package go/doc
ToText prepares comment text for presentation in textual output. It wraps paragraphs of text to width or fewer Unicode code points and then prefixes each line with the indent. In preformatted sections (such as program text), it prefixes each non-blank line with preIndent.
Golang go/doc.ToText() function usage example
package main
import (
"fmt"
"go/doc"
"bytes"
)
func main() {
var buf bytes.Buffer
comment := "// this line is a comment line"
doc.ToText(&buf, comment, "**", "####", 30)
fmt.Println(buf.String())
}
Output :
**// this line is a comment line
