To run Neovim on Windows, you can either use the terminal Neovim or use a GUI for Neovim. If you use terminal Nvim, you may encounter various annoying issues. Based on my experience, I recommend you using a GUI client for Nvim instead of the terminal one.
Nvim-qt is one of the many GUI front end for Neovim, and it is packaged with Neovim by default on Windows platform. In this post, I will give a summary on how to solve a few issues with Nvim-qt.
Nvim-qt will use your Nvim configurations as well as a GUI configuration
file1. The GUI config file is named ginit.vim, and you should put it under
the same directory as init.vim. The directory is something like
C:\Users\Administrator\AppData\Local\nvim on Windows. If you are inside
Neovim, you can also use the command :echo stdpath('config') to show the
exact directory.
Since nvim-qt has its own options, it will get confused if you simply provide
it with nvim startup options. You need to specify nvim options after --. For
example, to open a file using specific
configuration, use the following command:
nvim-qt some_file.txt -- -u init.vimIn Nvim-qt, when we press Shift+Insert in insert mode, it
will add a literal <S-Insert>, instead of placing the text on the system
clipboard to the cursor position. To fix this issue, we can use the following
mapping:
inoremap <silent> <S-Insert> <C-R>+Nvim-qt has also provided a list of its own command to configure its behaviors. I list some of the settings in the following sections.
You can change the font Nvim-qt uses by default. To check the default font
used, use GuiFont command without argument inside nvim-qt. On my system, the
output is Consolas:h11.
According to nvim-qt documentation, the following attributes for fonts are available:
hXX - height is XX in points
b - bold weight
l - light weight
i - italicYou can chain different attribute with : character. For example, to use font
Hack in 10 point and light weight, use the
following command:
After issuing the above command, you may see the following warning message:
Warning: Font “Hack” reports bad fixed pitch metrics.
To suppress this message, use the bang version of GuiFont command instead:
The GUI tabline of nvim-qt is ugly. We can use GuiTabline 0 inside
ginit.vim to disable GUI tabline and use the TUI tabline.
Although we have set GuiTabline 0 in ginit.vim, but it seems that it is
still not disabled completely. If you open up a file with nvim-qt, the GUI
tabline appears and then disappears quickly.
To disable it completely, i.e., not showing at all, there are two ways
currently. One way is to use the --no-ext-tabline option when invoking
nvim-qt:
The second way is to edit the Windows registry for nvim-qt. Go to
Computer\HKEY_CURRENT_USER\Software\nvim-qt\nvim-qt and add a new String Value. The Name field should be ext_tabline and the Data field should be
false. Then the GUI tabline should disappear completely.
The GUI completion menu is also ugly and too long, since it shows the detailed docstrings of object methods (see image below).
You can disable it by adding the following setting in ginit.vim:
You can use command GuiLinespace to control the line space in nvim-qt, for
example, GuiLinespace 1.
Add the following settings to your ginit.vim file:
call GuiWindowMaximized(1)According to this issue, currently, it is not possible to change the cursor position color in nvim-qt. Nvim-qt just sets the cursor to the reverse of background color.
My complete configurations for Neovim can be found in my GitHub repo. For How to configure Neovim for Python development, see this post.
