Eric Schulte 4b6d270b16 org-babel: bug fix, now possible to evaluate source blocks before the first heading 2009-11-20 19:38:23 -07:00
Eric Schulte 5b749d2fe9 org-babel: fixing documentation of `org-babel-tangle-langs' 2009-11-20 10:43:15 -07:00
Eric Schulte 222f5c23e8 org-babel: results are now foldable
pressing tab while on the front of a results line will fold the
  results in the same manner as tabbing on the front of a block will
  fold the block.  To automatically hide all blocks when entering a
  new file add the `org-babel-result-hide-all' function to your
  `org-mode-hook'

Eric Schulte 45cce02402 org-babel: caching bugfixes
- the match-string was thrown off by an earlier commit
  - now sorting the parameters to ensure consistent order when
  - generating hashes

Dan Davison 2f05cf41ff org-babel: allow header arg values to be lisp forms.
This allows e.g.

:file (format "%s/images/pca-scatter.png" dir)

Dan Davison bf6089d8de org-babel: allow aliases for #+lob
This introduces #+call as an alias for #+lob.
2009-11-20 10:42:53 -07:00
Eric Schulte 91661d2f3b org-babel: #+srcname: can now be called #+source: or #+function:
source name regular expression has been extracted into a variable
  and multiple aliases are allowed.

Eric Schulte 2f8d30a578 org-babel: now using #+results instead of #+resname
"results" is now an acceptable alias for "resname".  Org-babel
    will begin inserting results using the "results" option however
    either option will remain viable moving forward.

Eric Schulte f4f38bd33a org-babel: results hashes are now hidden (for the most part)
The initial `org-babel-hash-show' characters of the hash will
   remain visible.  Pressing C-c C-c with the point on one of these
   initial characters will copy the hash to the kill ring, should you
   need to know it for any particular reason.

Eric Schulte 403c92f676 org-babel: set default behavior to non-caching in `org-babel-default-header-args'
This can be overridden with the use of the header argument :cache on
  the block, or subtree level.  To set the global behavior to caching
  add the following to your emacs init

  (setq org-babel-default-header-args
        (delete '(:nocache) org-babel-default-header-args))

Eric Schulte 1453f0294d org-babel: Hash based caching of results in buffer
This commit expands the #+resname: line to include a sha1 hash of
  the contents of the source-code block (including header arguments).
  This hash is saved in raw text in the resname line.  When a source
  block is evaluated it's hash is recalculated and checked against the
  hash in it's results line, if they are equal the current results are
  returned with no recalculation.

  Optional prefix argument when evaluating a source block will force
  re-calculation.

  caching behavior can be inhibited through the use of the :nocache
  header argument.  for global inhibition of caching add :nocache to
  the `org-babel-default-header-args' variable.

Eric Schulte 4646bacfde org-babel-exp: fixed export bug
the problem is that we were searching back to the previous source
  block before source block execution.

Eric Schulte 1d2bab1fb8 org-babel: variable values are now indexable
it is now possible to only assign a portion of a value to a variable
  in a source block.  So for example the following will only assign
  the second and third lines of the table 'example-table' to the
  variable 'data'

  :var data=example-table[1:2]

  and the following will only assign the second column of the first row

  :var data=example-table[0,1]

  note that all indices are 0 based

  it is possible to index into the results of source-code blocks as
  well as tables.  any number of dimensions can be indexed as long as
  they are separated by ','s and ranges can be indexed using the ':'
  operator.  for more information on indexing behavior see
  `org-babel-ref-index-list'

Eric Schulte 56a81ee65a org-babel: no longer consumes src-block reference strings during export

  following src-block switches were being removed during export.

Dan Davison 6875d4d8e3 org-babel: file output for ruby and python
With this change, if :file <filepath> is specified, ruby and python
blindly output a link to <filepath>. Responsibility for creating the
contents in <filepath> lies with the python/ruby code.

Dan Davison c84903f1b3 org-babel: export of functional-style source blocks
A "functional-style" source block is one in which the name is followed
immediately by a parenthesised argument. An example is the following
"function", which generates n uniform random numbers:

\#+srcname: rand(n)
\#+begin_src R
runif(n)
\#+end_src

With these changes, such source blocks are passed over to the export
machinery in the following form:

\#+begin_src org-babel-lob
<function-def-keyword> rand(n):
\#+end_src
\#+begin_src R <switches>
<indent>runif(n)
\#+end_src

where <function-def-keyword> is the value of
org-babel-function-def-export-keyword, which defaults to "function",
<switches> are the src block switches that belonged to the original
block, and <indent> is the whitespace indent of the function body, the
width of which is determined by org-babel-function-def-export-indent.
org-babel-lob is a simple major mode responsible for fontification of
the blocks corresponding to the function definition line (as opposed
to the function body).

Dan Davison 75299025d6 org-babel: use org-babel-get-src-block-info during export 2009-11-01 10:05:42 -05:00
Dan Davison 872d9157d9 org-babel: include functional-style args in org-babel-get-src-block-info list
This adds a new terminal (sixth) element to the list returned from
org-babel-get-src-block-info. It is used when exporting the code of
"functional style" code blocks, i.e. those in which the name of the
block is followed by a parenthesised argument list (or an empty pair
of parentheses).

Dan Davison 72691f1ff7 org-babel: Single function to return all source block info.
- org-babel-get-src-block-info returns the name of the block as a new
  fifth element.

- org-babel-get-src-block-info incorporates the parenthesised variable
  references into the header arg list, with precendence given to
  explicit :var references, as before.

- remove function org-babel-get-src-block-name

- remove function org-babel-get-src-block-function-args

org-babel-get-src-block-function-args now returns a list
  (lang body params-alist switches srcname)
where, unless a non-nil value for the optional argument is passed,
params-alist contains any :var entries acquired from the parenthesised
argument list following the srcname.

Dan Davison dcc669f20a org-babel: parse src block switches
The switches are flags like -n and must *precede* the first colon
after the language (i.e. precede the first header argument). So the
general src block syntax is
\#+begin_src lang <switches> :header1 val1 :header2 val2 ...
...

org-babel-get-src-block-info now returns a list
(lang body params-alist switches)
