Sourcetrail On-demand control flow diagrams for functions

[New feature] Any plans to add in the future automatic creation of visual control flow for any method / function, similar to what understand is doing?

Are you referring to the control flow within a method / function?

yes, I like it for average size function, when it is still readable and useful (especially to diff with previous version). But I know this would be complex to develop.

Yes, it would be complex to develop and also require a lot more data to collect and store.

I was thinking more of a 'on-demand functionality' ... when inside a function, could do - right-click / generate control flow for the current function - to switch to a graphical view. I don't think cross-references are required here because we focus only on the current function. Clicking on an item in the graph would bring us back to the corresponding line of code in the function. Not sure if this make any sense ...

I agree that this would be a very useful functionality!

This would be extremely helpful. I think that LLVM is able to provide a CFG for any function.

Here is an old blog post about this idea. The API has probably changed in the meantime...

Edit: Ah, sorry. This would be only related to LLVM-IR it seems, not for high-level C.
