# Exportable C NOSTR Library Design Guide
|
|
||||||
|
|
||||||
This document outlines the design principles and structure for making the C NOSTR library easily exportable and reusable across multiple projects.
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
|
|
||||||
The C NOSTR library is designed as a modular, self-contained implementation that can be easily integrated into other projects while maintaining compatibility with the broader NOSTR ecosystem.
|
|
||||||
|
|
||||||
## Design Principles
|
|
||||||
|
|
||||||
### 1. Modular Architecture
|
|
||||||
- **Core Layer**: Essential NOSTR functionality (`nostr_core.c/h`)
|
|
||||||
- **Crypto Layer**: Self-contained cryptographic primitives (`nostr_crypto.c/h`)
|
|
||||||
- **WebSocket Layer**: Optional networking functionality (`nostr_websocket/`)
|
|
||||||
- **Dependencies**: Minimal external dependencies (only cJSON and mbedTLS)
|
|
||||||
|
|
||||||
### 2. Clean API Surface
|
|
||||||
- Consistent function naming with `nostr_` prefix
|
|
||||||
- Clear return codes using `NOSTR_SUCCESS`/`NOSTR_ERROR_*` constants
|
|
||||||
- Well-documented function signatures
|
|
||||||
- No global state where possible
|
|
||||||
|
|
||||||
### 3. Self-Contained Crypto
|
|
||||||
- Custom implementations of SHA-256, HMAC, secp256k1
|
|
||||||
- BIP39 wordlist embedded in code
|
|
||||||
- No external crypto library dependencies for core functionality
|
|
||||||
- Optional mbedTLS integration for enhanced security
|
|
||||||
|
|
||||||
### 4. Cross-Platform Compatibility
|
|
||||||
- Standard C99 code
|
|
||||||
- Platform-specific code isolated in separate modules
|
|
||||||
- ARM64 and x86_64 tested builds
|
|
||||||
- Static library compilation support
|
|
||||||
|
|
||||||

|
|
||||||
## Integration Methods
|
|
||||||
|
|
||||||
### Method 1: Static Library Linking
|
|
||||||
|
|
||||||
**Best for**: Applications that want a single binary with all NOSTR functionality embedded.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Build the library
|
|
||||||
make lib
|
|
||||||
|
|
||||||
# In your project Makefile:
|
|
||||||
CFLAGS += -I/path/to/c_nostr
|
|
||||||
LDFLAGS += -L/path/to/c_nostr -lnostr_core -lm -static
|
|
||||||
```
|
|
||||||
|
|
||||||
**Usage:**
|
|
||||||
```c
|
|
||||||
#include "nostr_core.h"
|
|
||||||
|
|
||||||
int main() {
|
|
||||||
if (nostr_init() != NOSTR_SUCCESS) {
|
|
||||||
return 1;
|
|
||||||
}
|
|
||||||
|
|
||||||
unsigned char private_key[32], public_key[32];
|
|
||||||
nostr_generate_keypair(private_key, public_key);
|
|
||||||
|
|
||||||
cJSON* event = nostr_create_text_event("Hello NOSTR!", private_key);
|
|
||||||
// ... use event
|
|
||||||
|
|
||||||
nostr_cleanup();
|
|
||||||
return 0;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Method 2: Source Code Integration
|
|
||||||
|
|
||||||
**Best for**: Applications that want to customize the crypto backend or minimize dependencies.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Copy essential files to your project:
|
|
||||||
cp nostr_core.{c,h} your_project/src/
|
|
||||||
cp nostr_crypto.{c,h} your_project/src/
|
|
||||||
cp -r cjson/ your_project/src/
|
|
||||||
```
|
|
||||||
|
|
||||||
**Compile with your project:**
|
|
||||||
```c
|
|
||||||
// In your source
|
|
||||||
#include "nostr_core.h"
|
|
||||||
// Use NOSTR functions directly
|
|
||||||
```
|
|
||||||
|
|
||||||
### Method 3: Git Submodule
|
|
||||||
|
|
||||||
**Best for**: Projects that want to track upstream changes and contribute back.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# In your project root:
|
|
||||||
git submodule add https://github.com/yourorg/c_nostr.git deps/c_nostr
|
|
||||||
git submodule update --init --recursive
|
|
||||||
|
|
||||||
# In your Makefile:
|
|
||||||
CFLAGS += -Ideps/c_nostr
|
|
||||||
LDFLAGS += -Ldeps/c_nostr -lnostr_core
|
|
||||||
```
|
|
||||||
|
|
||||||
### Method 4: Shared Library
|
|
||||||
|
|
||||||
**Best for**: System-wide installation or multiple applications sharing the same NOSTR implementation.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Install system-wide
|
|
||||||
sudo make install
|
|
||||||
|
|
||||||
# In your project:
|
|
||||||
CFLAGS += $(pkg-config --cflags nostr_core)
|
|
||||||
LDFLAGS += $(pkg-config --libs nostr_core)
|
|
||||||
```
|
|
||||||
|
|
||||||
## API Design for Exportability
|
|
||||||
|
|
||||||
### Consistent Error Handling
|
|
||||||
```c
|
|
||||||
typedef enum {
|
|
||||||
NOSTR_SUCCESS = 0,
|
|
||||||
NOSTR_ERROR_INVALID_INPUT = -1,
|
|
