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).
- 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.
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)
noweb references which include ()s are now evaluated. It is
possible to pass arguments to the noweb references using the existing
lob argument syntax. So after this commit the following
<<example-block>>
will insert the body of "example-block", and the following
<<example-block()>>
will insert the results of "example-block", and the following
<<example-block(a=9)>>
will insert the results of "example-block" with argument "a" set to
the literal value of 9
This forces the #+lob regexp to match at the beginning of a line (with
optional preceding whitespace), and requires inline code blocks to be
surrounded by some whitespace.
1) source blocks can now reference source-blocks in other files using
the filename:sourcename syntax
2) on export all references are now made to explicitly point to the
original buffer using the filename:sourcename syntax. This ensures
that all references are correctly resolved on export, even when the
referenced source block has already been processed.
One half of this patch is a revert of c167a4ac32.
These changes are necessary so that :results output works correctly
with #+lob calls. For example the following example did not work:
--------------------------------------------------
3. :results output org -> doesn't work with #+lob:
--------------------------------------------------
\#+srcname: randthree(n,max)
\#+begin_src ruby
number = n
maximum = max
puts "* Random numbers\n" +
"Here are some random numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
\#+end_src
\#+lob: randthree(n=3,max=10) :results output org
This change allows org-file-properties to supply header args, and also
allows property inheritance if it has been enabled. Header-args
aquired from the item (or by inheritance) have precedence over those
aquired from org-file-properties.
This includes the required changes to org-babel.el and a
language-specific implementation for emacs-lisp. The emacs-lisp
changes are from a patch by Benny Andresen.
This allows python code to be tangled (i.e. extracted) correctly by
org-babel-tangle. Previously, if e.g. methods of a class were in
separate blocks, then they would be incorrectly indented as top-level
functions in the tangled output.
