Stick

A Go language port of the Twig templating engine.

Overview

This project is split across two parts.

Package github.com/tyler-sommer/stick is a Twig template parser and executor. It provides the core functionality and offers many of the same extension points as Twig like functions, filters, node visitors, etc.

Package github.com/tyler-sommer/stick/twig contains extensions to provide the most Twig-like experience for template writers. It aims to feature the same functions, filters, etc. to be closely Twig-compatible.

Current status

Stable, mostly feature complete

Stick itself is mostly feature-complete, with the exception of whitespace control, and better error handling in places.

Stick is made up of three main parts: a lexer, a parser, and a template executor. Stick's lexer and parser are complete. Template execution is under development, but essentially complete.

See the to do list for additional information.

Alternatives

These alternatives are worth checking out if you're considering using Stick.

• text/template and html/template from the Go standard library.
• pongo2 is a full-featured Go language port of Django's templating language.

Installation

Stick is intended to be used as a library. The recommended way to install the library is using go get.

go get -u github.com/tyler-sommer/stick

Usage

Execute a simple Stick template.

package main

import (
	"log"
	"os"
    
	"github.com/tyler-sommer/stick"
)

func main() {
	env := stick.New(nil)
	if err := env.Execute("Hello, {{ name }}!", os.Stdout, map[string]stick.Value{"name": "Tyler"}); err != nil {
		log.Fatal(err)
	}
}

To do

• Autoescaping (see: Twig compatibility)
• Whitespace control
• Improve error reporting

Further

• Improve test coverage (especially error cases)
• Custom operators and tags
• Sandbox
• Generate native Go code from a given parser tree
