Hello,
Currently, a back-end is a symbol which may point to an entry in
`org-export-registered-backends' variable. Therefore a back-end must be
registered (with a unique name) before one can call it. Or, to put it
differently, it is impossible to use an anonymous and temporary
back-end.
This is not satisfying for developers, as there are situations when you
need to use a one-shot back-end but don't want to clutter registered
back-ends list. You can of course let-bind
`org-export-registered-backends' to something else, but it leads to
clunky code. The process should be abstracted a bit more.
The following (long) patches address this by defining back-ends as
structures (see `defstruct'), possibly anonymous and by separating
creation from registration process. It allows to quickly create and use
temporary back-ends. In the example below, we quickly export a string
using a temporary back-end:
(org-export-string-as
"* H1\n** H2\nSome string"
(org-export-create-backend
:transcoders
'((headline . (lambda (h contents i)
(let ((m (make-string (org-export-get-relative-level h i) ?=)))
(concat m " " (org-element-property :raw-value h) " " m "\n"
contents))))
;; Contents only.
(section . (lambda (e c i) c))
(paragraph . (lambda (e c i) c)))))
It is also possible to create a temporary derived back-end. The
following export will use registered `latex' back-end, excepted for
`bold' type objects.
(org-export-string-as
"Some *bold* /string/"
(org-export-create-backend
:parent 'latex
:transcoders '((italic . (lambda (o c i) (format "\\texit{%s}" c)))))
'body-only)
Besides `org-export-create-backend', tools provided are:
- `org-export-get-backend'
- `org-export-register-backend'
- `org-export-get-all-transcoders' (handles inheritance)
- `org-export-get-all-options' (handles inheritance)
- `org-export-get-all-filters' (handles inheritance)
At a higher level, `org-export-define-backend' and
`org-export-define-derived-backend' do not change (they are equivalent
to create and register in a row). So this change only matters for
back-end developers who used advanced features like
`org-export-with-translations' (which should now be
`org-export-with-backend' coupled with an anonymous back-end).
Also, it leads to a cleaner implementation as it removes the confusion
between a back-end and its name.
The next step after applying this patch will be to make
orgtbl-to-BACKEND functions use anonymous functions in order to
support :splice property, which is tedious with the new export
framework.
Feedback welcome.
Regards,

Subject: [PATCH 1/2] ox: Change back-ends internal representation to
structures
* lisp/ox.el (org-export--registered-backends): Renamed from
`org-export-registered-backends'.
(org-export-invisible-backends): Removed variable.
(org-export-get-backend, org-export-get-all-transcoders
org-export-get-all-options, org-export-get-all-filters): New
functions. It replaces `org-export-backend-translate-table'.
(org-export-barf-if-invalid-backend, org-export-derived-backend-p,
org-export-define-backend, org-export-define-derived-backend):
Rewrite functions using new representation.
(org-export-backend-translate-table): Remove function.
(org-export-get-environment): Use new function.
(org-export--get-subtree-options, org-export--parse-option-keyword,
org-export--get-inbuffer-options, org-export--get-global-options,
org-export-to-buffer org-export-to-file, org-export-string-as
org-export-replace-region-by): Update docstring.
(org-export-data-with-translations): Remove function. Use
`org-export-data-with-backend' with a temporary back-end instead.
(org-export-data-with-backend, org-export-as): Reflect new definition
for back-ends.
(org-export--dispatch-action, org-export--dispatch-ui): Reflect new
definition for back-ends and variable removal. Refactoring.
(org-export-filter-apply-functions): Call functions with
current back-end's name, not full back-end.
* lisp/org.el (org-export-backends, org-create-formula--latex-header):
Use new structure and variables.
* testing/lisp/test-ox.el: Update tests.
This patch separates back-end definition from its registration. Thus,
it allows to use anonymous or unregistered back-ends.

Subject: [PATCH 2/2] Export back-ends: Apply changes to back-end structure
* lisp/ox-html.el (org-html--format-toc-headline): Make use of
anonymous back-ends.
* lisp/ox-odt.el (org-odt-footnote-reference): Make use of anonymous
back-ends.
(org-odt-format-label, org-odt-toc, org-odt-format-headline--wrap):
Use `org-export-with-backend' instead of
`org-export-with-translations'.
* contrib/lisp/ox-freemind.el (org-freemind--build-node-contents): Use
`org-export-with-backend' instead of `org-export-with-translations'.

Its almost exclusively an internal change. Only the removal of
`org-export-with-translations' might bite back-end developers, but
I would be surprised if this feature was used in the wild.
I applied the patches. Now, onto orgtbl-to-*.

Is there anything that backend developers (both in core and contrib/)
should change in their code?

I don't think so. AFAICT, the only changes needed were in
ox-html/ox-odt/ox-freemind; I took care of them.
Again, you only need to change something if
`org-export-with-translations' appears in the code. See
758a545fb6da5e3314d609472c0defcee05cf703 for examples.

Okay, thanks.
(This is `org-export-data-with-translations', for those who
check this thread.)
I checked and no exporter uses this right now.

Here is an example illustrating the new features provided by quick and
anonymous export back-ends:
#+begin_src emacs-lisp
(defun my-orgtbl-to-csv ()
"Insert a comma separated version of Org table at point.
The table will be inserted at the end of the buffer. This
function makes no assumption about the major mode in the current
back-end."
(interactive)
(unless (org-at-table-p) (user-error "Not at an Org table"))
(require 'ox-org)
(let ((table
(org-export-string-as
;; Export the following table...
(buffer-substring-no-properties (org-table-begin) (org-table-end))
;; ... with the following back-end.
(org-export-create-backend
:parent 'org
:transcoders
'((table . (lambda (table contents info) contents))
(table-row . (lambda (row contents info)
;; Ignore table separators.
(and (eq (org-element-property :type row) 'standard)
(concat contents "\n"))))
(table-cell . (lambda (cell contents info)
(let ((field (org-quote-csv-field contents)))
(if (org-export-get-next-element cell info)

field))))))
;; Focus on the table only.

;; Insert TABLE at an appropriate location. For the sake of

(goto-char (point-max))
(insert table)))

Thanks for this!
Funnily enough, I had to export a table in CSV format just last week and
this function would have been great. As it is, a simple regex
replacement did the job but just not as elegant...

Well, you do have
M-x org-table-export RET table.csv
and it exports to csv already...

Arggghhh. Yes, this is there. I missed it because I did not give a
.csv file name; I gave a file name without extension for some
reason. It seems that the export command's options for format depend on
the name of the file so I was only given an export to TSV option.
Playing around now, it seems that if any extension is given (I tried
.csv, .data, .txt, .blah, .foobar), then export-to-csv is the
default. If no extension is given, export-to-tsv is the only
option. Not what I expected!
Thanks,
eric

See the docstring the `org-table-export'.
You can change the default table export format with either
`org-table-export-default-format' or TABLE_EXPORT_FORMAT.
