Go templates: http://golang.org <http://golang.org/> Fast and simple with gRPC
and other good stuff like kelsey’s confd (a daemon that watches for changes and
update templates)
% go doc text/template
package template // import "text/template"
Package template implements data-driven templates for generating textual
output.
To generate HTML output, see package html/template, which has the same
interface as this package but automatically secures HTML output against
certain attacks.
Templates are executed by applying them to a data structure. Annotations in
the template refer to elements of the data structure (typically a field of a
struct or a key in a map) to control execution and derive values to be
displayed. Execution of the template walks the structure and sets the
cursor, represented by a period '.' and called "dot", to the value at the
current location in the structure as execution proceeds.
The input text for a template is UTF-8-encoded text in any format.
"Actions"--data evaluations or control structures--are delimited by "{{" and
"}}"; all text outside actions is copied to the output unchanged. Except for
raw strings, actions may not span newlines, although comments can.
Once parsed, a template may be executed safely in parallel.
Here is a trivial example that prints "17 items are made of wool".
type Inventory struct {
Material string
Count uint
}
sweaters := Inventory{"wool", 17}
tmpl, err := template.New("test").Parse("{{.Count}} items are made of
{{.Material}}")
if err != nil { panic(err) }
err = tmpl.Execute(os.Stdout, sweaters)
if err != nil { panic(err) }
