Enable word wrap in JupyterLab code editor

Question

I would like to enable word wrap for the code cells in jupyterlab, but do not manage to find how.

Already tried:

• File --> Settings --> Text Editor --> User Overrides:{"lineWrap": true}, which toggles the greyed-out "word wrap" in the "Editor" menu, but does not solve my problem
• This code also did not work (neither did simply "Cell": {...} ):

"CodeCell": {
    "cm_config": {
      "lineWrapping": true
    }
  }

Answer 1

Try the following,

{
   "codeCellConfig": {
      "lineWrap": "wordWrapColumn",
      "wordWrapColumn": 80
   }
}
