Re: [v8-users] Why does CompileUnbound require a context?

I discovered there's at least one more thing that CompileUnbound does with the current context. There's a call to isolate->debug()->OnAfterCompile() in Compiler::GetFunctionFromEval, which sends the Debugger.scriptParsed event--if the current context is being debugged. If the current context is

[v8-users] Minimal example of the v8-inspector c++ api

I've been trying to use the v8-inspector C++ api in my app, but it doesn't seem to be working. I have a feeling I'm probably misunderstanding something simple due to the lack of documentation and comments in v8-inspector.h. Could someone create a minimal example of using the v8-inspector c++

I've got a V8 library on github that isn't abandoned: https://github.com/tbodt/v8py. I've gotten pretty much everything to work with it. It's a Python extension module, though... Hope this helps. ~Theodore On Wednesday, December 21, 2016 at 9:33:02 AM UTC-8, kent williams wrote: > > I think

SetPrototype and Set can fail, so they return optionals. FromJust asserts that the optional is not empty (and crashes the program if it is empty). On Monday, December 19, 2016 at 10:18:31 AM UTC-8, kent williams wrote: > > That example has some weird: > Line 11341: > >

[v8-users] Re: Missing symbol ___asan_version_mismatch_check_v8

That didn't work. V8 insisted on linking with the asan runtime included with it's special version of clang, so mkpeephole wouldn't run because it couldn't find ___asan_version_mismatch_check_apple_800. I'm going to try playing with the executable path. -- -- v8-users mailing list

[v8-users] Re: Missing symbol ___asan_version_mismatch_check_v8

Well, I looked a little more closely at the compiler options and discovered that my library is not, in fact, getting compiled with ASAN. Only V8 is. Now the problem is that if I compile the library with the same compiler as V8, it can't find @executable_path/libclang_rt.asan_osx_dynamic.dylib,

[v8-users] Re: eval in current C++ scope

A HandleScope does not store any key-value pairs. It sounds like what you need is to create multiple Contexts. If that's not quite what you want, I'd suggest creating objects using Object::New and using them as the receiver in CompileFunctionInContext. ~Theodore On Wednesday, November 23,

[v8-users] InternalFieldCount seems to be ignored when ConstructorBehavior is kThrow
