Nvim On Windows Mysteriously Overrides Set Fileformat=unix
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 mysteriously overridden, resulting in files being created with the fileformat=dos setting. This issue can be particularly puzzling, especially when you have explicitly set the fileformat option in your configuration file. In this article, we will delve into the possible causes of this issue and explore solutions to 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 init.vim file and the default settings of Neovim on Windows.
Possible Causes
There are several possible causes for this issue:
1. Windows Line Endings
Windows uses a different line ending convention than Unix-based systems. By default, Windows uses the CRLF (Carriage Return + Line Feed) line ending, while Unix-based systems use the LF (Line Feed) line ending. When you create a new file on Windows, Neovim may be inheriting the CRLF line ending from the operating system, which can cause the fileformat setting to be overridden.
2. Neovim Configuration
Neovim has a complex configuration system, with multiple sources of configuration files. The init.vim file is just one of the possible sources of configuration. Other configuration files, such as the init.lua file, may be overriding the fileformat setting.
3. Windows Environment Variables
Windows environment variables can also affect the behavior of Neovim. For example, the COMSPEC environment variable can influence the behavior of Neovim's :shell command.
Solutions
To resolve this issue, you can try the following solutions:
1. Use the :set fileformat command
You can use the :set fileformat command to set the fileformat option for the current buffer. This will override the default setting and ensure that the file is created with the fileformat=unix setting.
:set fileformat=unix
2. Use the :set fileformat command in your init.vim file
You can add the :set fileformat=unix command to your init.vim file to ensure that the fileformat option is set for all new files.
set fileformat=unix
3. Use the :set fileformat command in your init.lua file
If you are using the Lua configuration file, you can add the vim.opt.fileformat = "unix" line to your init.lua file to set the fileformat option.
vim.opt.fileformat = "unix"
4. Use the :set fileformat command in your nvimrc file
If you are using the nvimrc file, you can add the set fileformat=unix line to your nvimrc file to set the fileformat option.
set fileformat=unix
5. Check your Windows environment variables
You can check your Windows environment variables to see if any of them are affecting the behavior of Neovim. You can do this by running the set command in the Command Prompt.

Conclusion
The nvim on Windows mysteriously overrides set fileformat=unixissue can be caused by a combination of factors, including Windows line endings, Neovim configuration, and Windows environment variables. By trying the solutions outlined in this article, you should be able to resolve this issue and ensure that your files are created with thefileformat=unix` setting.
