* (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). link: https://list.orgmode.org/87cyz1ivzw.fsf@t14.reltub.ca/
