org-babel:希望所有noweb块引用在导出时都显示为原样

Question

在org-mode中考虑以下MVE --它详细地包含了我的完整问题。但是，总而言之，对于一些代码块，当我导出文档时，一些对其他代码块的noweb引用会被内联替换，而对于其他代码块，noweb引用会被原封不动地复制到导出的PDF中。我不知道是什么导致了这种行为上的差异，我也不知道如何控制它，但我想这样做。我希望能够指定一些块具有行为1(引用被替换)，而其他块具有行为2(逐字引用)。

org-export生成的PDF是at this link。

#+BEGIN_COMMENT
The emacs lisp block must export results, even though the results are none,
otherwise the block will not be eval'ed on export, and we will get 
unacceptable confirmation requests for all the subsequent python blocks. 
#+END_COMMENT

#+BEGIN_SRC emacs-lisp :exports results :results none
(setq org-confirm-babel-evaluate nil)
#+END_SRC

** PyTests

   Define the test and cases. This code must be tangled out to an external file
   so =py.test= can see it.

   When I /export/ this to PDF, the noweb references, namely =<<imports>>= and
   =<<definitions>>=, are substituted inline, so the typeset version of this
   block in the PDF shows ALL the code.  This is not what I want.

#+NAME: test-block
#+BEGIN_SRC python :noweb yes :tangle test_foo.py 
<<imports>>
<<definitions>>
def test_smoke ():
    np.testing.assert_approx_equal (foo_func (), foo_constant)
#+END_SRC

#+RESULTS: test-block
: None

   The following blocks import prerequisites and do a quick smoke test:

** Do Some Imports

#+NAME: imports
#+BEGIN_SRC python 
import numpy as np
#+END_SRC

#+RESULTS: imports
: None

** Define Some Variables

   However, in the typeset PDF, the noweb reference =<<foo-func>>= in the block
   below is /not/ substituted in-line, but rather appears verbatim. I want /all/
   noweb references to appear verbatim in the exported, typeset, PDF document,
   just like this one.

#+NAME: definitions
#+BEGIN_SRC python 
foo_constant = 42.0
<<foo-func>>
#+END_SRC

#+RESULTS: definitions

** Define Some Functions

*** Foo Function is Really Interesting

#+NAME: foo-func
#+BEGIN_SRC python
def foo_func () :
    return 42.000
#+END_SRC

#+RESULTS: foo-func
: None

We want results from pytest whether it succeeds or fails, hence the /OR/ with
=true= in the shell

#+BEGIN_SRC sh :results output replace :exports both
py.test || true
#+END_SRC

#+RESULTS:

找到适当的references here

Here is a corrected PDF exported from the following .org file。

下面是修正后的MVE (它本身解释了修正)：

#+BEGIN_COMMENT
The emacs lisp block must export results, even though the exports are none,
otherwise the block will not be eval'ed on export, and we will get unacceptable
confirmation requests for all the subsequent python blocks.
#+END_COMMENT

#+BEGIN_SRC emacs-lisp :exports results :results none
  (setq org-confirm-babel-evaluate nil)
#+END_SRC

** PyTests

   Define the test and cases. This code must be tangled out to an external file
   so =py.test= can see it.

   When I /export/ this to PDF, the noweb references, namely =<<imports>>= and
   =<<definitions>>=, are *NOT* substituted inline, but typeset verbatim. This
   is what I want.  You get this behavior by saying =:noweb no-export= in the
   header.

#+NAME: test-block
#+BEGIN_SRC python :tangle test_foo.py :noweb no-export :exports code :results none
dummy_for_org_mode = True
<<imports>>
<<definitions>>
def test_smoke ():
    np.testing.assert_approx_equal (foo_func (), foo_constant)
#+END_SRC

   The following blocks import prerequisites and do a quick smoke test:

** Do Some Imports

#+NAME: imports 
#+BEGIN_SRC python :exports code :results none
  import numpy as np
#+END_SRC

** Define Some Variables and Functions

   In this block, I want the noweb reference =<<foo-func>>= in the block to be
   substituted in-line and not to appear verbatim. Do that by saying
   =:noweb yes= in the header.

#+NAME: definitions 
#+BEGIN_SRC python :noweb yes :exports code :results none
  foo_constant = 42.0
  <<foo-func>>
#+END_SRC

** Define Some Functions

*** Foo Function is Really Interesting

Here, I want to talk about the implementation of foo function in detail, but I
don't want its code to be exported again, just to appear in the original
=.org= file as I reminder or note to me.

#+NAME: foo-func 
#+BEGIN_SRC python :exports none :results none
  def foo_func () :
      return 42.000
#+END_SRC

** Run the Tests

We want results from pytest whether it succeeds or fails, hence the /OR/ with
=true= in the shell

#+BEGIN_SRC sh :results output replace :exports both
  py.test || true
#+END_SRC

#+RESULTS:
