You have to be aware that JavaScriptCore is only a small part of WebKit - it's only a javascript interpreter i.e. it can execute JavaScript scripts in source format. If you want to build a browser you have lots more to do, including building the html parsing and rendering engine and this stuff so far only works on MacOS (and Symbian, I guess, thanks to Nokia's work). For learning about JavaScript itself, either google around or read O'Reilly's "JavaScript - The Definitive Guide". For how to execute scripts - look at kjs\testkjs.cpp (which, on windows, builds as testkjs.exe) and is a simple example of how to load a javascript script from a file and execute it. You would have to build something similar on Palm except: * Palm OS doesn't have stdout so you would have to substitute it with something else (e.g. writing to a database or a file on SD card or just scrolling to the screen) * Palm OS doesn't have command line so you would have to build some simple app that allows picking javascript file to execute from database or a file on SD card and then execute it The approach I would suggest: get the WebKit sources which Nokia used as a base of their version (I assume they just branched at some point and did all their modifications from one, stable point) and do a diff against Nokia sources. That will give you the best idea on how much and what kind of work is required to port the whole thing to another OS. history.back() is a method call on history object which is registered with JavaScript interpreter by WebCore (see WebCore\khtml\ecma\kjs_window.cpp for how it's implemented in latest sources) -- kjk _______________________________________________ webkit-dev mailing list [email protected] http://www.opendarwin.org/mailman/listinfo/webkit-dev
