Re: [fricas-devel] output file type....
The question was very clear and self explanatoryI asked how to output a string into a file without the leading "1." and without the double quotes.

Re: [fricas-devel] output file type....
I was basically going according to book.pdf. I'm not aware if there are
better ways to do file I/O in fricas. I have a large script that does many
algebraic calculations and then outputs the result to a file. The output
consists of algebraic types as well as strings of text and I don't know how
to output them all together nicely! Also, I'm not familiar with SPAD.

Re: [fricas-devel] output file type....
Why do you think it is wrong?
https://github.com/fricas/fricas/blob/master/src/algebra/files.spad#L132
Honestly, I could not judge this. The docstring for write!
http://fricas.github.io/api/FileCategory.html#l46696c6543617465676f7279-777269746521
is not very precise.
The only thing you can say is that it is not what you expected.
Just to make things clear.
OK, but that doesn't help you. I was anyway wondering why you would be
satisfied with output that looks pretty LISP like. Is this really what
you want?
Don't just work on "somehow getting some output". Try to specify exactly
what you want and how you want it. Maybe your input data comes in a
certain format from somewhere and you want you output in a certain
format for further use. So what is it?
Maybe putting together a few lines of FriCAS code and a little shell
script may better serve your purpose. However, to be able to help you,
you must be much clearer.

PS:
I actually don't care about what write! outputs. I never had such a need
to use it. As I said before, the fricas output of
https://fricas.github.io/book.pdf was produced automatically. And since
I programmed it I know that there is not write! command in the process.

[fricas-devel] output file type....
I have an output file opened of type union (for mixed types):
f : File Union(List Integer, String) := open("test.out", "output")
write!(f, [1,2,3,4,5,6,7,8])
write!(f, "0123456789")
close!(f)
Here's the content of test.out:
(0 1 2 3 4 5 6 7 8)
(1 . "0123456789")
The 2nd line containing the string doesn't look right. How do I print the
string itself (without the prefix 1.) and without the double-quotes?
