Docs?

@Enovotny
Should decide if we want both developer and enduser docs.

If developer docs do I put those in CONTRIBUTING with the below howto?

If enduser, would you like to see a page in addition to what would present automatically from the site builder made by the args?

i.e. something explaining the colors and when/why you might disable them (file based logs)

PR Details

I started with blob which will dynamically figure out if an object is JSON and format it (screenshot below)

I did have to hook into the logger to try and catch the logs at a low level.

This also made it so you do not have to pass the no-color optione everywhere.

This introduces log-file and log-level arguments.

Where you would call it like this:

cwms-cli --log-level=DEBUG blob list

Right after cwms-cli. Keeping the blob/list arg list from looking like a book.

I have it coloring the log level by default in 4 different colors.

But to explicitly color a log item with JSON you can do this:

import logging
from cwmscli.utils.logging.formatters import format_df_for_log


logging.info(
            format_df_for_log(
                df, c=c, col_colors={0: "BLUE", 1: "GREEN"}, json_color=True
            )
        )

You can also arbitrarily color various parts of text with
c("some text", "BLUE")

or

logging.info(c("hello", "GREEN") + " " + c("world", "BLUE"))
which would give
