whattsreply

wh

Terminal WhatsApp client (ratatui) with per-chat and global AI autoreply via an OpenAI-compatible API.

Build

cargo build --release

Cross-compile: Linux x86_64 static (musl)

Built from Windows with cargo-zigbuild. Zig provides the C cross-compiler and linker for the bundled C code (SQLite, aws-lc-sys, ring).

One-time prerequisites:

rustup target add x86_64-unknown-linux-musl
winget install -e --id zig.zig      # or: pip install ziglang
cargo install --locked cargo-zigbuild

Build:

cargo zigbuild --release --target x86_64-unknown-linux-musl

Output: target/x86_64-unknown-linux-musl/release/wh

Verify on Linux:

file wh   # ELF 64-bit x86-64, statically linked
chmod +x wh && ./wh

Data directory

On Linux, config and databases live in ~/.config/wh/ (config.toml, session.db, history.db); on Windows in %APPDATA%\wh.

Copy session.db from Windows to reuse the linked session instead of scanning the QR again.

Configuration

Settings live in config.toml in the data directory. Start from config.toml.global.template: copy it there and fill openai_api_key and system_prompt. A missing file means defaults; without openai_api_key and system_prompt the app runs as a plain WhatsApp client.

Web control panel

• Enabled by web_port in config.toml (e.g. web_port = 8080); open http://<host>:<port>/.
• Listens on 0.0.0.0 without authentication: use it only on a trusted network (e.g. a VPN).
• The page (HTML/CSS/JS) is embedded in the binary: no extra files to deploy.
• Features: "AI tutte" switch (same as Ctrl+Shift+A), per-chat AI toggle grid (private chats and groups only), "Chiudi bot" button to quit. The page refreshes every 5 seconds; changes show up in the TUI too.
• API (for scripts): GET /api/state (JSON {global_autoreply, chats:[{jid,name,autoreply}], status}); POST /api/global; POST /api/chat with the jid as plain-text body; POST /api/quit. Every POST requires the header X-Wh-Request: 1 (otherwise 403), which blocks cross-site requests from other pages.

Example:

curl -X POST -H "X-Wh-Request: 1" http://host:8080/api/global
