Referring to environment variables from binding.gyp (node-gyp)

问题

I am using node-gyp, and I would like to use the value of an environment variable inside my binding.gyp file.

Here is the hard way (list context):

'<!@(printf "%s" "$FOO")'

But is there an easier way?

回答1:

To the best of my knowledge from working with gyp (the parent Google's project, not the one that ships with node https://code.google.com/p/gyp/). You can access environment variables the same way you would have in the shell.

For example:

'$(FOO)'

Will return the data stored inside of FOO.

To get that information in a list context, I don't know if there is a better way than what you did, except for perhaps a more concise way:

'<!(echo $FOO)'

You can find Google's gyp input format reference online here.
