Overview
This is the Twig compatibility subpackage for Stick.
Current status
Package
bitbucket.org/ticketshopdev/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.
Package
bitbucket.org/ticketshopdev/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.
Installation
The twig package is intended to be used as a library. The recommended
way to install the library is using go get.
go get -u bitbucket.org/ticketshopdev/stick/twig
Usage
Execute a simple Twig template.
package main
import (
"log"
"os"
"bitbucket.org/ticketshopdev/stick"
"bitbucket.org/ticketshopdev/stick/twig"
)
func main() {
env := twig.New(nil)
if err := env.Execute("Hello, {{ name }}!", os.Stdout, map[string]stick.Value{"name": "Tyler"}); err != nil {
log.Fatal(err)
}
}

Overview ¶
Package twig provides Twig 1.x compatible template parsing and executing.
Note: This package is still in development.
Twig is a powerful templating language that promotes separation of logic from the view. This package attempts to replicate the functionality of the Twig engine using the Go programming language.
Twig provides an extensive list of built-in functions, filters, tests, and even auto-escaping. This package provides this functionality out of the box, aiming to fully support the Twig spec.
A simple example might look like:
env := twig.New(nil); // A nil loader means stick will execute
// the string passed into env.Execute.
// Templates receive a map of string to any value.
p := map[string]stick.Value{"name": "World"}
// Substitute os.Stdout with any io.Writer.
env.Execute("Hello, {{ name }}!", os.Stdout, p)
Check the main package https://godoc.org/bitbucket.org/ticketshopdev/stick for more information on general functionality and usage.

Types ¶
type AutoEscapeExtension ¶
AutoEscapeExtension provides Twig equivalent escaping for Stick templates.
Example ¶
This example shows how the AutoEscapeVisitor can be used to automatically sanitize input. It does this by wrapping printed expressions with a filter application, which resolves to stick.EscapeFilter.
package main
import (
"os"
"bitbucket.org/ticketshopdev/stick"
"bitbucket.org/ticketshopdev/stick/twig"
)
func main() {
env := twig.New(nil)
env.Execute("<html>{{ '<script>bad stuff</script>' }}", os.Stdout, map[string]stick.Value{})
}
Output: <html><script>bad stuff</script>
Example (AlreadySafe) ¶
This example displays the EscapeFilter in action.
Note the "already_safe" value wrapped in a NewSafeValue; it is not escaped.
package main
import (
"os"
"bitbucket.org/ticketshopdev/stick"
"bitbucket.org/ticketshopdev/stick/twig"
)
func main() {
env := twig.New(nil)
env.Execute("<html>{{ dangerous|escape }} {{ already_safe|escape }}", os.Stdout, map[string]stick.Value{
"already_safe": stick.NewSafeValue("<script>good script</script>", "html"),
"dangerous": "<script>bad script</script>",
})
}
Output: <html><script>bad script</script> <script>good script</script>
func NewAutoEscapeExtension ¶
func NewAutoEscapeExtension() *AutoEscapeExtension
NewAutoEscapeExtension returns an AutoEscapeExtension with Twig equivalent Escapers, by default.
