Support command-line options

[livibetter]

Continued from #3.

PyClock has some in-clock options, it might be a good idea to parse options -- and configuration file in future if desired. Using standard argparse is enough for the task.

In response to https://github.com/Regaerd/PyClock/pull/3#issuecomment-175990325 The rearrangement was mostly for https://github.com/Regaerd/PyClock/issues/7, but since that's fixed, it's not a high priority.

Also, I really like the idea of a config file.

8 is a blocker of this issue.

I will finish this after #8, then see what we can do with a configuration file, discussing format / locations. At that time, we can add setup.py for PyPI, and so on. Version 1.0.0 is not far away and PyClock will be displayed on every Unix-like system, totally clockomination.

PyPI would be excellent.

@Regaerd I got a naming question while writing the option descriptions, --width and --height will be confusing to users. Since I have read enough of PyClock code, I know what the width and height actually mean.

Segment width? [Character] Point/Dot width (How could point has width)? These ain't going to work. Character base width?

Any ideas?

By the way, I want to turn center display on by default, would you agree on this?

Here is a sample of help message:

usage: pyclock.py [-h] [-S] [-C] [-c] [-a] [--color {0,1,2,3,4,5,6,7,8,9}]
                  [-W WIDTH] [-H HEIGHT]

A digital clock for the terminal

optional arguments:
  -h, --help            show this help message and exit
  -S, --no-seconds      do not display seconds
  -C, --no-colons       do not display colons
  -c, --center          center clock display
  -a, --auto-scale      turn on auto scale display
  --color {0,1,2,3,4,5,6,7,8,9}
                        color 0-9 (defauilt: 2)
  -W WIDTH, --width WIDTH
                        width (default: 1)
  -H HEIGHT, --height HEIGHT
                        height (default: 1)

Anything needs to reword, or?

--width and --height will be confusing to users

I was just thinking this as well when I was looking over the source. Since they're used to scale segments, might scale width and scale height be better?

I'm fine with this. On that note, any arguments against having autoscale on by default as well?

That's really nice. I have nothing to add.

[...] Since they're used to scale segments, might scale width and scale height be better?

They are much better terms, I will use them.

I forgot that, I will turn it on by default as well.

Closing this, this was done by #9.
