Feature Request: Conditional Breakpoints

还没有人认领这个 Issue。

For efficient debugging, I very often need to have a break-point trigger only under certain circumstances.

Consider the following setup

here I may for example only wish for the break point to trigger if

"advanced" in case.tags

holds.

Currently, I can achieve this, but only by rewriting the code as a workaround:

The workaround is clearly clumsy, esp. as it means injecting code into ones codebase, which is en par with adding print statements everywhere.

What would be much more ideal would be one could simply add dynamic trigger-conditions to the break points.[^trigger]

For example in the UI would could add a right-click menu to the individual break points > add conditions > user entry of boolean expression:

Here one could consider the cases

checkbox	trigger condition	behaviour
☐	*	never triggers
✅	(empty)	always triggers
✅	cannot be evaluated	never triggers
✅	can be evaluated and evaluates to `true`	triggers in the given instance
✅	can be evaluated and evaluates to `false`	does not trigger in the given instance

[^trigger]: currently they can only statically be toggled.
