A while back I declared war against what I call "tunneling" i.e., the
typical programmer practice of just working along on something without
making any sort of notes or comments . . . and that day's "Werdegang" as
they say in German (steps, procedure, process?) being only as good as your
memory of it. I see org mode as capable of is beating tunneling by actually
writing a story of your day's work inside an org-mode file.
For example, I'm working on a database project where I'd like to do lots of
emacs regex to get a file of comma delimited lines turned into sql
INSERT-ready statements. Here's what the VALUES of my INSERT look like:
(UPPER (SUBSTRING(MD5(RAND()) FROM 1 FOR 6)), ,'P',1)
the first part up until ...FOR 6)) is just a six-place hex id generator
(mysql syntax) for the record, then comes an empty field, then 'P' etc. So
I'm looking to shove a chunk of text from my comma delimited file into the
empty field. e.g.,
(...FROM 1 FOR 6)),'new thing 1','P',1)
where 'new thing 1' came from a line in the comma delim file. Right, so I
can do this with Emacs' regex in a one-off tunneling sort of way, but how
could I do this inside an org-mode file? I'm guessing I would need to use
elisp (perl, lisp, etc) in a literate way, i.e., my org-mode file would
have code sections and results sections. But could the results of running
literate code then be fed into the next section of literate code? I need to
run code on data, get results, run more code on that -- all while
interactively composing my org-mode file. Is this possible?
Basically, I'm looking for something better than the typical Emacs REPL
session where you have the option of simply saving the entire session's
REPL buffer. But I don't want it to be so cumbersome that I'm writing a
tutorial, either -- even though that's what I'm sort of doing. The dream
would be that a whole day's work could be contained in org-mode files --
both the code and the description of what's going on and how things came
(in)to be(ing).

When learning about [[http://software-lab.de/doc/ref.html][PicoLisp]] I
noticed that some of the very best programmers actually prefer just
reading code with minimal distraction by comments, so 'tunneling' is
probably not bad per se but rather a question of taste.

When its about programming work with just one language, you might try
outshine.el with outorg.el, if you work with several languages or its
more about publishing then actual programming, Org (Babel) should be
perfectly capable to do what you want.

Definitely, see this section of the manual:
(info "(Org) Noweb reference syntax")
