This is an enhancement request.

I would like it if dmd would print a line on the standard output when it
encounters an entry point function ("main" or "WinMain"). Optionally, the
module name where it was found should be printed as well.

This will allow build tools, like rdmd, to react intelligently based on what is
specified on the command-line. If there is no entry point defined, the build
tool may select to skip linking, or build a library, instead of attempting to
link an executable (which will likely fail due to lack of an entry point).

In my case, it would allow creating a file manager association with .d files,
such that executing the association on a main program file would compile and
link the program, and executing the association on a component module would
merely check the code for compilation errors.

From what I can tell there's 3 types of main functions:

main
WinMain
DllMain

So how would you like the output to be? It could be:

binary    E:\dmd-git\dmd2\windows\bin\dmd.exe
version   v2.063
config    E:\dmd-git\dmd2\windows\bin\sc.ini
parse     Fix9680
importall test
import    object   
(E:\dmd-git\dmd2\windows\bin\..\..\src\druntime\import\object.di)
import    foo.bar    (foo\bar.d)
semantic  test
main      foo\bar.d  <-
winmain   foo\bar.d  <-
dllmain   foo\bar.d  <-
semantic2 test
semantic3 test
code      test

Either one of the 3 marked with the arrow would show up, or perhaps you want
some other way of marking them?

I can have a pull ready soon.

Oh, good point about printing the entry point kind (winmain/dllmain)! Then the
build tool could also do the right thing and build a DLL, or pass
"/SUBSYSTEM:WINDOWS" to the linker.

How about this format:

entry    main    foo\bar.d

"entry" is constant, "main" is the entry point kind (main/winmain/dllmain), and
the third field is the path name. This leaves room for detecting other kinds of
entry points if that's something that might happen (extern(C) main?)
