! Macro Fields
|
|
|
|
Macros are implemented as conventional JavaScript modules that export a single variable called `macro` that contains these fields:
|
|
|
|
|!Field Name |!Description |
|
|
|`name` |The name of the macro |
|
|
|`types` |An array of the MIME types that the macro can render |
|
|
|`params` |A hashmap of the parameters accepted by the macro (see below) |
|
|
|`events` |An optional hashmap of event handling functions (see below) |
|
|
|`render` |The macro rendering function (see below) |
|
|
|`rerender` |The optional macro rerendering function (see below) |
|
|
|`dependentAll` |True if the macro needs access to all available tiddlers |
|
|
|
|
! Macro Parameters
|
|
The `params` hashmap provides the following fields about each parameter:
|
|
|
|
|!Param Field Name |!Description |
|
|
|`byName` |Provided if the parameter should be referenced by name. The value can be `true` or `"default"` to indicate that anonymous parameters are acceptable |
|
|
|`type` |The type of the parameter, either `text` or `tiddler` (used for dependency tracking) |
|
|
|`rel` |The relationship for parameters of type tiddler - either "link" or "include" |
|
|
|`optional` |`true` if the parameter is optional |
|
|
|
|
! Macro Rendering
|
|
The `render` function should return the new text representation of the macro output. It is called with the following parameters:
|
|
|
|
|!Param Name |!Description |
|
|
|`type` |The target MIME type for rendering the macro |
|
|
|`tiddler` |The tiddler in whose context the macro is being rendered |
|
|
|`store` |The `WikiStore` object to be used |
|
|
|`params` |The macro parameters as a hashmap |
|
|
|`content` |The rendered text of the children of the macro |
|
|
|
|
!Macro Rerendering
|
|
The `rerender` function is called with the following parameters:
|
|
|
|
|!Param Name |!Description |
|
|
|`node` |The DOM node containing the existing rendering of the macro |
|
|
|`changes` |Hashmap of `{title: "created|modified|deleted"}` |
|
|
|`type` |The target MIME type for rendering the macro |
|
|
|`tiddler` |The tiddler in whose context the macro is being rendered |
|
|
|`store` |The `WikiStore` object to be used |
|
|
|`params` |The macro parameters as a hashmap |
|
|
|`content` |The rendered text of the children of the macro |
|
|
|
|
!Macro Event Handlers
|
|
Event handlers are called with the following parameters:
|
|
|
|
|!Param Name |!Description |
|
|
|`event` |The DOM node containing the existing rendering of the macro |
|
|
|`node` |Hashmap of `{title: "created|modified|deleted"}` |
|
|
|`tiddler` |The tiddler in whose context the macro is being rendered |
|
|
|`store` |The `WikiStore` object to be used |
|
|
|`params` |The macro parameters as a hashmap |
|
|
|
|
Event handlers should return `false` if they handle the event (and generally should also call `event.preventDefault()`), and `true` if they do not.
