GuiFont doesn't exist when using a different NVIM_APPNAME environment variable

[LonelyMusicDisc]

The NVIM_APPNAME environment variable is super useful for having multiple configurations, but setting it to something other than nvim breaks the custom commands.

NVIM_APPNAME=something seems to change the expected locations used by nvim (runtimepath, etc) by append the env var value at the end of paths.

This should not be a problem when the nvim-qt vimscript is loaded by nvim-qt. I did a quick test here and it seems to work as intended.

However if you are loading the shim manually from your config (such as adding equalsraf/neovim-gui-shim as a plugin) then you could run into problems because it is using the wrong path (or configuration).

Can you check if :scriptnames shows nvim_gui_shim.vim being loaded?

The output from nvim-qt --version would also help, so we know which versions your are running.

Thank you. It doesn't appear in scriptnames and I'm not doing any manual loading

Looks pretty normal:

  args: --cmd let &rtp.=',/usr/bin/../share/nvim-qt/runtime' --cmd set termguicolors

i.e. it is expecting to find it in /usr/share/nvim-qt/runtime. Does that folder exist?
Also just in case, is there anything useful in :messages?

[LonelyMusicDisc]

The folder exists and :messages reports nothing unfortunately
