Calling/using named babel code blocks

Calling/using named babel code blocks

I thought I understood "metaprogramming," i.e., creating generic code
blocks that can be called by any other code block regardless of programming
language -- but apparently I don't. I have this

 #+name: my-random-gen
#+header: :var n=0 :var lim=0
#+BEGIN_SRC emacs-lisp
(loop repeat n collect (random* lim))
#+END_SRC

and I have the variables initialized to zero. But now I don't know how to
call it with another code block. I've tried various versions of this

#+BEGIN_SRC emacs-lisp
my-random-gen(5 1.0)
#+END_SRC

and this various versions of this

#+BEGIN_SRC emacs-lisp :var results=my-random-gen() :var n=5 :var lim=1.0
results
#+END_SRC

to no avail. What am I missing? How can I actually use, call my-random-gen
in other code blocks?

Do these help?

#+BEGIN_SRC emacs-lisp :noweb yes
'<<my-random-gen(5, 1.0)>>
#+END_SRC


#+BEGIN_SRC emacs-lisp :var mrg=my-random-gen(5, 1.0)
mrg
#+END_SRC

I think you want:


#+name: my-random-gen
#+header: :var n=0 :var lim=0
#+BEGIN_SRC emacs-lisp
(loop repeat n collect (random* lim))
#+END_SRC

and this various versions of this

#+BEGIN_SRC emacs-lisp :var results=my-random-gen(n=5, lim=1.0)
results
#+END_SRC

#+RESULTS:
| 0.27765703201293945 | 0.7524830102920532 | 0.854852557182312 |
0.22202050685882568 | 0.604256272315979 |
