"Alist defining common header args and their allowed values.
|
|
|
|
Keys of the alist are header arg symbols.
|
|
Values of the alist are either a symbol `:any' or a list of allowed
|
|
values as symbols:
|
|
|
|
(header-name . :any)
|
|
(header-name . ((value1 value2 value3 ...))
|
|
(header-name . ((value1 value2 value3 ... :any))
|
|
|
|
When Org considers header-arg property inheritance, the innermost
|
|
value from the list is considered.
|
|
|
|
Symbol `:any' in the value list implies that any value is allowed.
|
|
Yet the explicitly listed values from the list will be offered as
|
|
completion candidates.
|
|
|
|
FIXME: This is currently just supported for `results' and `exports'.
|
|
Values in the alist can also be a list of lists. The inner lists
|
|
define exclusive groups of values that can be set at the same time for
|
|
a given header argument.
|
|
|
|
(results . ((file list ...)
|
|
(raw html ...))
|
|
|
|
The above example allows multi-component header arguments like
|
|
|
|
#+begin_src bash :results file raw
|
|
<:results will combine the two values \"file raw\".>
|
|
|
|
#+begin_src bash :results file list
|
|
<:results will only use the last value \"list\".>
|
|
|
|
#+property: header-args :results file html
|
|
...
|
|
#+begin_src bash :results list
|
|
<:results will inherit with partial override \"list html\".>

"Default arguments to use when evaluating a source block.
|
|
|
|
This is a list in which each element is an alist. Each key
|
|
corresponds to a header argument, and each value to that header's
|
|
value. The value can either be a string or a closure that
|
|
evaluates to a string.
|
|
|
|
A closure is evaluated when the source block is being
|
|
evaluated (e.g. during execution or export), with point at the
|
|
source block. It is not possible to use an arbitrary function
|
|
symbol (e.g. `some-func'), since org uses lexical binding. To
|
|
achieve the same functionality, call the function within a
|
|
closure (e.g. (lambda () (some-func))).
|
|
|
|
To understand how closures can be used as default header
|
|
arguments, imagine you'd like to set the file name output of a
|
|
latex source block to a sha1 of its contents. We could achieve
|
|
this with:
|
|
|
|
(defun org-src-sha ()
|
|
(let ((elem (org-element-at-point)))
|
|
(concat (sha1 (org-element-property :value elem)) \".svg\")))
|
|
|
|
(setq org-babel-default-header-args:latex
|
|
`((:results . \"file link replace\")
|
|
(:file . (lambda () (org-src-sha)))))
|
|
|
|
Because the closure is evaluated with point at the source block,
|
|
the call to `org-element-at-point' above will always retrieve
|
|
information about the current source block.
|
|
|
|
Some header arguments can be provided multiple times for a source
|
|
block. An example of such a header argument is :var. This
|
|
functionality is also supported for default header arguments by
|
|
providing the header argument multiple times in the alist. For
|
|
example:
|
|
|
|
((:var . \"foo=\\\"bar\\\"\")
|
|
(:var . \"bar=\\\"foo\\\"\"))")

By default RESULT is inserted after the end of the current source
|
|
block. The RESULT of an inline source block usually will be
|
|
wrapped inside a `results' macro and placed on the same line as
|
|
the inline source block. The macro is stripped upon export.
|
|
Multiline and non-scalar RESULTS from inline source blocks are
|
|
not allowed. When EXEC-TIME is provided it may be included in a
|
|
generated message. With optional argument RESULT-PARAMS controls
|
|
insertion of results in the Org mode file. RESULT-PARAMS can
|
|
take the following values:
|
|
|
|
replace - (default option) insert results after the source block
|
|
or inline source block replacing any previously
|
|
inserted results.
|
|
|
|
silent -- no results are inserted into the Org buffer but
|
|
the results are echoed to the minibuffer and are
|
|
ingested by Emacs (a potentially time consuming
|
|
process).
|
|
|
|
none ---- no results are inserted into the Org buffer nor
|
|
echoed to the minibuffer. They are not processed into
|
|
Emacs-lisp objects at all.
|
|
|
|
file ---- the results are interpreted as a file path, and are
|
|
inserted into the buffer using the Org file syntax.
|
|
|
|
list ---- the results are interpreted as an Org list.
|
|
|
|
raw ----- results are added directly to the Org file. This is
|
|
a good option if you code block will output Org
|
|
formatted text.
|
|
|
|
drawer -- results are added directly to the Org file as with
|
|
\"raw\", but are wrapped in a RESULTS drawer or results
|
|
macro, allowing them to later be replaced or removed
|
|
automatically.
|
|
|
|
org ----- results are added inside of a \"src_org{}\" or \"#+BEGIN_SRC
|
|
org\" block depending on whether the current source block is
|
|
inline or not. They are not comma-escaped when inserted,
|
|
but Org syntax here will be discarded when exporting the
|
|
file.
|
|
|
|
html ---- results are added inside of a #+BEGIN_EXPORT HTML block
|
|
or html export snippet depending on whether the current
|
|
source block is inline or not. This is a good option
|
|
if your code block will output html formatted text.
|
|
|
|
latex --- results are added inside of a #+BEGIN_EXPORT LATEX
|
|
block or latex export snippet depending on whether the
|
|
current source block is inline or not. This is a good
|
|
option if your code block will output latex formatted
|
|
text.
|
|
|
|
code ---- the results are extracted in the syntax of the source
|
|
code of the language being evaluated and are added
|
|
inside of a source block with the source-code language
|
|
set appropriately. Also, source block inlining is
|
|
preserved in this case. Note this relies on the
|
|
optional LANG argument.
|
|
|
|
list ---- the results are rendered as a list. This option not
|
|
allowed for inline source blocks.
|
|
|
|
table --- the results are rendered as a table. This option not
|
|
allowed for inline source blocks.
|
|
|
|
INFO may provide the values of these header arguments (in the
|
|
`header-arguments-alist' see the docstring for
|
|
`org-babel-get-src-block-info'):
|
|
|
|
:file --- the name of the file to which output should be written.
|
|
|
|
:wrap --- the effect is similar to `latex' in RESULT-PARAMS but
|
|
using the argument supplied to specify the export block
