Here is the quick description: This lets you fetch tiddlers from other wikis online. The wikis can be on the same server or other servers. To use it, on your own wiki, enter a wiki url and a filter. Click on the Fetch button and the tiddlers from the wiki at the url given that match the filter are copied into your wiki. Both wikis involved need the plugin in order for this to work.
For demonstration, I have one wiki on my domain http://ooktech.com/jed/ExampleWikis/FetchTiddlers/ and I have one wiki on tiddlyspot http://tiddlerbundletest.tiddlyspot.com/ Remember, both wikis need the plugin so you won't be able to pull anything from another wiki unless you install the plugin on that wiki too. Be careful when doing that since to my knowledge me and mat are the only people who have done anything with this yet and there may be some bugs we haven't seen yet. The longer description: This was a mostly unplanned result of the tiddler bundles I have been working on and it still has some leftovers from that that I will change or remove soon. There are two wikis involved, I am going to call the one you control the local wiki and the wiki that you want to fetch things from the remote wiki. I made a new tiddler message based on how fetching plugins works, but instead of fetching existing objects it talks to the remote wiki and the remote wiki bundles the desired tiddlers together and sends the bundle. There are four steps to this: 1) The user of the local wiki triggers the tm-fetch-bundle wiki message, which uses postMessage and a hidden iframe to send a message to the remote wiki with information about the desired bundle 2) The remote wiki has a listener when receives the message and creates the requested bundle and then uses postMessage to send it back to the local wiki 3) The local wiki has a listener which receives the message from the remote wiki and adds the received bundle as a tiddler in the local wiki. 4) The hidden iframe is closed. The tiddlers are currently all bundled when sent so that the received object doesn't have any properties that will maliciously affect the receiving wiki. I need to change tiddler bundles so that they are displayed inside code blocks so none of the wikitext is rendered. I am hoping to add more to the messages passed between the wikis so that if desired the local wiki can just directly import a tiddler instead of a bundle, but for now I want to make things as safe as possible for users. Since nothing is saved until the user manually saves the wiki I don't think that the send bundle message can be abused, but as part of improving the messages I will probably add some very primitive authentication so you can set the local wiki to only accept bundles from approved remote wikis. And remote wikis can be set to only accept the bundle request if the local wiki has been approved. Since javascript is used for the negotiations we should be able to have pretty complex behaviour for requests and replies. This may be used as a way to make a multi-user wiki. Each user would have their own version and they would edit it however they like, then they would periodically fetch changes from the other users. We need to come up with some method of version control for this to work, but it should be a start. This last bit is a note that I should probably expand upon and put as an issue on github: I don't know if the close/reload plugin library problem has been solved, but if not than we should be able to apply how I close the iframe here to closing plugin libraries. Even if that isn't the case, how we handle plugin libraries needs to be made more generic so that the same mechanism can be reused for other inter-wiki communication. This isn't any big change, just a thought before we make other things that use the mechanism. Also as part of the re-factoring we should make it easier for plugin writers to add browser messages without needing to edit $:/core/modules/startup/browser-messaging.js -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
