Node streams are async (event driven), it's impossible to mix it with sync code. But you can acces stdin via process.stdin.fd
http://stackoverflow.com/a/9318276
But, honestly, i don't see reason to add rare features until anyone need it
from argparse.
If the file is opened sync before creating the stream, then it can be used either way. That is, the stream's .fd
property is available in the same way as process.stdin.fd
. The stream object has useful information about the file in addition to providing to providing async stream methods.

Honestly, probably this would be the best feature of argparse
and the main reason to use it, FileType
is awesome, and returning a stream in Node.js instead makes totally sense. This could also open the door to use other custom argument checkers...

Ported from python as part of argparse 2.0 (as process.stdout
for -
or fs.createWriteStream
otherwise).
Keep in mind that you can close fs streams with stream.close()
, and stdout (which shouldn't be closed) conveniently doesn't have such method.
Maybe it needs some examples, I feel like FileType is one of the less clear parts in all of this.

Does this also works to read files?
from argparse.
yeah, FileType('r') to read and FileType('w') to write, same as python
from argparse.
Great! :-D
