Does the html contain all of the style that requires including images (if
existed) ?
Please note that the CSS need to be set for printing that is a bit different
then viewing.

It contain examples on how to use webkit (please look at them, they does all
you require), but you do not require to use the whole API, only small parts
of it of  webkit and the printing
API .

I'd even propose that one uses var as soon as he plans to change the
array. It makes the code easier to understand.


Indeed. It indicates that you expect the array to be changed.

The CSS files are in .css extension files.
I don't have concern about this if I use th wkhtmltopdf lib. In my
tests everything works fine.

Printing API... sorry, are you sure? The Printing API can convert
files at another types?
Could you send (in private) a little example for this, please?

[fpc-pascal] Javascript in Desktop Applications

A cross-platform solution is to use one of libsee or BESEN.

The latter is implemented in 100% native Object Pascal.

BESEN is very, very, very  well written but I can't seem to get any
indication how to use it in my project.  I would love FPC to include a
JIT system for JS or Pascal.  IMO, FPC absolutely needs a scripting
FCL going forward.  BESEN seems like the right guy for the job, but I
suspect he's burned out :-(  I think he had memory concerns too.

Does anyone have any BESEN examples that integrated actual FPC units?
It seems like all the samle js units are self contained with no
interface to system or GUI units.

Including JS support on my project would enable people to leverage
exiting "proven" technologies which would make for easier/allowable
for adoption in working groups / houses where selection of language is
restricted to language of the day :-)  Taking this statment and
applying this across the board, it would be an easier sell for
adoption of FPC/Lazarus with JIT support.  Personally, I'm thinking
along the lines of Web RAD down the road...

Well, if you can't get BESEN to work, libsee definitely does.
I even have an article on how to do it.

Actually fpcjs is the first project that I, (myself), have seen that
addresses the gateway issue of accessing application level methods.
Granted fcpjs (currently) only supports one type of callback(variant
array):variant.  The only issue I see is having a quasi fpc/js design
restriction in developing apps with no OOP - coding low-level linear
methods(for register) with maps to JS object counterparts.  The other
MAJOR issue is that callbacks via Register are not working on Linux
!?!.   Docs said they needed something about native registration.  But
this project looks lightweight enough on its face.

I'm at a point in my project where I think I am needing something like
this.  In an ideal world, any application level scripting engine
should know how to interface with FPC objects @ runtime w/o variants.

Currently, my largest problem is  because without things like scripting :
  * Admins must rebuild the service exe every time back-end objects
are modified.
  * Production environments where each binary is installed on a
different device across the network cluster(s)/node(s) will have
different versions.
  * Auto-build or auto-updates via distribution system will most
likely lead to problems for either us or for Admins during deployment.

The use of a scripting engine would resolve these problems.

Hmmm...  Mozilla is open source... :-)  We are free to port the
Scripting Engine to Pascal as long as we have the source? no?
