Steps to Reproduce:

1. Search for the "Configure language specific settings" command by pressing Ctrl+Shift+P
2. Select any language
3. In the configuration specific to that language, paste the line "files.autoSave": "afterDelay"
4. VSCode reports "Unknown editor configuration setting", but the global setting for "files.autoSave" works

Reproduces without extensions: Yes

Similar to #39051. Currently "files.autoSave" is not a supported language specific setting

I was just going to open the same issue. In my case, I'm finding it hard to configure VSCode for both JavaScript and Go development. For Go, files.autoSave is nice. For JavaScript, files.autoSave wreaks havoc with HMR or other bundle on change tools.

[tschaub]

Can anyone provide guidance on how someone might fix this? Is there a commit or merge request that implements something similar that could be used as a starting point?

[tschaub]

I see where overridable: true could be added to the files.autoSave (and autoSaveDelay) configuration: https://github.com/Microsoft/vscode/blob/7e7961895c6c940365bfc4bbf2287a8b8c851195/src/vs/workbench/contrib/files/browser/files.contribution.ts#L282-L293

Then it looks like overrides would need to be provided when getting the configuration: https://github.com/Microsoft/vscode/blob/7e7961895c6c940365bfc4bbf2287a8b8c851195/src/vs/workbench/services/textfile/common/textFileService.ts#L96

Maybe this override would look like

{overrideIdentifier: model.getLanguageIdentifier().language, resource}

But I'm uncertain what model and resource would be in this context. I also have no idea how this would impact other configuration and am uncertain how folder overrides are handled. And it looks like there are a few other places where the files.autoSave configuration is accessed that would need updating.

Any suggestions from vscode contributors on whether this is the right direction? I imagine there are complications, but would be happy to get something started unless this is something that is not easily achievable with the way this configuration is handled.

@tschaub I came to the same conclusion as you. Setting overridable: true where you suggested did indeed remove the "Unknown editor configuration setting" error in the settings.json file. But I couldn't figure out how to actually apply the settings.

I was testing this with a workspace, so that might be yet another variable here. I really want to have control over what files are auto saved. I have a workspace that has 2 project folders, one for api and one for front end. I suspect that many others do as well, this would be a great enhancement to Code.

Any guidance or insights you can offer us @bpasero?

It can be usefull for some sort of virtual FileSystemProviders when writeFile operation is very expensive.

[tschaub]

Adding a reference to #82101 (allowing files.eol to be set per-language) in case there are things to crib from in that change.

This problem also bothers me. Expect to be resolved.

Missing Feature autosave just for current open directory file.

vote vote vote!

[desmondlzy]

Yeah, I feel this feature could be really helpful to me!

Autosaving for source code is nice, but when editing latex file with 'compile upon save', frequent save can keep on invoking the compiler and let error messages flood in... I deal with it by toggling autosave or set up a workspace config, neither of which is really neat. So I would really love it if we can config autosave for different file types!

[tusharsadhwani]

Bump.
Really need autosave for python (as of now), but for nothing else. It's annoying to keep toggling that setting.

[whitecolor]

Such improvements may be waited for years. Probably some custom extension is needed.
