I’ve been using the Neovim nightly build for some time. The way I have been accomplishing this is to update my local clone of the Neovim repository, and then make and install the application. This works, but it does take a little time.
With asdf and the neovim plugin I can easily update to the latest nightly version.
To add the neovim plugin to asdf
asdf plugin add neovim
To install the nightly build of neovim
asdf install neovim nightly
To make the nightly version the global default
asdf global neovim nightly
In order to update the nightly version you need to remove the old nightly version first, so I have this bash alias setup.
alias update-nvim='asdf uninstall neovim nightly && asdf install neovim nightly'
And, since asdf will let me have multiple version of Neovim installed, I could have the stable
version on hand, and use it for a project if I wanted to.
