[nodejs] How do I set breakpoints in, and debug, Node.js C++ code on Windows?

I'm familiar with writing C++ libraries for Node.js, but have never figured out how to debug them using breakpoints, etc. Most of my libraries have been simple enough to not need any real debugging. I'm on Windows and I am unsure of how to go about doing this. Will I need something like gdb, or

[nodejs] Re: How do I set breakpoints in, and debug, Node.js C++ code on Windows?

It looks like the solution created by vcbuild.bat, on Windows, is able to just be opened in Visual Studio. The debug settings are all configured and ready to go, too. Pretty sweet! On Wednesday, April 30, 2014 5:20:00 PM UTC-5, Ryan Cole wrote: I'm familiar with writing C++ libraries

[nodejs] How to run node tests on Windows?

Hi all, I'm trying to run the unit tests for node, on Windows. I'm using `vcbuild.bat tests`, but all it does is rebuild the project, it does not run any tests. Is there anything additional that I need to be doing to run these tests? Thanks, Ryan -- -- Job Board: http://jobs.nodejs.org/

Nevermind. For whatever reason, the tests are running now. Ryan On Tuesday, April 29, 2014 10:14:28 AM UTC-5, Ryan Cole wrote: Hi all, I'm trying to run the unit tests for node, on Windows. I'm using `vcbuild.bat tests`, but all it does is rebuild the project, it does not run any tests

[nodejs] How to properly pass LocalObject as function param?

In a C++ addon, I've got a function in which I instantiate a LocalObject. I want to pass that as an argument to another function. Should the argument be passed as a LocalObject, or PersistentObject? I'm unsure of when I should use either of those. Thanks -- Job Board: http://jobs.nodejs.org/

Re: [nodejs] How to properly pass LocalObject as function param?

PersistentFunction, so that makes me think I'd use PersistentObject to cross those function calls? Thanks, Ryan On Sunday, November 11, 2012 8:53:20 PM UTC-6, Ben Noordhuis wrote: On Mon, Nov 12, 2012 at 2:35 AM, Roger WANG roger...@linux.intel.comjavascript: wrote: Ryan Cole ry...@rycole.com

Ok thanks for the help. I think through this code I'm writing I've at least nailed down when to use those two handle types. Thanks again! Ryan On Sunday, November 11, 2012 9:19:44 PM UTC-6, Ben Noordhuis wrote: On Mon, Nov 12, 2012 at 4:16 AM, Ryan Cole ry...@rycole.com javascript: wrote

[nodejs] Returning Error from within C++ addon?

I'm writing an addon in C++ and would like to pass an Error to a callback function if an error occurs. I see how to throw exceptions, but in this case I simply want to pass an Error. I've looked through v8 docs and node.h but don't see any examples of returning an Error. I know this must be

[nodejs] Acceptable actions to take inside a C++ addon's initialization function?

I'm getting a seg fault core dump in a simple module. I can eliminate the seg fault if I comment out a ThrowException call in the initialization function. My code: https://gist.github.com/4053133 (line #28) Things makes me wonder, what are the acceptable actions to take inside of this

[nodejs] When using Buffers, do the read methods also use the same initial Buffer heap memory?

I'm writing a module that parses data as it comes in from a tcp socket. When reading out data from a Buffer, is it better to stick to the slice method because of the fact that it uses the same heap memory as the initial Buffer? Do the read methods do this, as well? I've just assumed that the

Roy, I notice you mentioned this early in the email chain. I should have tried it earlier. It fixes the issue. I wonder why the ldflags in binding.gyp does not properly set this up, in my case? Or, is LD_LIBRARY_PATH just another required step no matter what? Also, I did not know about the ldd

[nodejs] Wrapping a C++ object, and adding properties directly onto args.This() = incorrect?

I'm wrapping a C++ object and then appending some properties. I'm calling Wrap(), and then Set()'ing the properties directly onto args.This(). This does not look or feel right to me, so I'm inclined to think I'm doing it wrong. I'm so new to this that none of the examples are standing out to me

I have adjusted the binding.gyp file to include the linker settings required for including the HDF5 libs I need. I believe that the current gyp file mirrors a Makefile that I am able to get working, for HDF5's stand alone compile. The only difference is that you're supposed to run the HDF5