||||||
NOSTR_ERROR_CRYPTO_FAILED = -2,
|
|
||||||
NOSTR_ERROR_MEMORY_ALLOCATION = -3,
|
|
||||||
NOSTR_ERROR_JSON_PARSE = -4,
|
|
||||||
NOSTR_ERROR_NETWORK = -5
|
|
||||||
} nostr_error_t;
|
|
||||||
|
|
||||||
const char* nostr_strerror(int error_code);
|
|
||||||
```
|
|
||||||
|
|
||||||
### Clean Resource Management
|
|
||||||
```c
|
|
||||||
// Always provide cleanup functions
|
|
||||||
int nostr_init(void);
|
|
||||||
void nostr_cleanup(void);
|
|
||||||
|
|
||||||
// JSON objects returned should be freed by caller
|
|
||||||
cJSON* nostr_create_text_event(const char* content, const unsigned char* private_key);
|
|
||||||
// Caller must call cJSON_Delete(event) when done
|
|
||||||
```
|
|
||||||
|
|
||||||
### Optional Features
|
|
||||||
```c
|
|
||||||
// Compile-time feature toggles
|
|
||||||
#ifndef NOSTR_DISABLE_WEBSOCKETS
|
|
||||||
int nostr_connect_relay(const char* url);
|
|
||||||
#endif
|
|
||||||
|
|
||||||
#ifndef NOSTR_DISABLE_IDENTITY_PERSISTENCE
|
|
||||||
int nostr_save_identity(const unsigned char* private_key, const char* password, int account);
|
|
||||||
#endif
|
|
||||||
```
|
|
||||||
|
|
||||||
## Configuration System
|
|
||||||
|
|
||||||
### Build-Time Configuration
|
|
||||||
```c
|
|
||||||
// nostr_config.h (generated during build)
|
|
||||||
#define NOSTR_VERSION "1.0.0"
|
|
||||||
#define NOSTR_HAS_MBEDTLS 1
|
|
||||||
#define NOSTR_HAS_WEBSOCKETS 1
|
|
||||||
#define NOSTR_STATIC_BUILD 1
|
|
||||||
```
|
|
||||||
|
|
||||||
### Runtime Configuration
|
|
||||||
```c
|
|
||||||
typedef struct {
|
|
||||||
int log_level;
|
|
||||||
char* identity_file_path;
|
|
||||||
int default_account;
|
|
||||||
int enable_networking;
|
|
||||||
} nostr_config_t;
|
|
||||||
|
|
||||||
int nostr_set_config(const nostr_config_t* config);
|
|
||||||
const nostr_config_t* nostr_get_config(void);
|
|
||||||
```
|
|
||||||
|
|
||||||
## Testing and Validation
|
|
||||||
|
|
||||||
### Ecosystem Compatibility Testing
|
|
||||||
The library includes comprehensive test suites that validate compatibility with reference implementations like `nak`:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Run all tests
|
|
||||||
cd tests && make test
|
|
||||||
|
|
||||||
# Test specific functionality
|
|
||||||
make test-crypto # Cryptographic primitives
|
|
||||||
make test-core # High-level NOSTR functions
|
|
||||||
```
|
|
||||||
|
|
||||||
### Test Vectors
|
|
||||||
Real-world test vectors are generated using `nak` to ensure ecosystem compatibility:
|
|
||||||
- Key generation and derivation (BIP39/BIP32)
|
|
||||||
- Event creation and signing
|
|
||||||
- Bech32 encoding/decoding
|
|
||||||
- Message serialization
|
|
||||||
|
|
||||||
## Documentation for Exporters
|
|
||||||
|
|
||||||
### Essential Files Checklist
|
|
||||||
For projects integrating this library, you need:
|
|
||||||
|
|
||||||
**Core Files (Required):**
|
|
||||||
- `nostr_core.h` - Main API
|
|
||||||
- `nostr_core.c` - Implementation
|
|
||||||
- `nostr_crypto.h` - Crypto API
|
|
||||||
- `nostr_crypto.c` - Self-contained crypto
|
|
||||||
- `cjson/` directory - JSON parsing
|
|
||||||
|
|
||||||
**Optional Files:**
|
|
||||||
- `nostr_websocket/` - WebSocket relay support
|
|
||||||
- `mbedtls/` - Enhanced crypto backend
|
|
||||||
- `examples/` - Usage examples
|
|
||||||
- `tests/` - Validation tests
|
|
||||||
|
|
||||||
### Minimal Integration Example
|
|
||||||
```c
|
|
||||||
// minimal_nostr.c - Smallest possible integration
|
|
||||||
#include "nostr_core.h"
|
|
||||||
|
|
||||||
int main() {
|
|
||||||
// Initialize library
|
|
||||||
nostr_init();
|
|
||||||
|
|
||||||
// Generate keypair
|
|
||||||
unsigned char priv[32], pub[32];
|
|
||||||
nostr_generate_keypair(priv, pub);
|
|
||||||
|
|
||||||
// Create and sign event
|
|
||||||
cJSON* event = nostr_create_text_event("Hello from my app!", priv);
|
|
||||||
char* json_string = cJSON_Print(event);
|
|
||||||
printf("Event: %s\n", json_string);
|
|
||||||
|
|
||||||
// Cleanup
|
|
||||||
free(json_string);
|
|
||||||
cJSON_Delete(event);
|
|
||||||
nostr_cleanup();
|
|
||||||
return 0;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
**Compile:**
|
|
||||||
```bash
|
|
||||||
gcc -I. minimal_nostr.c nostr_core.c nostr_crypto.c cjson/cJSON.c -lm -o minimal_nostr
|
|
||||||
```
|
|
||||||
|
|
||||||
## Future Considerations
|
|
||||||
|
|
||||||
### Language Bindings
|
|
||||||
The C library is designed to be easily wrapped:
|
|
||||||
- **Python**: Use ctypes or cffi
|
|
||||||
- **JavaScript**: Use Node.js FFI or WASM compilation
