Configuration

-- default values:
opts = {
  autorun = false,
  layout = "webchuck", -- or "chuck_on_top"
  chuck_vm = {
    log_level = 1,
    srate = 44100,
    bufsize = 512,
    dac = 0,
    adc = 0,
    channels = 2,

},

Usage

chuck-nvim provides the following functions to interact with the ChucK VM.

ChuckLoop

Starts ChucK in loop mode with chuck --loop using the configuration values.

Tip

You can enable autorun to launch ChucK and the UI automatically.

ChuckStatus

Prints current time and active shreds status in the ChucK VM.

ChuckTime

Prints the ChucK VM's full time information in the ChucK VM.

ChuckAddShred

Adds the current saved buffer to the ChucK VM, as an active shred.

Note

You must save file changes beforehand.

ChuckRemoveShreds

Prompts the user for shred(s) number(s), then removes them from ChucK.

Tip

To remove more than one shred, enter the numbers separated by spaces.

ChuckReplaceShred

Prompts the user for a shred number, then replaces it with the current buffer.

ChuckClearShreds

Removes all active shreds.

ChuckClearVM

Removes all active shreds and resets the type system.

ChuckExit

Cleanly exits the VM, cleans out logs, and quits ChucK.

Key mappings

chuck-nvim doesn't set any key mappings by default. Below, an example configuration for LazyVim.

Warning

Make sure these don't conflict with existing mappings.

Tip

You could map the commands to function keys to speed up operations.
