Bug: src code blocks of type compilation-minor don't work when generating PDF [9.1.14 (9.1.14-dist @ /path/to/org/install/emacs/site-lisp/org/)]

Bug: src code blocks of type compilation-minor don't work when generating PDF [9.1.14 (9.1.14-dist @ /path/to/org/install/emacs/site-lisp/org/)]

[John Ciolfi]

Hi

Using following

  emacs -q --batch -L /path/to/org/install/emacs/site-lisp/org -l my-org-to-pdf.el

the generated PDF is incorrect. The "compilation-minor" code block gets
replaced with the "c" code block, i.e. the c code block is
duplicated. If you generate HTML all is good. Running org-lint doesn't
indicate that one cannot use compilation-minor code blocks.

I'm using Emacs 25.1.1 with the released version of org-mode
9.1.14. It would be nice if this was supported. Alternatively, if
compilation-minor (or compilation) code blocks are not supported could
and error be produced?

Thanks

Hi John,

Given that the produced foo.tex file looks correct, it seems that
since minted does not know what to do with the "compilation-minor"
"language", it goes off a cliff. If you compile it by hand:

   pdflatex --shell-escape foo.tex

it produces an error message:

,----
| (./foo.out.pyg) (./foo.out.pyg) (./foo.toc) (./foo.out.pyg)Error: no
| lexer for alias 'compilation-minor' found system returned with code
| 256 (./foo.out.pyg)
`----

but since it produces a (wrong) PDF, the org exporter does not dig any further.

Changing the language to "c" in the tex file (or in the
source block before re-exporting) produces something a bit better.
Ideally, you'd need to define a lexer for the "compilation-minor" "language",
but that's a minted/pygments project.

Not sure whether it's worth doing anything about this on the org mode side,
but that's not my call.

HTH.

PS. Constantine says "Hi" :-)