|
|
||||||
- **Go**: Use cgo
|
|
||||||
- **Rust**: Use bindgen for FFI bindings
|
|
||||||
|
|
||||||
### WebAssembly Support
|
|
||||||
The library can be compiled to WebAssembly for browser usage:
|
|
||||||
```bash
|
|
||||||
emcc -O3 -s WASM=1 -s EXPORTED_FUNCTIONS='["_nostr_init", "_nostr_generate_keypair"]' \
|
|
||||||
nostr_core.c nostr_crypto.c cjson/cJSON.c -o nostr.wasm
|
|
||||||
```
|
|
||||||
|
|
||||||
### Package Manager Support
|
|
||||||
Future versions may include:
|
|
||||||
- pkgconfig files for system installation
|
|
||||||
- CMake integration for easier builds
|
|
||||||
- vcpkg/Conan package definitions
|
|
||||||
|
|
||||||
## Contributing Back
|
|
||||||
|
|
||||||
Projects using this library are encouraged to:
|
|
||||||
1. Report compatibility issues
|
|
||||||
2. Submit test vectors from their use cases
|
|
||||||
3. Contribute performance improvements
|
|
||||||
4. Add support for additional NIPs
|
|
||||||
|
|
||||||
## Version Compatibility
|
|
||||||
|
|
||||||
The library follows semantic versioning:
|
|
||||||
- **Major**: Breaking API changes
|
|
||||||
- **Minor**: New features, backward compatible
|
|
||||||
- **Patch**: Bug fixes
|
|
||||||
|
|
||||||
API stability guarantees:
|
|
||||||
- All functions prefixed with `nostr_` are part of the stable API
|
|
||||||
- Internal functions (static or prefixed with `_`) may change
|
|
||||||
- Configuration structures may be extended but not modified
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
This design ensures the C NOSTR library can be easily adopted by other projects while maintaining high compatibility with the NOSTR ecosystem standards.

# c-nostr Export and Implementation Guide
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
|
|
||||||
This guide provides essential information for developers using the `c-nostr` library, particularly regarding the capabilities and limitations of its self-contained modules, such as the HTTP client.
|
|
||||||
|
|
||||||
## HTTP Client (`http_client.c`)
|
|
||||||
|
|
||||||
The `http_client` module is a lightweight, self-contained HTTP/HTTPS client designed for simple and direct web requests. It is ideal for tasks like fetching NIP-11 information from Nostr relays or interacting with standard, permissive web APIs.
|
|
||||||
|
|
||||||
### Key Features
|
|
||||||
|
|
||||||
* **Self-Contained**: It is built with `mbedTLS` and has no external dependencies beyond standard C libraries, making it highly portable.
|
|
||||||
* **Simplicity**: It provides a straightforward `http_get()` function for making web requests.
|
|
||||||
* **TLS Support**: It supports HTTPS and basic TLS 1.3/1.2 features, including SNI (Server Name Indication) and ALPN (Application-Layer Protocol Negotiation).
|
|
||||||
|
|
||||||
### Limitations
|
|
||||||
|
|
||||||
The `http_client` is intentionally simple and is **not a full-featured web browser**. Due to its minimalist design, it will likely be blocked by websites that employ advanced anti-bot protection systems.
|
|
||||||
|
|
||||||
* **Incompatibility with Advanced Bot Protection**: Sites like Google, Cloudflare, and others use sophisticated fingerprinting techniques to distinguish between real browsers and automated clients. They analyze the exact combination of TLS cipher suites, TLS extensions, and HTTP headers. Our client's fingerprint does not match a standard browser, so these sites will preemptively drop the connection, typically resulting in a `HTTP_ERROR_NETWORK` error.
|
|
||||||
|
|
||||||
* **Intended Use Case**: This client is best suited for interacting with known, friendly APIs and Nostr relays. It is **not** designed for general web scraping or for accessing services that are heavily guarded against automated traffic.
|
|
||||||
|
|
||||||
### Best Practices
|
|
||||||
|
|
||||||
* **Use for APIs and Relays**: Rely on this client for fetching data from well-defined, public endpoints that do not have aggressive bot-detection measures in place.
|
|
||||||
* **Avoid Protected Sites**: Do not attempt to use this client to access services like Google Search, as such attempts will fail. For those use cases, a full-featured library like `libcurl` or a dedicated web-scraping framework is required.
|
|
||||||
* **Check the Test Suite**: The `tests/http_client_test.c` file contains test cases that demonstrate both the successful use cases (e.g., `httpbin.org`) and the expected failures (e.g., `google.com`), providing a clear reference for the client's capabilities.

