Pandashells is a set of cli tools that opens up the power of the python data stack to the bash prompt. Brings dataframe manipulation, visualization and statistical modeling to the unix pipeline workflow.

Since you created this tool, you can put "Show HN:" at the beginning of your submission's title. That will make it show up on https://news.ycombinator.com/show

I'm a total HN noob. Don't see an option for editing the post. Am I just blind?

There is no requirements file with pandashells because some of the tools only require the standard library, and there's no sense installing unnecessary packages if you only want to use that subset of tools.

This is a terrible idea. One of the main features of package managers is dependency management. If you want to be as minimalistic as possible, separate the tools into further packages (some of which have their requirements laid out properly, and some of which only require the standard library).

Try the extra capabilities parameters in setup.py, so the user can selectively install what they'd like:

    extras_require = {
         'param_name': ['pkg1', 'pkg2'],
     },

They then can be used like so:

    pip install package[param_name]

thanks mixmastamyk. That's a good suggestion.

Thanks for the feedback. As you may know, getting matplotlib to work properly with backends like TkAgg can be quite a chore when installing using pip (non-python libraries are needed). The Pandashells install process could be improved. I intend on creating a conda package for Pandashells that should handle the dependency issue you raise, but I just haven't had time to do so yet. I am hoping the detailed examples in the docs will suffice until I do.

Why focus on TkAgg support? Just write graphics to a user-specified file.

This looks amazing! The amount of time I spend writing short python scripts to manipulate data in simple ways is way too big, and this looks like it might fit my needs precisely. Thank you for creating this.

This is great! Do you want to make a Conda package for this or shall I?

robdmc7• 11 years ago

I would love help making a conda package. I've never done that before. I didn't spend a lot of time looking, but I didn't find conda packages for some of the dependencies (e.g. gatspy). If you now how to work around that, I'd welcome the help.

Thank you very much for your work. One question: I've never used PowerShell cause I'm UNIX user but isn't PowerShell capable of doing something similar (piping the objects)?

robdmc7• 11 years ago

I'm not sure. I've never used PowerShell either.
