eglot-cthier.el --- show call hierarchy with Eglot (formally called eglot-hierarchy)

[Harald Kirsch]

This shows a call hierarchy as a foldable tree, unfolded on demand.

Through nice feedback here, on codeberg and on @HaraldKi@nrw.social, it
got a significant update with bug fixes, enhancements and code improvements.

I test this with eglipse-jdts (Java) and tsc (TypeScript).

Feedback welcome.

Good work Harald, patient to see what others may have to say here.

Major improvement, thanks Harald!

I have only one minor wish: could you bind TAB like RET? I think things
like profiler-report do that, too.

Any plans for the other direction, i.e. functions called from another
function?

Thanks Harald, love it!

Seems to work with clangd too if you want to add it to the list of
supported servers. Let me know if you want me to test something
specific.

How about an option to unfold the tree by default? I was testing on a
small project, probably it gets quite bigger on large projects and
it's better to leave it folded?

Not sure if it's a clangd thing, I noticed that when I request the call
hierarchy on anything other than a function call or declaration I get a
"Error running timer: (args-out-of-range [] 0)". Maybe it could be
handled more nicely? Not sure it's something to notify the user about,
guess silently doing nothing would be fine.

Also, when I get to a leaf in the tree it shows with the '+' prefix,
when expanded it becomes '-' but there is nothing to expand so it just
changes the prefix. Maybe the leaf nodes should be made non-expandable?

Easy enough. I realize magit uses TAB too to unfold things.

Now we have incoming calls. There are also outgoing calls as well as
subtype and supertype hierarchies, all with a very similar API. I have
some code already for supertype. So ongoing. :-)

A major pain point was buffer/window/frame handling. If you want to get
creative, messing with the window/frames of the hierarchy and the source
code to see what fails would be nice.

I have no recursion-test yet. In any case I would probably add a custom
variable for the max depth to unfold initially. (Classic shift of
responsibility to the user :-) But this should not be difficult.

Hmmpf, I thought I had this fixed. But server's seem to be creative of
how to provide a null result. I'll check and may contact you again for
details or a test.

Indeed. But: nodes are only expanded on demand, so on first try, there
is no easy way around. But clearly, once known, the leaf node should be
distinguished.

Thanks! Right, Magit does that also, on sections for example. Didn't
think of that.

Will play with it a little and let you know if I find anything!

Right, I didn't think about recursion and didn't realize the tree is
built as you traverse it. A max depth limit sounds like a nice solution :-)

Thanks will follow the issues there. Feel free to contact me anytime.

Understood, for some reason in my mind all the tree was built at once
and represented as collapsed. Now current behaviour makes more sense!
