#!/usr/bin/env bash
# Dotfile management script in the vein of [[https://github.com/anishathalye/dotbot][dotbot]] and [[https://github.com/bashdot/bashdot][bashdot]].
#
# This script is designed to replace [[https://github.com/mohkale/dotty][dotty]] and acts a single file that's
# to be sourced and by some management script that can subsequently install
# your dotfiles. I migrated from my initial lispy dotfile manager to this
# script because I don't always have the freedom to download an external
# program but any unix environment should have a bash like shell available.
#
# Dependencies: bash>=4, readlink
# Environment variables:
# + root: Path to the root of your dotfiles repository.
# Notes:
# + Installation scripts should avoid prompting the user or writing to
# stdout unless explicitly required. Some executions of this script
# may not have an interactive stdin or terminal stdout.
# shellcheck disable=SC2317
set -a # Export everything

# This directive is a little more involved than the others because
# it requires some extra flexibility. For each call to it the first
# argument is the package manager to use and the rest are arguments
# to that package manager. If the package manager doesn't exist the
# command fails and you can branch to another package manager. If
# called with no packages this directive just checks whether that
# package manager is available. You can use this to create a branching
# installer directive such as:
# package yay foo bar ||
# package pacman foo bar ||
# error 'No package manager found, skipping'
#
# This first tries installing with yay, then with pacman and if both
# those don't exist then it outputs and error message and continues.
