Are there any FOSS tools for doing dependency analysis of (e.g.) all the

regenerated?
This presumably would depend mostly on the import statements (including
import of any file to be used in string construction, as in 'auto
my_string = import("my_file");').
dmd itself has two related switches:
* -deps prints out imports and such.
* -v prints out the same information in different format, and also a lot
more other stuff, including which dmd binary is being used and the
config file.
rdmd uses -v to figure out the dependencies of the root module. Here's
how it parses the output:

I'm not aware of a standalone tool that does something like this. If you
want to write one, you could do like rdmd and use `dmd -deps`/`dmd -v`,
or you could use a standalone D parser like libdparse.

(I'm using gdc, and building with gnumake.)
I'm not sure how similar or different gdc is to dmd with regards to the
-deps/-v switches. A quick test suggests that gdc has a --deps switch
that behaves like dmd's -deps. It seems to be undocumented. The output
of gdc's -v does apparently not include the imports, though.
