Good day all,
As I promised, will keep you updated.
On foxite I also made the same announcement I posted here, regarding the
X# Roadmap for 2019.
Tom Knauf, then responded with the following. I also include my reply.
Hope it is of interest to some of hopefully all:
> What I am mising is something like execscript(cCode).
> I can have any code including if then, variables, calls to own
functions,... in a char variable and it will be executed.
> We built a complex script system to allow user their own workflow and
never found a good replascement in c#, windev,...
> An own parser would be extremly much work to do.
> Any plans/ideas on that ?
Hi Tom,
No plans/ideas are needed. X# already contains xsScript. The following
will already run:
*File:HelloWord.prgx // Note the x in the file name if you want it to
run directly.
CLASS MyHelloWorldClass
PROTECTED txtAS STRING
CONSTRUCTOR()&& The Init of VFP classes
txt :="Hello World from Class"
RETURN
PROPERTY SpeakAS STRING GET txt&& Access/Assign = PROPERTY GET/SET in X#
END CLASS
FUNCTION HelloWorld()AS STRING
RETURN "Hello World from Function"
PROCEDURE HelloWorldProc()
System.Windows.Forms.Console.Writeline("Hello world from Procedure")
RETURN
FUNCTION Start()AS VOID
?HelloWorld()
HelloWorldProc()
?MyHelloWorldClass{}:Speak
RETURN
*End of File:HelloWorld.prgx
In your program you just have to
obj := xsScript(cCode :=FileToStr("c:\...\HelloWorld.prgx"))
&& Note obj will now hold an in memory compiled version of HelloWorld.prgx,
&& that you can happily pass anywhere in your application,
&& no "parsing" of the script needed anymore!!!!
obj:Start()
You now speaking to the Clipper guy who already work the last 25 years
exclusively on what you describe above, called in the
Clipper/VO/Vulcan/X# world Data-driven applications. I have a slightly
different approach, I store my scripts in a Relational Database and not
in zillions of txt files.
I am busy writing a series on the concept of which the first 12 of
[Insert end of series here] articles are already available in the
downloads area of the X# webpage.

Would you be interested in a joint venture, where we take the best of
both those worlds
Solution := ((XBase := VFP * Clipper fork) * (Knowledge := Tom * Johan) *
(Environment := X# * .NET))
? Solution:ToString()&& A 100% .NET solution that runs at 99% of the speed of a compiled
Application.NET, but was created in 1% of the time it will require a
developer to roll out in PRG files?
Looking forward to hear from you or anybody else using data-driven
techniques,
