This is a forked version of the original jocker/jade repo that implements a fix (Joker/jade#57) allowing to deal with nested mixin blocks.
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.
example:
//- :go:func Index(pageTitle string, youAreUsingJade bool)
mixin for(golang)
#cmd Precompile jade templates to #{golang} code.

html(lang="en")

Install jade compiler
go install github.com/Joker/jade/cmd/jade@latestor github.com/Joker/jade package
go get -u github.com/Joker/jadejade -writer -pkg=main hello.jadejade command1 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 Jade_hello(word string, wr io.Writer) {
buffer := &WriterAsBuffer{wr}
buffer.WriteString(hello__0)
WriteEscString(word, buffer)
buffer.WriteString(hello__1)

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.

html/templategeneration doesn't support the following features:
=>means it generate the folowing templatefor => "{{/* %s, %s */}}{{ range %s }}" for if => "{{ if gt len %s 0 }}{{/* %s, %s */}}{{ range %s }}" multiline code => "{{/* %s */}}" inheritance block => "{{/* block */}}" case statement => "{{/* switch %s */}}" when => "{{/* case %s: */}}" default => "{{/* default: */}}"You can change this behaviour in
config.gofile.
Partly this problem can be solved by custom functions. ↩
