Proposal: Allow to return additional information in CompletionItem

[ko1]

Can we return additional information for users on completion with CompletionItem?

Debug adapter can know detailed information of complemented text. For example: On Ruby, if the given text is 1.time, then it returns 1.times because DAP can know 1 is Integer and it has the method Integer#times. On this case, with the completion results 1.times, showing Integer#times is informative for users. In other words, showing type information seems useful.

If the type information is short, it is enough by containing the information in label, but it's better to show them separately.

This is requesting the detail that is present in the VS Code/LSP CompletionItem:

		/**
		 * A human-readable string with additional information
		 * about this item, like type or symbol information.
		 */
		detail?: string;

I think copying that property verbatim makes sense for DAP's CompletionItems as well.

Yes, a detail property on the completionItem makes sense.

@connor4312 could you take care of getting this into the spec?

@connor4312 thanks for taking care of this.
I've moved the change log item under the previous version because I typically batch all changes under a single version per milestone.
Could you please create an adoption item in VS Code that refers to this item and explains what to do.

Ah, sorry, I didn't realize -- I already copied the change to vscode-debugadapter-node and published it as 1.53 following semver. Unpublishing is possible though somewhat dangerous -- what would you prefer I do to fix this?

[weinand]

no problem, I've reverted my commit.
