suppressing console output

suppressing console output

[Lars Huttar]

Hello,

I'm running context mkiv, version: 2013.05.28 00:36 (from the 2013 TeX
Live CD).
We're getting floods of output from context, including lots of Underfull
hboxes, and the names of .tex files that are being opened and closed.
This is all within a build script that does several other things besides
running context.
I'd like to suppress non-critical output from context so that other
important output from the script doesn't get so easily lost.
I'm already logging that output to a file, but I'd like to be able to
take advantage of the console as well.

I've tried the following command-line options to context, as suggested
by context --help:
--batchmode
--silent
--silent=typesetting
--noconsole

but none of these seem to have any effect on the output!
I could just have the script discard stdout from context; I'm not sure
how much of the output that would get rid of, but it may be good enough.
However it's not ideal.
(When an error occurs, as sometimes happens, I don't want the error
message and its context to be hidden while the console waits for the
user to respond blindly. I assume that would be on stderr anyway though...)

Can anyone tell me how to suppress non-critical messages from context as
it runs?

Thanks,
Lars

There are two types of messages that ConTeXt generates: Messages that come 
from TeX engine and messages that come from ConTeXt macro code. If you use

context --noconsole filename

the messages from ConTeXt are suppressed. I don't know of a way to 
suppress messages that originate from TeX engine.

And what about these messages:

context --noconsole test

currently there is no callback for open/close file message but at some 
point we can also intercept these (low priority, to be done when the 
luatex io is cleaned up)

Thanks.
In our case these amount to pages and pages of output, because our
document consists of many many files that reference each other
(including images). So I would vote a big +1 for that change.

doesn't --batchmode help then?

My mistake... --batchmode does seem to get rid of the file open/close
messages. (Until I learned that --noconsole takes an argument, there was
still so much output that it was hard to see a difference in output due
to --batchmode.)

Unfortunately, --batchmode also seems to suppresses printing fatal error
messages and stopping on them (as its --help documentation suggests). So
when the tex code has an error, the compilation continues to the end
(wasting significant time) and then exits with a failure status code,
but no indication of where the error occurred.

So --batchmode doesn't really seem to be an option for us.
Unless we use batchmode most of the time and then rerun without
batchmode after an error occurs.

I tried having the build script discard stdout from the context process
(with --noconsole=tmp.log but without --batchmode). But apparently, the
error output of context goes to stdout instead of stderr: Context stops
on a fatal error but the error message and prompt are lost, and the
process hangs, waiting for the user to respond to a message they can't see.

Normally more runtime is lost as side effect of (inefficient) settings 
than by messages to the console -)

How many pps do you get in a run? What kind of hardware?

Thanks, Aditya. I will try adding a filename argument.
This does seem to get rid of a lot of non-critical output, though not
all, as you noted in your followup email.

Is there any documentation about what kinds of complaints this
suppresses? I couldn't find any in the usual places. Apparently it is a
ConTeXt command rather than a primitive TeX one.

\show\dontcomplain

if console output is slowing down a run make sure you have an efficient 
console (i use conemu on windows and on unixes i always make sure that i 
use a proper font); sometimes you can set delays (standard cmd on 
windows is char-by-char but there are variants); when one runs from an 
editor normally the drawbacks are neglectable (at leats in scite)

Thanks, the slowdown is one of our concerns. I will look into
alternative terminals.

a simple \dorecurse can help to test it


\starttext
\dorecurse{1000}{test\page}
\stoptext

\starttext
\dorecurse{1000}{\input tufte\page}
\stoptext
