Thanks, got that working with ease. The operation of dub has gotten 
quite a bit smoother, props to Sönke!

One thing that I found surprising is the chatter that seems impossible 
to mute. Here's a session:

$ dub run dscanner -- --sloc ../phobos/std/traits.d
Building package dscanner in /Users/andrei/.dub/packages/dscanner-0.4.0/
Target libdparse 0.7.0 is up to date. Use --force to rebuild.
Target emsi_containers 0.5.3 is up to date. Use --force to rebuild.
Target dsymbol 0.2.0 is up to date. Use --force to rebuild.
Target inifiled 0.0.6 is up to date. Use --force to rebuild.
Target dscanner 0.4.0 is up to date. Use --force to rebuild.
Running ../../.dub/packages/dscanner-0.4.0/dscanner --sloc 
../phobos/std/traits.d
../phobos/std/traits.d:	3747
total:	3747

I might be missing something, so bear with me. My current understanding is:

* The usual way to run stuff gotten via dub is with "dub run", so that 
people don't need to deal with version directories and complex paths 
such as ~/.dub/packages/dscanner-0.4.0/dscanner.

* There is no easy way to get rid of the chatteroo prefacing the actual 
output from the application. One possibility I imagine is a rather 
gnarly sed script that prints nothing until it detects '^Running ', and 
then starts printing everything.

* There is even no --quiet option 
(https://code.dlang.org/docs/commandline#run) with run that instructs 
dub to not inform about things being up to date.

Are these correct? In that case, dub runs afoul of the Rule of Silence: 
the command "dub run xyz" should only output whatever xyz outputs if dub 
takes no actual additional build steps. By the RoS, there might be a 
--verbose flag with dmd run that prints the above.

What am I missing?


Thanks,

Andrei
