Re: D simple web server
Hi, I added websocket support to the server. This is the link to the git repo: https://github.com/gedaiu/DSWS Thanks, Bogdan
Re: D simple web server
Thanks for reply,
@Adam D. Ruppe I ignored your collection of tools but is not very
good documented...
@Rémy Mouëza When I started my project, I wanted to use mongoose
but there where no bindings for D at that time, so I decided to
use a simpler web server, libmicrohttpd, but it was not the best
solution because my server where crashing all the time, so I
decided to create one from scratch in D.
I made an update to the code and I added the option to initialize
the terver using delegates.
Thanks,
Bogdan

Your code seems rather nice.
That said, here are some remarks of a purely stylistic nature
:-) :
- You can use foreach instead of for to simplify your loop
statements over arrays and other collections:
auto array = [1, 2, 3];
foreach (item; array) {
writeln (item);
}
foreach can also support indexed iteration of your items:
auto array = [a, b, c];
foreach (index, item; array) {
writefln (%d: %s, index, item);
}
and if you just want to iterate a certain amount of time, you
can use ranges:
foreach (index; 1..100) {
writeln (index);
}
- You don't have to put each class in a different file: you
still can do if you prefer it that way.
- I tend to prefer to have class members of same visibility
grouped together under a public:, protected: or private:
block, either using the colon or the braces instead of always
specifying the visibility - this kind of help me better
understand what will be useful when using the class.
- Associative arrays can be initialized with literals, so
instead of having lots of:
status_message[100] = Continue;
status_message[101] = ...
...
status_message[505] = HTTP Version not supported;
you can use:
status_message = [
100: Continue,
101: ...
505: HTTP Version not supported
];
which I find more concise.
- You can also use unified function calls:
instead of: to!string(port)
you can do: port.to!string
the latter having a more English feel when reading.
Again, these are purely stylistic considerations, D's
flexibility allows you to choose from many styles.
On a design standpoint, I would have preferred a delegate for
the processRequest() method instead of requiring the users to
derive from the WebServer class - on second thought, that may
too be a stylistic issue :-) .
Also related: I have started to write some high level bindings
to the Mongoose embedded webserver library, written in C (using
Jacob Carlsberg's dstep for the low level bindings). The source
code is available here:
https://github.com/remy-j-a-moueza/mongooseD .
You may find some stuff to reuse or get inspiration from for
your server.
Adam Ruppe also has a lot of interesting tools beyond the basic
web serving that you may get interested in
(https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff).

My cgi.d has one too:

===
void hello(Cgi cgi) { cgi.write(hello); }
mixin GenericMain!hello;

dmd test.d cgi.d -version=embedded_httpd
Then run test and it listens on port 8085 by default, and you can
change that with a command line argument --port 3000 for example.
