Compiler information as part of code.
*** #ClassName : gives you the name of the current class
Often I setup loggers and stuff, and always do something like:
class blah
static Logger Log = new Logger( "blah");
what I'd like to do is have a context aware statement that got built at compile time (much like the old C++ __line and stuff) -
eg: static Logger Log = new Logger( #className )
We've talked about this, but haven't been able to come up with a clean way of doing it. We do understand the value.
*** #member : gives you the name of the member you are in
same as above, it'd be nice to be able to do things like put stuff about what procedure I'm in:
eg:
public void Blah()
{
Log( #currentProcedure + ": first line");
}
ibid.
*** "meta" parameter definition
This is a little off the wall, but it'd be easy to do, and really cool - have a tag called "meta" which you can put on a parameter - which will actually compile to send information about the actual parameter
for instance, at the moment I have a thing called EnsureNotMissing( string, object), which just does a "if null throw exception (" parameter " + name + " is missing )
that means at the moment I have to say
EnsureNotMissing( "myParam", MyParam );
I would like to build
public void EnsureNotMissing( object MyParam, meta(MyParam) objectData )
{
if (myParam ==null)
throw new exception( (objectData as ParameterInfo).name + " is null");
}
so I can just say
EnsureNotMissing( MyParam ); - and the compiler will actually throw in the other stuff, like the name
This would be a nice feature. It's something we've touched on obliquely when we talked about __FILE__ and __LINE__
