Ideally, it could be converted to a real Org table, but that's not the purpose of this posting. ** Other default case Here, I would like to take a look at the transactions which involve the unknown account: #+srcname: just-show-unknown #+begin_src ledger :cmdline reg unknown :noweb yes :session <> #+end_src #+results: just-show-unknown : 08-Jan-01 UNKNOWN-PAYEE Expenses:Unknown -21.91 EUR -21= .91 EUR Perfect result. That will serve as "demo". ** No output :PROPERTIES: :ID: 52aa2449-0c3d-4dee-ad57-8b2e916ed501 :END: #+srcname: no-output #+begin_src ledger :cmdline reg unkXXXnown :noweb yes :session <> #+end_src #+results: no-output ** Error neither trapped nor shown Let's imagine I thought (which was the case at some point) I needed to encl= ose the parameters between quotes: #+srcname: quoted-params #+begin_src ledger :cmdline "reg unknown" :noweb yes :session <> #+end_src #+results: quoted-params Nothing is returned. In fact, I would expect an error to be thrown, the same way it should when run in a shell: #+begin_src sh ledger -f journal.dat "reg unknown" #+end_src that is: : ~>ledger -f journal.dat "reg unknown" : Error: Unrecognized command 'reg unknown' :=20 : ~>echo $? : 1 Here, the shown results is exactly the same as in the [[id:52aa2449-0c3d-4d= ee-ad57-8b2e916ed501][No output]] case. As if the command ended successfully, with an empty results set... * Observations and suggestions I don't know if this is a common problem (to Org-Babel) or only to the Ledg= er part of it, but I think *we* should somehow improve the handling of errors. - Maybe displaying a =3D#+results-err=3D block which would be what's shown = on =3D/dev/stderr=3D, when not void? - And having a way to display the error code would be a plus.
