D web apps: cgi.d now supports scgi
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff some docs: http://arsdnet.net/web.d/cgi.html http://arsdnet.net/web.d/cgi.d.html The file cgi.d in there is my base library for web apps. Previously, it spoke regular CGI, FastCGI (with help from a C lib) and HTTP (with help from the netman.d and httpd.d files in that github). Now, in addition to those options, it also speaks SCGI - all by itself - and it can speak http without needing helper modules. The new embedded http server should work on all platforms too, not just linux like the old one, but I haven't tested it yet. This finishes out all the major web app interfaces that I'm aware of. To use them, you write your app with a GenericMain and always communicate through the Cgi object it passes you. === import arsd.cgi; void hello(Cgi cgi) { cgi.write("Hello, world! " ~ cgi.request("name") ~ "\n"); } mixin GenericMain!hello; === And then compile: dmd hello.d arsd/cgi.d # builds a CGI binary dmd hello.d arsd/cgi.d -version=fastcgi # FastCGI. needs libfcgi C lib dmd hello.d arsd/cgi.d -version=scgi # SCGI dmd hello.d arsd/cgi.d -version=embedded_httpd # built-in http server The API is the same with all four options. With cgi or fastcgi, you put the binary where your web server can run it. With scgi and embedded_httpd, you run the binary. It persists as an application server. On the command line, you can say use the option "--port 5000" for example to change the listening tcp port. The default for httpd right now is 8085. The default for scgi is 4000. Well, I don't have much else to say, but since it now does all four of the big interfaces easily, I thought I'd say something here. If you're interested in web programming with D, this will lay the foundation for you.

+1 for scgi support :) On Sunday, 25 March 2012 at 04:43:07 UTC, Adam D.

Re: D web apps: cgi.d now supports scgi
Thanks for doing this (and the other misc stuff) I wonder how can I generate unique, non predictable session ids.

In web.d, there's a Session class that generates them with std.random.uniform. I suspect this isn't the best possible, but it's worked pretty well so far. The session class also uses a file to store persistent string key/value data.

Re: D web apps: cgi.d now supports scgi
I can't compile web.d Notice: As of Phobos 2.055, std.date and std.dateparse have been deprecated. They will be removed in February 2012. Please use std.datetime instead. arsd\web.d(2671): Error: function std.date.dateFromTime is deprecated arsd\web.d(2672): Error: function std.date.yearFromTime is deprecated arsd\web.d(2673): Error: function std.date.monthFromTime is deprecated

Rock'n'roll!! Slightly off-topic, but what is your policy of derivative works Adam? So if I built something similar off your work, but gave you credit, and pushed any changes/bugfixes/improvements back to you, that would be ok? Basically, if I build my own libraries off yours, I assume that fine. Since I don't really want to repeat all the work you have done already. -- James Miller

On Sunday, 25 March 2012 at 20:12:16 UTC, dnewbie wrote: I can't compile web.d Oh yeah, Phobos loves removing perfectly good functionality. Just open the file and comment out that function. Make it simply: string date(string replacement, string[], in Element, string) { /* auto date = to!long(replacement); import std.date; auto day = dateFromTime(date); auto year = yearFromTime(date); auto month = monthNames[monthFromTime(date)]; replacement = format("%s %d, %d", month, day, year); */ return replacement; } and it will be fine. That function isn't really needed, it is just one of the template formatting options. Eventually, I'll port it to the monster that is std.datetime but I'm not in a big rush.

It is generally Boost license like Phobos (I put it at the bottom of the files since licenses annoy me) which is pretty permissive. and pushed any changes/bugfixes/improvements back to you, that would be ok? Yea. And if your new functions might be generally useful or mix right it, feel free to do a pull request for that too. It is a "misc stuff" repo :P

BTW I tried to keep Session simple, and there's some doc comments, but the basic usage is as simple as: // loads the session, or creates a new one if needed auto session = new Session(cgi); // it does NOT auto save, so you want to call // session.commit() when you're done. // scope(exit) makes that easy. scope(exit) session.commit(); bool checkLogin() { if(session.hasKey("user_id")) { // see if a key is set // the user is logged in string uid = session.user_id; // can get data via opDispatch return true; } return false; } void logout() { session.invalidate(); // clears and deletes the session } void login() { session.invalidate(); // kill the guest session session.user_id = uid; // save the user id in the session via opDispatch } If you use web.d's FancyMain, it creates a session for you, so your ApiProvider class already has a session member you can tap right into. import web.d; class MySite : ApiProvider { void something () { session.cool = "something"; // works } } mixin FancyMain!MySite;

The session class also uses a file to store persistent string key/value data. While using std.random is probably good enough for most sites, it's definitely worth keeping in mind that these session IDs are far from non-predictable. Generally, a secure random number generator is used instead, but Phobos lacks something like this.

I'd recommend moving those two html pages to github's wiki, or some other wiki. If people start using your library they can contribute with explanations, example usages, etc. I also see many empty or short sections in those documents, which again I think is asking for a wiki. I'm also not sure about the format you provide for getting the code: many unrelated modules all in a single directory. If I want to start developing web apps using your framework I need to clone that repo, think which files to import, etc. If all the related web stuff were in a separate repository, I could just clone it, import an "all" file and that's it. (well, the last point isn't really your fault, something like Jacob Carlborg's Orbit is really needed to make D code universally accessible and searchable)

If people start using your library they can contribute with explanations, example usages, etc. Yeah, I started that for the dom.d but haven't gotten around to much yet. I also see many empty or short sections in those documents, which again I think is asking for a wiki. or for me to finally finish writing it :) I'm also not sure about the format you provide for getting the code: many unrelated modules all in a single directory. They aren't really unrelated; most of them worth together to some extent. If you grab web.d for instance, you also need to grab cgi.d, dom.d, characterencodings.d, sha.d, html.d, and color.d. If you are doing a database site, you can add database.d and mysql.d (or postgres.d or sqlite.d) to the list. curl.d and csv.d are nice for working with external sources of data. rtud.d depends on cgi.d for pushing real time updates. So, all of it really does go together, but you don't necessarily need all of it. dom.d and characterencodings.d can be used independently. cgi.d has no external dependencies. etc. They are independent, but complementary. (well, the last point isn't really your fault, something like Jacob Carlborg's Orbit is really needed to make D code universally accessible and searchable) I could add my build.d up there too... which offers auto downloading and module adding, but it is kinda slow (it runs dmd twice).

How slow is it comparing it to a developer doing it manually? :-)
