Package: maxima
Version: 5.41.0-3
Severity: normal
While writing a script for Maxima, I wanted to print output to stdout while
simultaneously printing debug output to stderr. I am reporting this as a debian
bug first because console I/O likely ties in to the underlying libraries and
build configuration.
In the documentation for the Maxima "printf" function it states:
> If dest is a stream or true, then printf returns false. Otherwise, printf
> returns a string containing the output. By default the streams stdin, stdout
> and stderr are defined.
However, the output I expected to go to stderr actually went to stdout instead.
Here is a one-liner to show the behaviour:
> maxima --very-quiet -r >maxima-stdout 2>maxima-stderr \
> 'printf(stdout,"stdout~%")$ printf(stderr,"stderr~%")$'
I expect two files: maxima-stdout should contain "stdout" and maxima-stderr
should contan "stderr". Instead, maxima-stdout contains both lines and
maxima-stderr is empty.
Starting up a Maxima session, stdout and stderr does not seem to mean anything
until using them with printf(). After doing that, I can print what stdout and
stderr are connected to:

> (%i1) stdout;
> (%o1) stdout
> (%i2) stderr;
> (%o2) stderr
> (%i3) printf(stdout,"Hello")$
> Hello
> (%i4) printf(stderr,"World")$
> World
> (%i5) stdout;
> (%o5) #<synonym stream to *TERMINAL-IO*>
> (%i6) stderr;
> (%o6) #<synonym stream to *TERMINAL-IO*>
