My zshrc contains the following:

setopt autocd
function cd () {
if (( ${#argv} == 1 )) && [[ -f ${1} ]]; then
[[ ! -e ${1:h} ]] && return 1
builtin cd ${1:h}
else
builtin cd "$@"
fi
}
alias ...='../..'
alias ....='../../..'
alias .....='../../../..'

This allows things like `cd /etc/fstab` to go to `/etc`, `...` to go 2 directories up and `/blah/fasel` to go to `/bla/fasel` without explicit `cd`.

I am basically lost on machines without that. 😿

Знайшов ще одну не погану C++ бібліотеку для розбору вхідних аргументів програми. Називається TCLAP (Templatized C++ Command Line Parser). Вона є header-only тому зібрати набагато простіше, але мені таке не дуже подобається. Подивитись більше інформації з прикладами можна тут. Поширюється бібліотека під ліцензією MIT.

На жаль стандартне форматування помилок, довідки й версії не дуже звичне, але досить просто можна замінити на своє власне. Також було б непогано додати сучасні constexpr і таким чином пришвидшити виконання. А якщо у C++26 нарешті зʼявиться рефлексія. А з використанням C++23 можна було б замінити динамічний поліморфізм на статичний (CRTP). Ну це я вже дуже розмріявся.

Some days you don’t get your own stuff done, but you do point out to someone else that they have loaded a high-caliber #footgun.

#Sanitize your input, folks, and jealously guard your #argc and #argv.
