Introduction

As a user of Neovim on Windows, you may have encountered a frustrating issue where the set fileformat=unix configuration in your init.vim file is being overridden, resulting in files being created with the fileformat=dos setting. This issue can be particularly puzzling, especially when you have explicitly set the file format to Unix in your configuration file. In this article, we will delve into the possible causes of this issue and provide solutions to help you resolve it.

Understanding the Issue

When you run nvim new.txt on Windows, the file is created with the fileformat=dos setting, despite your init.vim file containing the line set fileformat=unix. This suggests that there is a conflict between the configuration settings in your init.vim file and the default settings used by Neovim on Windows.

Possible Causes

There are several possible causes for this issue:

Default settings: Neovim on Windows may have default settings that override the fileformat=unix setting in your init.vim file.
Windows-specific settings: Windows may have its own settings that affect the file format used by Neovim.
Conflicting plugins: Plugins used in your Neovim configuration may be overriding the fileformat=unix setting.

Solutions

To resolve this issue, you can try the following solutions:

1. Check the Neovim configuration file

First, check your init.vim file to ensure that the set fileformat=unix line is present and not commented out. You can do this by running :edit $MYVIMRC in Neovim.

2. Disable Windows-specific settings

Windows has its own settings that can affect the file format used by Neovim. To disable these settings, you can add the following line to your init.vim file:

set nobomb

This will disable the Windows-specific settings that may be overriding the fileformat=unix setting.

3. Check for conflicting plugins

Plugins used in your Neovim configuration may be overriding the fileformat=unix setting. To check for conflicting plugins, you can try disabling all plugins and then re-enabling them one by one to see if the issue persists.

4. Use the `:set` command

You can use the :set command to set the file format to Unix manually. Run the following command in Neovim:

:set fileformat=unix

This will set the file format to Unix for the current buffer.

5. Check the Neovim version

If you are using an older version of Neovim, it may have a bug that causes the fileformat=unix setting to be overridden. Try updating to the latest version of Neovim to see if the issue is resolved.

6. Check the Windows version

If you are using an older version of Windows, it may have a bug that causes the file format to be set to DOS. Try updating to the latest version of Windows to see if the issue is resolved.

Conclusion

The issue of Neovim on Windows mysteriously overriding the set fileformat=unix configuration is a frustrating one, but it can be resolved by trying the solutions outlined above. By checking the Neovim configuration file, disabling Windows-specific settings, checking for conflicting plugins, using the :set command, checking the Neovim version, and checking the Windows version, you should be able to resolve this issue and ensure that your files are created with the correct file format.

Additional Tips

Use a version control system: Using a version control system like Git can help you keep track of changes to your files and ensure that your project is consistent.
