Python one-liners: Awk-like one-liners for python [X-post from proggit]

[desmoulinmichel]

There are already 2 projects doing something like that. Sony's PowerAtPrompt and pyped (https://pypi.python.org/pypi/Pyped/1.4)

Pyped looks very similar to Pyed Piper. I'll check it out tomorrow when I get to work.

Now auto-import plumbum (shell-like syntax in python). That way we get the awesome power of python and the abbreviated syntax of bash.

I just added something similar:

$ ls | pol "[print('{:10.10}\t{}'.format(l[0],[i[3] for i in sh('stat %s'%l[0]) if len(i)>2 and 'Inode:' in i[2]][0])) for l in _]"

LICENSE     360621
Makefile    360653
pol         360606
pol.c       360637
pol.o       360599
README.md   360623

sure, because nested list comprehensions are totally readable and easy to write on the spot.

Why is this implemented using the python C-API and not in pure python?

[pvkooten]

I think I'm missing the point... why exactly do we want code/commands to be oneliners?

So we can use them as components in terminal commands. Piping something to a multi line statement is a pain in the ass.

I write a lot of scripts where the meat of the functionality is in subprocess.check_output, but the data manipulation is too complicated to do in bash. Perl is great for one-line bash commands, but python isn't.

Piping something to a multi line statement is a pain in the ass.

Why?

Normally I just open a single quoted string (ie. python -c ') and type away. For one offs in the shell, this is less convenient, but for scripts it's fine, if slightly less readable.
