☑️ Features

🫀 Core

• Plugin manager: Zi

  This is the better-maintained but less popular resurrection of zdharma/zinit, f.k.a. zdharma/zplugin.

⚡️ Performance

• Powerlevel10k Instant Prompt provides an instantly interactive prompt while zshrc is loading.

• Zi's internals and features are highly optimized for performance, especially at load time.

  • It compiles all plugins' Zsh scripts to Zsh word code ([…].zwc).

  • Zi light loading and turbo mode are employed for fast and asynchronous loading of plugins.

  • All completion files (including those installed system-wide and those generated by external tools) are managed by Zi. zicompinit_fast is employed (invoked asynchronously) so that .zcompdump is generated on compinit only once a day.

• Zsh features are employed instead of alternatives that entail subprocesses, subshells, I/O, and other slow operations.

  For example:

  • Zsh expansions and arrays are favored over forking subshells to execute head, tail, cut, grep, sed, and the like.

  • Command existence is checked/resolved via $commands (a fast hash lookup) rather than forking a subshell to execute command -v (a slow interrogation of the filesystem) or which (likewise, but with an additional program execution).

• Fetched and generated files (e.g. completions, themes) are cached and only refreshed on explicit update.

🏪 Convenience

• Useful and sensible settings for Zsh options and Zsh parameters.

• Conformance to the XDG Base Directory Specification (as much as possible) in order to provide a clean and consistent home directory layout

  • For the full effect, install my XDG Base Directory environment.d configuration in ~/.config/environment.d/.

• Zi update (zi-update, alias zup) handles all updates, including refreshing the cached instances of fetched/generated files.

• Completions for all the things:

  • Fancy completions configuration via zsh-fancy-completions

  • System-wide completions managed by Zi via system-completions

  • Additional completions via zsh-completions

  • Generated completions:

    • Python CLI apps via shtab

    • cog

    • elm via kraklin/elm.plugin.zsh

    • kdesrc-build

    • pip, pipenv, pipx

    • pnpm

    • rye

• Auto-suggestions via zsh-autosuggestions

• Multi-word history search via H-S-MW

  This is the better-maintained but less popular resurrection of zdharma/history-search-multi-word.

• Common-sense integrations:

  • Set terminal title

  • Sane paste behavior via bracketed-paste-magic

  • Automatically detect and use node_modules/.bin

• Awesome helpers:

  • Help:

    • help (alias: ?): Get help via run-help or man

    • ghcs-shell/ghcs-gh/ghcs-git (alias: ??/??gh/??git): Request a shell/gh/git command from GitHub Copilot given a natural-language description

    • sgpts/sgpt4s (alias: ???/????): Request a shell command from GPT/GPT-4 via ShellGPT given a natural-language description

  • Filesystem:

    • in-dir (alias: ind): Run the given command in the given directory

    • mkcd: Create the given directory and change into it

    • mktemp/mktempd: Create a temporary file/directory with the system's mktemp command, but use $XDG_RUNTIME_DIR as the default location

    • pprint-file (alias: pf): Pretty-print a file

    • diff-fancy (alias: d): diff --unified piped through diff-so-fancy

  • Expressiveness:

    • Enabled from the community contributions bundled with Zsh:

      • throw and catch

      • zargs

      • zmv and its siblings zcp and zln

    • Higher-order functions via zsh-functional

  • Security:

    • wrap-with-secret-from-kwallet: Wrap a command with an environment variable containing sensitive information (e.g. API key, password), retrieving the value from KWallet via kwallet-query

  • Introspection:

    • pprint-zfunc (alias: pfn): Pretty-print the source code of a Zsh function

    • realcmdname: Determine the real underlying command name invoked by a command (resolving aliases recursively, and ignoring various command prefixes)

• Global preferences:

  • vi mode

    And more, via evil-registers, vi-motions, and vi-quote

  • Pager: bat

  • man pager: Neovim

  • Editor: Neovim

  • Browser: Firefox

🦋 Visuals

• Prompt theme: Powerlevel10k

• Feature-rich syntax highlighting using F-Sy-H

  This is the better-maintained but less popular resurrection of zdharma/fast-syntax-highlighting.

• Auto-colorization of numerous commands' output via Generic Colouriser (grc)

• Auto-colorization and paging of --help output via a global alias that pipes it through bat --plain --language=help

• Catppuccin themes for all the things:

  • F-Sy-H via catppuccin/zsh-fsh

  • fzf via catppuccin/fzf

  • Glamour via catppuccin/glamour

  • Lazygit via catppuccin/lazygit

  • LS_COLORS generated with vivid using the catppuccin-mocha theme.
