cosyterm 0.5.0

Your terminal, but make it cozy. One command to install a curated, Catppuccin-themed dev setup — Ghostty, Starship, eza, tmux, NeoVim, and more.

cosyTerm

Your whole terminal stack, themed in one command.
_{Ghostty, your shell, Starship, eza, tmux, NeoVim — all Catppuccin Mocha, fully reversible.}

Install

pip install cosyterm
cosyterm

Launches an interactive wizard. Pick which tools to install, choose your font and shell, then review every shell command that will run before a single thing happens. One final Enter executes the whole plan. About two minutes. Existing configs are moved to a timestamped backup first, so cosyterm restore --latest reverses the whole run.

Prefer the old step-by-step prompts (or running in a non-TTY environment like CI)? cosyterm --classic.

What you get

Tool	What it does
Nerd Font	10 patched fonts — JetBrains Mono, Commit Mono, Cascadia Code, and more
Ghostty	GPU-accelerated terminal emulator by Mitchell Hashimoto
Fish or Zsh	Fish (recommended) or Zsh (POSIX-compatible)
Starship	Cross-shell prompt — git, language versions, right-aligned and clean
eza	ls with icons, colors, git status, and tree views
tmux	Terminal multiplexer with pastel status bar at top
NeoVim + LazyVim	IDE-grade editor, pre-configured, zero setup

Changing your font

Pick any of the 10 bundled Nerd Fonts at install time, or switch later.

Switch to a different bundled font

cosyterm install font

Re-runs just the font step. Select a new one from the menu; cosyterm installs it and rewrites the font-family line in ~/.config/ghostty/config automatically. Restart Ghostty to pick it up.

Use a font you installed yourself

Edit ~/.config/ghostty/config and change the font-family line to your font's family name (the same string Ghostty expects — e.g. font-family = MyFont Nerd Font Mono). Restart Ghostty.

Docs

• Safety model — every command that runs, every URL fetched, every sudo — plus backups and blast-radius guarantees.
• Recovery — cosyterm doctor, cosyterm restore, and the --dry-run preview.
• Automation — scripted installs (COSYTERM_YES=1, COSYTERM_NVIM_CHOICE), re-running a single step, and the Python API.
• Design philosophy — why cosyTerm is opinionated and what it won't add.

Try it. If it's not for you, cosyterm restore --latest puts everything back.
