AppImages on WSL2

This is a reminder to self, for those times when you just gotta have vim and fishdots on a recent version of fish shell (and someone upstream has completely screwed up the CA certificates so you can’t use apt or linuxbrew because they can’t be configured to relax cacert security).

First, create a place for them to live

mkdir -p ~/bin; cd /tmp

Now get fish shell

wget --no-check-certificate https://download.opensuse.org/repositories/shells:/fish:/nightly:/master/AppImage/fish-latest-x86_64.AppImage
chmod a+x fish-latest-x86_64.AppImage
./fish-latest-x86_64.AppImage --appimage-extract
mv ./squashfs-root/ ~/bin/fish_root
abbr -a fish ~/bin/fish_root/AppRun

Then download neovim

wget --no-check-certificate 
https://github.com/neovim/neovim/releases/download/v0.4.3/nvim.appimage
chmod u+x nvim.appimage
./nvim.appimage --appimage-extract
mv ./squashfs-root/ ~/bin/nvim_root
abbr -a nvim ~/bin/nvim_root/AppRun

Lovely. Now you have the one true shell and the one true editor. All’s well with the world.
