Install

go get github.com/foolin/gin-template

Usage

package main

import (
	"github.com/gin-gonic/gin"
	"github.com/foolin/gin-template"
	"net/http"
)

func main() {
	router := gin.Default()

	//new template engine
	router.HTMLRender = gintemplate.Default()

	router.GET("/page", func(ctx *gin.Context) {
		ctx.HTML(http.StatusOK, "page.html", gin.H{"title": "Page file title!!"})
	})

	router.Run(":9090")
}

Configure

    TemplateConfig{
		Root:      "views", //template root path
		Extension: ".tpl", //file extension
		Master:    "layouts/master", //master layout file
		Partials:  []string{"partials/head"}, //partial files
		Funcs: template.FuncMap{
			"sub": func(a, b int) int {
				return a - b
			},
			// more funcs
		},
		DisableCache: false, //if disable cache, auto reload template file for debug.
	}

Render

Render with master

The ctx is instance of *gin.Context

//use name without extension `.html`
ctx.HTML(http.StatusOK, "index", gin.H{})
Render only file(not use master layout)
//use full name with extension `.html`
ctx.HTML(http.StatusOK, "page.html", gin.H{})

Include syntax

//template file
{{include "layouts/footer"}}

Examples

Basic example

package main

import (
	"github.com/gin-gonic/gin"
	"github.com/foolin/gin-template"
	"net/http"
)

func main() {
	router := gin.Default()

	//new template engine
	router.HTMLRender = gintemplate.Default()

	router.GET("/", func(ctx *gin.Context) {
		//render with master
		ctx.HTML(http.StatusOK, "index", gin.H{
			"title": "Index title!",
			"add": func(a int, b int) int {
				return a + b
			},
		})
	})


	router.GET("/page", func(ctx *gin.Context) {
		//render only file, must full name with extension
		ctx.HTML(http.StatusOK, "page.html", gin.H{"title": "Page file title!!"})
	})

	router.Run(":9090")
}
