# Examples and Usage
|
|
|
|
This document provides working examples of Core v2 functionality in both code and CLI forms. All examples are runnable and tested.
|
|
|
|
## CLI Examples
|
|
|
|
For interactive usage, see the [CLI Documentation](./cli.md). Quick example:
|
|
|
|
```bash
|
|
# Build and start the daemon
|
|
cargo build --release
|
|
./target/release/spacedrive start
|
|
|
|
# Create a library and add locations
|
|
./target/release/spacedrive library create "Personal"
|
|
./target/release/spacedrive location add ~/Documents --name "Documents"
|
|
./target/release/spacedrive job monitor
|
|
```
|
|
|
|
## Running Code Examples
|
|
|
|
```bash
|
|
# Library management and database operations
|
|
cargo run --example library_demo
|
|
|
|
# Job system demonstration
|
|
cargo run --example job_demo
|
|
|
|
# File type detection system
|
|
cargo run --example file_type_demo
|
|
|
|
# Database operations and schema
|
|
cargo run --example database_test
|
|
|
|
# Content indexing workflows
|
|
cargo run --example content_indexing
|
|
```
|
|
|
|
## Basic Core Usage
|
|
|
|
### Initializing Core
|
|
|
|
```rust
|
|
use sd_core_new::Core;
|
|
|
|
#[tokio::main]
|
|
async fn main() -> Result<(), Box<dyn std::error::Error>> {
|
|
// Initialize with default data directory
|
|
let core = Core::new().await?;
|
|
|
|
// Or specify custom directory
|
|
let custom_core = Core::new_with_config(
|
|
PathBuf::from("/custom/spacedrive/data")
|
|
).await?;
|
|
|
|
println!("Device ID: {}", core.device.device_id()?);
|
|
println!("Device Name: {}", core.device.device_name()?);
|
|
|
|
// Core automatically handles cleanup on drop
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
### Core Shutdown
|
|
|
|
```rust
|
|
// Graceful shutdown
|
|
async fn shutdown_example(core: Core) -> Result<(), Box<dyn std::error::Error>> {
|
|
// Manually trigger shutdown for cleanup
|
|
core.shutdown().await?;
|
|
println!("Core shutdown complete");
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
## Library Management
|
|
|
|
### Creating Libraries
|
|
|
|
```rust
|
|
use sd_core_new::Core;
|
|
use std::path::PathBuf;
|
|
|
|
async fn create_library_example() -> Result<(), Box<dyn std::error::Error>> {
|
|
let core = Core::new().await?;
|
|
|
|
// Create library with auto-generated path
|
|
let library = core.libraries
|
|
.create_library("My Documents", None)
|
|
.await?;
|
|
|
|
println!("Library created: {}", library.name().await);
|
|
println!("Library path: {}", library.path().display());
|
|
println!("Library ID: {}", library.id());
|
|
|
|
// Create library at specific location
|
|
let specific_library = core.libraries
|
|
.create_library("Projects", Some(PathBuf::from("/home/user/projects")))
|
|
.await?;
|
|
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
### Opening and Closing Libraries
|
|
|
|
```rust
|
|
async fn library_lifecycle_example() -> Result<(), Box<dyn std::error::Error>> {
|
|
let core = Core::new().await?;
|
|
|
|
// Create a library
|
|
let library = core.libraries
|
|
.create_library("Test Library", None)
|
|
.await?;
|
|
|
|
let library_path = library.path().to_path_buf();
|
|
let library_id = library.id();
|
|
|
|
// Close the library
|
|
core.libraries.close_library(library_id).await?;
|
|
|
|
// Drop the library reference to release locks
|
|
drop(library);
|
|
|
|
// Reopen the library
|
|
let reopened = core.libraries
|
|
.open_library(&library_path)
|
|
.await?;
|
|
|
|
assert_eq!(reopened.id(), library_id);
|
|
println!("Library reopened successfully");
|
|
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
### Library Discovery
|
|
|
|
```rust
|
|
async fn library_discovery_example() -> Result<(), Box<dyn std::error::Error>> {
|
|
let core = Core::new().await?;
|
|
|
|
// Scan for existing libraries
|
|
let discovered = core.libraries.scan_for_libraries().await?;
|
|
println!("Found {} libraries", discovered.len());
|
|
|
|
for discovered_lib in discovered {
|
|
println!(" - {} at {}",
|
|
discovered_lib.name,
|
|
discovered_lib.path.display()
|
|
);
|
|
}
|
|
|
|
// Auto-load all libraries
|
|
let loaded_count = core.libraries.load_all().await?;
|
|
println!("Loaded {} libraries", loaded_count);
|
|
|
|
// List currently open libraries
|
|
let open_libraries = core.libraries.list().await;
|
|
for library in open_libraries {
|
|
println!("Open: {} ({})", library.name().await, library.id());
|
|
}
|
|
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
## Database Operations
|
|
|
|

|
|
async fn create_entry_example(library: &Library) -> Result<(), Box<dyn std::error::Error>> {
|
|
let db = library.db();
|
|
|
|
// Create metadata first (every entry needs metadata)
|
|
let metadata = entities::user_metadata::ActiveModel {

|
|
};
|
|
let metadata_record = metadata.insert(db.conn()).await?;
|
|
|
|
// No need for path prefixes - we use materialized paths directly
|
|
|
|
// Create the entry
|
|
let entry = entities::entry::ActiveModel {
|
|
id: NotSet,
|
|
uuid: Set(Uuid::new_v4()),

## Job System Usage
|
|
|
|
### Creating and Running Jobs
|
|
|
|
```rust
|
|
use sd_core_new::{
|
|
infrastructure::jobs::manager::JobManager,
|
|
operations::{
|
|
file_ops::copy_job::FileCopyJob,

|
async fn progress_reporting_example() {
|
|
// Simple percentage progress
|
|
let progress = Progress::percentage(0.75); // 75% complete

|
|
};
|
|
|
|
let structured_progress = Progress::structured(custom_progress);

## File Type System
|
|
|
|
```rust
|
|

|
|
}
|
|
}
|
|
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
## Event System
|
|
|
|
```rust
|
|
use sd_core_new::infrastructure::events::{Event, EventBus};
|
|
|
|
async fn event_system_example() -> Result<(), Box<dyn std::error::Error>> {

|
|
|
|
### Library Testing

|
|
|
```rust
|
|
#[tokio::test]

|
|
use tempfile::TempDir;
|
|
|
|
// Create temporary directory for test

let temp_dir = TempDir::new().unwrap();
|
|
let core = Core::new_with_config(temp_dir.path().to_path_buf()).await.unwrap();
|
|
|
|
// Create library
|
|
let library = core.libraries
|
|
.create_library("Test Library", None)
|
|

// Test configuration updates
|
|
library.update_config(|config| {
