Python module to implement xargs-like (but better) functionality.
The POSIX utility xargs is fantastic.
However, we can do better, particularly if we are using a programming language that offers more than your average shell... like python.
The included python file implements a library. This library offers the following features over xargs:
- Possible to implement a pipeline.
- You don't need to worry about terminating anything (because it's Python; Python knows where its strings end).
- You don't need any special data structures; just lists of lists of lists of strings.
Is it perfect? Nope.
Is it pretty darn good? I think so, yes.
Example usage:
xargs([
[
['infile1',], ['infile2',],
],
[
['grep','CCACTACTT',], ['grep','CCACTACTT',],
],
[
['fold','-w', '10',], ['fold','-w', '10',],
],
[
['outfile1',], ['outfile2',],
],
], 1)
