* (org-babel-header-args:maxima): Document the two new header
arguments (batch and graphics-pkg) that are specific to ob-maxima.
* (org-babel-maxima--command-arguments-default): A new variable
storing the default command-line argument(s). This value was
hard-coded in `org-babel-maxima:execute'.
* (org-babel-maxima--graphic-package-options): A new variable that
stores an alist of Maxima graphics packages and the Maxima code to set
up that package.
* (org-babel-maxima--default-epilogue): A new variable that stores an
alist of the clean-up code that is run at end of a `graphical-output'
or `non-graphical-output' source block.
* (org-babel-maxima--output-filter-regexps): A new variable that
stores a list of regexps to identify "bad" output lines to be removed
from Maxima's output. Source-code comments document each regexp's
purpose. Two additional regexps have been added: one filters
un-wanted output from `batch' and the other removes empty input lines
that `batch'-ed output may spuriously produce (actual empty input
lines are syntax errors, see the new tests below).
* (org-babel-maxima--output-filter): A new function that takes a
single line of Maxima output. It returns nil if the line has zero
length or matches a regexp in
`org-babel-maxima--output-filter-regexps'; otherwise, it returns the
line. This function and regexp replace the hard-coded filter in
`org-babel-execute:maxima'.
* (org-babel-maxima-expand): Prepare the source block for execution,
depending on whether it is producing graphical output or not. In case
of graphical output, use the `graphics-pkg' header to set the graphics
package and use `org-babel-maxima--graphic-package-options' to set-up
the package. Grovel the graphics terminal from the output filename.
* (org-babel-execute:maxima): Use the :batch header argument and
`org-babel-maxima--command-arguments-default' to execute the source
block. Replace the existing, in-line output filter and its regexps
with `org-babel-maxima--output-filter' and
`org-babel-maxima--output-filter-regexps'.
* testing/examples/ob-maxima-test.org: Add test examples.
Include examples of the batch-related tests from
testing/lisp/test-ob-maxima.el. Provide an example of the
`:graphics-pkg' header argument with the `draw' package.
* testing/lisp/test-ob-maxima.el: Introduce six new, batch-related
test functions. Each test exercises the :batch header argument. The
response to unusual inputs is tested (empty strings, strings with just
whitespace, input with the `:lisp' reader, and two syntax-related
errors).