# Generic Automatic Version Increment System for Any Repository
|
|
||||||
|
|
||||||
Here's a generalized implementation guide for adding automatic versioning to any project:
|
|
||||||
|
|
||||||
## Core Concept
|
|
||||||
**Automatic patch version increment with each build** - Every build automatically increments the patch version: v0.1.0 → v0.1.1 → v0.1.2, etc.
|
|
||||||
|
|
||||||
## Implementation Steps
|
|
||||||
|
|
||||||
### 1. Add Version Increment Function to Build Script
|
|
||||||
Add this function to your build script (bash example):
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Function to automatically increment version
|
|
||||||
increment_version() {
|
|
||||||
echo "[INFO] Incrementing version..."
|
|
||||||
|
|
||||||
# Check if we're in a git repository
|
|
||||||
if ! git rev-parse --git-dir > /dev/null 2>&1; then
|
|
||||||
echo "[WARNING] Not in a git repository - skipping version increment"
|
|
||||||
return 0
|
|
||||||
fi
|
|
||||||
|
|
||||||
# Get the highest version tag (not chronologically latest)
|
|
||||||
LATEST_TAG=$(git tag -l 'v*.*.*' | sort -V | tail -n 1 || echo "v0.1.0")
|
|
||||||
if [[ -z "$LATEST_TAG" ]]; then
|
|
||||||
LATEST_TAG="v0.1.0"
|
|
||||||
fi
|
|
||||||
|
|
||||||
# Extract version components (remove 'v' prefix)
|
|
||||||
VERSION=${LATEST_TAG#v}
|
|
||||||
|
|
||||||
# Parse major.minor.patch using regex
|
|
||||||
if [[ $VERSION =~ ^([0-9]+)\.([0-9]+)\.([0-9]+)$ ]]; then
|
|
||||||
MAJOR=${BASH_REMATCH[1]}
|
|
||||||
MINOR=${BASH_REMATCH[2]}
|
|
||||||
PATCH=${BASH_REMATCH[3]}
|
|
||||||
else
|
|
||||||
echo "[ERROR] Invalid version format in tag: $LATEST_TAG"
|
|
||||||
echo "[ERROR] Expected format: v0.1.0"
|
|
||||||
return 1
|
|
||||||
fi
|
|
||||||
|
|
||||||
# Increment patch version
|
|
||||||
NEW_PATCH=$((PATCH + 1))
|
|
||||||
NEW_VERSION="v${MAJOR}.${MINOR}.${NEW_PATCH}"
|
|
||||||
|
|
||||||
echo "[INFO] Current version: $LATEST_TAG"
|
|
||||||
echo "[INFO] New version: $NEW_VERSION"
|
|
||||||
|
|
||||||
# Create new git tag
|
|
||||||
if git tag "$NEW_VERSION" 2>/dev/null; then
|
|
||||||
echo "[SUCCESS] Created new version tag: $NEW_VERSION"
|
|
||||||
else
|
|
||||||
echo "[WARNING] Tag $NEW_VERSION already exists - using existing version"
|
|
||||||
NEW_VERSION=$LATEST_TAG
|
|
||||||
fi
|
|
||||||
|
|
||||||
# Update VERSION file for compatibility
|
|
||||||
echo "${NEW_VERSION#v}" > VERSION
|
|
||||||
echo "[SUCCESS] Updated VERSION file to ${NEW_VERSION#v}"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### 2. Generate Version Header Files (For C/C++ Projects)
|
|
||||||
Add this to the increment_version function:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Generate version.h header file (adjust path as needed)
|
|
||||||
cat > src/version.h << EOF
|
|
||||||
/*
|
|
||||||
* Auto-Generated Version Header
|
|
||||||
* DO NOT EDIT THIS FILE MANUALLY - Generated by build script
|
|
||||||
*/
|
|
||||||
|
|
||||||
#ifndef VERSION_H
|
|
||||||
#define VERSION_H
|
|
||||||
|
|
||||||
#define VERSION_MAJOR ${MAJOR}
|
|
||||||
#define VERSION_MINOR ${MINOR}
|
|
||||||
#define VERSION_PATCH ${NEW_PATCH}
|
|
||||||
#define VERSION_STRING "${MAJOR}.${MINOR}.${NEW_PATCH}"
|
|
||||||
#define VERSION_TAG "${NEW_VERSION}"
|
|
||||||
|

|
|
||||||
### 3. Generate Version File for Other Languages
|
|
||||||
|
|
||||||
**Python (`src/__version__.py`):**
|
|
||||||
```bash
|
|
||||||
cat > src/__version__.py << EOF
|
|
||||||
"""Auto-generated version file"""
|
|
||||||
__version__ = "${MAJOR}.${MINOR}.${NEW_PATCH}"
|
|
||||||
__version_tag__ = "${NEW_VERSION}"
|
|
||||||
__build_date__ = "$(date +%Y-%m-%d)"
|
|
||||||
__build_time__ = "$(date +%H:%M:%S)"
|
|
||||||
__git_hash__ = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
|
|
||||||
__git_branch__ = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
|
|
||||||
EOF
|
|
||||||
```
|
|
||||||
