[BUG] Problems with :exports results for shell and plantuml code [9.6-pre (release_9.5.5-995-g4b9aef @ /home/dzu/.emacs.d/straight/build/org-mode/)]

[Detlev Zundel]

Hi orgmode-list!

I currently have a problem while exporting org-babel blocks to html or
latex output.  Even though I explicitely specify ':exports result' for
the blocks, the exported document contains both the (syntax colored)
code block and the code.  I noticed this in a plantuml block that I use
to generate inline diagrams.  Exporting to PDF actually yields a PDF
looking like it contains only the results, but there are errors in the
'*Org PDF LaTeX Outupt*' buffer, saying that pygmentize misses a lexer
for plantuml.  Checking the generated LaTeX code indeed shows that the
code is exported to LaTeX, even though ':exports result' is passed as a
header argument.

Trying to narrow this down to a simple recipe to reproduce the buggy
behaviour, I encountered another behaviour I don't understand.  Using a
simple 'sh' code block also with ':exports result' works for 'date', but
not for 'pwd'.  Yes, I know that the one is a builtin and the other is
an external command, but I did not expect this to be of any relevance when
':exports result' is used.

So the question is - am I doing something wrong here, or what should I
do to only export the resulting output of the commands into the
document?

Please find the test case attached - if exported to html or pdf, it
shows the problematic output: 'pwd' is included as code, 'date' is not
and 'plantuml' renders errors in the LaTeX run.

Any hint greatly appreciated!

Best wishes
  Detlev
