Overview

staticweaver is a robust Rust library that provides a flexible and powerful templating engine. Designed for static site generation and more, it offers advanced caching, remote template support, and customizable rendering for optimized performance.

Features

Flexible Template Rendering: Ideal for static sites, web apps, and other use cases.
Dynamic Content: Easily interpolate variables in templates with a powerful context system.
File and String Templates: Render templates from both files and strings.
Advanced Caching: Improve performance by caching templates for repeated use.
Custom Rendering: Modify and extend the rendering process to fit your needs.
Remote Template Support: Fetch and render templates from URLs.
Comprehensive Error Handling: Gracefully manage template rendering errors.

Installation

Add staticweaver to your Cargo.toml:

[dependencies]
staticweaver = "0.0.1"

Usage

Here's a basic example of how to use staticweaver:

use std::fs;
use staticweaver::engine::Engine;
use staticweaver::EngineError;
use staticweaver::error::TemplateError;
use staticweaver::context::Context;
use std::time::Duration;
use std::path::Path;

fn main() -> Result<(), TemplateError> {
    // Create the 'examples' directory and 'template.html' for the test
    fs::create_dir_all("examples")?;
    fs::write("examples/template.html", r#"
    <!DOCTYPE html>
    <html>
    <head><title>{{title}}</title></head>
    <body><h1>{{title}}</h1><p>{{content}}</p></body>
    </html>"#)?;

    // Create a new engine with a template path and cache duration
    let mut engine = Engine::new("examples", Duration::from_secs(60));

    // Create a context with some variables
    let mut context = Context::new();
    context.set("title".to_string(), "Welcome to StaticWeaver".to_string());
    context.set("content".to_string(), "This is a simple example.".to_string());

    // Render the 'template.html', mapping EngineError to TemplateError
    let rendered = engine
        .render_page(&context, "template")
        .map_err(|e| TemplateError::EngineError(Box::new(EngineError::Render(format!("Rendering failed: {:?}", e)))))?;

    // Output the rendered content to 'rendered.html'
    fs::write("examples/rendered.html", &rendered)?;

    println!("Rendered content written to 'examples/rendered.html'.");

    // Clean up: remove files and directory
    remove_dir_contents("examples")?;

    println!("Template and rendered files cleaned up.");

    Ok(())
}

// Helper function to remove all files inside a directory
fn remove_dir_contents(dir: &str) -> std::io::Result<()> {
    let path = Path::new(dir);
    if path.is_dir() {
        for entry in fs::read_dir(path)? {
            let entry = entry?;
            let entry_path = entry.path();
            if entry_path.is_file() {
                fs::remove_file(entry_path)?;
            } else if entry_path.is_dir() {
                fs::remove_dir_all(entry_path)?; // If there are subdirectories, remove them recursively
            }
        }
        fs::remove_dir(path)?; // Finally, remove the directory itself
    }
    Ok(())
}

This example demonstrates rendering a template named "page", replacing {{title}} and {{content}} with values from the context.
