Guía completa para crear un entorno moderno de desarrollo desde terminal con IA.

📦 Stack final

Este workspace incluye:

• Terminal moderno (Ghostty)
• tmux (multiplexor de terminal)
• Claude Code CLI (AI coding agent)
• LazyGit (Git TUI)
• Yazi (File manager TUI)
• Starship prompt (prompt moderno)

Resultado:

tmux session "dev"

Window 1: AIDev
 ├─ Claude Code
 └─ LazyGit

Window 2: Files
 └─ Yazi (con archivos ocultos)

Window 3: Terminal
 └─ Shell normal

1️⃣ Instalar dependencias

Terminal Ghostty

brew install --cask ghostty

Nerd Font

brew tap homebrew/cask-fonts
brew install --cask font-jetbrains-mono-nerd-font

Configurar la fuente en Ghostty:

JetBrainsMono Nerd Font

2️⃣ Instalar herramientas base

brew install tmux lazygit starship
brew install yazi ffmpeg p7zip jq poppler fd ripgrep fzf zoxide

Claude Code:

npm install -g @anthropic-ai/claude-code
claude login

3️⃣ Configurar ZSH + Starship

Editar .zshrc:

eval "$(starship init zsh)"

Crear config:

mkdir -p ~/.config
nano ~/.config/starship.toml

add_newline = true

[character]
success_symbol = "[➜](bold green)"

[nodejs]
symbol = "⬢ "

[git_branch]
symbol = "🌱 "

[directory]
style = "bold cyan"

4️⃣ Configuración PRO de tmux

Crear:

nano ~/.tmux.conf

unbind C-b
set -g prefix C-a
bind C-a send-prefix

set -g mouse on
set -g base-index 1
setw -g pane-base-index 1
set -g history-limit 100000

bind | split-window -h
bind - split-window -v

bind -n M-Left  select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up    select-pane -U
bind -n M-Down  select-pane -D

bind -n M-S-Left  resize-pane -L 5
bind -n M-S-Right resize-pane -R 5
bind -n M-S-Up    resize-pane -U 5
bind -n M-S-Down  resize-pane -D 5

set -g default-terminal "tmux-256color"
set -ga terminal-overrides ",xterm-256color:Tc"
set -g allow-passthrough on

Aplicar:

tmux source ~/.tmux.conf

5️⃣ Configurar Yazi para mostrar archivos ocultos

mkdir -p ~/.config/yazi
nano ~/.config/yazi/yazi.toml

[manager]
show_hidden = true

6️⃣ Script automático de entorno DEV

mkdir -p ~/scripts
nano ~/scripts/dev

#!/bin/bash

SESSION="dev"

if ! tmux has-session -t $SESSION 2>/dev/null; then
  tmux new-session -d -s $SESSION -n AIDev
  tmux split-window -h -t $SESSION:1

  tmux send-keys -t $SESSION:1.1 "claude --dangerously-skip-permissions" C-m
  tmux send-keys -t $SESSION:1.2 "lazygit" C-m

  tmux select-layout -t $SESSION:1 even-horizontal

  tmux new-window -t $SESSION:2 -n Files
  tmux send-keys -t $SESSION:2 "yazi" C-m

  tmux new-window -t $SESSION:3 -n Terminal
fi

tmux select-window -t $SESSION:1
tmux attach -t $SESSION

Permisos:

chmod +x ~/scripts/dev

Alias:

alias dev="~/scripts/dev"

7️⃣ Uso diario

Iniciar entorno:

cd tu-proyecto
dev

Cerrar tmux:

tmux kill-server
