Ecode

This application is terminal(shell gui) and text editor.

There are same name editor gainning a lot of stars. but this editor and terminal just one star from me. Hahaha.

The development of this application is very early stage now.

Purpose

I want to use CLI and small editor in a pane. I've not edited at all. I always go and back between several windows in which CLI runs. Maybe such application exists, but I started the development. it was hard even using AI CLIs.

Talk to AI, edit code, run commands — all in one fast native Windows app.

Minimal, No Electron. No webView. No 500MB install.

Process-bounded architecture: Plugins like the terminal run as separate child processes, not as in-process DLLs or web views. Each dies cleanly when closed. No process hikes or memory leaks.

	Ecode	VS Code	Neovim + terminal	Notepad++
Architecture	Native Win32	Electron	TUI editor	Native Win32
Terminal integrated	Yes (process-bounded)	Yes (Electron)	Uses host terminal	No
Editor + Terminal in one window	Yes	Yes	No (two windows)	No
Click file paths in terminal	Yes (OSC 8)	No	No	N/A
CLI command launcher	Built-in	Tasks/scripts	Shell aliases	No

Why Ecode for AI CLI

A terminal alone is not enough. AI coding tools (Claude Code, OpenCode, etc.) produce output with file paths, code snippets, and long conversations. You need to act on that output — not just read it.

With just a terminal	With Ecode
AI says "edit line 42 in main.c" → you open a separate editor, find the file, scroll to the line	Click the file path in terminal output → it opens in the editor at the right line
AI outputs a code block → you select, copy, switch windows, paste, save	Select in terminal, paste into editor tab beside it
Long AI conversation scrolls off screen → lost forever	Shift+PageUp to browse history
Type the same build/test commands over and over	Save them as CLI entries, run from a menu
Heavy Electron editor takes 5+ seconds to start and 500MB RAM	Starts in <1 second, uses <20MB RAM

What you get

• Terminal + Editor in one window: Run claude or opencode while editing files right next to it — no alt-tabbing
• Click file paths in AI output: OSC 8 hyperlinks render as clickable paths — one click opens the file
• Copy-paste between AI and code: AI proposes a change → select in terminal → paste into editor → save
• Scrollable history: Shift+PageUp/Down through AI conversations — nothing gets lost
• CLI launcher: Save frequently used commands (build, test, deploy) with names and directories
• Snappy and lightweight: Native Win32 app, <1s startup, <20MB RAM, no background processes

LocalMsg — Cross-Agent Messaging

LocalMsg is a built-in plugin that lets AI agents (Claude Code, Codex, Gemini CLI, OpenCode) send messages and files to each other on the same machine or across the LAN. It acts as a primitive message bus for agent-to-agent communication.

Key capabilities:

• REST API on 127.0.0.1:2426 — agents interact via JSON HTTP
• IPMsg protocol (UDP 2425) — interoperates with legacy LAN messenger clients
• LocalSend protocol (HTTPS 53317) — file transfers and large messages (>1KB)
• Pseudo-user routing — each agent registers a name; messages addressed by name
• File inbox — files auto-accepted for known agents, stored in %USERPROFILE%/Downloads/
• CLI tool — localmsg-cli.exe for scripting by AI agents

Features at a Glance

Terminal (Process-Bounded)

A real terminal runs as a child process inside an editor tab. Works with any CLI tool.

• Stream AI tool output in real time
• Click on file paths and URLs in AI output (OSC 8 hyperlinks)
• Browse scrollback history with mouse wheel or Shift+PageUp/Down
• Copy text from terminal output and paste into your code
• Colors, bold, italic, underline — everything renders correctly

CLI Command Launcher

Save your most-used shell commands with names and working directories. Run them from a menu anytime.

Example	Command	Directory
Build	cmake --build .	D:\project\build
Test	pytest tests/	D:\project
Git status	git status	D:\project
AI chat	claude	D:\project

Git-Friendly

• Atomic saves (write to temp, rename) — no corrupted files even on crash
• Handles huge files instantly (memory-mapped I/O)

Find in Files (Grep)

Search across your project with pattern matching, extension filtering, and regex support. Results appear in a dedicated buffer with clickable file paths.

Scriptable (optional)

JavaScript engine built in. Create macros, automate editing tasks, add custom key bindings. Not required for day-to-day AI CLI use.
