Feature request: Show class inheritance and member overrides indicator

[markvandenbrink]

Hi @basarat,

I discovered your UML class diagram feature in ALM (really nice!) and since it can show the base class which it extends it reminded me to an "old" feature request/discussion in the atom-typescript project (see TypeStrong/atom-typescript#464).

Wouldn't it be great if you can show an indicator in the left margin of the code editor for class inheritance and member overrides (possibly with a jump to declaration on click). Just like Visual Studio does for languages like C++, C#, etc. I think it would be very useful to see a visual clue...

Big thanks for all your hard work for the TypeScript community as a whole and your efforts in creating the best TypeScript IDE! Really appreciate it.

I've done it for does this override any parent as I could do that performantly quite easily (only requires current file analysis). That provides sufficient value (at least you know if you've mistyped something).

The "is this member overridden by anything* is a bigger task in terms of its performance impact (all classes need to be analyzed) and I will think about that more.

Released with 0.0.75 🌹

Wow, very nice!!! I think the "does this override any parent" is the most useful indicator. So this is great for now. Do you think this feature could be easily integrated in atom-typescript as well (I understand your main focus is now on ALM, but I'm just curious)? Or is it hard to show custom indicators in Atom?

I noticed one small bug regarding the position of the indicator. If a member is preceded by a comment block, the indicator is displayed at the beginning of the comment block instead of the member declaration.

Its just as easy https://basarat.gitbooks.io/alm/content/contributing/why.html 🌹
