Compilation of common functions that shell script developers find themselves writing again and again in their daily basis. Sort of standard library for the shell but well, not so standard I guess. Proven to work with Bash and Zsh.
Disclaimer: This project is mainly an investment in my future self and is not intented for production use. That said, the automated tests and shell checks ensure a minimum of quality.
Use the bundle utility to extract the functions required into a single chunk:
bin/bundle prompt::yesnoStandard output:

prompt::yesno() {
local text="$1"
local default="yes"
if (( $# > 1 )); then
default=$2
fi
local p="$(style::green ${PROMPT_SYMBOL}) $(style::bold ${text}) "
echo -n "$p"
if is_yes $default; then
echo -n "$(style::dim \(Y/n\)) "
else
echo -n "$(style::dim \(y/N\)) "
fi
read output
is_yes $output || (str::is_empty "$output" && is_yes $default)
}
style::green() {
# missing function
}
style::dim() {
# missing function
}
str::is_empty() {
[[ -z "$1" ]]
}