|
|
||||||
**JavaScript/Node.js (update `package.json`):**
|
|
||||||
```bash
|
|
||||||
# Update package.json version field
|
|
||||||
if [ -f package.json ]; then
|
|
||||||
sed -i "s/\"version\": \".*\"/\"version\": \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" package.json
|
|
||||||
fi
|
|
||||||
```
|
|
||||||
|
|
||||||
**Rust (update `Cargo.toml`):**
|
|
||||||
```bash
|
|
||||||
if [ -f Cargo.toml ]; then
|
|
||||||
sed -i "s/^version = \".*\"/version = \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" Cargo.toml
|
|
||||||
fi
|
|
||||||
```
|
|
||||||
|
|
||||||
**Go (generate `version.go`):**
|
|
||||||
```bash
|
|
||||||
cat > version.go << EOF
|
|
||||||
// Auto-generated version file
|
|
||||||
package main
|
|
||||||
|
|
||||||
const (
|
|
||||||
VersionMajor = ${MAJOR}
|
|
||||||
VersionMinor = ${MINOR}
|
|
||||||
VersionPatch = ${NEW_PATCH}
|
|
||||||
VersionString = "${MAJOR}.${MINOR}.${NEW_PATCH}"
|
|
||||||
VersionTag = "${NEW_VERSION}"
|
|
||||||
BuildDate = "$(date +%Y-%m-%d)"
|
|
||||||
BuildTime = "$(date +%H:%M:%S)"
|
|
||||||
GitHash = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
|
|
||||||
GitBranch = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
|
|
||||||
)
|
|
||||||
EOF
|
|
||||||
```
|
|
||||||
|
|
||||||
**Java (generate `Version.java`):**
|
|
||||||
```bash
|
|
||||||
cat > src/main/java/Version.java << EOF
|
|
||||||
// Auto-generated version class
|
|
||||||
public class Version {
|
|
||||||
public static final int VERSION_MAJOR = ${MAJOR};
|
|
||||||
public static final int VERSION_MINOR = ${MINOR};
|
|
||||||
public static final int VERSION_PATCH = ${NEW_PATCH};
|
|
||||||
public static final String VERSION_STRING = "${MAJOR}.${MINOR}.${NEW_PATCH}";
|
|
||||||
public static final String VERSION_TAG = "${NEW_VERSION}";
|
|
||||||
public static final String BUILD_DATE = "$(date +%Y-%m-%d)";
|
|
||||||
public static final String BUILD_TIME = "$(date +%H:%M:%S)";
|
|
||||||
public static final String GIT_HASH = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')";
|
|
||||||
public static final String GIT_BRANCH = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')";
|
|
||||||
}
|
|
||||||
EOF
|
|
||||||
```
|
|
||||||
|
|
||||||
### 4. Integrate into Build Targets
|
|
||||||
Call `increment_version` before your main build commands:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
build_library() {
|
|
||||||
increment_version
|
|
||||||
echo "[INFO] Building library..."
|
|
||||||
# Your actual build commands here
|
|
||||||
make clean && make
|
|
||||||
}
|
|
||||||
|
|
||||||
build_release() {
|
|
||||||
increment_version
|
|
||||||
echo "[INFO] Building release..."
|
|
||||||
# Your release build commands
|
|
||||||
}
|
|
||||||
|
|
||||||
build_package() {
|
|
||||||
increment_version
|
|
||||||
echo "[INFO] Building package..."
|
|
||||||
# Your packaging commands
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### 5. Update .gitignore
|
|
||||||
Add generated version files to `.gitignore`:
|
|
||||||
|
|
||||||
```gitignore
|
|
||||||
# Auto-generated version files
|
|
||||||
src/version.h
|
|
||||||
src/version.c
|
|
||||||
src/__version__.py
|
|
||||||
version.go
|
|
||||||
src/main/java/Version.java
|
|
||||||
VERSION
|
|
||||||
```
|
|
||||||
|
|
||||||
### 6. Update Build System Files
|
|
||||||
|
|
||||||
**For Makefile projects:**
|
|
||||||
```makefile
|
|
||||||
# Add version.c to your source files
|
|
||||||
SOURCES = main.c utils.c version.c
|
|
||||||
```
|
|
||||||
|
|
||||||
**For CMake projects:**
|
|
||||||
```cmake
|
|
||||||
# Add version files to your target
|
|
||||||
target_sources(your_target PRIVATE src/version.c)
|
|
||||||
```
|
|
||||||
|
|
||||||
**For Node.js projects:**
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"scripts": {
|
|
||||||
"build": "node build.js && increment_version",
|
|
||||||
