Hello,

How do I get the name of the method I'm in (perhaps with line-number) ?
(like the error-stack when failing)

thank you

*[1] pry(main)> def mymethod[1] pry(main)* [ __method__,
self.method(__method__).source_location ][1] pry(main)* end=> :mymethod[2]
pry(main)> mymethod=> [:mymethod, ["(pry)", 5]][3] pry(main)>*

Hello,

is it possible to do this it only once (metaprogramming), so that it is
done for all (my) methods starting AND ending ?

- Do I have to build the method-call stack by myself, or can I somehow
use the avalilable call-stack?

thank you

It sounds like your intention is to trace and log program execution ? ...

You most probably think about one of these methods:

https://rubyapi.org/3.0/o/kernel#method-i-caller

https://rubyapi.org/3.0/o/kernel#method-i-caller_locations

The first one returns Strings, the second one a Thread::Backtrace::Location which respond to methods like #lineno and #label which can help you achieve what I think you try to achieve.
