Inline files.


collection.inline() string collection.inline(wrap bool) string collection.inline(wrap bool, context File, request File, response File) string


wrap bool

Wrap each file in unique div to make client-side tools make them responsive.

context File

Reference the context of the request - the page being visited. It defaults to the context file of the current transaction.

request File

The request file that holds all input data, typically provided by the HTTP request, but may be modified by the callee, particularly for testing purposes. It defaults to the request file of the current transaction.

response File

The response argument is a reference to the file that shall be decorated with response metadata like statusCode, location or the head string attribute. It defaults to the response file of the current transaction.


Inline a collection of files via running their respective .Inline methods. All files to be inlined are run in separate isolated VMs.

The merged response bodies are returned after inlining all files in the collection.

Note that before .inline() returns the results, Boomla applies, some post processing like namespacing CSS class selectors.

The location and statusCode fields of the response body are also merged respecting the following rules:

  • For 3xx statusCodes, the location string attribute must be set.
  • If the location string attribute is set and the statusCode is left unchanged, the statusCode will default to 303.
  • A 5xx statusCode takes precedent over any statuscode < 500.
  • A 4xx statusCode takes precedent over any statuscode < 400.
  • A 3xx statusCode takes precedent over any statuscode < 300.
  • The statusCode 0 and 200 are equivalents.
  • If a statusCode is returned by a child transaction that falls within the same range (3xx, 4xx, 5xx) as already defined for the response file, that of the response file is not changed.


Simple example of 2 files returning hello world. Note that the response is wrapped in a div so that client-side tools can make it responsive.

Same example as above with all arguments specified.

Do not wrap children

Child throws an error.

Pass on head tags. Note that the response file is passed to collection.inline(), and so it is decorated with the head tags requested by the children. If you pass a different file instead of response, that file will be decorated instead.

Merge head tags for all.

If any child returns a status-code higher than that of the response file, the response file is updated.
