c3c --print-env feature request

[alexveden]

For tooling prospective, it would be nice to have a c3c option that prints its build environment (maybe in json format):

1. c3c version
2. standard lib path used for project (must have for LSPs)
3. c3c path
4. build output path
5. environment flags state which is used by attributes, i.e. $if(env::LIBC)
6. Anything else what could be altered by project.json maybe?

This is a low priority request, though.

Can you show a mockup of what you want?

I think simple JSON output would be sufficient:

{
"c3c": {
  "version": "0.6.5",
  "stdlib": "/some/path",
  "c3c_exe": "/another/path/c3c.exe",
},
{
"project": {
  "path": "/current/project/path",
  "target": "current target",
},
{
"environment": {
  "system_path": "$PATH",
  "os": "win32",
  "variables": {
   // text should match to @if() attribute text in c3 code
    "env::POSIX": false,
     "env::win32": true,
     "LIBC": true,
     "SOME_USER_DEF": true, // in project.json if it's allowed
}

}

}
