Yes, though binary CGI support is also very common.
Agreed. I've made several CGI apps, mostly with powtils. Though certainly
possible, not good for interactive Web Apps using Ajax techniques that need
connection pooling, rich session storage, etc.
The problem I think has also been lack of a central and openly available
(open source?) framework to rally around for web development in pascal in
order to foster an eco-system like we see with traditional 3rd party
components and libraries.
What framework do you need to build web apps using pascal? Web apps is just
about read browser request and reply to it. A custom simple communication
class (to encapsulate the request-reply process) should be sufficient.
A framework like fpWeb or something similar some years ago that takes care of
all the boiler plate code necessary to produce web content would have been nice.
I've been playing with javascript (particularly the dojo framework) a lot
lately and its really not that bad once you get used to the loosey goosey
weak typing and creating function objects on the fly as parameters to
functions, etc.
Making web pages using pascal is a bit tedious work due to HTML and CSS
thingy. But for web apps, especially RIA, with the help of good JS UI
framework, you just simply need to learn JS and a bit of JSON. For people who
had been working for years with pascal and need to move to web app
development, code reuse is a HUGE advantage. Code reuse isn't just about
copy-paste the code, but also the testability and stability, which you need
to do it again from start if you rewritten in another language.
Right. All that code that we've written, collected, modified and maintained and
proven over the years is right there, at our beck and call to use whenever we
want with the added bonus of not having to relearn new libraries or frameworks
to do things. LazReport is a good example I think.
Even without legacy code at our disposal, pascal still has compelling reasons to
be used in web applications.
