问题

I understand that Pug does not support dynamic includes or extends in templates. Ie

extend path/to/template

works but not

extend #{dynamic_path_to_template}

Is there a workaround (however convoluted) that will allow the same goal of modifying the template used by a view at runtime

Context: My use case is that I am developing an npm module and the template being used to extend other views is located inside the module. After the module is published and installed, the path will be defined (ie. node_modules/my_module/path/to/template) but during the development phase, I need to just be able to "npm link" to the module and have the templates work. I also would prefer not to hard code the links so I can publish the same code as tested.

There is no way to do this for now, but you can work out your application architecture without dynamic extends.

Possible solution #1

Make a layout.jade that conditionally include multiple layouts:

layout.jade:

if conditionalVariable
    include firstLayout.jade
else
    include otherLayout

In your view, extend layout.jade, and define conditionalVariable in the controller (true/false):
```
view.jade:

extends layout

block content
    p here goes my content!
```

Possible solution #2

Pass configurations to the layout

- var lang = req.getLocale();
doctype html
   block modifyLayout

split the project into multiple entrances, each entrance extends the layout and passes its different configs, and includes different things in different blocks
```
extends ../layout
block modifyLayout
   - var lang = "en" //force language to be en in this page.
block body
   include my-page-body
```
