I dont' want to battle among languages, but I see that in Golang 
there is a beatiful solution to display HelloWorld program in web

convinced there is a D equivalent?

Can someone say what's its aspect?

Thanks in advance,

It all depends on the library. If you use my code https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff It looks like this: == import arsd.cgi; void hello(Cgi cgi) { cgi.write("Hello, world!"); } mixin GenericMain!hello; == You can build that as a cgi app to drop into any web server, a FastCGI app to use a longer running process on almost any webserver, or a HTTP server, standalone. Get cgi.d from my github then Fast CGI C library from the internet (search for libfcgi) or get netman.d and httpd.d and standalone, only works on linux

There's no built in webserver class, and it's not something that should be in the standard library in the first place.

Why is this a pain, I don't see the problem. You've got an awesome solution, just because it's not in Phobos? I don't understand why people hate to install (it's not even installing just downloading) libs.

I think phobos should include a simple http server for testing purposes.

You can just comment out the code there (afaik it is only a custom formatting routine), or compile with the -d flag.

You're probably thinking of the std.date use in web.d. This one though is just older stuff that you don't need with the new cgi.d. BTW the Phobos team deciding to break std.date is still though if -property becomes the default, we'll have a new king.

Use the newer standalone code: http://forum.dlang.org/thread/cifekffsnaimfsvuxlrw forum.dlang.org?page=2#post-pfojnbnvhuahnyviekut:40forum.dlang.org don't need netman.d anymore. Just use: gdmd server.d cgi.d -version=embedded_httpd to compile it.

Oh my, indexOf was deprecated? News to me.

i think you've got only pure stocket library around std.socket or something like that - maybe you find an implementation of an web-server in the tango library
 Can someone say what's its aspect?
???
