Cooking up some beautiful text

The core goal of linecook is to make it easy to create your own transforms to parse whatever text you have. For example, take an app.log file that looks like:

If you want to highlight the log type and mute the dates/times, then you can create a custom recipe in one of your configuration files like the following:

from linecook import patterns as rx
from linecook.transforms import color_text

LINECOOK_CONFIG = {
    'recipes': {
        'my-logs': [
             color_text(rx.any_of(rx.date, rx.time), color='blue'),
             color_text('INFO', color='cyan'),
             color_text('WARN', color='grey', on_color='on_yellow'),
             color_text('ERROR', on_color='on_red'),
        ],
    },
}

To use this recipe, you can just pipe the log output to linecook with your new recipe as an argument:

That’s all there is to it!
