Hi Gavin,
Thanks for reaching out!
My primary concern is that `dc -e' returns to its previous auto-exit behavi=
or. Any of the options you described would achieve that, and would be fine w=
ith me.
Thanks again,
Ravi (rpokala@)=20

Subject: bc and dc -e/-f and Copyright
Hello,
My name is Gavin Howard, and I am the developer and maintainer of the
new bc and dc implementation in -CURRENT. Stefan E=C3=9Fer brought a
discussion about my bc to my attention, and I would like to solve the
problems.
First, I will add some way to remove the printing of the copyright
header at compile time, and FreeBSD should be able to take advantage
of it as soon as I put out a new release, which should be within days
after this discussion is settled.
Second, there seems to be those who are unhappy with my decision to
make bc and dc not exit when using the -e and -f options. While the
behavior of my bc is what I personally need, I have a few options to
change it back to what is expected:
1. I could make it a compile-time selection. I don't like this option,
to be honest.
2. I could restore the expected behavior of -e and -f and change the
environment variable to BC_EXPR_NO_EXIT (DC_EXPR_NO_EXIT) and reverse
the logic. I could do this one, but Stefan mentioned to me that he
would prefer less environment variables be used. I agree.
3. I could restore the expected behavior of -e and -f and add -E and
-F options that do the same thing but do not exit. I think I like this
option the best. I am willing to change -E and -F to something else if
that would be better.
When I presented these options to Stefan, he suggested that I ask you
all for your opinions. I am also willing to consider other options
that you might think of.
Thank you for your time.
Gavin Howard
