digitalmars.D.learn - Static if on release build

I can't find any documentation regarding conditional compilation

I have read the page regarding the topicon dlang.org but adding 
the snippet below makes no difference when compiling with dub -b 
release
{
version(full) {
  //do something
} else {
//do something else
}

How can I produce a release version with different parameters 
from debug using dub and static if's?

Take a look at this:

Well yeah... full doesn't exist[0].

If debug is turned on:

debug {

} else {

}

That else isn't for 'release'. Release turns on optimizations in the 
compiler and disables a few other things like asserts.

If you want to specify a version at the command line use 
``-version=MyVersion``. For a debug identifier use ``--debug=MyDebug`` 
and yes, debug conditions can have identifiers like versions require.

For dub you can specify it via ``versions`` and ``debugVersions``.

The most close compile condition is

version(assert)
{
     // build for testing
}
else
{
     // build for release
}

see https://dlang.org/spec/version.html#predefined-versions:

"assert	Checks are being emitted for AssertExpressions"

And at the same time

https://dlang.org/dmd-linux.html#switch-release

"compile release version, which means not emitting run-time 
checks for contracts and asserts. Array bounds checking is not 
done for system and trusted functions, and assertion failures are 
undefined behaviour."

Note thatwith D compilers -debug and -release are not opposed to 
each other. A program can have both flags, or none.
