  • Supports on-demand loading
  • Context aware evaluation (like Cmd-Enter in ScIDE)
  • Flashy eval flash (configurable)

  • Display SuperCollider documentation inside nvim
    • Be able to evaluate examples

Supported platforms

  • Linux
  • macOS
  • Windows (tested with nvim-qt)




  1. Install SuperCollider.
  2. Add this line to your init.vim if you are using vim-plug.
Plug 'davidgranstrom/scnvim', { 'do': {-> scnvim#install() } }

Source init.vim (or restart nvim) and then run :PlugInstall.

Modify the above to match your package manager of choice, or do a manual install using vim packages.


  1. Run :call scnvim#uninstall()

    • You could always delete the symbolic link (scide_scnvim) from your Extensions directory manually if you forget this step.
  2. Remove the plugin according to how you've installed it (see Install above.)


If something doesn't work with the installation method above, the first thing to try is :checkhealth scnvim. This will give you an indication on what's not working, and information on how to resolve the issue.

If you want to do complete a manual installation look here and here.

Starting SCNvim

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


The following sections can be accessed in :help scnvim as well.


Map Description Name Mode
<C-e> Send current block or line (depending on context) <Plug>(scnvim-send-block) Insert, Normal
<C-e> Send current selection <Plug>(scnvim-send-selection) Visual
<M-e> Send current line <Plug>(scnvim-send-line) Insert, Normal
<F12> Hard stop <Plug>(scnvim-hard-stop) Insert, Normal
<CR> Toggle post window buffer <Plug>(scnvim-postwindow-toggle) Insert, Normal
<M-L> Clear post window buffer <Plug>(scnvim-postwindow-clear) Insert, Normal
C-k Show function signature for object under cursor <Plug>(scnvim-show-signature) Insert, Normal
K Open documentation Uses vim keywordprg Normal

You can remap all of the default mappings using the <Plug> mappings in the table above. Notice the usage of nmap rather than nnoremap in the following examples, since we actually want to map to the <Plug> mappings recursively.


nmap <F5> <Plug>(scnvim-send-block)
imap <F5> <C-o><Plug>(scnvim-send-block)

To disable a specific mapping use <nop>.

nmap <nop> <Plug>(scnvim-show-signature)

To disable all default mappings use let g:scnvim_no_mappings = 1


Command Description
SCNvimStart Start SuperCollider
SCNvimStop Stop SuperCollider
SCNvimRecompile Recompile SCClassLibrary
SCNvimTags Create auto-generated utility files
SCNvimHelp <subject> Open HelpBrowser for <subject>
SCNvimStatusLine Display server status in status line

Additional setup

Run :SCNvimTags after starting SuperCollider to enable syntax highlighting (note that the current buffer must be reloaded for this to take effect).

Note There is a known bug where sclang will crash immediately after running :SCNvimTags. This will hopefully be resolved in the future.

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

Note to Windows users

To be able to boot the server you will need to add the following to your startup.scd:

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