvim is configurable from lua only. Here is an example configuration that you can copy and paste to your init.vim.

lua << EOF
local scnvim = require 'scnvim'
local map = scnvim.map
local map_expr = scnvim.map_expr
scnvim.setup {
  keymaps = {
    ['<M-e>'] = map('editor.send_line', {'i', 'n'}),
    ['<C-e>'] = {
      map('editor.send_block', {'i', 'n'}),
      map('editor.send_selection', 'x'),
    },
    ['<CR>'] = map('postwin.toggle'),
    ['<M-CR>'] = map('postwin.toggle', 'i'),
    ['<M-L>'] = map('postwin.clear', {'n', 'i'}),
    ['<C-k>'] = map('signature.show', {'n', 'i'}),
    ['<F12>'] = map('sclang.hard_stop', {'n', 'x', 'i'}),
    ['<leader>st'] = map('sclang.start'),
    ['<leader>sk'] = map('sclang.recompile'),
    ['<F1>'] = map_expr('s.boot'),
    ['<F2>'] = map_expr('s.meter'),
  },
  editor = {
    highlight = {
      color = 'IncSearch',
    },
  },
  postwin = {
    float = {
      enabled = true,
    },
  },
}
EOF

Start

Open a new file in nvim with a .scd or .sc extension and type :SCNvimStart to start SuperCollider.

Commands

Command	Description
SCNvimStart	Start SuperCollider
SCNvimStop	Stop SuperCollider
SCNvimRecompile	Recompile SCClassLibrary
SCNvimGenerateAssets	Generate tags, syntax, snippets etc.
SCNvimHelp <subject>	Open help for <subject> (By default mapped to K)
SCNvimStatusLine	Start to poll server status to be displayed in the status line

Additional setup

Run :SCNvimGenerateAssets after starting SuperCollider to generate syntax highlighting and tags.

The plugin should work "out of the box", but if you want even more fine-grained control please have a look at the configuration section in the wiki.

Documentation

• :help scnvim for detailed documentation.
• API documentation

Extensions

The extension system provides additional functionalities and integrations. If you have made a scnvim extension, please open a PR and add it to this list!

• fzf-sc
  • Combine the magic of fuzzy searching with the magic of SuperCollider in Neovim
• nvim-supercollider-piano
  • Play SuperCollider synths using your (computer) keyboard in neovim!
• scnvim-tmux
  • Redirect post window ouput to a tmux pane.
• scnvim-logger
  • Log post window output to a file (example scnvim extension)

Supported platforms

• Linux
• macOS
• Windows (tested with nvim-qt and nvim.exe in Windows PowerShell)

Note to Windows users

The path to sclang.exe needs to be specified in the config:

local scnvim = require 'scnvim'
scnvim.setup {
  sclang = {
    cmd = 'C:/Program Files/SuperCollider-3.12.2/sclang.exe'
  },

Modify the sclang.cmd to point to where SuperCollider is installed on your system.

Additionally, to be able to boot the server you will need to add the following to startup.scd:

if (\SCNvim.asClass.notNil) {
  Server.program = (Platform.resourceDir +/+ "scsynth.exe").quote;
}
