Is there a way for me to implement a feature akin to the @deprecated annotation?

In my TypeScript Next.js application, I rely on Visual Studio Code for coding purposes.

One feature that I particularly enjoy is the ability to add a JSDoc annotation of @deprecated above a function, which then visually strikes through the function name to serve as a warning for all usages:

There are times when I consider marking functions as @deprecated just to ensure that users pay extra attention and read the comments before using them.

However, I hesitate to use the term "deprecated" when I have no intention of removing the function entirely.

Instead, I might want to draw attention to a better alternative by stating: "Rather than using this function, you should consider using [this other function] instead."

Is there an alternative annotation available for this purpose? If not, how could I create one?

I would like all usages to automatically change the appearance of the function name to emphasize the message (either through a strike-through or another styling option).

Answer №1

It is possible that there exists a feature like this, but as far as I know, there is no such feature. Deprecation is typically a type of status that is hardcoded. You can verify this information by referring to the extension API docs for VS Code. The same applies to the deprecation modifier in semantic highlighting.

Regarding syntax highlighting, both semantic and TextMate-based syntax highlighting in VS Code support various font styles like strikethrough, italics, bold, and underlining through the use of fontStyle modifications. You could potentially create a VS Code extension that adds a TextMate or semantic highlighting scope for your function and then define the font styling for it. It may seem a bit excessive, but it can be done.
