Call hierarchy

[csholmq]

Perhaps the inverse to #15; to be able to view an entire call hierarchy of a function.

Seen it implemented in Eclipse.

Having this feature would be awesome!
In Eclipse it also works for class fields, enum constants and global variables (showing functions they're used in, and expanding the function call hierarchy from there). To be better than Eclipse, making it work for macros as well would be extra cool :)

It's really invaluable to understand and navigate non-small code bases.

Visual Studio has this, but VS Code doesn't currently have any interface to enable a call hierarchy (other than possibly some unusual interface involving repeated dropdown popups). Maybe someone could file a feature request with VS Code to enable this, if it's not already been requested? This would require the IntelliSense engine from our end. It's not on our radar to implement this yet though (Find All References would be higher priority).

Adding my vote to this one. This would be my number 1 most important missing feature and use it daily in eclipse to navigate and understand the structure of a large code base. I can live without find all references feature and use global text search with whole word option instead.

See microsoft/vscode#16110 .

A new tree view api has been added to vscode. So, this should be doable now.

Looks like https://code.visualstudio.com/docs/extensionAPI/vscode-api#TreeDataProvider .

Can I vote twice for this one? The well implemented call hierarchy is the main reason eclipse is still my go-to IDE as its an invaluable tool to navigate 1M+ LOC code bases.

Awesome feature to have! Right there on the top of bucket list..

+1 for having this useful feature integrated soon
