Overriding User Settings

[avneeshn]

Hi
I am using jupyterlab-lsp as a dependency in my extension. I want to change the default behaviour of following user settings (under completion.jupyterlab-settings) when the user installs my extension.

//Default behaviour currently by jupyterlab-lsp
"continuousHinting": false,

//Default behaviour when user installs my extension
"continuousHinting": true,

Is there a way I can do it in my extension?

A prebuilt extension can ship a json file in `overrides.d/` to impact another extension's defaults: jupyterlab/jupyterlab_server#224

[avneeshn]

Thanks a lot. Another follow-up question: once I change the default to true, would that automatically enable "continuousHinting" once my extension is installed?

[bollwyvl]

As a default, it would be enabled unless overridden by another extension's overrides.d/zzz-later-by-lex-sort.json. An explicit choice by the user (before or after installing an overriding extension) will prevent any default from taking effect. An extension that requires a particular setting in another extension would be encouraged to offer a message to that effect, but likely also with a way to opt-out of seeing the message ever again.

Hi bollwyvl,
I am having a hard time understanding the overrides.d/ way. As I understand, I will have to put the overriding json file in {application_dir}/overrides.d/ dir. But how do I do that? Do you have any idea?

[krassowski]

Oh, this is for overrides.d/ I guess this needs to be copied over during installation. This then depends whether you are developing a source or pre-built extension. If it is the latter, you can copy it in the install/scripts. Details depend on what tool you use for installation, but the current extension template uses hatch with some files being copied over here.

Alternatively, you can just flick the setting using SettingsRegistry. FYI, in JupyterLab 4.0 and corresponding version of the extension enabling continuousHinting got a bit weird, see jupyterlab/jupyterlab#15022

Alternatively, you can just flick the setting using SettingsRegistry.

Can you please provide any references on how to implement this? I cannot find anything in lsp docs or jupyter docs
