fish-shell VS powerlevel10k

I didn't realize fish was written in Rust, and it was my primary shell for a few years. Looks like they couldn't resist the rewrite it in Rust meme :-D

vs the C++

Follow this to install. Note that this tutorial assume that you are on Linux.

The most interesting thing about Fish 4.0.0 for most people will be that it is now written in Rust, which they talk about here [1]. Looking forward to testing it out and seeing if there are any noticeable differences.

I've probably been using fish shell [0] for close to 10 years now. When I need POSIX compliance or if I need to run a one-off bash command, I just call bash. It's exceedingly rare.

Browsing through the documentation for Oils, it seems to be organized in a way that's very confusing. When you open the fish shell website it was two clear buttons for Tutorial and Documentation.

I remember that Julia Evans, whose blog I follow, mentioned a few time that she uses Fish. Also, some days ago I came across this post about Fish rewrite to Rust from C++, which sounds like a cool thing to do. However, I tried it some time ago, and while pretty neat, I wasn't convinced to switch to it completely.

The default shell in the above flake adds Valkey, NodeJS 22, the PNPM package manager, and the fish shell to the environment. It also starts Valkey in the background through a shell hook, passing it a custom config (declared via Nix!) and runs fish so we're dropped in the fish shell instead of our login shell.

I’m testing a new shell called fish, and I’m enjoying some features that truly make it a friendly interactive shell.

WezTerm does not have a graphical interface for configuration, and the setup is done through a Lua file (this is unusual for me, but Vim users are familiar with it). The configuration file can be located at ~/.wezterm.lua or ~/.config/wezterm/wezterm.lua. I prefer the second path because it is where Fish and starship store configs too.

Typing repetitive commands or copying and pasting test names can eat up valuable time. To help, I've created pytest.fish - a Fish shell plugin that simplifies your pytest workflow. It's lightweight, simple to set up, and makes testing more efficient.

# 1. Backup existing configuration cp ~/.zshrc ~/.zshrc.backup 2>/dev/null || echo "No existing ~/.zshrc" # 2. Install Homebrew /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" # 3. Install iTerm2 brew install --cask iterm2 # 4. Install Oh My Zsh sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" # 5. Install Powerlevel10k theme git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k sed -i '' 's/ZSH_THEME="robbyrussell"/ZSH_THEME="powerlevel10k\/powerlevel10k"/' ~/.zshrc # 6. Install essential plugins git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting brew install autojump # 7. Restart terminal or reload configuration source ~/.zshrc

There are a lot of themes, with Powerlevel10k being the most popular and powerful. To install it, run:

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

That’s the minimum terminal setup. You can modify the look and add plugins such as autocompletion to your terminal by installing ohmyzsh and using themes such as powerlevel10k. I am already using them.

I used ohmyzsh with powerlevel10k/powerlevel10k[0] for years though recently i've settled on fish [1]

I had just gone through a fun tutorial for setting up oh-my-zsh with a nice color scheme from iterm2colorschemes.com and a decent prompt and I was wondering: can I make my oblique strategy look nice? how can you actually use the colors from your scheme in the output in your cli?

A more robust way to do this would be to add simple wrappers that clone any external Zsh plugins you use regularly and store them in your own $ZSH_CUSTOM. For example, you say you like Powerlevel10k, so make that an OMZ plugin:

Looks like PowerLevel10 theme for Zsh shell
