• File Explorer: 紙 Kami - directory navigation, hidden-file toggle, dirs-first sort
• AI Assistant: 零 Rei - powered by hako-code in a split pane. Local hako models (sho-stock / koi-mini-stock) or any of its 13 cloud providers, function-calling tool loop, SSE streaming, per-project trust and history
• Skills: drop ~/.hako/skills/*.md into the system prompt, install from any URL with /skill install

Build

# One-liner - works on Linux, macOS, Windows (mingw)
gcc hake.c -o hake -lpthread

# Or use the Makefile to also embed the executable icon where the OS allows
make

Run

./hake              # or  ./hake [filename]

Install (drop the binary into your PATH):

cp hake /usr/local/bin/hake          # Linux / macOS

Deps: C standard library + POSIX/Win32 system headers + pthread. No third-party libraries linked. AI features shell out to curl(1) at runtime.

Install

# Curl one-liner (Linux / macOS / Windows-MinGW)
curl -fsSL https://raw.githubusercontent.com/mithraeums/hako-edit/main/install.sh | sh

Verifies sha256, installs to /usr/local/bin if writable else ~/.local/bin. macOS quarantine xattr stripped post-install. Set VERIFY=0 to skip sha verify, PREFIX=/opt to relocate.

Executable icon

The icon files live in icon/:

Platform	File	What make does
Windows	hake.ico	Embeds icon into .exe via windres; real OS icon.
macOS	hake.icns	Attaches icon as a resource fork via Rez+SetFile (Xcode CLT). Best-effort.
Linux	hake.png	ELF can't embed icons; ship hake.png and reference it from a .desktop file.

A plain gcc hake.c -o hake produces a working binary on every platform; the icon is purely cosmetic.

iSh (iOS - experimental)

hake compiles on Alpine via iSh:

apk add gcc make musl-dev curl
make

Notes:

• AI panel needs curl for HTTPS requests; apk add curl is required before using Rei.
• Narrow screens auto-stack the AI panel below the editor instead of squeezing horizontally.
• iSh runs single-threaded under emulation; expect slower stream rendering.

Configuration

Use supplied config, or generate one with :config inside the editor. HAKE looks for .hakorc in the current directory first, then your home directory.

# Example .hakorc
tab_stop=4
use_tabs=1
show_line_numbers=2
auto_indent=1
smart_indent=1
mouse_enabled=1
theme=dark
explorer_width=30

# AI panel (Rei)
ai_provider=deepseek          # or anthropic | openai | ollama | mistral | ...
ai_api_key=sk-...             # not needed for ollama
ai_model=deepseek-chat
ai_max_tokens=2048
ai_tools_enabled=1
ai_stream=1
ai_autowrite=1                # 0 stages writes to <path>.hako-pending
# ai_endpoint=                # auto-set for known providers

Run :config to generate a fully documented .hakorc with all options.

Change Log

v0.1.3 (Latest)

Editor renamed to hake (binary) / hako-edit (repo). Aligns with the v0.1.6 hako-code + hako-models suite.

• CLI rename: hako → hake. Source file hako.c → hake.c; macros HAKO_* → HAKE_*; status bar reads HAKE v0.1.3; help text + --version updated. Splash now shows EDIT under the block-letter logo.
• Subprocess wire updated. Internal symbols claw* → hako* (the wire is to the hako agent, not to the legacy claw name). hakeFindBinary searches for hako on PATH / ~/.local/bin / /usr/local/bin. BUNDLE_HAKO=1 (default) compiles ../hako-code/hako.c alongside hake.
• Mithraeum default theme — void / paper / gold / rust palette matches the site banners + hake / hako-code icons. Boot default; 17 other presets still available via :theme <name>.
• SIGPIPE-safe — hako agent crashing mid-turn no longer kills the editor; hakoSendLine detects EPIPE, hakoShutdown reaps cleanly.
• Config consolidation. Both hake and hako read ~/.hakorc (was ~/.hakocrc on the agent side); editor-only keys and AI keys coexist under sectioned headers.

See CHANGELOG.md for full history.
