Re: [O] (9.2) Noweb blocks not expanded in Python blocks : it should be a bug...
I doubt it is Python specific, and I don't know why it would work in some
places and not others. For me, the two character name does not work in
elisp, but 1 or 3 does. I agree that seems buggy.
The origin of the problem is here:
#+BEGIN_SRC emacs-lisp
(list
(string-match (org-babel-noweb-wrap) "<>")
(string-match (org-babel-noweb-wrap) "<>")
(string-match (org-babel-noweb-wrap) "<>"))
#+END_SRC
#+RESULTS:
| 0 | nil | 0 |
my regex fu is not adequate to identify the problem:
#+BEGIN_SRC emacs-lisp
(org-babel-noweb-wrap)
#+END_SRC
#+RESULTS:
: <<\([^
: ].+?[^ ]\|[^
: ]\)>>
That function is used in org-babel-expand-noweb-references.
It is somewhat luck that I found that, I was tracing
org-babel-expand-noweb-references to see where it was failing, and walked
through that line to see it failed on "Ah", and worked on longer names.

Indeed. Nice catch ; how did you find this ?
Since this doesn't happen with emacs-lisp or Sage, and since nothing in
the docs I've read so far suggests anything about the length of a block
identifier, I consider this a bug in the Python language support code.
What do you think ? Any hint ?
Thanks a lot !

The problem may be the name is only two characters long. Try Ahh instead.
That works for me.

[O] (9.2) Noweb blocks not expanded in Python blocks.
Seen in `org-mode' version `9.2'.
Using `noweb' syntax works OK with `emacs-lisp':
┌
│ #+name: a
│ #+begin_src emacs-lisp
│ (setq L (append L (list i)))
│ #+end_src
│
│ #+name: b
│ #+begin_src emacs-lisp :noweb yes :exports both
│ ;; Lisp version
│ (setq L nil)
│ (dotimes (i 5) <>)
│ L
│ #+end_src
└
This gives :
┌
│ (setq L (append L (list i)))
└
┌
│ ;; Lisp version
│ (setq L nil)
│ (dotimes (i 5) )
│ L
└
The `noweb' syntax also works with `Sage' (a symbolic maths oriented
Python derivative):
┌
│ #+name: Aaarghhh
│ #+begin_src sage
│ L.append(i)
│ #+end_src
│
│ #+name: Berde
│ #+begin_src sage :noweb yes :exports both
│ ## Python version
│ L=[]
│ for i in range(1,6):
│ <>
│ L
│ #+end_src
└
wich gives :
┌
│ L.append(i)
└
┌
│ ## Sage version
│ L=[]
│ for i in range(1,6):
│
│ L
└
But using the same syntax in Python fails miserably:
┌
│ #+name: Ah
│ #+begin_src python
│ L.append(i)
│ #+end_src
│
│ #+name: Beee
│ #+begin_src python :noweb yes :exports both
│ ## Python version
│ L=[]
│ for i in range(1,6):
│ <>
│ L
│ #+end_src
└
┌
│ L.append(i)
└
┌
│ ## Python version
│ L=[]
│ for i in range(1,6):
│ <>
│ L
└
┌
│ []
└
It *seems* that the "Ah" block is not expanded.
The code itself should be sound *if* it expanded:
┌
│ #+name: B0
│ #+begin_src python :exports both
│ L=[]
│ for i in range(1,6):
│ L.append(i)
│ L
│ #+end_src

Seen in ~org-mode~ version src_emacs-lisp{org-version}.
Using ~noweb~ syntax works OK with ~emacs-lisp~:
#+begin_example
#+name: a
#+begin_src emacs-lisp
(setq L (append L (list i)))
#+end_src
#+name: b
#+begin_src emacs-lisp :noweb yes :exports both
;; Lisp version
(setq L nil)
(dotimes (i 5) <>)
L
#+end_src
#+end_example
This gives :
#+name: a
#+begin_src emacs-lisp
(setq L (append L (list i)))
#+end_src
#+name: b
#+begin_src emacs-lisp :noweb yes :exports both
;; Lisp version
(setq L nil)
(dotimes (i 5) <>)
L
#+end_src
The ~noweb~ syntax also works with ~Sage~ (a symbolic maths oriented
Python derivative):
#+begin_example
#+name: Aaarghhh
#+begin_src sage
L.append(i)
#+end_src
#+name: Berde
#+begin_src sage :noweb yes :exports both
## Python version
L=[]
for i in range(1,6):
<>
L
#+end_src
#+end_example
wich gives :
#+name: Aaarghhh
#+begin_src sage
L.append(i)
#+end_src
#+name: Berde
#+begin_src sage :noweb yes :exports both
## Sage version
L=[]
for i in range(1,6):
<>
L
#+end_src
But using the same syntax in Python fails miserably:
#+begin_example
#+name: Ah
#+begin_src python
L.append(i)
#+end_src
#+name: Beee
#+begin_src python :noweb yes :exports both
## Python version
L=[]
for i in range(1,6):
<>
L
#+end_src
#+end_example
#+name: Ah
#+begin_src python
L.append(i)
#+end_src
#+name: Beee
#+begin_src python :noweb yes :exports both
## Python version
L=[]
for i in range(1,6):
<>
L
#+end_src
It *seems* that the "Ah" block is not expanded.
The code itself should be sound *if* it expanded:
#+begin_example
#+name: B0
#+begin_src python :exports both
L=[]
for i in range(1,6):
L.append(i)
L
#+end_src
#+end_example
#+name: B0
#+begin_src python :exports both
L=[]
for i in range(1,6):
L.append(i)
L
#+end_src
