Hello,
Finally re-discovering D again I wanted to try a small side project which largely is but an http[s] client. So, i tried first std.net.curl - and it failed. Then I tried the hunt lib - and it failed again.Note that in both cases I basically tried an example those libs provided.
Here's the curl code, in desperation slimmed down to an almost verbatim copy of their example:
------------ std.net.curl code --------------
1|import std.net.curl, std.stdio;
3|auto totLen = 0; // mine
4|auto http = HTTP("https://some.url");
5|http.onReceive = (ubyte[] data)
6|{
7| /+ drop +/ totLen += data.length; // mine
8| return data.length;
9|};
10|http.onProgress = (size_t dltotal, size_t dlnow,
11| size_t ultotal, size_t ulnow)
12|{
13| writeln("Progress ", dltotal, ", ", dlnow, ", ", ultotal, ", ", ulnow);
14| return 0;
15|};
16|http.perform();
// ---- End of code ---
the two lines I added or changed are commented '// mine''
the 'xx|' at the beginning of each line is the line number
This results in
source/app.d(5,16): Error: variable name expected after type http.onReceive, not =
http.onReceive = (ubyte[] data)
^
source/app.d(5,16): Error: declaration expected, not =
http.onReceive = (ubyte[] data)

return data.length;

};

======================= hunt lib ==============================
import hunt.http;
import std.stdio;
enum tgtUrl = "https://some.url/";
void main()
{
auto client = new HttpClient();
auto request = new RequestBuilder().url(tgtUrl).build();
auto response = client.newCall(request).execute();
if (response !is null)
{
writeln("status code: %d", response.getStatus());
writeln(response.getBody().asString());
}
}
// ---- End of code ---
results in

Sorry, dear colleagues, while I still presume D be a stable and really decent language and very much welcome the fact that at least many libraries are not version 0.0.[whatever small number] (so basically alpha or beta at best), I hope you can understand that this first experience isn't exactly strengthening my hopes for and trust in the D universe ...
Or did I make a total noob mistake? If so (or even if not) please kindly let me know how to get some decent http client working.
Btw. DMD and dub have been freshly installed and should be current.
Thank you
