Hi,

I wonder if there's standardized way to gather which files are imported by a source file. I know I can run "dmd -v" and look for lines start with "import", but I don't know if this is the best way to do it.

You can use the "-deps" flag.

-deps is even noisier than just -v...

This is what the -deps flag is intended for:

 -deps          print module dependencies (imports/file/version/debug/lib)

There's also the -deps=<filename> flag, kind of similar:

-deps=filename write module dependencies to filename (only imports)

It's pretty noisy alright, but it's also pretty easy to read...

It also shows just how coupled phobos is.
I'm importing one single function (std.stdio.writefln), and all the dependencies are imported:

Also the output format seems to change between versions (or between compilers, I don't know).

Because dmd 2.071 prefix lines with "depsImport", while ldc (based on dmd 2.070.2) doesn't.

The -deps and -deps=<filename> will give you different output. See "dmd --help".
