Hi. So I've been a fish user for a while, but I've always gotten frustrated with it not being POSIX compliant. I tried to use zsh with oh-my-zsh to still benefit from fish's capabilities on zsh, but I had 2 problems with it: it was incredibly slow, and it wasn't as good. As I recently found out, the plugins can just be sourced in zsh directly, skipping oh-my-zsh, and fixing my speed issues. But the second issue remained: zsh-autosuggestions is just not as good as fish's autocompletion feature, which suggests commands in a user's PATH, as well as autocompletes directories, without me having ever accessed them, meaning they weren't even in the history at that point, which allowed me to hit the ground running. I want that with zsh as well. Is there a plugin or something like that, which allows for these extra features, and can autosuggest commands from PATH and autocomplete directories? I really want to switch to a POSIX shell, but the lack of this feature would make it feel like quite a downgrade. Thanks.
you should be able to reconfigure the plugin, I have it set to pull from history first and after that look for standard command completion using the following:
ZSH_AUTOSUGGEST_STRATEGY=(history completion)
important is that you put this BEFORE sourcing the plugin.
the github should carry more information on how to configure this plugin.
PS: I use all of 4 plugins (fzf-tab-bin, zsh-autosuggestions, zsh-syntax-highlighting, zsh-history-substring-search) and I have a better shell in zsh than I will ever have in fish, I don't need anything more fancy and oh-my-zsh is hell to work with compared to a simple .zshrc I handrolled because it's got any other shell I know beat (yes I know of nushell and it is cool, but it's even less posix than fish).
also, once you're done run zcompile .zshrc, you won't regret it.
It worked! Thank you so much. That's all I need. I have seen people use zsh-history-substring-search and fzf-tab but I don't currently need them, so I won't use them. Once again, thank you so much.
I type in a command without sudo, I prefer to type in a sudo !! rather than to up arrow, then do Ctrl+A then type sudo and press Enter, for example. I wanted to install Nix earlier, but I needed to be in a POSIX shell for it to work, so I had to switch to bash for the installation. Those are just 2 examples from earlier today, and while you can learn to deal with them, it would juat be more effective to use a POSIX shell instead. It also means I can just set it as my login shell instead of having each of my terminal keybinds as kitty -e fish, across all of my many window manager configs. Fish is faster, but I'm not sure if the cost is worthwhile.

Fish has a hotkey for this built-in, just hit Alt + S.
The login shell troubles are very valid however. I worked around them by modifying my .bashrc to drop me into fish, and it has been working pretty well for me so far.
The linked solution also handles only launching fish if the parent process is not fish, so you can still access bash easily for when you really need it.
Okay, I LOVE this. If I ever decide to do a new zsh config, I will definitely use that. There's some pretty cool stuff in here, but I've already got everything configured pretty much the way I want it. Thanks anyways.
Literally not even slightly what you're asking for, but have you considered using bash with ble.sh? I'm also a former fish user, and ble.sh replicates all of fish's quality of life improvements (that I used, at least) and then some, all with a single source command in my .bashrc.
