Subject: [PATCH] removing code block, results and call-line synonyms -- BREAKING CHANGE
Following a round of on-list discussion many code block synonyms have
been removed, moving forward the following syntax is valid.
- call lines are specified with #+call:
- code blocks are named with #+name:
- results are named with #+name:, however results generated by a code
block may still be labeled with #+results:, and tables named with
#+tblname: will be considered to be named results
The following function may be used to update an existing Org-mode
buffer to the new syntax.
(defun update-org-buffer ()
"Update an Org-mode buffer to the new data, code block and call line syntax."
(interactive)
(save-excursion
(flet ((to-re (lst) (concat "^[ \t]*#\\+" (regexp-opt lst t)
"\\(\\[\\([[:alnum:]]+\\)\\]\\)?\\:[ \t]*"))
(update (re new)
(goto-char (point-min))
(while (re-search-forward re nil t)
(replace-match new nil nil nil 1))))
(let ((old-re (to-re '("RESULTS" "DATA" "SRCNAME" "SOURCE")))
(lob-re (to-re '("LOB")))
(case-fold-search t))
(update old-re "name")
(update lob-re "call")))))
Note: If an old version of Org-mode (e.g., the one shipped with Emacs)
is installed on your system many of the important variables will
be pre-defined with a defvar and *will not* have their values
automatically updated, these include the following.
- org-babel-data-names
- org-babel-result-regexp
- org-babel-src-block-regexp
- org-babel-src-name-regexp
- org-babel-src-name-w-name-regexp
It may be necessary to either remove the source code of older
versions of Org-mode, or to explicitly evaluate the ob.el file.
* lisp/ob-exp.el (org-exp-res/src-name-cleanup): Updated
Documentation.
* lisp/ob-lob.el (org-babel-block-lob-one-liner-regexp): Updated
regular expression.
(org-babel-inline-lob-one-liner-regexp): Updated regular expression.
* lisp/ob-ref.el (org-babel-ref-resolve): Notice when something that
looks like a data results may actually be a code block.
* lisp/ob-table.el: Updated documentation.
* lisp/ob.el (org-babel-src-name-regexp): Simplified regexp.
(org-babel-get-src-block-info): Updated match strings.
(org-babel-data-names): Simplified acceptable names.
(org-babel-find-named-block): Indentation.
(org-babel-find-named-result): Updated to not return a code block as
a result.
* lisp/org.el (org-fontify-meta-lines-and-blocks-1): Removing
references to old syntactic elements.
(org-additional-option-like-keywords): Removing references to old
syntactic elements.
* contrib/babel/library-of-babel.org: Updated to make use of the new
syntax.
* testing/examples/babel-dangerous.org: Updated to make use of the new
syntax.
* testing/examples/babel.org: Updated to make use of the new syntax.
* testing/examples/ob-awk-test.org: Updated to make use of the new
syntax.
* testing/examples/ob-fortran-test.org: Updated to make use of the new
syntax.
* testing/lisp/test-ob.el: Removed two bad tests which tested the
literal values of old regular expressions rather than their
behavior.
Please consider a patch to construct a table from the output of maxima
code block.

Subject: [PATCH 2/2] Add tests for ob-C.el
* testing/examples/babel.org (an): Test the combination of code block
results wrapper and type.
* testing/lisp/test-ob.el (test-org-babel/combining-scalar-and-raw-result-types):
Test the combination of code block results wrapper and type.
* testing/examples/org-exp.org: Example file for export tests.
* testing/lisp/test-org-exp.el (test-org-exp/stripping-commas): List
file for export tests.
* lisp/ob-exp.el (org-babel-in-example-or-verbatim): Also check for in
verbatim emphasis.
(org-babel-exp-lob-one-liners): Cleaner checking for escaped call
lines.
* testing/examples/babel.org: Example data for new test.
* testing/lisp/test-ob-tangle.el
(ob-tangle/no-excessive-id-insertion-on-tangle): Safer to narrow,
and less work.
(ob-tangle/continued-code-blocks-w-noweb-ref): Testing new
:noweb-ref header argument.
Thanks to Charles C. Berry for insisting on this issues existence
This change is now secured with a unit test
* lisp/ob.el (org-babel-parse-header-arguments): Stripping trailing
spaces off of header arguments (even the first one).
* lisp/ob.el (org-babel-sha1-hash): now handles more complex types in
params
* testing/examples/babel.org: whitespace
* testing/lisp/test-ob.el (test-org-babel/sha1-hash): new test for
babel hashing
* lisp/ob-lob.el (org-babel-lob-execute): now expanding variable
references before execution
* lisp/ob.el (org-babel-merge-params): better indentation, and finally
sorted out the proper replacement of conflicting variable
definitions
includes a simple export test
* lisp/ob-exp.el (org-babel-exp-in-export-file): wrapper for
collecting information from within the original export file
(org-babel-exp-src-blocks): simplified through use of the above
macro
(org-babel-exp-code): simplified through the use of new functions
for parsing header arguments
(org-babel-exp-results): simpler high-level organization, also this
is now where the expansion of variable references takes place during
export
* lisp/ob.el (org-babel-expand-variables): broke variable replacement
in a parameter list into it's own function
(org-babel-get-src-block-info): now using the above function
for example, from the test of this functionality
* multi-line header arguments

| 1 | a |
| 2 | b |
| 3 | c |
| 4 | d |

| 7 | g |
* lisp/ob.el (org-babel-multi-line-header-regexp): new variable for
matching header lines preceding code blocks
(org-babel-src-name-w-name-regexp): now includes possible header
lines between source name and code block
(org-babel-get-src-block-info): now also collecting header arguments
from preceding header lines
(org-babel-src-block-names): updated match-string to reflect new
value of org-babel-src-name-w-name-regexp
