研究方向

issue 中沒有指定檔案、測試或進入點。首先追蹤 Python 偵錯器如何處理中斷點狀態和評估;done 應涵蓋針對空白、無效、true 和 false 條件所列出的 UI 和行為案例。

描述

triage-needed

Motivation

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.

Current workaround

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

Proposal

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.
