hi, im working on js code coverage implemented directly to the compilation process of v8. at first stage i need to "snatch" the code at the start of compile function , do some transformation on the code directly (add prints essentially) and switch it with the original code , to be compiled as usual. so far i have encountered 2 ways to ways to extract the string value from handle<Internal::String> , one is by using GET , the other by toCstring method of the class string. efficiency aside, assume we use the Get method. now we have got the code and successfully done the transformation we needed. now i want to create Handle<Internal::String> taht will contain this string instead of the original. unlike the v8::String , Internal::String does not have a New option. so i've discovered i can use the original Handle<Internal::String> to get the isolate , and from there i go the the factory and create a string from ascii. it looks something like this : source = source->isolate()->factory->newStringFromAscii(cStrVector(newJsCode,length));
now , the compilation fails because it arrives to isString() function along some test and fails there (some characters in the print are not recognized) . i have 2 quesstions: 1. should i use NewStringFromUtf8? or is there another way to create handle<Internal::String> ? 2. i don't yet understand what is exactly isolate? can someone explain it? and is my new "source" variable will catually contain the same isolate as the original? -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users
