Better python CLI integration
Better scripting with python
Haven’t you ever missed writing perl one liners? Or maybe you’re more familiar with python than all the options of find, but like the text interaction paradigm? pyli aims to make it easier to use python and all it’s batteries in conjunction with your favorite hangout: the shell.
pyli is available via pip:
pip install pyli
Or directly via git and setup.py:
git clone https://github.com/thenoviceoof/pyli.git cd pyli sudo python setup.py
Let’s do some warmups:
pyli "2+2" # bc cat file.txt | pyli "line if 'string' in line else None" # grep cat file.txt | pyli "sum(len(l) + 1 for l in lines)" # wc -m
And now something more complicated:
log | pyli "str(time.time()) + ' ' + line" # time stamping a line cat file.txt | pyli "set(w for s in nltk.sent_tokenize(contents) for w in nltk.word_tokenize)" # bag of words a file cat file.json | pyli "pickle.dumps(json.loads(conts))" >file.pickle cat space_sep.dat | pyli "json.dumps(dict(parts))" >file.json
Maybe it makes sense to separate commands:
cat index.html | pyli "for l in [a.get('href') for a in bs4.BeautifulSoup(cs).find_all('a')]: print l" | pyli --text='something' "r = requests.get(li); li if text in r.text else None" cat index.html | pyli "hashlib.sha1(cs).hexdigest()" | pyli "encryptedfile.EncryptedFile(stdout, getpass.getpass()).write(cs)"
Perhaps you want to keep it a one liner, but Python is too opinionated to let you do that:
pyli -f "`ls -a`" "for l in f.split('\n'):" " if '.git' == l: print 'git'"
Do note that you should only access one of these special variables at a time: no work has been put into combining these into something that makes sense, so if you want multiple variables, you’ll have to do the legwork yourself.
