How to print a GherkinDocument to text with pretty format

[Milk-Tang]

Since I have a GherkinDocument, I wonder how to write it into a file with a pretty format?

Do you mean:

• With syntax coloring ?
• With uniform formatting, like indented with 2 spaces (or: 4 spaces) ?

REGARDING: Syntax coloring / highlighting

• Use gherkin as language/syntax-marker, like:

# — FILE: features/example.feature
Feature: Example 1
  Scenario: S1
    Given a step passes
    When another step passes

Thank you for your reply, but it seems that your intention is to use the formatting of the editor when writing a '.feature' file?
But my question is:

gherkinDocument, err := gherkin.ParseGherkinDocument(reader)
There I got a instance of GherkinDocument by method gherkin.ParseGherkinDocument,
and if I create a GherkinDocument instance by myself but not ParseGherkinDocument,
how can I write it to a ".feature" file in my code?
And here the struct of GherkinDocument :

type GherkinDocument struct {
	Uri      string     `json:"uri,omitempty"`
	Feature  *Feature   `json:"feature,omitempty"`
	Comments []*Comment `json:"comments"`
}
