Automatically restore winfixwidth when leaving the buffer

[lambdalisue]

Close #512

Summary by CodeRabbit

• New Features
  • Enhanced window width management when switching between buffers
• Bug Fixes
  • Improved handling of window width settings during buffer transitions

[coderabbitai]

Walkthrough

The changes modify the autoload/fern/internal/drawer/auto_winfixwidth.vim file to introduce a new function s:restore_winfixwidth(). This function is added to an autocmd for the BufWinLeave event, which sets the local window option winfixwidth back to 0 when leaving a buffer. The modification aims to enhance window width management during buffer transitions, potentially addressing window-related behaviors in the Fern file explorer plugin.

Changes

File	Change Summary
autoload/fern/internal/drawer/auto_winfixwidth.vim	Added s:restore_winfixwidth() function to handle BufWinLeave event and reset winfixwidth

Assessment against linked issues

Objective	Addressed	Explanation
Fix window selector functionality after file removal [#512]	❓	Unable to definitively confirm if this change directly addresses the window selector issue without more context

Poem

🐰 A rabbit's tale of window width's dance,
Winfixwidth shifts with each buffer's glance,
Autocmd whispers, "Reset and be free!"
Restoring windows with vim-like glee,
A magical fix, both subtle and bright! 🌟

Note: The changes seem tangentially related to the reported issue, but without more comprehensive context, it's difficult to determine if they fully resolve the window selector functionality problem described in issue #512.

16-19: Consider consolidated naming convention for internal functions.
You introduced one function named s:restore_winfixwidth(), while an existing function is named s:set_winfixwidth(). They are consistent and well-named. Just ensure this naming pattern remains uniform across the plugin to avoid confusion.

---

9-9: Ensure consistency with existing event handling.
The newly added autocmd to restore winfixwidth upon BufWinLeave effectively resolves potential issues when leaving the buffer. Ensure that there are no conflicting autocmds or subsequent event triggers that might override this setting in other parts of the codebase.

To confirm that this function is not overwritten by other autocmds, we can search for other calls to autocmd BufWinLeave for this plugin:

✅ Verification successful

The BufWinLeave autocmd implementation is correct and consistent
The buffer-local autocmd works in tandem with the existing BufEnter event and follows the plugin's window management patterns. The implementation is properly scoped and can be disabled via g:fern#disable_drawer_auto_winfixwidth if needed.

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
