Usage

Overview

Project structure:

|-- app/views/
    |--- index.html          
    |--- page.html
    |-- layouts/
        |--- footer.html
        |--- master.html

Use default instance:

    //write http.ResponseWriter
    //"index" -> index.html
    goview.Render(writer, http.StatusOK, "index", goview.M{})

Use new instance with config:

    gv := goview.New(goview.Config{
        Root:      "views",
        Extension: ".tpl",
        Master:    "layouts/master",
        Partials:  []string{"partials/ad"},
        Funcs: template.FuncMap{
            "sub": func(a, b int) int {
                return a - b
            },
            "copy": func() string {
                return time.Now().Format("2006")
            },
        },
        DisableCache: true,
    })
    
    //Set new instance
    goview.Use(gv)
    
    //write http.ResponseWriter
    goview.Render(writer, http.StatusOK, "index", goview.M{})

Use multiple instance with config:

    //============== Frontend ============== //
    gvFrontend := goview.New(goview.Config{
        Root:      "views/frontend",
        Extension: ".tpl",
        Master:    "layouts/master",
        Partials:  []string{"partials/ad"},
        Funcs: template.FuncMap{
            "sub": func(a, b int) int {
                return a - b
            },
            "copy": func() string {
                return time.Now().Format("2006")
            },
        },
        DisableCache: true,
    })
    
    //write http.ResponseWriter
    gvFrontend.Render(writer, http.StatusOK, "index", goview.M{})
    
    //============== Backend ============== //
    gvBackend := goview.New(goview.Config{
        Root:      "views/backend",
        Extension: ".tpl",
        Master:    "layouts/master",
        Partials:  []string{"partials/ad"},
        Funcs: template.FuncMap{
            "sub": func(a, b int) int {
                return a - b
            },
            "copy": func() string {
                return time.Now().Format("2006")
            },
        },
        DisableCache: true,
    })
    
    //write http.ResponseWriter
    gvBackend.Render(writer, http.StatusOK, "index", goview.M{})

Config

goview.Config{
    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.
}

Include syntax

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

Render name:

Render name use index without .html extension, that will render with master layout.

"index" - Render with master layout.
"index.html" - Not render with master layout.

Notice: `.html` is default template extension, you can change with config

Render with master

//use name without extension `.html`
goview.Render(w, http.StatusOK, "index", goview.M{})

The w is instance of http.ResponseWriter

Render only file(not use master layout)

//use full name with extension `.html`
goview.Render(w, http.StatusOK, "page.html", goview.M{})

Examples

See _examples/ for a variety of examples.
