Right now it's completely up to the application programmer to do the two parts of the application and to mange the communication between them. But it would be a viable task for Lazarus (ow whomever) to provide a "standard" Methodology / Library / IDE integration to allow for splitting a "normal" application in such parts. I understand that Microsoft (quite promising but finally rather unsuccessfully) had this in mind with Silverlight (C# running seamlessly in a browser). -Michael ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel

TStringStream now observes encoding.
Are these changes going to be merged to fixes_3_0? What first stable
version it is going to appear in?
As it turned out, Lazarus sources are affected by this change too, so we
need to get the correct {$IF FPC_FULLVERSION >= 30x0x}.
Thanks

Yes, in fact it does not need a server. A browser only needs some HTML and the pas2js generated js, which could be on your local disk. See here: http://wiki.freepascal.org/pas2js#for_the_browser Note that with Node.js you can run pas2js programs on the server too. > For 'server' side you then write 'as usual' e.g. cgi or other way available > (server-native binary) > > (Nothing stops really the server-side-native binary (e.g. written in Pascal) > from sending a pas2js transpiled program to the browser as a part of a 'html > page'/script, > but the line of separation is pretty clear here : this is like doing > Graeme's favorite GUI to non-gui portion separation ';) > but still YOU are doing the separation manually - you need to write BOTH > portions separately) > > For communication between the browser end and the server end, there are ways > covered > (AJAX ?) not much different than the usual (js in browser <-> > java/php/perl/python/server side js in server) LAMP stack does.
