Troubleshooting Vim Issues on Bash in Windows 10

If you’re encountering issues while running Vim with Vundle on Bash in Windows 10, such as the “Unknown Command ^M” error, NERDTree problems, mouse dragging not working, or font issues, this guide will help you troubleshoot and resolve these issues.

1. Fixing the “Unknown Command ^M” Error

The “Unknown Command ^M” error is often caused by inconsistent line endings in your Vim files. To resolve this issue, you can configure Git to use consistent line endings.

1

git config --global core.autocrlf input

This command configures Git to use LF (Unix-style) line endings when checking out files.

2. NERDTree Can’t Expand Folder and Weird Icons

If NERDTree isn’t working as expected and you see weird icons, ensure that your .vimrc file is correctly configured. Make sure you have the following settings:

1
2
3
4

.vimrc
...
set encoding=utf-8
...

This setting helps with proper character encoding, which may resolve the icon display issue.

3. Mouse Can’t Drag Split Windows

If you’re unable to drag split windows with the mouse, you can enable mouse support in Vim by adding the following lines to your .vimrc:

1
2
3
4
5

.vimrc
...
set mouse=a
set ttymouse=xterm2
...

These settings enable mouse support within Vim and should allow you to drag split windows with the mouse.

4. Setting Font to Consolas

To set the font to Consolas in the Command Prompt, you need to modify the Command Prompt settings. Here’s how you can do it:

1. Open the Command Prompt.

2. Right-click on the title bar and select “Properties.”

3. In the “Font” tab, select “Consolas” from the list of fonts.

4. Click “OK” to save the changes.

5. Unlinking Homebrew Formulae

The command you provided unlinks all installed Homebrew formulae. Be cautious with this command, as it can have unintended consequences. Ensure that you understand the implications before running it. If you want to unlink a specific formula, you can replace $line with the name of the formula you want to unlink.

1

brew list -1 | while read line; do brew unlink $line; done

This command reads the list of installed formulae and unlinks each one.

By following these troubleshooting steps and ensuring your Vim and Bash configurations are set correctly, you should be able to resolve the issues you’re experiencing while using Vim with Vundle on Bash in Windows 10.
