jpillora/installer is the install script generator I have been looking for. It downloads binaries for your machine from GitHub releases and unzips them for you. It grabs the latest release, so you can easily update them. I have tried scripting these installs in the past and struggled to consistently get the latest version for every package and unpack it correctly.
Also these pre-compiled binaries install rediculously fast compared to building them from source.
Check out some example links.

If you pass in script=true it will instead return the install script as it would by default through curl.

Use it to install neovim
All you need to do to generate an install script is to pass in the GitHub repo slug with the org.
curl https://i.jpillora.com/neovim/neovim | bash
The shell script that it generates for neovim looks like this.
#!/bin/bash if [ "$DEBUG" == "1" ]; then set -x fi TMP_DIR=$(mktemp -d -t jpillora-installer-XXXXXXXXXX) function cleanup { rm -rf $TMP_DIR > /dev/null } function fail { cleanup msg=$1 echo "============" echo "Error: $msg" 1>&2 exit 1 } function install { #settings USER="neovim" PROG="neovim" ASPROG="" MOVE="false" RELEASE="stable" INSECURE="false" OUT_DIR="$(pwd)" GH="https://github.com" #bash check [ !

Self Host Your Own
I'd reccomend self hosting your own. This way you know that it's consistent and unlikely to change in a way that breaks your use.
