Change "environment" to "env" in launch.json

[kieferrm]

Moved from microsoft/vscode#9733:

• VSCode Version: 1.3.1 with C/C++ extension 0.7.1
• OS Version: Linux

Steps to Reproduce: Open launch.json and hover over "environment":

I followed the example, but I'm getting Incorrect type. Expected "array". This page https://code.visualstudio.com/docs/editor/debugging says I should use "env", but I guess that's because it's for Node.js debugging and I'm trying to debug a C++ application?

@kieferrm the environment variables are name/value pairs within an array. Proper usage should be:
"environment": [{"name": "squid", "value": "clam"}, {"name": "squid1", "value": "clam1"}]

It is expecting an array which is defined by [ ] and then each name/value pair is within { }.

Ah I see thanks :)

What do you think about renaming this to env and make it behave just as with node.js debugging? This would make it more intuitive IMHO.

[pieandcakes]

@jhasse we can take it into consideration. I feel like "environment" is very clear and since it is already there, it doesn't need to be typed :)

I have also updated the help example to include the array brackets.

Yes, so rather than have a consistent way to do the same thing across different languages (since environment isn't part of the language but...well...part of the environment) let's make it different for each language. And the confusion caused caused by the differences is totally worth not having to type out "environment" because it's already there.

@m-mcgowan @jhasse We will consider it for a future release.

Hi,
How can I access the env or args variables in C++ in my program?
For example, I want to access args[1] in my code or "name": "sceneFile", how can I make it happen?

Thanks,
Chunting
