Output format can be used in any rss-bridge:

|
||||
* `format=json` : jSon
|
||||
* `format=html` : html page
|
||||
* `format=plaintext` : raw text (php object, as returned by print_r)
|
||||
|
||||
If format is not specified, ATOM format will be used.
|
||||
|
||||
Examples

||||
===

Technical notes
|
||||
===
|
||||
* There is a cache so that source services won't ban you even if you hammer the rss-bridge with requests. Each bridge has a different duration for the cache. The `cache` subdirectory will be automatically created. You can purge it whenever you want.
|
||||
* To implement a new rss-bridge, import `rss-bridge-lib.php` and subclass `RssBridgeAbstractClass`. Look at existing bridges for examples. For items you generate in `$this->items`, only `uri` and `title` are mandatory in each item. `timestamp` and `content` are optional but recommended. Any additional key will be ignored by ATOM feed (but outputed to jSon).
|
||||
* To implement a new rss-bridge, create a new class in `bridges` directory and extends with `BridgeAbstract`. Look at existing bridges for examples. For items you generate in `$this->items`, only `uri` and `title` are mandatory in each item. `timestamp` and `content` are optional but recommended. Any additional key will be ignored by ATOM feed (but outputed to jSon). If you want your new bridge appear in `index.php`, don't forget add annotation.
