Feature request: Call Hierarchy

[svenefftinge]

A call hierarchy of a function invocation is a very useful tool to quickly navigate in code. In VSCode I find my self using "Find Reference" repeatedly to do what I do with a call hierarchy in IDEs (Eclipse, IntelliJ).

UI-wise I think it could fit nicely with how "Find References" is done, but of course we would need to have a tree on the right hand side and the labels need to display the reference containing function definitions.

Conceptually it is close to a type hierarchy, which is requested in #15533.

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.

This feature is really necessary for people like me who need to browse source code of multiple open source projects.

It would be super beneficial especially for users coming from eclipse,intellij background.

Hualet Wang (@hualet) sandipanbiswas FYI we ignore comments in the sprit of "+1", "me too", "This is needed" etc but go for up votes (:+1:) on the descriptions of this item. Please refrain from adding these comments because it generates a lot of noise to the project and we spend time reading these comments instead of getting actual coding work done. Thanks

Johannes Rieken (@jrieken) Have you had any progress on this?

For those in interested in this, I think we can stop asking for news on this for a while as I found this comment from 2018-08-06:
microsoft/vscode-cpptools#16 (comment)

No news. We haven't started working on this yet. We plan to implement IntelliSense-based Go to Definition and Find All References before a Call Hierarchy, all of which requires implementing a multi-translation unit IntelliSense (our currently one is only one translation unit at a time).

EDIT: as per Sven Efftinge (@svenefftinge)'s reply, the above comment might only be related to the c/c++ extension.

[svenefftinge]

Tobias Hernstig (@thernstig) I think that comment is related to the c/c++ extension not generally to VS Code.

I need it desperately now - call graph or call hierarchy!

[Alex-EEE]

I agree, this is desperately needed

There now is a PR for this for the LSP
