Yet Another CLI framework

TL;DR

Searching for CLI modules on MetaCPAN returns 1690 results. And still I wrote another, Yet Another CLI framework. This is about why mine is the one you want to use.

Introduction

CLI clients, we all write them, we all want them, but the boilerplate is just horrible. I wanted to get rid of it: Burn it with 🔥.

At my previous dayjob we had something I wrote, or co-wrote, my boss wanted a sort of chef like API. It became zsknife, but had a huge downside. You needed to register each command in the main module and I didn’t like that at all. I forked the concept internally, made it so you didn’t needed to register, but it lacked discovery.

Question: How can you configure grub to use a specific kernel?

Answer

You can configure grub via several ways to use a specific kernel or you can configure grub to use the latest one, or you can tell grub to pick one from a selection.

One specific kernel

If you inspect /etc/grub/grub.cfg you’ll see entries like this:

# the \ are mine, these are usually one big line but for blog purposes I
# multi-lined them
menuentry 'Debian GNU/Linux GNU/Linux, with Linux 6.12.8-amd64' --class debian \
    --class gnu-linux --class gnu --class os $menuentry_id_option \
    'gnulinux-6.12.8-amd64-advanced-5522bbcf-dc03-4d36-a3fe-2902be938ed4' {

You can use two identifiers to configure grub; you can use 'Debian GNU/Linux GNU/Linux, with Linux 6.12.8-amd64' or you can use the $menuentry_id_option with gnulinux-6.12.8-amd64-advanced-5522bbcf-dc03-4d36-a3fe-2902be938ed4.

zsh: drop sed for regexp-replace and use zstyle to avoid hardcoding things in a script

Zsh has regexp-replace, you don’t need sed:

autoload regexp-replace
regexp-replace line '^pick' 'f'

Also, instead of hard coding values, use zstyle:

# in your .zshrc
zstyle ':xyz:xyz:terminal' terminal "kitty"

# in your script/function
local myterm
zstyle -s ':xyz:xyz:terminal' terminal myterm || myterm="Eterm"
