# SF Native Engine
|
|
|
|
Rust N-API addon providing high-performance native modules for SF.
|
|
|
|
## Architecture
|
|
|
|
```
|
|
JS (packages/native) -> N-API -> Rust crates
|
|
|
|
rust-engine/crates/
|
|
├── engine/ (N-API bindings, cdylib — 20+ modules)
|
|
├── grep/ (ripgrep internals, pure Rust lib)
|
|
└── ast/ (ast-grep structural search)
|
|
```
|
|
|
|
Inspired by [Oh My Pi's pi-natives](https://github.com/can1357/oh-my-pi), adapted for SF's Node.js runtime.
|
|
|
|
## Prerequisites
|
|
|
|
- **Rust** (stable, 1.70+): https://rustup.rs
|
|
- **Node.js** (24.0.0+)
|
|
|
|
## Build
|
|
|
|
```bash
|
|
# Release build (optimized)
|
|
npm run build:native
|
|
|
|
# Debug build (fast compile, no optimizations)
|
|
npm run build:native:dev
|
|
```
|
|
|
|
The build script compiles the Rust code and copies the `.node` shared library to `rust-engine/addon/`.
|
|
|
|
## Test
|
|
|
|
```bash
|
|
# Rust unit tests
|
|
cd native && cargo test
|
|
|
|
# Node.js integration tests
|
|
npm run test:native
|
|
```
|
|
|
|
## Modules
|
|
|
|
### ast
|
|
|
|
Structural code search via ast-grep. Provides pattern-based code matching that understands language syntax, enabling searches like "find all functions that return a Promise" rather than raw regex.
|
|
|
|
### clipboard
|
|
|
|
Native clipboard access for reading and writing system clipboard contents.
|
|
|
|
### diff
|
|
|
|
Fuzzy text matching and unified diff generation. Provides efficient comparison of text content with configurable matching thresholds.
|
|
|
|
### fd
|
|
|
|
Fuzzy file path discovery. Locates files by partial name matching across the project tree.
|
|
|
|
### fs_cache
|
|
|
|
Filesystem caching layer. Caches file metadata and contents to reduce redundant I/O during repeated operations.
|
|
|
|
### git
|
|
|
|
Libgit2-backed git read operations. Provides fast, direct access to repository status, diffs, blame, and log without shelling out to the `git` CLI.
|
|
|
|
### glob / glob_util
|
|
|
|
Gitignore-aware file discovery. Walks directory trees while respecting `.gitignore` rules, returning matching paths for a given glob pattern.
|
|
|
|
### grep
|
|
|
|
Ripgrep-backed regex search using the `grep-regex`, `grep-searcher`, and `grep-matcher` crates.
|
|
|
|
**Functions:**
|
|
|
|
- `search(content, options)` — Search in-memory Buffer/Uint8Array content
|
|
- `grep(options)` — Search files on disk with glob filtering and .gitignore support
|
|
|
|
**TypeScript usage:**
|
|
|
|
```typescript
|
|
import { grep, searchContent } from "@sf/native";
|
|
|
|
// Search files
|
|
const result = grep({
|
|
pattern: "TODO",
|
|
path: "./src",
|
|
glob: "*.ts",
|
|
ignoreCase: true,
|
|
maxCount: 100,
|
|
});
|
|
|
|
// Search content
|
|
const contentResult = searchContent(Buffer.from(fileContent), {
|
|
pattern: "function\\s+\\w+",
|
|
contextBefore: 2,
|
|
contextAfter: 2,
|
|
});
|
|
```
|
|
|
|
### sf_parser
|
|
|
|
SF file parsing and frontmatter extraction. Reads `.sf` files and extracts structured metadata from YAML frontmatter blocks.
|
|
|
|
### highlight
|
|
|
|
Syntect-based syntax highlighting. Tokenizes source code and produces highlighted output for terminal or HTML rendering.
|
|
|
|
### html
|
|
|
|
HTML-to-Markdown conversion. Transforms HTML content into clean Markdown, useful for importing web content into SF notes and documents.
|
|
|
|
### image
|
|
|
|
Image decoding, encoding, and resizing. Supports common formats (PNG, JPEG, WebP) and provides efficient thumbnail generation.
|
|
|
|
### json_parse
|
|
|
|
JSON parsing utilities. Provides streaming and fault-tolerant JSON parsing for large or partially valid payloads.
|
|
|
|
### ps
|
|
|
|
Cross-platform process tree management. Lists, inspects, and terminates process trees by PID, used for managing spawned subprocesses.
|
|
|
|
### stream_process
|
|
|
|
Streaming process I/O. Spawns child processes with non-blocking, streamed access to stdout and stderr for real-time output handling.
|
|
|
|
### task
|
|
|
|
Task-related native operations. Provides low-level primitives for task scheduling and execution within the native layer.
|
|
|
|
### text
|
|
|
|
ANSI-aware text measurement and wrapping. Correctly measures visible width of strings containing ANSI escape codes and wraps text to terminal column widths.
|
|
|
|
### truncate
|
|
|
|
Text truncation utilities. Truncates strings to a target length while preserving ANSI sequences and respecting grapheme boundaries.
|
|
|
|
### ttsr
|
|
|
|
Tool-triggered system rules. Evaluates and applies system-level rules that activate in response to specific tool invocations.
|
|
|
|
### xxhash
|
|
|
|
xxHash hashing. Provides fast, non-cryptographic hashing via the xxHash algorithm for content deduplication and cache keying.
|
|
|
|
## Adding New Modules
|
|
|
|
1. Create a new crate in `rust-engine/crates/` (pure Rust library)
|
|
2. Add N-API bindings in `rust-engine/crates/engine/src/`
|
|
3. Add TypeScript wrapper in `package./rust-engine/src/`
|
|
4. Add the crate to `engine/Cargo.toml` dependencies
