Template Engine for Go

This is a legacy template engine system, made to be compatible with an older version initially written in PHP.

Features

• Template syntax with interpolation and control structures
• Support for custom filters and functions
• Parallel template execution
• Structured error handling with location information
• Context-aware template execution

Usage

See the [SYNTAX.md](SYNTAX.md) file for template syntax documentation.

package main

import (
	"context"
	"fmt"
	
	"github.com/KarpelesLab/tpl"
)

func main() {
	// Create a new template engine
	engine := tpl.New()
	
	// Add a template
	engine.Raw.TemplateData["main"] = "Hello {{_name}}!"

	// Set up a context with variables
	ctx := context.Background()
	ctx = tpl.ValuesCtx(ctx, map[string]any{
		"_name": "World",
	})
	
	// Compile templates
	if err := engine.Compile(ctx); err != nil {
		panic(err)
	}
	
	// Execute template
	result, err := engine.ParseAndReturn(ctx, "main")
	if err != nil {
		panic(err)
	}
	
	fmt.Println(result) // Output: Hello World!
}
