The simplest type of JavaScript module to write for TiddlyWiki5 is a JS macro. The semantics are extremely simple: the macro defines the names of its parameters, and exports a handler function that is called when the macro is invoked. Here’s a simple example from the core: https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/macros/makedatauri.js <https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/macros/makedatauri.js> There are quite a few restrictions and limitations with macros, though. Firstly, a macro is not supposed to have any side effects (it cannot create or modify tiddlers, for example), and is supposed to return the same result every time it is called with a given set of parameters. Secondly, they don’t participate in the refresh mechanism (which is one of the things that makes them simple to write). This means that you can’t easily arrange for them to automatically refresh if underlying data should change. Nonetheless, in many situations, writing a macro is adequate. There is some documentation here: http://tiddlywiki.com/dev/#JavaScript%20Macros In your case, you could write a macro <<extract-regexp filter>> that would retrieve the tiddlers matching a filter, and retrieve the highlights from inside them, and then return the resulting regexp. Then, you could use an action-setfield widget within a button to allow the user to manually trigger the assignment of the regular expression to a tiddler. > 2.)

TiddlyWiki 5 provides a Common/JS compatible module loader that makes it easy to require() other modules and access their exports. Here’s an example from one of the core plugins: https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/widgets/button.js#L15 > Something else - I used to be able to get tiddlers into my macros with code > like "store.getTiddlerText" - does that functionality still exist? Can > someone point me to where it's documented? Within a macro, you can obtain the text of a tiddler with: this.wiki.getTiddlerText("HelloThere") TiddlyWiki’s internal APIs are only documented within the source. Most of the TiddlyWiki Classic store.*() functions will be found in: https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/wiki.js <https://github.com/Jermolene/TiddlyWiki5/blob/master/core/modules/wiki.js> Generally, the trick with TiddlyWiki 5 development is to find an existing plugin or module that you can use as a starting point.
