As some of you may know, nvim-qt treats all the command line arguments it receives as the arguments for the Qt frontend. If you want to pass arguments to nvim itself, you need to write them after a -- separator.
This may cause some inconvenience, especially if you want to set nvim-qt as the default editor in your operating system.
So to solve this exact problem, you may use this wrapper program, which would forward all the command line arguments it receives to nvim-qt with the separator being put right before them.
In other words, win-nvim-qt-adapter.exe argument1 argument2 ... is equivalent to nvim-qt -- argument1 argument2 ....
Its path is found in all the folders that are specified in your system's %PATH%. If your nvim folder is not there, this adapter won't work.
You need to compile it:
clang++ -std=c++20 -O3 .\win-nvim-qt-adapter.cpp -lshell32 -lshlwapi -o win-nvim-qt-adapter.exe
This program may also be compiled with cl.exe from Microsoft, but you should figure it out yourself, because I'm not that familiar with its command line interface.
After you've compiled it, you may use it however you like! You may choose it in "Open with" dialog in Windows' file explorer, or run it using cmd.exe.
Sure, here you go:
#!/bin/sh
nvim-qt -- "$@"Save this script wherever you like, and then run chmod +x THE_FILENAME_OF_THE_SCRIPT and you may call it done.
If you select .bat script in the "Open with" dialog, the cmd.exe window will be shown up, and it won't go away until you stop working with nvim-qt, which is quite annoying.
.ps1 script cannot be chosen in "Open with" dialog, so is any other script.
Honestly, I don't know. It works on my Windows 11 machine, but I think you won't be satisfied with this answer.
Well, I think I can try. Open an issue here or something.
Sure.
