Unless I am misinterpreting, seems 2x as fast ? Tested on Fedora Core 1.

PS. How about a runtime option to get rid of the annoying banner ? :-)

Perhaps one that doesn't create the element that you're trying to look up?

(Not meant as criticism. I think you're doing a great job.)

Here are the results from Mac OS X 10.3 "Panther":

DMDScript/GDC:
(does not compile yet...)
* Safari: "Netscape ns"
(end of page, just blank)
* Camino: "Netscape ns"
(end of page, just blank)
* Netscape: "Netscape ns"
(end of page, just blank)
* Microsoft IE: "Microsoft Internet Explorer ie
ScriptEngine JScript Build 3715"


The webpages gave scripting errors, outside of IE:

Safari:
> sieve.html:11: TypeError - Value undefined (result of expression ScriptEngine)
> is not object. Cannot be called.

Camino:
> JS error: ScriptEngine is not defined

Netscape:
> Error: ScriptEngine is not defined
> Source File: sieve.html
> Line: 11


After commenting that out and fixing the HTML to follow W3C standards,
here are some results in numbers (which varies a lot, just examples):

* Netscape 7.2: elapsed time = 3470
* Safari 1.2.4: elapsed time = 3419
* Camino 0.8.2: elapsed time = 2363
* Internet Explorer 5.2: elapsed time = 1922

Sounds cool. Is there an API to the dscript engine? I can't tell browsing the source directory how to plug it into an application.

Generally I was googling on *script names, looking for one I could use.

It does come with source. Just use // <g>.

To add a function, just add it in like the ones in dglobal.d. To create a new object type, I'd just copy the code in protoerror.d and modify it to suit.

Same here, on Windows XP and 2000. Oddly, on Linux everything went smoothly.

Okay, I added a patch to only show the banner in verbose mode...


I also added a small test.ds program, to avoid the default (error).

And a proper manpage, as usual... (?)
http://www.algonet.se/~afb/d/d-manpages/ds.html

Updated the SRPM with those changes: http://www.algonet.se/~afb/d/dmdscript-1.03-3.nosrc.rpm

PS. I didn't use "println", since it didn't work with Mozilla JS...
     For some reason "print" adds a newline in JS, making two above.

In article <csp4pm$o45$4@digitaldaemon.com>, Walter says...

Think one day the DMDScript engine will be available as a truly just-link-in
library?  I can't help dreaming of code like:
#
#  private import etc.dmdscript.dmdscript; // or... something
#
#  static this() {
#    // Where Foo is a class implementing some standard interface
#    // Maybe IScriptObject or the like
#    DMDScript.registerObject("Foo", &(Foo.scriptFactory));
#  }
#

Any chance of it?  Or is that do-able now with some boilerplate?
