I am a linux user through and through. Desktop, server, vms, containers, everything except my phone is linux. With this I spend a lot of time in the terminal, and have been a long time user of !! to rerun the last command, but with the ability to tack something on at the beginning or end.

TIL about fc, which opens the last command in your shell history in your $EDITOR or pass in your editor -e nvim.

man fc

Rcap of how !! works #

!! pronounces bang bang and will run the last command in your history.

ls -l

!! | wc -l
# ls -l | wc -l

sudo !!
# sudo ls -l | wc -l

!!:s/-l/-l \/tmp
# sudo ls -l /tmp | wc -l

fc enters the chat #

Now making complex edits in your shell can be a bit of a chore, so fc moves this work to your $EDITOR.

fc

This pops open your $EDITOR with the last command in your history.

sudo ls -l | wc -l

Shell History #

fc shows up in shell history, but !! does not, !! gets replaced by the command that it becomes.

Up Arrow #

yaya yaya, I know you can also up-arrow c-e, but what fun is that, it’s barely a flex. fc just looks big brained and like you really know what you are doing.

I’ve been a long user of pygments, it’s been the thing that injects <spans> with funny little class names like sc and si into the code blocks of my website. I’ve even gone as far as implementing a plugin for md-it, but I had no idea how to re-style it. I long ago got a theme that looked good enough from somewhere and just used it, maybe I pulled something from their docs site and forgot. Today I learned you can list all the themes easily from the library itself, and render out new css.

from pygments.styles import get_all_styles
list(get_all_styles())
# [
#     'abap',
#     'algol_nu',
#     'algol',
#     'arduino',
#     'autumn',
#     'borland',
#     'bw',
#     'colorful',
#     'default',
#     'dracula',
#     'emacs',
#     'friendly_grayscale',
#     'friendly',
#     'fruity',
#     'github-dark',
#     'gruvbox-dark',
#     'gruvbox-light',
#     'igor',
#     'inkpot',
#     'lightbulb',
#     'lilypond',
#     'lovelace',
#     'manni',
#     'material',
#     'monokai',
#     'murphy',
#     'native',
#     'nord-darker',
#     'nord',
#     'one-dark',
#     'paraiso-dark',
#     'paraiso-light',
#     'pastie',
#     'perldoc',
#     'rainbow_dash',
#     'rrt',
#     'sas',
#     'solarized-dark',
#     'solarized-light',
#     'staroffice',
#     'stata-dark',
#     'stata-light',
#     'stata',
#     'tango',
#     'trac',
#     'vim',
#     'vs',
#     'xcode',
#     'zenburn'
# ]

from pygments.formatters import HtmlFormatter
from pygments.styles import get_style_by_name
style = get_style_by_name("monokai")
formatter = HtmlFormatter(style=style)
print(formatter.get_style_defs('.highlight'))

And now you get styles that you can add to your css and be any theme from the list above.
