Build

cargo build --release

Usage as library

use npcrs::{Kernel, NPC, Team};

// Boot kernel with a team directory
let kernel = Kernel::boot("./npc_team", "~/npcsh_history.db")?;

// Execute through the agent loop (tools, delegation, etc.)
let output = kernel.exec(0, "what files are in this directory?").await?;

// Delegate to a specific NPC
let output = kernel.delegate(0, "corca", "refactor this function").await?;

Usage as npcsh (shell)

Build and run from npcsh/rust/:

cd npcsh/rust
cargo build --release
./target/release/npcsh

Or symlink as npc for direct .npc/.jinx execution:

ln -sf $(pwd)/target/release/npcsh ~/.local/bin/npc

# Run NPC files directly
npc ./npc_team/sibiji.npc "hello"

# Run jinx files directly
npc ./npc_team/jinxes/lib/sh.jinx bash_command="echo hi"

# Scaffold a new team
npc init

Cross-compile for Android

# Add targets
rustup target add aarch64-linux-android x86_64-linux-android

# Set NDK env
export ANDROID_NDK_HOME=/path/to/ndk
export CC_aarch64_linux_android=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android34-clang
export AR_aarch64_linux_android=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin/llvm-ar

# Build
cargo build --lib --target aarch64-linux-android --release

# Copy to Flutter project
cp target/aarch64-linux-android/release/libnpcrs.so /path/to/flutter/android/app/src/main/jniLibs/arm64-v8a/

FFI

Produces cdylib and staticlib for embedding in Flutter, Android, iOS, desktop apps. See src/ffi/mod.rs for the C-ABI exports and eazy-phone/lib/npc/npcrs_bindings.dart for the Dart bindings.

DB

Uses the same ~/npcsh_history.db and conversation_history table schema as the Python npcsh. Both versions can share the same database.
