Issue #15287 has been updated by shevegen (Robert A. Heiler).
I love introspection, so .. \o/
----------------------------------------
Feature #15287: New TracePoint events to support loading features
https://bugs.ruby-lang.org/issues/15287#change-74786
* Author: ko1 (Koichi Sasada)
* Status: Open
* Priority: Normal
* Assignee: ko1 (Koichi Sasada)
* Target version: 2.6
----------------------------------------
# Abstract
I propose the following new TracePoint events:
* `loaded` (invoked after `require`/`load`)
* `method_added` (invoked after method definition)
# Background
Sometimes we need to hook loading iseq. For example, checking loading files and so on.
Also we want to know what kind of methods are defined.
For both purpose, we can use some hook methods such as `Module#method_added` and so on.
However, defining methods we can override this features.
So that if we have two tools/libraries using this feature, they can be conflicted.
# Proposal
Introduce new TracePoint events:
* `loaded` (invoked after `require`/`load`)
* `method_added` (invoked after method definition)
Also the following methods can be added:
* Active only `loaded` event:
* `TracePoint#loaded_feature` returns feature name.
* `TracePoint#loaded_iseq` returns `RubyVM::InstructionSequence` object (MRI only, internal feature)
# Optional proposal
Add `class_added` alias name for `class` event.
