add add_theme() to save a themes non-default rcParams to themes/theme_name.txt #9

Closed znstrider closed 3 years ago

znstrider commented 3 years ago

This PR adds the function add_theme() to theme.py to save a themes rcParams that differ from the matplotlib default rcParams to themes/theme_name.txt locally.

To do this, this PR also adds the function set_updated_rcparams to theme.py. It iters through the current rcParams, compares them to the default values, and stores the non-default values in theme.updated_params.

This allows us to easily save, share and reuse themes.

I hope this matches the intention you had for this function in the ToDo list, but feel free to correct me if I misunderstood this. On second thought I wonder whether those functions would better belong in set_theme?

theme = themepy.Theme()

# set a theme with
# theme.set_theme(theme_name)
# set rcParams with
# theme.set_pips().set_spines() etc.
# or with
# mpl.rcParams[param] = value

# When happy with the theme, save it for future use.
theme.add_theme(theme_name)

An example of a saved theme by calling add_theme() looks like this:
