RenderGold 
Martini middleware/handler for parsing Gold templates and rendering HTML
About Gold
Gold is a template engine for Go. Please visit its GitHub repository for more details.
Usage
Here is an example of server-side Go code:
package main
import (
"github.com/go-martini/martini"
"github.com/yosssi/rendergold"
)
func main() {
m := martini.Classic()
m.Use(rendergold.Renderer()) // reads "templates" directory by default
m.Get("/", func(r rendergold.Render) {
r.HTML(200, "top", nil) // parses "templates/top.gold"
})
m.Run()
}
Here is an example of templates/top.gold:
doctype html
html
head
title RenderGold
body
h1 Hello RenderGold!
This template will be converted to the following HTML:
<!DOCTYPE html>
<html>
<head>
<title>RenderGold</title>
</head>
<body>
<h1>Hello RenderGold!</h1>
</body>
</html>
Options
rendergold.Renderer comes with a variety of configuration options:
// ...
m.Use(render.Renderer(render.Options{
Directory: "templates", // Specify what path to load the templates from. Default is "templates".
Func: template.FuncMap{AppHelpers}, // Specify helper function map for templates to access.
Charset: "UTF-8", // Sets encoding for html content-types. Default is "UTF-8".
HTMLContentType: "application/xhtml+xml", // Output XHTML content type instead of default "text/html".
Asset: Asset, // Asset loads and returns the asset for the given name.
}))
// ...
Load templates from binary data generated by go-bindata
You can load templates from binary data generated by go-bindata by setting the Asset function (which is generated by go-bindata) to the rendergold.renderer via rendergold.Options.
package main
import (
"net/http"
"github.com/martini-contrib/staticbin"
"github.com/yosssi/rendergold"
)
func main() {
m := staticbin.Classic(Asset)
// Set the `Asset` function generated by go-bindata
// to the `rendergold.renderer` via `rendergold.Options`.
m.Use(rendergold.Renderer(rendergold.Options{Asset: Asset}))
m.Get("/", func(r rendergold.Render) {
r.HTML(
http.StatusOK,
"top",
map[string]interface{}{
"Title": "Gold - Template engine for Go",
},
)
})
m.Run()
}

)
func main() {
m := martini.Classic()
m.Use(rendergold.Renderer()) // reads "templates" directory by default
m.Get("/", func(r rendergold.Render) {
r.HTML(200, "mytemplate", nil)
})
m.Run()
}

Functions ¶
func Renderer ¶
Renderer is a Middleware that maps a render.Render service into the Martini handler chain. An single variadic rendergold.Options struct can be optionally provided to configure HTML rendering. The default directory for templates is "templates" and the default file extension is ".gold".
If MARTINI_ENV is set to "" or "development" then templates will be parsed every request. For more performance, set the MARTINI_ENV environment variable to "production"
Types ¶
type Options ¶
type Options struct {
// Directory to load templates. Default is "templates"
Directory string
// Funcs is a slice of FuncMaps to apply to the template upon compilation. This is useful for helper functions. Defaults to [].
Func template.FuncMap
// Appends the given charset to the Content-Type header. Default is "UTF-8".
Charset string
// Allows changing of output to XHTML instead of HTML. Default is "text/html"
HTMLContentType string
// Asset loads and returns the asset for the given name.
Asset func(string) ([]byte, error)
}
Options is a struct for specifying configuration options for the render.Renderer middleware
type Render ¶
type Render interface {
// HTML renders a html template specified by the name and writes the result and given status to the http.ResponseWriter.
HTML(status int, name string, v interface{}, htmlOpt ...render.HTMLOptions)
// Redirect redirects the request.
Redirect(location string, status ...int)
}
Render is a service that can be injected into a Martini handler. Render provides functions for easily writing HTML templates out to a http Response.
