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
   }
}

For reference, see this pull request from the JupyterLap project on GitHub.

I guess this was implemented since January. Just "lineWrap": "on" did the trick for me, but generally your answer is correct. Thank you for the reminder. – Gunar

Any chance that you know how to enable text wrapping on google colaboratory jupyter notebook? I have updated to the latest notebook: (5.7.8) but no text wrap option on text output is available on colaboratory. – Garratt

Sorry, but I can't help you there. – Box

This thread helped me to figure out where to put the settings. – Countermove

Answer 2

Here is how I solved it :

Settings -> Advanced Settings Editor -> Notebook to user preferences add

{"codeCellConfig": {
        
        "lineWrap": "on",
        
    },}

Answer 4

you can copy and past this code:

, "codeCellConfig":{ "lineWrap": "on"
}

in this path in your PC :

Users\pcname.jupyter\lab\user-settings@jupyterlab\notebook-extension\tracker.jupyterlab-settings

also you should restart your Jupyter

just this :)
