I finally decided to bite the bullet, and to dump the idea of
extpascal and
the likes for the moment. All these conversion tools have the same
problems:
- Always behind the latest versions of the corresponding JS toolkits.
- They only do a subset of what the JS toolkits support natively.
Yes! It happens to ExtPascal each time ExtJS releases a new version.
- For anything reasonably advanced, you need to write JavaScript
anyway.
It's sad but true. While I believe it can be avoided for any common
purposes, but in some advance optimization it just can't be. Just like
the way we're using assembler in pascal. But it should be 1-5 percents
of all cases.
I have the first server-side things ready, namely: the server-side
interface to ExtJS's data API. It's a breeze in FPC, and lightning
fast.
It would be better if the server side interface is plain and
independent to any JS framework API. The interface result then could
be "translated" to any client side API, or SOAP, or WST, or whatever
is required format by the client side framework using some kind of API
dictionary or something similar.
At a later stage the following will be added:
- Write the client in Pascal, but transformed to JS using a code
converter.
(as Morfik or GWT does)
This is my dream. It would be better if the converter is able to
provide library binding to any JS framework out there, at least the
popular ones i.e. ExtJS, jQueryUI, qooxdoo, etc. So we don't need to
code on our own JS UI widgets. This is one of major flaw of Morfik.
Though I knew what I want, I have very limited time and skill to
develop it by myself while the deadline for the demanded application
can't be delayed. That's why I have to satisfy with any ready to use
tools available for pascal now, which is ExtPascal. Now come the new
one: fcl-web.
I've contracted Mattias Gaertner to do the first step for the code
converter. Sources will be donated to and released with FPC.
I also wrote a JavaScript parser, which will be introduced in FPC's
SVN
shortly.
Many had tried it already i.e. Powtils, ExtPascal, but the development
stucks somewhere. I'm looking forward to test it! Thank you for the
effort.