"version": "node -e \"console.log(require('./package.json').version)\""
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### 7. Create Initial Version Tag
|
|
||||||
```bash
|
|
||||||
# Start with initial version
|
|
||||||
git tag v0.1.0
|
|
||||||
```
|
|
||||||
|
|
||||||
## Usage Pattern
|
|
||||||
```bash
|
|
||||||
./build.sh # v0.1.0 → v0.1.1
|
|
||||||
./build.sh release # v0.1.1 → v0.1.2
|
|
||||||
./build.sh package # v0.1.2 → v0.1.3
|
|
||||||
```
|
|
||||||
|
|
||||||
## Manual Version Control
|
|
||||||
|
|
||||||
### Major/Minor Version Bumps
|
|
||||||
```bash
|
|
||||||
# For feature releases (minor bump)
|
|
||||||
git tag v0.2.0 # Next build: v0.2.1
|
|
||||||
|
|
||||||
# For breaking changes (major bump)
|
|
||||||
git tag v1.0.0 # Next build: v1.0.1
|
|
||||||
```
|
|
||||||
|
|
||||||
### Version Reset
|
|
||||||
```bash
|
|
||||||
# Delete incorrect tags (if needed)
|
|
||||||
git tag -d v0.2.1
|
|
||||||
git push origin --delete v0.2.1 # If pushed to remote
|
|
||||||
|
|
||||||
# Create correct base version
|
|
||||||
git tag v0.2.0
|
|
||||||
|
|
||||||
# Next build will create v0.2.1
|
|
||||||
```
|
|
||||||
|
|
||||||
## Example Build Script Template
|
|
||||||
```bash
|
|
||||||
#!/bin/bash
|
|
||||||
set -e
|
|
||||||
|
|
||||||
# Colors for output
|
|
||||||
RED='\033[0;31m'
|
|
||||||
GREEN='\033[0;32m'
|
|
||||||
YELLOW='\033[1;33m'
|
|
||||||
BLUE='\033[0;34m'
|
|
||||||
NC='\033[0m'
|
|
||||||
|
|
||||||
print_status() { echo -e "${BLUE}[INFO]${NC} $1"; }
|
|
||||||
print_success() { echo -e "${GREEN}[SUCCESS]${NC} $1"; }
|
|
||||||
print_warning() { echo -e "${YELLOW}[WARNING]${NC} $1"; }
|
|
||||||
print_error() { echo -e "${RED}[ERROR]${NC} $1"; }
|
|
||||||
|
|
||||||
# Insert increment_version function here
|
|
||||||
|
|
||||||
case "${1:-build}" in
|
|
||||||
build)
|
|
||||||
increment_version
|
|
||||||
print_status "Building project..."
|
|
||||||
# Your build commands
|
|
||||||
;;
|
|
||||||
clean)
|
|
||||||
print_status "Cleaning build artifacts..."
|
|
||||||
# Your clean commands
|
|
||||||
;;
|
|
||||||
test)
|
|
||||||
print_status "Running tests..."
|
|
||||||
# Your test commands (no version increment)
|
|
||||||
;;
|
|
||||||
release)
|
|
||||||
increment_version
|
|
||||||
print_status "Building release..."
|
|
||||||
# Your release commands
|
|
||||||
;;
|
|
||||||
*)
|
|
||||||
echo "Usage: $0 {build|clean|test|release}"
|
|
||||||
exit 1
|
|
||||||
;;
|
|
||||||
esac
|
|
||||||
```
|
|
||||||
|
|
||||||
## Benefits
|
|
||||||
1. **Zero maintenance** - No manual version editing
|
|
||||||
2. **Build traceability** - Every build has unique version + metadata
|
|
||||||
3. **Git integration** - Automatic version tags
|
|
||||||
4. **Language agnostic** - Adapt generation for any language
|
|
||||||
5. **CI/CD friendly** - Works in automated environments
|
|
||||||
6. **Rollback friendly** - Easy to revert to previous versions
|
|
||||||
|
|
||||||
## Troubleshooting
|
|
||||||
|
|
||||||
### Version Not Incrementing
|
|
||||||
- Ensure you're in a git repository
|
|
||||||
- Check that git tags exist: `git tag --list`
|
|
||||||
- Verify tag format matches `v*.*.*` pattern
|
|
||||||
|
|
||||||
### Tag Already Exists
|
|
||||||
If a tag already exists, the build continues with existing version:
|
|
||||||
```
|
|
||||||
[WARNING] Tag v0.2.1 already exists - using existing version
|
|
||||||
```
|
|
||||||
|
|
||||||
### Missing Git Information
|
|
||||||
If git is unavailable, version files show "unknown" for git hash and branch.

# NOSTR Core Library - Usage Guide
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
|
|
||||||
The NOSTR Core Library (`libnostr_core`) is a self-contained, exportable C library for NOSTR protocol implementation. It requires **no external cryptographic dependencies** (no OpenSSL, no libwally) and can be easily integrated into other projects.
