Better python CLI integration
Project description
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.
Examples
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) 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
Maybe it makes sense to separate commands:
cat index.html | pyli "a.get('href') for a in bs4.BeautifulSoup(cs).find_all('a')" | 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)"
pyli
Features:
Automatically import referred packages
Populate special CLI oriented variables
line (li, l)
lines (lis, ls)
contents (cont, cs)
stdin, stdout, stderr
Accept arbitrary GNU style arguments (-c, –blah), and make them available
Print last statement; if an assignment, print the assigned to variables
If we are using line, then print the last statement for each line
pylie
So your perl one-liner itch hasn’t been itched enough yet? This command is for things that do not strictly fit into ‘normal’ python usage. For example:
log | pyli "'{0} {1}'.fo(s(ti.ti()), l)" cat index.html | pyli "a.g('href') for a in BeSp(cs).f_all('a')" | pyli --text='something' "r = req.get(li); li if text in r.text else None"
Features:
Autocomplete
Look through modules for 2nd level functions to import
TODO
What’s left to do? Well, pretty much everything: it currently imports things and prints things out, and detects the use of contents/input/conts, but that’s it. If you think this would be actually useful, do send me a message, since I just ran out of motivation with which to work on this. Or better yet, contribute!
