           Summary: compiler shall print dependencies and pragma(lib)
           Product: D
           Version: 0.178
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: benoit tionex.de


Let the compiler have a new commandline switch:

-bldinfo
-bldinfo=filename
Prints the bldinfo either to the console or into the given file. The bldinfo
contains informations about found dependencies and pragma(lib) statements. 

Every bldinfo line has the format:
"bldinfo <recordtype>: <info>"

Every active import from a module will be printed like this:
"bldinfo import: %s(\"%s\") => %s(\"%s\")", moduleFQN, moduleFileName,
importedModuleFQN, importedModuleFileName

Every active pragma(lib) is printed like this:
"bldinfo pragma-lib: %s(\"%s\") => \"%s\"", moduleFQN, moduleFileName,
stringFromPragma

"Active" here means, the statement is relevant for compilation. It is not
deactivated through version/debug/static-if conditions. 

Filenames are printed as absolute paths.
Filenames and strings are escaped like the D string literals and they are
double  quoted.

If printed to the console, the bldinfo is printed in between the other
messages.
The bldinfo is printed without any special order.
The bldinfo is printed for all modules given on the command line.
The bldinfo is also printed recursively for all modules that are imported.

I believe this is mostly implemented in the -deps flag. Is anything left to do?

You still can't get the libs requested by pragma(lib ...).

dmd -v will print the libs, but that's not comfortable enough.

I would like too see string imports to be shown in the dependencies:

c:\>type test.d
int ver=mixin(import("Version"));

c:\>type version
42

c:\>dmd -c -J. -deps=deps test.d

c:\>type deps
test (test.d) : public : object (m:\\s\\d\\phobos\\druntime\\import\\object.di)

This should show "version", too.

Libraries "imported" by pragma(lib) to be shown would be nice, but this is not
complete for a building tool, anyway, because pre-built libraries might force
the inclusion of more libraries. I'd like the linker to supply a list of
searched libraries.

I figure dmd doesn't report these string imports because it would require full
semantic analysis of the code. Which would be much slower, making the -deps
mode less useful.

Maybe the compiler should provide an "-a" flag, which automatically builds all
imported modules? Incremental building is broken anyway (at least due to bug
3274, other reasons include CTFE, which subverts module dependencies, and some
types of out-of-declaration bugs [forward refs]).

Then dmd would need to run semantically analysis only once to build a program.
To facilitate building relatively independent packages as libraries, another
flag could be added to dmd to exclude certain package paths using glob
patterns.

Sorry for the previous comment, I think I accidentally hit soem key
combination, that made the browser to submit the form.

-deps does not enable a different mode, it just tells dmd to output any file
imported to the given dependency file during the normal compilation process.

There is no need for an extra compilation step, just use the info in the
dependency file from the last compile to figure out if an update is necessary.
