                else return true // continue inject step
            }
        )
    )

Notice: File object is a vinly stream.

• Template syntax:

Inject tag syntax in the format of:

<!--here[:namespace]:regex_match[??query]--><!--here-->

Support queries:

• inline Inline file contents to HTML, default false

• wrap HTML tag wrapper HTML tag for resource contontent, default true.Using with inline only.

For example:

<!-- here:asserts_here:\.html$??inline&wrap=false --><!-- /here -->

Inline resources:

Notice: query will be passed to sort and transform method as options.

<!-- here:\.css$??inline --><!-- /here -->

Namespace match(matching with "options.name" if given):

<!-- here:namespace:\.css$ --><!-- /here -->

More complex matching regexp:

<!-- here:\.(css|js|jsx)$ --><!-- /here -->

• Extname mapping:

Using here.mapping(from, to) to map extension of resource for reusing default wrapper when injecting:

here.mapping('ejs', 'html')
    .mapping('less', 'css')
