my-grid

my-grid

A spatial canvas editor for your terminal. Think vim meets infinite whiteboard, with live terminal zones and system monitoring built in.

"Navigate to information, don't open windows." – Inspired by Jef Raskin's The Humane Interface

Why my-grid?

Traditional terminals are linear. my-grid gives you infinite 2D space where you can:

• ✏️ Draw and diagram directly in ASCII
• 📊 Embed live terminals (PTY zones) anywhere on the canvas
• 🔄 Monitor commands that auto-refresh (watch zones)
• 🗺️ Spatially organize your development workspace
• 🚀 Navigate like vim with bookmarks and modal editing

Perfect for:

• DevOps dashboards (disk usage, logs, git status in one spatial view)
• System administration (live terminals + monitoring + notes)
• ASCII art and diagramming
• Spatial note-taking and documentation
• Terminal-native project workspaces

🎯 Core Features

Infinite Canvas

• Sparse storage – Only stores non-empty cells, unlimited space
• Configurable origin – Y-up (mathematical) or Y-down (screen) coordinates
• Grid overlay – Major/minor grid lines for alignment

Vim-Style Navigation

• Modal editing – NAV, EDIT, PAN, COMMAND, VISUAL, DRAW modes
• Bookmarks – Quick jump with m/' + 36 slots (a-z, 0-9)
• Fast movement – WASD for 10x speed

Dynamic Zones (The Killer Feature)

Zone Type	Description	Use Case
PIPE	One-shot command output	tree, ls, snapshot data
WATCH	Auto-refreshing commands	git status, df -h, monitoring
PTY	Live interactive terminal	Full shell, Python REPL, vim
FIFO	Named pipe listener (Unix)	External process communication
SOCKET	TCP port listener	Remote control, API integration

Example: DevOps Dashboard

:zone watch DISK 40 10 30s df -h
:zone watch GIT 50 15 5s git status --short
:zone pty TERM 80 24
:zone create NOTES 0 0 40 20

Layouts (Workspace Templates)

• Save/load zone configurations
• Pre-built layouts: devops, development, monitoring
• YAML format – Easy to share and version control

Visual Selection & Drawing

• Visual mode – Select rectangular regions, yank/delete/fill
• Draw mode – Trace lines with box-drawing characters
• Box tools – Integrate boxes, figlet for ASCII art
