Testing fresh nvim installs can be a pain, and hard to di without borking your known good install. I've been using NVIM_APPNAME to run a test nvim in a sandbox that wont bork my main install. This usually runs for me in under a minute, can be down under 15s if I remove some of the TreeSitter installs at the end. This beats a full docker build of my full devtainer to test out nvim packaging woes.


rm ~/.cache/wwtest -rf
rm ~/.local/share/wwtest -rf
rm ~/.config/wwtest -rf
cp -r nvim/.config/nvim/ ~/.config/wwtest
NVIM_APPNAME=wwtest nvim --headless "+Lazy sync" +qa
NVIM_APPNAME=wwtest nvim --headless "+TSUpdateSync" "+sleep 5000m" +qa
NVIM_APPNAME=wwtest nvim --headless "+MasonUpdate" +qa
NVIM_APPNAME=wwtest nvim --headless "+TSInstallSync! c cpp go lua python rust tsx javascript typescript vimdoc vim bash yaml toml vue just" +qa
NVIM_APPNAME=wwtest nvim --headless "+MasonInstall lua-language-server rustywind ruff ruff-lsp html-lsp typescript-language-server beautysh fixjson isort markdownlint stylua yamlfmt python-lsp-server" +qa
NVIM_APPNAME=wwtest nvim

I've started to use this as a just recipe to run before deploying a new version of my dotfiles. So far its pairing nicely with nvim-manager
