The log aliases use names that are too common. I think log.info is a
better symbol for logging than just 'info', which could be a symbol in
a myriad of places. Given that D's symbol lookup rules allow shadowing
of global symbols, this does not work out very well.
Originally, the code used log!info and so on, but it was changed to the
current design right after review begin, the rationale being that you
could always use »import log = std.log« if you want the extra namespace.
That doesn't help. Software isn't static.
import std.log;
import other; // defines B
class A : B
{
void foo()
{
info("some info message"); // error! int isn't a function!
}
}
other.d:
class B
{
int info; // added later
}
Like others have stated, I think vlog is a) confusing, and b)
unnecessary. Even reading the docs, I can't understand what it's used
for, and why it has such different syntax than the normal logging stuff.
I think this been modelled after glog's verbose logging support [1],
just like much of the rest of the design (by the way, I think a note
about this should added somewhere in the module docs). Does the feature
as described in the glog docs make sense to you?
It's good to know the root of where this comes from. The docs in glog do
make more sense than the vlog docs.
This may be a doc issue. I'll have to think about it some more.
