Write GLUEscript modules in FreePascal or access functions in dll/so ?

[PaulANormanNZ]

HI,

Is it possible to write appropriate modules for GLUEscript in another envornment like FreePascal which can produce dll or so?

Or is it possible please to load functions from other non GLUEscrit dll or so  ?

The next version will contain ctypes (available in SpiderMonkey 1.8.5)
which makes it possible to call foreign functions in other DLL's.
Is it possible to use SpiderMonkey in FreePascal?

That is going to be truly amazing, that will really strengthen GLUEscript!

Looks like that is happening here: http://delphi.mozdev.org/javascript_bridge/faq.html

There has been information added within the last few days.

There are other JavaScript or EMCA scripts engines available to FreePascal (Lazarus), 

http://besen.sourceforge.net/ and so on, but I am hoping to make things that might support what is already happening, rather than branching off in other directions.

FreePascal can basically embed forms in dll / so or make utilities that can have forms in them and print results to the command line etc as well. Windows/Linux/MacOsx and  more.

Actually it looks like there is at least a partial implementation of
this already...

http://code.google.com/p/fpcjs/

This links to the .pas file which defines the class objects, I realise
that it is object pascal but does it look at all like what you would
anticipate was helpful to making a .dll that could be used GLUEscript
to directly provide JavaScript objects/functions?

Hi,

With the "gluified" libraries like gd etc.. when glue uses "require" as in
var gd = require("gd");
What is it expecting to find exported from say bin/modules/glue_gd.dll

FreePascal can create most data structures that C or C++ can.

Or is this too complex to be spending time trying to explore perhaps?

The interface Poco::Script::JavaScript::SpiderMonkey::ExtensionInterface
must be implemented by all glues.
These are the virtual methods:

virtual Object initialize(Object& obj) = 0;
virtual std::string id() const = 0;

id() returns the name of the glue. For example: gd will be returned by
glue_gd.dll
initialize is used to initialize all JavaScript classes. The object that
is passed is the module object which is returned by the "require" method.

GLUEscript uses the dynamic class loader from the POCO framework.

Thanks Franky,

I'll explore that when I can and see if anything is realistiacally
workable from FreePascal.

I have had a preliminary look at .h header conversions to .pas, but I
am not sure how successful this could be over all yet.

However I am thinking that the ability for GLUEscript to load from
outside .dll, coming in version 0.2 may be all that is realistically
needed?
