I first started with a Windows message box program and installing an
IDE. I'm now using the VisualD plug-in with the Visual Studio 10 Shell,
after battling a bit with installation of service pack 1 for Visual
Studio. VisualD works, sort of, except the devs forgot that the resource
compiler needs an INCLUDE variable so that it finds <windows.h>, so,
silly as it is, the VisualD plugin can't be used directly as-is to
create a modern look and feel Windows program. I solved it by running
Visual Studio from the command line.
Anyway, I haven't yet started delving into the language documentation or
any tutorials, just used gut-feeling, so I'd appreciate discussion of
how to make this my first D console program less non-idiomatic <g>:
<code>
import std.stdio;
import std.ascii;
import std.string; // chop
//import core.sys.windows.unicode_based_api; <-- DOES NOT WORK.
char lastCh( string s )
{
return (s.length == 0? '\0' : s[s.length - 1]);
}
void main()
{
char[] buf;
writeln( "module core.sys.windows.unicode_api;" );
writeln( "import core.sys.windows.windows;" );
while( stdin.readln( buf ) )
{
string identifier;
bool inIdentifier = false;
foreach( char c; buf )
{
if( isAlpha( c ) )
{
if( !inIdentifier ) { identifier = ""; }
identifier ~= c;
inIdentifier = true;
}
else if( c == '_' || isDigit( c ) )
{
if( inIdentifier )
{
identifier ~= c;
}
}
else
{
inIdentifier = false;
if( isWhite( c ) )
{
// Ignore.
}
else
{
if( c == '(' && lastCh( identifier ) == 'W' )
{
immutable string name = chop( identifier );
// removes last char
writeln( "alias ", identifier, " ", name, ";" );
}
identifier = "";
}
}
}
}
}
</code>
The problem is, I can't manage to build the generated module.
The compiler is protesting something about the module being in a source
code file that it can't read.
E.g. with "import unicode_based_api;" it exclaims,
<eror>
Error 1 Error: module unicode_based_api is in file 'unicode_based_api.d'
which cannot be read d:\winfolders\alf\my documents\visual studio

What is "unicode_based_api" file? I don't see it in core.sys.windows:

I don't see it in core.sys.windows: http://github.com/D-Programming-Language/druntime/tree/master/ rc/core/sys/windowsOh, I guess I understand what you're trying to do. IIRC, druntime source files get compiled into phobos.lib, so to make add-on for it you should rebuild both druntime and phobos.

And not to be artificially restrained, it's not likely that your question regarding import search paths will fundamentally affect the D module design, is it? :P Anyway, as far as the compilation model goes, for everything search path and linker-related, a useful first-order approximation is just to think of it as C++. Each import search path (from dmd.conf/sc.ini or the -I command line switches, plus the working directory) is treated as possible root, and similar to »#include <foo/bar.h>«, »import foo.bar;« looks for a foo/bar.d file in any of the import directories. So, if you really want to extend druntime's core package (which you normally don't, unless you plan on submitting your additions back upstream), you would put your generated unicode_api.d in a core/sys/windows directory under one of the import search paths.

As a newbie one tries things and asks about things that a person more accustomed to The Usual Ways(TM) just discounts immediately without further reflection -- missing out on the opportunities... For example, I hope that some good nice person will add the enclosed module to the standard library, so that people accustomed to clean Windows API function names in C++, can have the same in D.Anyway, as far as the compilation model goes, for everything search path and linker-related, a useful first-order approximation is just to think of it as C++. Each import search path (from dmd.conf/sc.ini or the -I command line switches, plus the working directory) is treated as possible root, and similar to »#include <foo/bar.h>«, »import foo.bar;« looks for a foo/bar.d file in any of the import directories.That's what I did. I've now additionally added the file to the Visual Studio project, and that worked.So, if you really want to extend druntime's core package (which you normally don't, unless you plan on submitting your additions back upstream), you would put your generated unicode_api.d in a core/sys/windows directory under one of the import search paths.OK. So, since I don't know anything about how to "submit additions back upstream", I just enclose it here. Could the right "upstream" person please grab hold of this and Do What Needs To Be Done(TM)? I'm assuming that the need for this module or a module like this, is obvious with hindsight (given its existence now). Also, that the ease of accessing the OS API on the most common platform, impacts on the usage share of D. I'll be happy to explain further if desired. Cheers, hth., & TIA., - Alf

I do not yet have the foggiest idea about how D building works, except compiling individual source files. I just thought it doesn't matter which program it's used from then, so I put the `import` in the generating program. Cheers & - Alf

I've never liked that practice - preferring to call the desired function explicitly (whether that is dirty or clean is not of much import, it is what it is as Microsoft saw fit to name it).
