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

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)"

- 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

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"

- Autocomplete
- Look through modules for 2nd level functions to import

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!
