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;

if (response !is null)
{

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

drenoob <dlang none.org> Apologies for the terribly misformated and obtrusive error messages of the 2nd part. I'll try my best to' earn and get used to this forums formatting. Again, I'm sorry.

Thank youI'm not sure about support of "on progress" in other libraries, but simple examples can be found in this repo: https://github.com/cyrusmsk/d_http_client_benchmark So some comments: 1) Arsd solution - now can have some difficulties with dub integration. But can be suggested solution if you are using other arsd libraries and OpenD compiler 2) Vibe solution - should be solid, but a bit heavy (probably will install some other dependencies). Can be suggested if you are planning to use Vibe.D framework 3) Requests - nice library, currently not maintained very actively, but should work. The main issue could be with the usage on Windows. So I would recommend to try this solution, if you are not on Windows.

But then: *is* there a place where one can find stable/mature/maintained and/or trustworthy D libs? OK, in my case falling for a, let me call it questionable, lib was desastrous because *of course* it makes a language look not exactly great when right at the get-go one walks into a "trap". But I guess I'm not the only one who, to a major degree came to D because I wanted a *mature* tool (and "universe"), and probably quite many would value a place where one hadn't to play lottery but could find reasonably reliable libs. Btw, are there any more or less agreed upon standards re (lib) docu here in the D-lang community? I'm asking because that (largely non existing lib docu) was one of the major reasons I gave up on another language with plenty "funny" experiments but precious little one could actually work with wrt docu (and rely upon). Be that as it may, I thank you.So, I shouldn't trust libs that are in the offical dub repo? Strange and sad..The dub registry is no different than nuget's or npm's.

Be that as it may, I thank you.I'm not sure what do you mean.. Did you check the official web-site? There are a lot of docs regarding the language and standard library (name Phobos): https://dlang.org/spec/spec.html https://dlang.org/phobos/index.html Regarding docs for 3rd party libs - it depends on the author of the lib - if provide the documentation. Usually they are putting some description into github or separate page. You can search them here: https://code.dlang.org There is no "recommended and maintained list of packages". DLF doesn't want to do that.. Mostly because D doesn't have any resources.. It is trying to do the best with almost 0 resources. So I would recommend just to ask here in "Learn" place or come to Discord and ask there which library you want. Search functionality on dub is working.. but working pretty badly and has several issues But Discord people know **all packages** that D's ecosystem has - so they will help you with any request :)

C/C++/Rust do not have it either for a reason - it would expand the standard library too much (assuming it covers everything). Whenever I had to do http requests I used the excellent dlang-requests library ( https://github.com/ikod/dlang-requests ). It was a natural choice as I do Python programming on a daily basis... dlang-requests is in my top 10 list of all D packages just like Python `requests` package is in my top 10 Python packages. Highly recommended.
