Usage

To illustrate how to use Goview, we can think of templates like baking ingredients; you need the right mixture and ratios to create the final product, which in this case is your web page. Let’s break down the different key areas:

Overview

Consider your project structure as a recipe book where each recipe contains specific ingredients (HTML templates) and instructions (logic). Here’s a simple structure you would have:

go
-- app
    -- views
        -- index.html
        -- page.html
    -- layouts
        -- footer.html
        -- master.html

Config

You can configure Goview like preparing your kitchen. Here’s how to set up your instance:

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,
    Delims:       DelimsLeft: "{", Right: "}",
})

Include Syntax

To include parts of templates like a chef incorporates different flavors, use the following syntax:

{{ template "layouts/footer" . }}

Render Name

Rendering is akin to putting your dish in the oven to bake. Here’s how you can render templates:

goview.Render(writer, http.StatusOK, "index", goview.M)

Custom Template Functions

Just like adding unique spices can elevate a dish, custom template functions can enhance your templates. You can set global and temporary functions as described in the usage section.

Examples

Troubleshooting

If you encounter issues while working with Goview, consider the following troubleshooting tips:

• Check file paths in your configuration. Incorrect paths often lead to template rendering errors.
• Ensure your templates have the correct file extensions and match the configuration settings.
• Review the browser console for errors related to missing resources.
• If dynamic reload isn’t functioning, verify that caching is disabled in your configuration.
