ronin does not work on windows

[nussbrot]

Hi,

i'm evaluating ronin as a possible build system for a FPGA project. One of my needs is that it works on Linux and Windows. That's why i look for build systems based on python.

ronin uses blessings, which in turn uses fcntl. Both of these modules are not cross-platform.
I'm wondering why you're using those modules and if you intended ronin to be cross-platform?

At least your PyPI entry has the tag 'OS Independent'.

Thanks for considering Ronin, am happy to help make it work better for you.

The whole point of Blessings, I thought, was to allow support for multi-platforms. Have you actually tried it in Windows? What error do you get? It's definitely possible to make it optional.

Yes, i have tried it on Windows. The error is:

PS D:\entwicklung\ronin> python .\build.py
Traceback (most recent call last):
  File ".\build.py", line 1, in <module>
    from ronin.cli import cli
  File "D:\tools\Python3.6.5-amd64\lib\site-packages\ronin\cli.py", line 17, in <module>
    from .contexts import current_context
  File "D:\tools\Python3.6.5-amd64\lib\site-packages\ronin\contexts.py", line 20, in <module>

    from blessings import Terminal
  File "D:\tools\Python3.6.5-amd64\lib\site-packages\blessings\__init__.py", line 7, in <module>
    from fcntl import ioctl
ModuleNotFoundError: No module named 'fcntl'

I don't know about blessings multi-platform capabilities, but it tries to include fcntl, which is not portable, afaik. See here for example.

If I can help you somehow let me know.

Also, you cannot simply install fcntl on Windows:

PS D:\entwicklung\ronin> pip install fcntl
Looking in indexes: https://pypi.org/simple
Collecting fcntl
  Could not find a version that satisfies the requirement fcntl (from versions: )
No matching distribution found for fcntl

Thanks, very clear. Do you feel like tackling this yourself and submitting a PR? If not, I might find time next week. I don't think it should be too hard to figure out how to make colors work on both Windows and *nix.

I have solved this uninstalling "blessing" and installing "blessed" https://pypi.org/project/blessed/ then in \site-packages\ronin\utils\messages.py at line 18 changing "from blessings import Terminal" to "from blessed import Terminal"

@riccardolasagno That's great! Could you submit a pull request, please?
