Re: [fpc-pascal] TCgiApplication in cgiapp unit - mostly deprecated
I am working on a project now for RIA similar in concept to ExtPascal, but abstracting out the UI framework with most of the logic executing on the server so that I can plug in different UI's without touching my model/controller. That is what I looking for! That is what I looking for! I do not want to use ExtPascal because it depends on ExtJS and their documents (to generate the Pascal code). I wish I could choose the JavaScript framework. from the documentation of ExtPascal: file:///C:/ExtPascal/help/Overview.html (bottom part) the Parser can be adapted to read the documentation of another JavaScript framework, Dojo for example.

Yes, he can, but the code generated contains the same classes and methods of ExtJS. So, if we adapt ExtPascal for other JS frameworks, the code would be very different... in other words, the framework Pascal do not be homogeneous for many JS frameworks.

Can't get simpler than this:
-
program cgitest;
{$mode objfpc}{$H+}
uses
Classes;
begin
writeln('Content-Type:text/html',#10#13);
writeln('html');
writeln('headtitleFPC Test/title/head');
writeln('bodyHello World/body');
writeln('/html');
end.

Output is shown in the attached screenshot. Obviously you need a webserver
to correctly view the results. Simply install Apache and enable CGI support
(if not enabled by default).
As you can see from the sample application, CGI apps are simply glorified
console applications.

All debug output is cached output (except for console) and thread safe - works perfectly under our test systems (Windows and Linux).

Here is a Web Server programmed entirely in Freepascal: http://ip.klimaregelung.de/ip.php?action=connectbenutzercode=Stratmann No Apache or PHP or something else. Because it is a small embedded computer at home only 20 connections at a time are possible. But it would be possible to expand with more powerful computers. I am HAPPY with Freepascal!

how do I build a minimal 'hello world' CGI application under Free Pascal ? Where do I find 'instructions for dummies' ?

I haven't used FastCGI yet, but there seems to be an implementation included with FPC. fpc_src/packages/fastcgi/* I want codify a web app and I think use FreePascal. You recommend that? Free Pascal is a very good choice for CGI web applications. You have the full RTL and FCL at your disposal. I even use a OPF (Object Persistent Framework) with our CGI apps. Best of all, I didn't have to learn a new language like PHP, Java, Python etc. :-) -- Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

There is no documentation for this unit, so I do not know much about it. If all those methods are marked deprecated, what is replacing them? The whole cgiapp unit is deprecated, you should use the TCGIApplication from fpCGI. Lazarus has a package to create web applications with the fcl-web units.
