Re: [webkit-dev] nested scopes
Darin, You are right. I was using SpiderMonkey before switching to JavaScriptCore. And i am developing on Android plaform. on Android, public API is not compiled into the libraries.. so i am using kjs API from Interpreter.h. Is there anyway i can implement scopes using the private/internal API. any pointers? Raj PS: i had sent this mail to Android list, but didnot not get any response. So i thought its better to talk to the original developers. If you are wrapping JavaScriptCore you should use the public API, not the internals. The public API is in headers like JSBase.h, JSValueRef.h, JSObjectRef.h, and JSClassRef.h. However, the public API doesn't have any concept of explicitly creating scopes; instead scopes are created by the engine automatically for the various language constructs that require them. An explicit way to create a scope doesn't seem to be necessary API for use of the engine, and there are other reasons not to add it — different scopes have different semantics in the language. I'm assuming this requirement is baggage from whatever engine previously implemented this js_push_scope API. -- Darin ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
[webkit-dev] nested scopes
Hi all, I am developing a wrapper API on top of JavaScriptCore for integration with my application. Here is an overview of my API. In my application scripts are executed and variables are defined in different scopes. This example shows the functionality needed. js_init(); - initialize js_set_var(abc,2); - set abc=2 in global scope js_push_scope(); - create a new scope js_set_var(abc,4); - set abc=4 in new scope js_print_var(abc); - should print 4 as we are in new scope js_pop_scope(); - pop most recent scope. i,e. the new scope js_print_var(abc); - Now it should print 2 because we are back to global scope. My question is what should i be doing in js_push_scope and js_pop_scope so that a new JavaScript scope is created and destroyed. I have seen that there is a ScopeChain.cpp/h .. but its not very clear as to how to use them.

Re: [webkit-dev] XML Events in WebKit
Guys, thanks very much for all the comments. let me be more specific about my problem. i want to add multimodal capabilities to the webkit. I want to trigger (or communicate with) an external app based on events happening in the xhtml document. Also i want to insert custom events into the XHTML context based on results from the external process. Is there any way i can do this with current version of webkit. any pointers on what needs to be done?

[webkit-dev] XML Events in WebKit
Hello all, Does webkit support the XML Events specification http://www.w3.org/2001/xml-events. To be specific, some thing like the following is valid for WebKit? ev:listener event=focus observer=mytextbox handler=myhandler/ thanks in advance Raj ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev
