Hello other org mode aficionados! (I apologize for the errant email I
send a minute ago. )
I have created a (possible) patch to the export (ox.el and other
ox-XXX.el) files that allow for "source code" and "example" blocks to
have line numbers starting at an arbitrary number. Before the
(wonderful) ox redesign I used to have advice around some functions. I
hadn't needed this functionality for a while, but now that I did I
thought I would share.
The code is written with the following design:
-n is the same as -n 1 : The functionality is unchanged
+n is the same as +n 1 : The functionality is unchanged
-n X will "reset" and start new code block starting at line X
+n X will "add" X to the last line of the block before.
========
example:
* Heading 1
* ~-n 10~
#+BEGIN_SRC emacs-lisp -n 10
(save-excursion ;; This is line 10
(goto-char (point-min))) ;; 11
#+END_SRC
* ~-n~
#+BEGIN_SRC emacs-lisp -n
(save-excursion ;; line 1
(goto-char (point-min))) ;; line 2
#+END_SRC
* ~+n 155~
#+BEGIN_SRC emacs-lisp +n 155
(save-excursion ;; line 157
(goto-char (point-min))) ;; line 158
#+END_SRC
Gives the following "Text - ascii output"
1 Heading 1
===========
* `-n 10'
,----
| 10 (save-excursion ;; This is line 10
| 11 (goto-char (point-min))) ;; 11
`----
* `-n'
,----
| 1 (save-excursion ;; line 1
| 2 (goto-char (point-min))) ;; line 2
`----
* `+n 155'
,----
| 157 (save-excursion ;; line 157
| 158 (goto-char (point-min))) ;; line 158
`----
I have tested the code (using make test) and generated (hand verified)
the LaTeX and HTML output. ODT has an issue already with +n in that each
code block starts at line 1. (I did not address that).
I have included the git format patch output.
This is a fairly small set of changes, but I do assign the Copyright to
the Free Software Foundation.
Thanks,
