/** |
34
|
|
|
* The base class for all Hyde pages. |
35
|
|
|
* |
36
|
|
|
* To ensure compatibility with the Hyde Framework, all page models should extend this class. |
37
|
|
|
* Markdown-based pages can extend the BaseMarkdownPage class to get relevant helpers. |
38
|
|
|
* |
39
|
|
|
* Unlike other frameworks, in general you don't instantiate pages yourself in Hyde, |
40
|
|
|
* instead, the page models acts as blueprints defining information for Hyde to |
41
|
|
|
* know how to parse a file, and what data around it should be generated. |
42
|
|
|
* |
43
|
|
|
* To create a parsed file instance, you'd typically just create a source file, |
44
|
|
|
* and you can then access the parsed file from the HydeKernel's page index. |
45
|
|
|
* The source files are usually parsed by the SourceFileParser action. |
46
|
|
|
* |
47
|
|
|
* In Blade views, you can always access the current page instance being rendered using the $page variable. |
