CLI-ize ME
It is what the name means!

Writing A CLI program
● It is not difficult with a library. (ex. argparse)
● But it is annoying,
especially for the simple tasks.
3

At one midnight ...
I was thinking about the schema of the database.
● initdb.py ● db.py init
● cleardb.py ● db.py clear
● dropdb.py ● db.py drop
... ...

I opened the doc of argparse,
argparse,
5

then felt sleepy …
6

It shouldn't be long!
# file: db.py
def init():
pass
def clear():
pass
def drop():
pass
if __name__ == '__main__':
import sys
locals()[sys.argv[1]]()

But human wants are unlimited!

After hardworking,

Clime was released.

It converts your program
# file: pyramid.py
def draw(story, squash=1):
ground_len = 1 + (story-1) * squash * 2
for i in range(1, ground_len+1, squash*2):
print ('*'*i).center(ground_len)
11

into a CLI program
$ python pyramid.py --help
usage: [--squash] <story>
or: draw [--squash] <story>
$ python pyramid.py –-squash=5 3
*

just by adding this line:

It also supported aliases
…
def draw(story, squash=1):
'''It draws a pyramid.
-s, --squash It is optional.
'''
…
16

and metavars.
…
def draw(story, squash=1):
'''It draws a pyramid.
-s <int>, --squash=<int>
'''
…
17

It is also an executable module.
$ python -m clime math
usage: acos <x>
or: acosh <x>
