Extemplate GoDoc Build Status Go Report Card Coverage

Extemplate is a small wrapper package around html/template to allow for easy file-based template inheritance.

File: templates/parent.tmpl

<html>
<head>
	<title>{{ block "title" }}Default title{{ end }}</title>
</head>
<body>
	{{ block "content" }}Default content{{ end }} 
</body>
</html>

File: templates/child.tmpl

{{ extends "parent.tmpl" }}
{{ define "title" }}Child title{{ end }}
{{ define "content" }}Hello world!{{ end }}

File: main.go

xt := extemplate.New()
xt.ParseDir("templates/", []string{".tmpl"})
_ = xt.ExecuteTemplate(os.Stdout, "child.tmpl", "no data needed") 
// Output: <html>.... Hello world! ....</html>

Extemplate recursively walks all files in the given directory and will parse the files matching the given extensions as a template. Templates are named by path and filename, relative to the root directory.

For example, calling ParseDir("templates/", []string{".tmpl"}) on the following directory structure:

templates/
  |__ admin/
  |      |__ index.tmpl
  |      |__ edit.tmpl
  |__ index.tmpl

Will result in the following templates:

admin/index.tmpl
admin/edit.tmpl
index.tmpl

Check out the tests and examples directory for more examples.
