I have defined expand and execute functions for 'text' source blocks as follows:

(defun org-babel-expand-body:text (body params)
  (org-trim body))

(defun org-babel-execute:text (body params)
  (org-trim body))

I do this so that I can create basic templates for things like css, html, and configuration files. I want to use clojure to manipulate the text defined in these blocks as a string. For example, here I want to turn the output of the "sample" block into a clojure string in the "clojure-sample" block:

#+NAME: sample
#+begin_src text


#+RESULTS: sample
: some
: text

#+NAME: clojure-sample
#+begin_src clojure :noweb yes :results pp

But when I run org-babel-expand-src-block on the "clojure-sample" block, it expands to:


Why this is not being expanded into a single string and how I might fix it?

These are the expand and execute definitions for clojure source blocks.

(defun org-babel-expand-body:clojure (body params)
  "Expand BODY according to PARAMS, return the expanded body."
  (let* ((vars (org-babel--get-vars params))
         (result-params (cdr (assq :result-params params)))
         (print-level nil)
         (print-length nil)
           (format "%s"
                   ;; Variables binding.
                   (if (null vars) (org-trim body)
                     (format "(let [%s]\n%s)"
                              (lambda (var)
                                (format "%S (quote %S)" (car var) (cdr var)))
                              "\n      ")
    (if (or (member "code" result-params)
            (member "pp" result-params))
        (format "(clojure.pprint/pprint (do %s))" body)

(defun org-babel-execute:clojure (body params)
  (let ((expanded (org-babel-expand-body:clojure body params))
    (response (cons 'dict nil)))
    (let ((result-params (cdr (assoc :result-params params))))
      (setq response (nrepl-sync-request:eval expanded
      (setq result (concat (nrepl-dict-get response
                       (if (or
                        (member "output" result-params)
                        (member "pp" result-params))
               (nrepl-dict-get response "ex")
               (nrepl-dict-get response "root-ex")
               (nrepl-dict-get response "err")))
      (org-babel-result-cond (cdr (assoc :result-params params))
    (condition-case nil (org-babel-script-excape result)
      (error result))))))

I got what I wanted to work by changing the text expand function to

(defun org-babel-expand-body:text (body params)
  (replace-regexp-in-string (regexp-quote "\n") "\\n" (org-trim body) nil 'literal))

A clojure source block will then expand a text source block in the way where it can be interpreted as a string and can be spit to a file.
