digitalmars.D - Anyone done working internal IE with D?

I could get events with function pointers but this one worked even slower, fair
to say unresponsive. The only thing I could do after displaying a web page is
endtasking the program or click the close button and wait 3-4 minutes to
close... Am I missing something? By the way it would be cool (I don't know is it
possible, but would be very cool) to have internal browser and have access to
it's javascript trough dmdscript.

I recommend the Intel profiler VTune. You can also try the -gt flag to enable profiling http://www.digitalmars.com/ctg/trace.html. I haven't tried that flag myself but it looks very useful. -Ben

I think the -gt flag is useful. The primary feedback output ends up in the 'trace.log' file. As far as the bad performance, I would guess it has mostly/all to do with memory management, like making lots and lots of allocations when perhaps you could allocate outside of loops and use array slicing inside the loops more. For example, load the entire page into a buffer, slice it into it's component parts and pass those to the API's. - Dave

It's more than useful. Ever wonder why DMC++ has held the speed record for compilation speed for the last 15 years? Why DMDScript is twice as fast as jscript? If you want to make your app sing, -gt is the answer. <g> P.S. I wrote -gt because existing profilers at the time were notoriously difficult to use. Most required one to slog through a 50 page manual to figure out how to use, and there was a lot of work involved in setting things up. As a consequence, nobody used profilers. I wanted one that was as simple as throwing a command line switch. -gt succeeds in that, but it's still rare for anyone to use it. I'm at a loss as to why. Sometimes I wonder if the reason is because people overlook it thinking "it can't be that easy" because they are still accustomed to profilers being a big fat pain to learn how to use and apply. P.P.S. -gt is not a terribly sophisticated profiler, but I've used it extensively and it gets the job done.

You're right - it is more than just useful, and is a great tool. I hadn't thought of it until you posted this, but up until -gt I didn't use profilers that much because they are generally more of a PITA than they are worth. Now I build anything time-critical with -gt during development because it is easy to use and gives good feedback, fast. Another upside is that it encourages better structured programming style to get the best feedback. Thanks for this feature, Walter! - Dave

You're welcome! Though of course, it's paid back to me personally far more than it ever cost to write. That anyone else can get some use out of it too is just gravy.

Thanks, Charlie.

We are actively developing HTMLayout now. Various wrappers in particular.
And I hope I'll have a chance to create a D wrapper.

There are couple of places where D will definitely win e.g. behaviors -
custom drivers for HTML DOM elements.

And were you have seen these standards? First: All CSS specs are recommendations. Browser teams are free to choose what level they support. Second: There are almost 200 attributes in CSS Level 3 now. Half of them dependent from each other. Third: The complexity of the spec is close to the level when system starts governing by deterministic chaos rules. Fourth: CSS recommendation as a system of rules is a fuzzy set (math) as soon as it contains phrases like "HTML UAs may apply ...." Axiom: there is no browser (UA - user agent) which conforms spec. in present and there will be no such UA in the future. Andrew.
