| 8 | +# Feed.TXT - A Free Feeds Format in Plain Text w/ Structured Meta Data |
| 9 | + |
| 10 | + |
| 11 | +What's Feed.TXT? Let's start with an example from the JSON Feed spec: |
| 12 | + |
| 13 | +```json |
| 14 | +{ |
| 15 | + "version": "https://jsonfeed.org/version/1", |
| 16 | + "title": "My Example Feed", |
| 17 | + "home_page_url": "https://example.org/", |
| 18 | + "feed_url": "https://example.org/feed.json", |
| 19 | + "items": [ |
| 20 | + { |
| 21 | + "id": "2", |
| 22 | + "content_text": "This is a second item.", |
| 23 | + "url": "https://example.org/second-item" |
| 24 | + }, |
| 25 | + { |
| 26 | + "id": "1", |
| 27 | + "content_html": "<p>Hello, world!</p>", |
| 28 | + "url": "https://example.org/initial-post" |
| 29 | + } |
| 30 | + ] |
| 31 | +} |
| 32 | +``` |
| 33 | + |
| 34 | +Simple, isn't it? Let's try just text: |
| 35 | + |
| 36 | +``` |
| 37 | +|>>> |
| 38 | + title: My Example Feed |
| 39 | + home_page_url: https://example.org/ |
| 40 | + feed_url: https://example.org/feed.txt |
| 41 | + </> |
| 42 | + id: 2 |
| 43 | + url: https://example.org/second-item |
| 44 | + --- |
| 45 | + This is a second item. |
| 46 | + </> |
| 47 | + id: 1 |
| 48 | + url: https://example.org/initial-post |
| 49 | + --- |
| 50 | + Hello, world! |
| 51 | +<<<| |
| 52 | +``` |
| 53 | + |
| 54 | +Are you serious, really? Let's try another example from the JSON Feed spec: |
| 55 | + |
| 56 | +```json |
| 57 | +{ |
| 58 | + "version": "https://jsonfeed.org/version/1", |
| 59 | + "user_comment": "This is a podcast feed. You can add this feed to your podcast client using the following URL: http://therecord.co/feed.json", |

| 62 | + "feed_url": "http://therecord.co/feed.json", |
| 63 | + "items": [ |

| 68 | + "content_text": "Chris has worked at Adobe and as a founder of Rogue Sheep, which won an Apple Design Award for Postage.

| 78 | + } |
| 79 | + ] |
| 80 | + } |
| 81 | + ] |
| 82 | +} |
| 83 | +``` |
| 84 | + |
| 85 | +Yes, the world's 1st podcasting feed in plain text ;-) Let's try: |
| 86 | + |
| 87 | +``` |
| 88 | +|>>> |

| 114 | +``` |
| 115 | + |
| 116 | + |
| 117 | +## Spec(ification) - How does it work? |
| 118 | + |
| 119 | +A Feed.txt starts with a meta data block for the feed in YAML format |
| 120 | +followed by a list of items. Items start with a meta data block followed by the text |
| 121 | +using the markdown formatting conventions for structured text (headings, lists, tables, etc.) and |
| 122 | +hyperlinks. That's it. |
| 123 | + |
| 124 | + |
| 125 | +### Dividers - Begin / Next / End |
| 126 | + |
| 127 | +Use `|>>>` to begin a Feed.txt feed. Note you use three or more `>>>` open brackets e.g. |
| 128 | +`|>>>>>>>>>>>>` also works. |
| 129 | + |
| 130 | +Use `<<<|` to end a Feed.txt feed. Again note you can use three or more `<<<` closing brackets e.g. |
| 131 | +`<<<<<<<|` also works. |
| 132 | + |
| 133 | +Use `</>` to break up items. That's it. |
| 134 | + |
| 135 | + |
| 136 | + |
| 137 | + |
| 138 | +## Use JSON / JSON5 / HJSON / SON for Strucutured Meta Data - |{ }| |
| 139 | + |
| 140 | +As an alternative you can use human JSON for meta data blocks. Let's try: |
| 141 | + |
| 142 | +``` |
| 143 | +|{ |
| 144 | + title: "My Example Feed" |
| 145 | + home_page_url: "https://example.org/" |
| 146 | + feed_url: "https://example.org/feed.txt" |
| 147 | + }/{ |
| 148 | + id: "2" |
| 149 | + url: "https://example.org/second-item" |
| 150 | + } |
| 151 | + This is a second item. |
| 152 | + }/{ |
| 153 | + id: "1" |
| 154 | + url: "https://example.org/initial-post" |
| 155 | + } |
| 156 | + Hello, world! |
| 157 | +}| |
| 158 | +``` |
| 159 | + |
| 160 | +Are you joking? Don't, like the more human JSON style. Let's retry in "classic" JSON: |
| 161 | + |
| 162 | +``` |
| 163 | +|{ |
| 164 | + "title": "My Example Feed", |
| 165 | + "home_page_url": "https://example.org/", |
| 166 | + "feed_url": "https://example.org/feed.txt" |
| 167 | + }/{ |
| 168 | + "id": "2", |
| 169 | + "url": "https://example.org/second-item" |
| 170 | + } |
| 171 | + This is a second item. |
| 172 | + }/{ |
| 173 | + "id": "1", |
| 174 | + "url": "https://example.org/initial-post" |
| 175 | + } |
| 176 | + Hello, world! |
| 177 | +}| |
| 178 | +``` |
| 179 | + |
| 180 | +### Dividers - Begin / Next / End (JSON Edition) |
| 181 | + |
| 182 | +Change `|>>>` to `|{` to begin a Feed.txt feed. Note you use one or more `{` open curly brackets e.g. `|{%raw%}{{{{{%endraw%}` also works. |
| 183 | + |
| 184 | +Change `<<<|` to `}|` to end a Feed.txt feed. Again note you can use one or more `}` closing brackets e.g. `{%raw%}}}}}{%endraw%}|` also works. |
| 185 | + |
| 186 | +Change `</>` to `}/{` to break up items. That's it. |
| 187 | + |
| 188 | + |
| 189 | +Sorry, there's no XML alternative ;-) |
