Input from standard input doesn't work (on Linux) about xdot.py HOT 9 CLOSED

Unfortunately one can't reliably omit the hyphen, as there's no way to detect when stdin will have a graph: stdin might not be a tty, but still not have pipe, as often is the case when starting xdot from application menu.

But I've fixed the instructions as suggested.

@zxgio, @coroa, Thanks.

@jrfonseca could you make a bugfix release to PyPI please? This bug is very annoying.

from xdot.py.

@mgedmin I tagged a new release and pushed. Hopefully it should pop up on PyPI shortly.

No luck -- https://travis-ci.org/jrfonseca/xdot.py/builds/427718100 -- it will take me a bit longer.

Oh yeah, that doesn't look fun!

(I was always curious: people who rely on CI builds out of tags to make releases, how do they deal with release process failures? Bump version and make a new tag? Do the release manually Just This Once(TM)?)

(The way I do releases is I don't push the git tag until after twine upload succeeds, so I can iterate and fix my make release rule in my Makefile.)

from xdot.py.

I often do git push -f to force a new tag. Indeed I ended up doing a manual release. The reason I didn't do it immedaitely is that not all my machines are setup with pypi credentials and what not. At any rate it's done now.

✨ Thank you! ✨

Thank you! I'm new to this library. From the code I can see that even if no input file is given you'll still have to type '-' as the filename, but README says "Usage: xdot.py [file]", which is a bit confusing. Maybe "Usage: xdot.py (filename | - )" is better. Otherwise we can just modify the code so that we don't need the hyphen.
