usage: px [-h] [-L] [--pre FUNC] [--post FUNC] [-i MODULE] [--stack] [-x X]
expr [file ...]
My Python version of `awk`
positional arguments:
expr python expression to evaluate
file input file(s) (use `-` for stdin)
optional arguments:
-h, --help show this help message and exit
-L, --linear linear mode
--pre FUNC preprocessing applied to cells
--post FUNC postprocessing applied to result object
-i MODULE from MODULE import * (separate multiple modules with `,`)
--stack stack all files into one
-x CMD execute arbitary python command before exit
--no-none don't print None items in results
--bo [binary output] keep output in python object format. (useful for piping to another px process.)
--bi [binary input] parse input in python object format. (useful for piping from another px process.)
examples:
px 3+4
px -L x+y a.txt b.txt
px -L "f'name:\t{x}'" <(ls)
px -i math 'sin(pi/3)'
px --pre=int sum(x) series1.txt
px -L -i json --post dumps "{'name': x[4:].strip(), 'size': x[:4].strip()}" <(ls *.pdf -sh)
px --pre="lambda a: a**2+1" "[X/Y for X,Y in zip(x,y)]" <(px [4,3,3]) <(px [1,1,3])
px -i numpy,matplotlib.pyplot "plot([1,2],[4,2])" -x "show()"
