Through various sources (ie, googling & github) I've finally got a bit of a
grasp of the flow for connecting chrome dev tools to my v8 app. (which is
using a pretty recent HEAD build I've built myself with all default
settings other than compiling as a static lib[s]. v8-version.h says 7.0.0.0)
I connect via an explicit url (can't quite get json/list/ to show up in
chrome yet)
*chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=127.0.0.1:8008*
(Not sure how relevant the v8only=true and experiments=true are, couldn't
find any documentation on this)
This connects to my websocket, and I pass all messages straight to
*Session->dispatchProtocolMessage*
My channel then gets *sendResponse's* in return, which I send back to
chrome over my websocket.
Chrome dev tools shows essentially an empty debugger, no sources, no
console output, no errors...
The responses my isolate/context sends back, suggest maybe I have some JS
symbols/modules missing, which maybe I need to implement?
I'm kinda assuming this, as the debugger. methods succeed, but things like
*Inspector.enable* (which I haven't found anyone implementing, but some
people are implementing Inspector objects, just with different methods) fail
*Chrome tools message: {"id":16,"method":"Inspector.enable"}*
*Channel response: {"error":{"code":-32601,"message":"'Inspector.enable'
wasn't found"},"id":16}*
Is this why chrome isn't proceeding with anything?
Am I supposed to implement these, or perhaps are they missing from my
native blobs when I built my v8 libraries?
My overloads of the inspector client functions like *runMessageLoopOnPause*
aren't
being called, but I assume that's just because I haven't gotten to any
stage where commands are being evaluated?
Below is what I get when I connect chrome, but then it just sits there :)
Thanks for any pointers in the right direction!
