# atom
|
|
|
|
An extensible Atom feed generator library that aims to be very close to RFC4287.
|
|
It diligently checks for compliance with the standard and provides functions for
|
|
easy creation and extension of elements.
|
|
|
|
## Installation
|
|
|
|
To install the latest version of the module, use the following command:
|
|
|
|
```sh
|
|
go get git.streifling.com/jason/atom@latest
|
|
```
|
|
|
|
## Usage
|
|
|
|
This library provides convenient functions to safely create and extend elements
|
|
and attributes of Atom feeds. It also provides checks for all constructs'
|
|
adherence to RFC4287.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"log"
|
|
|
|
"git.streifling.com/jason/atom"
|
|
)
|
|
|
|
func main() {
|
|
feed := atom.NewFeed("Example Feed")
|
|
if err := feed.Check(); err != nil {
|
|
log.Fatalln(err)
|
|
}
|
|
|
|
author := atom.NewPerson("John Doe")
|
|
author.Email = "john.doe@example.com"
|
|
if err := author.Check(); err != nil {
|
|
log.Fatalln(err)
|
|
}
|
|
feed.AddAuthor(author)
|
|
|
|
entry := atom.NewEntry("First Entry")
|
|
entry.Content = atom.NewContent(atom.InlineText, "text", "This is the content of the first entry.")
|
|
if err := entry.Check(); err != nil {
|
|
log.Fatalln(err)
|
|
}
|
|
feed.AddEntry(entry)
|
|
|
|
feedString, err := feed.ToXML("utf-8")
|
|
if err != nil {
|
|
log.Fatalln(err)
|
|
}
|
|
fmt.Println(feedString)
|
|
}
|
|
```
|
|
|
|
It is also possible to use this library in a way similar to what other libraries
|
|
provide.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"log"
|
|
"time"
|
|
|
|
"git.streifling.com/jason/atom"
|
|
)
|
|
|
|
func main() {
|
|
now := time.Now()
|
|
|
|
feed := &atom.Feed{
|
|
Title: &atom.PlainText{
|
|
Type: "text",
|
|
Text: "Example Feed",
|
|
},
|
|
ID: &atom.ID{URI: "urn:uuid:60a76c80-d399-11d9-b93C-0003939e0af6"},
|
|
Updated: &atom.Date{DateTime: atom.DateTime(now)},
|
|
Authors: []*atom.Person{
|
|
{
|
|
Name: "John Doe",
|
|
Email: "john.doe@example.com",
|
|
},
|
|
},
|
|
Entries: []*atom.Entry{
|
|
{
|
|
Title: &atom.PlainText{
|
|
Type: "text",
|
|
Text: "First Entry",
|
|
},
|
|
ID: &atom.ID{URI: "urn:uuid:1225c695-cfb8-4ebb-aaaa-80da344efa6a"},
|
|
Updated: &atom.Date{DateTime: atom.DateTime(now)},
|
|
Content: &atom.InlineTextContent{
|
|
Type: "text",
|
|
Text: "This is the content of the first entry.",
|
|
},
|
|
},
|
|
},
|
|
}
|
|
|
|
feedString, err := feed.ToXML("utf-8")
|
|
if err != nil {
|
|
log.Fatalln(err)
|
|
}
|
|
fmt.Println(feedString)
|
|
}
|
|
```
|
|
|
|
The output of both ways of using it is an RFC4287 compliant Atom feed.
|
|
|
|
```xml
|
|
<?xml version="1.0" encoding="utf-8"?>
|
|
<feed xmlns="http://www.w3.org/2005/Atom">
|
|
<author>
|
|

|
|
<email>john.doe@example.com</email>
|
|
