rant?!? maybe you got the message wrong. It was about the purpose of
configuration file and the target users for it.
your message was very emotional. you defined the target users in your
message. i have not seen that discussed or agreed earlier.
well, somehow is what I see everywhere I deal with. Barely found
programmers to manage operational systems, being it web servers, mail
servers, voip servers, a.s.o.
my claim is
that current config language very much resembles a programming
language.
That is quite some problem imo, so instead of make it more complex, I
will try to reduce it complexity and make it more use friendly.
please tell a non-programmer, how he/she can easily
test if a var holds integer 0 value?
I don't see the relation of this question with auto-conversion debate
and type checking.
it has, because if target is a non-programmer, then it should be very
easy to do. that was the problem where this whole discussion started.
I don't think the target is to have a generic programming language,
where the admin doesn't know what comes and from where, so it has to do
a lot of checks to find out.
The variable is set somehow, either taken from database of directly in
config. Who does the logic know what comes there. If I do $var(x) = 1; I
know it is integer. I haven't found a need to test the type of variable
so far, but, if someone has an there is no function for finding out the
type of value, it can be written.
here is a real world example for you: make a single htable query and
find out, if the resulting value is string "0" or if there was no result
at all. for performance reasons i don't accept answer where the query
is done two times.
Yet the performance is another topic. How much penalty a htable query
could bring? If you look into the c code of many functions there are lot
of too many safety checks that can be removed. I think we can do more
processing than the pipe can handle.
So, really, this is not anything like flame war, just making sure we
don't rewrite c interpreter, because nobody is going to use it.
you are exaggerating. there is big difference between type safety and c
language programming.
This is one step in that direction rather than opposite. So my concern
was not to end up rewriting it.
Cheers,
Daniel