|
|
||||||
|
|
||||||
## Key Features
|
|
||||||
|
|
||||||
- **Self-Contained Crypto**: All cryptographic operations implemented from scratch
|
|
||||||
- **Zero External Dependencies**: Only requires standard C library, cJSON, and libwebsockets
|
|
||||||
- **Cross-Platform**: Builds on Linux, macOS, Windows (with appropriate toolchain)
|
|
||||||
- **NIP-06 Compliant**: Proper BIP39/BIP32 implementation for key derivation
|
|
||||||
- **Thread-Safe**: Core cryptographic functions are stateless and thread-safe
|
|
||||||
- **Easy Integration**: Simple C API with clear error handling
|
|
||||||
|
|
||||||
## File Structure for Export
|
|
||||||
|
|
||||||

|
|
||||||
```
|
|
||||||
|
|
||||||
## Integration Methods
|
|
||||||
|
|
||||||
### Method 1: Static Library Integration
|
|
||||||
|
|
||||||
1. **Copy Required Files**:
|
|
||||||
```bash
|
|
||||||
cp nostr_core.h nostr_core.c nostr_crypto.h nostr_crypto.c /path/to/your/project/
|
|
||||||
cp -r cjson/ /path/to/your/project/
|
|
||||||
```
|
|
||||||
|
|
||||||
2. **Build Static Library**:
|
|
||||||
```bash
|
|
||||||
gcc -c -fPIC nostr_core.c nostr_crypto.c cjson/cJSON.c
|
|
||||||
ar rcs libnostr_core.a nostr_core.o nostr_crypto.o cJSON.o
|
|
||||||
```
|
|
||||||
|
|
||||||
3. **Link in Your Project**:
|
|
||||||
```bash
|
|
||||||
gcc your_project.c -L. -lnostr_core -lm -o your_project
|
|
||||||
```
|
|
||||||
|
|
||||||
### Method 2: Direct Source Integration
|
|
||||||
|
|
||||||
Simply include the source files directly in your project:
|
|
||||||
|
|
||||||
```c
|
|
||||||
// In your project
|
|
||||||
#include "nostr_core.h"
|
|
||||||
|
|
||||||
// Compile with:
|
|
||||||
// gcc your_project.c nostr_core.c nostr_crypto.c cjson/cJSON.c -lm
|
|
||||||
```
|
|
||||||
|
|
||||||
### Method 3: Shared Library Integration
|
|
||||||
|
|
||||||
1. **Build Shared Library**:
|
|
||||||
```bash
|
|
||||||
make libnostr_core.so
|
|
||||||
```
|
|
||||||
|
|
||||||
2. **Install System-Wide** (optional):
|
|
||||||
```bash
|
|
||||||
sudo cp libnostr_core.so /usr/local/lib/
|
|
||||||
sudo cp nostr_core.h /usr/local/include/
|
|
||||||
sudo ldconfig
|
|
||||||
```
|
|
||||||
|
|
||||||
3. **Use in Projects**:
|
|
||||||
```bash
|
|
||||||
gcc your_project.c -lnostr_core -lm
|
|
||||||
```
|
|
||||||
|
|
||||||
## Building the Library
|
|
||||||
|
|
||||||
### Using the Provided Build Script
|
|
||||||
|
|
||||||
The library includes an automated build script that handles all dependencies and creates a self-contained static library.
|
|
||||||
|
|
||||||
**IMPORTANT**: The build script must be run from within the `nostr_core_lib` directory:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Correct usage:
|
|
||||||
cd nostr_core_lib
|
|
||||||
./build.sh
|
|
||||||
|
|
||||||
# If you need to use it from your project directory:
|
|
||||||
cd nostr_core_lib
|
|
||||||
./build.sh
|
|
||||||
cd ..
|
|
||||||
gcc your_app.c nostr_core_lib/libnostr_core_x64.a -lz -ldl -lpthread -lm -o your_app
|
|
||||||
```
|
|
||||||
|
|
||||||
**Common Error**: Running `./nostr_core_lib/build.sh` from outside the library directory will fail with:
|
|
||||||
```
|
|
||||||
[ERROR] Build script must be run from the nostr_core_lib directory
|
|
||||||
```
|
|
||||||
|
|
||||||
### Build Script Options
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Auto-detect NIPs from your source code
|
|
||||||
./build.sh
|
|
||||||
|
|
||||||
# Force specific NIPs
|
|
||||||
./build.sh --nips=1,6,19
|
|
||||||
|
|
||||||
# Build all available NIPs
|
|
||||||
./build.sh --nips=all
|
|
||||||
|
|
||||||
# Build for specific architecture
|
|
||||||
./build.sh arm64
|
|
||||||
|
|
||||||
# Build with tests
|
|
||||||
./build.sh --tests
|
|
||||||
|
|
||||||
# Get help
|
|
||||||
./build.sh --help
|
|
||||||
```
|
|
||||||
|
|
||||||
The build script automatically:
|
|
||||||
- Scans your `.c` files for `#include "nip*.h"` statements
|
|
||||||
- Compiles only the needed NIPs
|
|
||||||
- Creates a self-contained static library (`libnostr_core_x64.a`)
|
|
||||||
- Includes all dependencies (OpenSSL, curl, secp256k1, cJSON)
|
|
||||||
|
|
||||||
## Basic Usage Example
|
|
||||||
|
|
||||||
```c
|
|
||||||
#include "nostr_core.h"
|
|
||||||
#include <stdio.h>
|
|
||||||
#include <stdlib.h>
|
|
||||||
|
|
||||||
int main() {
|
|
||||||
// Initialize the library
|
|
||||||
