Hi!
ConTeXt can detect issues in the sources and report them on the
console with the argument --errors or with \enabledirectives
[logs.errors]. The return value is still “0” (=success) even with
errors present.
Right now I use a script that parses the log file and lets me know
if a run has issues. However, it would be great if context could
return a non-zero value if errors are present. I've found that
\enabledirectives
[logs.errors=missing characters]
returns “1” if characters are missing. Lovely!
Undefined control sequences always return 1 (a TeX thing I believe
and not related to the macro package). But undefined control
sequences don't show up on the console as the other errors do if
general output (except errors) is silenced e.g. with
context --silent --noconsole --nostatistics --errors <file>
The question is, what other directives can be enabled that make
context return a failure? Is there a way to return failure if *any*
error is encountered or do they need to be enabled each
individually? And is there a way to show hard TeX errors as
undefined control sequences as a “possible issue” if output is
silenced?
MWE:
%% enables logging of errors same as --errors AFAIK
\enabledirectives
[logs.errors]
%% makes context return 1 on missing chars, great!
%% \enabledirectives
%% [logs.errors=missing characters]
\starttext
%% missing characters
𝒜
%% missing figure
\externalfigure [foo]
%% \end occurred inside a group at level 1
%% ### semi simple group … entered at line
\startalignment [middle]
foo
%% missing references
See \in{section}[sec:none].
%% undefined control sequence
%% \undefined
\stoptext

Hi Hans,
a followup to our conversation in the meeting: here's an MWE
demonstrating that errors aren't passed on to the runner script,
except for "logs.errors=missing characters", which in fact do return
failure, all others do return success.
%% enables logging of errors same as --errors
\enabledirectives
[logs.errors]
\starttext
%% ### semi simple group … entered at line
\startalignment [middle]
foo
\stoptext

You can check in the next upload:
- The 'failure' that you saw was actually a real lua error because I
hadn't adapted some fancy, a very old 'around' 2006 feature, seldom used
as it's more 'an example of possibilities' code to luametatex yet ...
fwiw, we still share some lua files between engines.
- Afaiks you should now get return code 1 for other cases (say you give
\foo without meaning). It's a it tricky as this info has to pass through
several subsystems.
- The runaway error is actually kind of special (there are a few more)
where the engine simply quits in confusion and doesn't exit hard as
error (often because tex could somehow recover). If needed I can
actually do a real error but it's not entirely compatible then (not that
i care that much about compatibility in these shady areas.)

Thanks for looking into that. I'll check the next upload.

Hard TeX errors (like \undefined) already return 1.

I'd vote to handle those as hard errors because
1) Luametatex isn't focused on compatibility.
2) The user explicitly requested error reporting (by providing --errors).
3) No one is recovering tex runs these days.

ok, but let's first test this ... it's mostly cosmetics (read: come up
wiht a better error message than the default sometimes unclear tex one)

indeed, makes no sense (it all dates from (paper) terminals and
night-time runs .. the good old 300 baud transfer days)

A solution is to use patterns (supported in the upcoming upload):
\enabledirectives
[logs.errors=*]
Alternatively use a compile-time switch:
context --errors='*' <file>
This will make the return value reflect the presence of an error.
