Auto-Expand Error Sections: A Marimo Feature Request
Have you ever been working on a project, meticulously crafting your code, only to be met with the dreaded red highlight indicating an error? It's a common experience for developers, and Marimo, a fantastic tool for building reactive notebooks, is no exception. Marimo's code-collapsing feature is a great way to organize your work and keep things tidy. However, a potential issue arises when these highlighted errors get tucked away within collapsed sections, effectively hiding them from immediate view. This article delves into this issue and proposes solutions to enhance the user experience in Marimo, ensuring that errors are always front and center.
The Challenge: Hidden Errors in Collapsed Sections
Marimo's code-collapsing feature is a game-changer for managing complex notebooks. It allows you to condense sections of code, making it easier to navigate and focus on specific areas. However, this feature can inadvertently conceal highlighted errors if they reside within a collapsed section. Imagine this scenario: you've collapsed a lengthy function definition, and an error occurs within that function. The red highlight, designed to draw your attention to the problem, is now hidden, potentially leading to frustration and wasted time as you try to locate the issue. This is a classic case of a feature, designed to improve usability, creating an unintended obstacle in the debugging process. The core challenge is to ensure that error highlighting remains effective even when code sections are collapsed. We need a mechanism that brings these hidden errors to the forefront, allowing developers to quickly identify and resolve them.
Proposed Solutions: Keeping Errors Visible
To address the issue of hidden errors, several solutions can be implemented. Each approach aims to provide a clear indication of errors within collapsed sections, ensuring that developers don't miss crucial information. Here are two primary solutions that could be implemented in Marimo to solve this problem:
1. Highlight the Collapsed Line in Red
One straightforward solution is to extend the error highlighting to the line that represents the collapsed section. Instead of only highlighting the line with the actual error, Marimo could also highlight the collapsed line itself in red. This would act as a visual cue, immediately alerting the user to the presence of an error within the collapsed section. Think of it as a visual breadcrumb, leading you directly to the source of the problem. This approach is simple yet effective, providing a clear and concise indication of errors without being overly intrusive. It maintains the clean look of the collapsed code while ensuring that errors don't go unnoticed. This method ensures that the user is immediately aware of the error's presence, even without expanding the section.
2. Auto-Expand Highlighted Lines
Another approach is to automatically expand any collapsed section that contains a highlighted error. This proactive solution ensures that the error is immediately visible, eliminating the need for the user to manually expand sections. When an error occurs, Marimo would automatically open the relevant section, bringing the highlighted line into view. This approach prioritizes error visibility, ensuring that developers are immediately confronted with the issue. While this method might disrupt the collapsed structure of the notebook, it guarantees that errors are never hidden. Auto-expansion ensures that errors are not only visible but also easily accessible, streamlining the debugging process.
Both solutions offer unique advantages, and the best approach might depend on the user's preferences and workflow. Perhaps a combination of both methods could be implemented, providing users with flexibility in how they want to handle error visibility in collapsed sections.

Alternatives Considered
While the proposed solutions offer direct approaches to the problem, alternative methods could also be explored. One alternative might involve a more sophisticated error reporting system, where Marimo provides a summary of errors, including their location within collapsed sections. This would offer a centralized view of all errors, regardless of their location. However, this approach might be less intuitive than the visual cues provided by highlighting or auto-expansion. Another alternative could involve user-configurable settings, allowing developers to customize how Marimo handles errors in collapsed sections. This would provide flexibility but could also add complexity to the user interface. Ultimately, the most effective solution will likely be a balance between simplicity, intuitiveness, and flexibility.
Additional Context: The Importance of Error Visibility
In software development, error visibility is paramount. Errors are inevitable, but how quickly and easily they can be identified directly impacts development time and efficiency. Hiding errors, even unintentionally, can lead to significant delays and frustration. Marimo, as a tool designed to facilitate rapid prototyping and experimentation, should prioritize error visibility. By ensuring that errors are always readily apparent, Marimo empowers developers to quickly iterate and refine their code. The proposed solutions aim to reinforce this principle, making Marimo an even more powerful and user-friendly tool.
Conclusion: Enhancing Marimo's Error Handling
The code-collapsing feature in Marimo is a valuable tool for organizing notebooks, but it presents a potential challenge in terms of error visibility. By implementing solutions such as highlighting collapsed lines or auto-expanding sections with errors, Marimo can further enhance its user experience and streamline the debugging process. The Marimo community's proactive approach to identifying and addressing such issues underscores the tool's commitment to continuous improvement. As Marimo evolves, maintaining a focus on error visibility will be crucial in ensuring that it remains a powerful and user-friendly platform for building reactive notebooks. By making errors more visible, Marimo empowers developers to write better code, faster.