if (nostr_init() != NOSTR_SUCCESS) {
|
|
||||||
fprintf(stderr, "Failed to initialize NOSTR library\n");
|
|
||||||
return 1;
|
|
||||||
}
|
|
||||||
|
|
||||||
// Generate a keypair
|
|
||||||
unsigned char private_key[32];
|
|
||||||
unsigned char public_key[32];
|
|
||||||
|
|
||||||
if (nostr_generate_keypair(private_key, public_key) != NOSTR_SUCCESS) {
|
|
||||||
fprintf(stderr, "Failed to generate keypair\n");
|
|
||||||

|
|
||||||
## Dependency Management
|
|
||||||
|
|
||||||
### Required Dependencies
|
|
||||||
- **Standard C Library**: malloc, string functions, file I/O
|
|
||||||
- **Math Library**: `-lm` (for cryptographic calculations)
|
|
||||||
- **cJSON**: JSON parsing (included, or use system version)
|
|
||||||
|
|
||||||
### Optional Dependencies
|
|
||||||
- **libwebsockets**: Only needed for relay communication functions
|
|
||||||
- **System cJSON**: Can replace bundled version
|
|
||||||
|
|
||||||
### Minimal Integration (Crypto Only)
|
|
||||||
If you only need key generation and signing:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Build with minimal dependencies
|
|
||||||
gcc -DNOSTR_CRYPTO_ONLY your_project.c nostr_crypto.c -lm
|
|
||||||
```
|
|
||||||
|
|
||||||
## Cross-Platform Considerations
|
|
||||||
|
|
||||||
### Linux
|
|
||||||
- Works out of the box with GCC
|
|
||||||
- Install build-essential: `sudo apt install build-essential`
|
|
||||||
|
|
||||||
### macOS
|
|
||||||
- Works with Xcode command line tools
|
|
||||||
- May need: `xcode-select --install`
|
|
||||||
|
|
||||||
### Windows
|
|
||||||
- Use MinGW-w64 or MSYS2
|
|
||||||
- Or integrate with Visual Studio project
|
|
||||||
|
|
||||||
### Embedded Systems
|
|
||||||
- Library is designed to work on resource-constrained systems
|
|
||||||
- No heap allocations in core crypto functions
|
|
||||||
- Stack usage is predictable and bounded
|
|
||||||
|
|
||||||
## API Reference
|
|
||||||
|
|
||||||
### Initialization
|
|
||||||
```c
|
|
||||||
int nostr_init(void); // Initialize library
|
|
||||||
void nostr_cleanup(void); // Cleanup resources
|
|
||||||
const char* nostr_strerror(int error); // Get error string
|
|
||||||
```
|
|
||||||
|
|
||||||
### Key Generation
|
|
||||||
```c
|
|
||||||
int nostr_generate_keypair(unsigned char* private_key, unsigned char* public_key);
|
|
||||||
int nostr_generate_mnemonic_and_keys(char* mnemonic, size_t mnemonic_size,
|
|
||||||
int account, unsigned char* private_key,
|
|
||||||
unsigned char* public_key);
|
|
||||||
int nostr_derive_keys_from_mnemonic(const char* mnemonic, int account,
|
|
||||||
unsigned char* private_key, unsigned char* public_key);
|
|
||||||
```
|
|
||||||
|
|
||||||
### Event Creation
|
|
||||||
```c
|
|
||||||
cJSON* nostr_create_text_event(const char* content, const unsigned char* private_key);
|
|
||||||
cJSON* nostr_create_profile_event(const char* name, const char* about,
|
|
||||||
const unsigned char* private_key);
|
|
||||||
int nostr_sign_event(cJSON* event, const unsigned char* private_key);
|
|
||||||
```
|
|
||||||
|
|
||||||
### Utilities
|
|
||||||
```c
|
|
||||||
void nostr_bytes_to_hex(const unsigned char* bytes, size_t len, char* hex);
|
|
||||||
int nostr_hex_to_bytes(const char* hex, unsigned char* bytes, size_t len);
|
|
||||||
int nostr_key_to_bech32(const unsigned char* key, const char* hrp, char* output);
|
|
||||||
nostr_input_type_t nostr_detect_input_type(const char* input);
|
|
||||||
```
|
|
||||||
|
|
||||||
## Error Handling
|
|
||||||
|
|
||||||
All functions return standardized error codes:
|
|
||||||
|
|
||||||
- `NOSTR_SUCCESS` (0): Operation successful
|
|
||||||
- `NOSTR_ERROR_INVALID_INPUT` (-1): Invalid parameters
|
|
||||||
- `NOSTR_ERROR_CRYPTO_FAILED` (-2): Cryptographic operation failed
|
|
||||||
- `NOSTR_ERROR_MEMORY_FAILED` (-3): Memory allocation failed
|
|
||||||
- `NOSTR_ERROR_IO_FAILED` (-4): File I/O operation failed
|
|
||||||
- `NOSTR_ERROR_NETWORK_FAILED` (-5): Network operation failed
|
|
||||||
|
|
||||||
## Security Considerations
|
|
||||||
|
|
||||||
1. **Private Key Handling**: Always clear private keys from memory when done
|
|
||||||
2. **Random Number Generation**: Uses `/dev/urandom` on Unix systems
|
|
||||||
3. **Memory Safety**: All buffers are bounds-checked
|
|
||||||
4. **Constant-Time Operations**: Critical crypto operations are timing-attack resistant
|
|
||||||
|
|
||||||
