Httpie: HTTPie in Cygwin

[celevra]

Hi,

i've installed httpie on windows through pip.
I want to use it through cygwin but it only works through powershell or cmd.
I always get the error

http-script.py: error: Request body (from stdin or a file) and request data (key=value) cannot be mixed.

is there anything i can provide?

age = 100 ??
If it doesn't work try installing httpie in a virtualenv.

@celevra It looks like stdin under Cygwin doesn't present itself like a TTY so HTTPie thinks it's redirected from another program or a file. So it's probably a bug in Cygwin. What output does this command give you?

$ python -c 'import sys; print(sys.stdin.isatty())'

As a workaround, you could use the --ignore-stdin flag. And for convenience, it can be added it to your ~/.httpie/config.json under "default_options": ["--ignore-stdin"]. Then to enable the reading of stdin when you need it for particular invocations, it is possible to disable the flag again via --no-ignore-stdin.

@jkbrzt thanks for the fast answer.
the command gives me a False back.
Do you really think its a bug in Cygwin? Woudn't that be huge problem for other programms also?

the workaround works like a charm, thanks for that

[jakubroztocil]

@celevra yep, I think it's Cygwin. It might be that only Python is affected by that, but the sys.stdin.isatty() method should return True since sys.stdin refers to a terminal. I'm not a Cygwin user but it'd be worth reporting to its developers.

[hangtwenty]

If it only affects Python, _definitely_ a bug. If Cygwin just never presents itself as a TTY, I could imagine someone saying this was a design decision not a bug. But geez. What a deviation from normal Linux and bash expectations.

In any case, this is surprising ... but good to find. Oh, Cygwin...

[hangtwenty]

It's worth asking: should HTTPie check sys.stdin.isatty() and if it returns False, then default to --ignore-stdin (perhaps with a WARN-level log message)?

Python for windows is a windows console application, so it won't work well in msys/cygwin's ansi terminal.

You may use python for cygwin rather than python for windows,

$ apt-cyg install python
$ python -c 'import sys; print(sys.stdin.isatty())' # => True

Or, you may run python for windows with winpty:

$ python.exe -c 'import sys; print(sys.stdin.isatty())' # => False
$ winpty python.exe -c 'import sys; print(sys.stdin.isatty())' # => True

[jakubroztocil]

Thanks for the tips, @Arnie97. I'm closing this now as there's nothing HTTPie can do about that.
