The main boot kernel for TiddlyWiki. This single file creates a barebones TW environment that is just
|
|
sufficient to bootstrap the modules containing the main logic of the application.
|
|
|
|
On the server this file is executed directly to boot TiddlyWiki. In the browser, this file is packed
|
|
into a single HTML file along with other elements:
|
|
|
|
# bootprefix.js
|
|
# <module definitions>
|
|
# boot.js
|
|
|
|
The module definitions on the browser look like this:
|
|
|
|
$tw.defineModule("MyModule","moduletype",function(module,exports,require) {
|
|
// Module code inserted here
|
|
return exports;
|
|
});
|
|
|
|
In practice, each module is wrapped in a separate script block.
