Re: [v8-users] Questions when adding global object
Thank you!
We decided to temporarily remove the console block.
Really appreciate your help!

On a closer look at the code, it seems that you *have to* provide a
ConsoleDelegate if you want console.log to do anything.

Yes, of course.

Re: [v8-users] Questions when adding global object
Sorry, I only know what I see in the code. I'm not sure if/how
ConsoleDelegate is supposed to be used via the regular API.
If you want to hack it, you can remove the entire { // -- C o n s o l e
block in src/bootstrapper.cc, that'll prevent the built-in console from
overriding the global template you're providing. Of course this approach
doesn't apply if your setup doesn't allow you to modify V8's source.
Maybe it's easiest to just keep the default console.log implementation,
letting it print to stdout and redirecting the output of the process to a
file?

Re: [v8-users] Questions when adding global object
And actually is the consoleDelegate exposed in the .h files in the include directory? I saw it is defined in interface-types.h but if I were to include that, it will lead to a chain of includes from /src.. Am I misunderstanding something? Thanks!

Re: [v8-users] Questions when adding global object
Hello Jakob, May I get some more directions for using the consoleDelegate? >From d8 files. I saw that we could make a console class and use set consoleDelegate to set console functions. But in our old way, we create a global template for "console" and using setAccessor to append functions to it. Since I don't want to introduce too much code change. Is there a way to keep the old usage (create as global template)? or is using consoleDelegate the only way to specify console functions? Again thank you so much!

Re: [v8-users] Questions when adding global object
V8 now provides its own "console" object, with the usual methods installed on it. Does it not serve your needs? You can override it by providing a ConsoleDelegate via the debug interface. The d8 shell (src/d8.cc) provides an example.

[v8-users] Questions when adding global object
Hello, we are working on upgrading v8 from 5.3 to 6.7-lkgr. But I recently found a strange behavior for one global object with name "console". In the old version, we have a global object "console" for logging info. But when upgraded to 6.7, the "console"'s callbacks functions won't get called. I tested if I change the name from "console" to something else, it will work as usual. I am feeling like that "console"seems to become a reserved word for the newer version? May I know if this is expected? And if true, is there any workaround to overwrite this behavior? we would want to keep our old "console" name.
