Memos Bug: Incorrect Checkbox Behavior in Code Blocks

Hey guys! Let's dive into a quirky bug spotted in Memos that might be messing with your checklists. It's all about how checkboxes behave when they're hanging out inside code blocks. So, if you've noticed some weirdness with your checkboxes, you're not alone!

The Issue: Checkboxes Gone Wild

Essentially, the problem arises when you have a checkbox within a code block and another one right after it in your Memos note. Clicking the second checkbox doesn't always behave as you'd expect. Instead of just toggling that specific checkbox, it sometimes seems to get confused and not register the change correctly. This can be super annoying when you're trying to keep your tasks and notes organized, right?

Steps to Reproduce

To see this bug in action, follow these simple steps:

  1. Create a new memo with the following content:

    ```
-[ ] foo
```
- [ ] bar
    • Notice that the first checkbox (foo) is inside a code block, and the second checkbox (bar) is outside.

  2. Switch to view mode in Memos.

  3. Click the bar checkbox.

Expected Behavior

What should happen is that only the bar checkbox gets checked, like this:

```
-[ ] foo
```
- [x] bar

Actual Behavior

But, in reality, the bar checkbox might not toggle correctly, or the display might not update as expected. This is definitely not what we want!

Why This Matters

You might be thinking, "Okay, it's just a checkbox. No big deal!" But think about how you use Memos. Many of us rely on checklists to manage tasks, track progress, and stay organized. When checkboxes don't work reliably, it can lead to confusion and frustration. Imagine you're using Memos for project management, and you can't trust that your checkboxes are accurate. It could throw off your entire workflow!

Technical Details

  • Memos Version: v0.25.3 (This bug was reported in this version, but it might exist in other versions as well.)
  • Client Environment:
    • Linux Mint 22.2, Chrome 142.0.7444.175 / Brave
    • Android 15, Chrome 142.0.7444.171
  • Deployment:
    • Container from official docker image
    • Official demo site

Possible Causes

While we can't say for sure what's causing this bug without digging into the Memos codebase, here are a few potential explanations:

  • Markdown Parsing Issues: The way Memos parses Markdown might be getting confused when it encounters a checkbox inside a code block followed by another checkbox. The parser might not be correctly differentiating between the two.
  • Event Handling: The event handling for checkbox clicks might not be properly isolated. When you click the bar checkbox, it might be inadvertently triggering some code related to the foo checkbox as well.
  • Rendering Problems: There could be a rendering issue in the Memos UI that's causing the checkbox state to be displayed incorrectly, even if the underlying data is correct.

How to Work Around the Issue (Temporarily)

Until this bug is officially fixed, here are a few workarounds you can try:

  • Avoid Checkboxes Immediately After Code Blocks: The simplest solution is to avoid placing checkboxes directly after code blocks. Add a line break or some other content between the code block and the checkbox.
  • Use a Different Checkbox Style: If possible, try using a different style of checkbox that might not trigger the bug. For example, you could use a simple text-based checklist instead of the built-in checkbox feature.
  • Double-Check Your Checkboxes: Always double-check that your checkboxes are in the correct state after clicking them. If you notice any discrepancies, try toggling them again.

The Importance of Reporting Bugs

It is important to report any issues you encounter while using software. By reporting bugs like this checkbox issue in Memos, you're helping the developers improve the software and make it more reliable for everyone.
