Jade.go - template engine for Go (golang)

Package jade (github.com/Joker/jade) is a simple and fast template engine implementing Jade/Pug template.
Jade precompiles templates to Go code or generates html/template.
Now Jade-lang is renamed to Pug template engine.

Here are additional examples and test cases.

Example usage

jade command

jade -pkg=main -writer hello.jade

jade command precompiles hello.jade to hello.jade.go

hello.jade

:go:func(arg) word string
doctype 5
html
    body
        p Hello #{word}!

hello.jade.go

// Code generated by "jade.go"; DO NOT EDIT.
package main

import "io"

const (
    hello__0 = `<!DOCTYPE html><html><body><p>Hello `
    hello__1 = `!</p></body></html>`
)
func tpl_hello(word string, wr io.Writer) {
    buffer := &WriterAsBuffer{wr}
    buffer.WriteString(hello__0)
    WriteEscString(word, buffer)
    buffer.WriteString(hello__1)
}

main.go

package main
//go:generate jade -pkg=main -writer hello.jade

import "net/http"

func main() {
    http.HandleFunc("/", func(wr http.ResponseWriter, req *http.Request) {
        tpl_hello("jade", wr)
    })
    http.ListenAndServe(":8080", nil)
}

output at localhost:8080

<!DOCTYPE html><html><body><p>Hello jade!</p></body></html>

github.com/Joker/jade packege

generate html/template at runtime (This case is slightly slower and doesn't support all features of Jade.go)

package main

import (
    "fmt"
    "html/template"
    "net/http"

    "github.com/Joker/hpp" // Prettify HTML
    "github.com/Joker/jade"
)

func handler(w http.ResponseWriter, r *http.Request) {
    jadeTpl, _ := jade.Parse("jade", []byte("doctype 5\n html: body: p Hello #{.Word} !"))
    goTpl, _ := template.New("html").Parse(jadeTpl)

    fmt.Printf("output:%s\n\n", hpp.PrPrint(jadeTpl))
    goTpl.Execute(w, struct{ Word string }{"jade"})
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

console output

<!DOCTYPE html>
<html>
    <body>
        <p>Hello {{.Word}} !</p>
    </body>
</html>

output at localhost:8080

<!DOCTYPE html><html><body><p>Hello jade !</p></body></html>

Installation

$ go get github.com/Joker/jade/cmd/jade

Custom filter :go

This filter is used as helper for command line tool
(to set imports, function name and parameters).
Filter may be placed at any nesting level.
When Jade used as library :go filter is not needed.

Nested filter :func

:go:func
    CustomNameForTemplateFunc(any []int, input string, args map[string]int)

:go:func(name)
    OnlyCustomNameForTemplateFunc

:go:func(args)
    (only string, input float32, args uint)

Nested filter :import

:go:import
    "github.com/Joker/jade"
    github.com/Joker/hpp
