#!/usr/bin/env sh

# WHY: test -z "${DOROTHY_LOADED-}"

#

# sometimes bash_profile and bashrc are loaded on new terminals

# sometimes bash_profile is loaded at login, and bashrc is loaded on new terminals

# sometimes bash_profile will remember and export variables, but not functions

# zsh loads zprofile, and zshrc, but forgets functions

#

# As such, we need a way that will prevent double loads, but prevent inheritance.

# As functions in bash are sometimes forgotten, and functions in zsh are forgotten,

# that rules out https://stackoverflow.com/a/14467452 for this purpose.

# And as exported variables will be inherited by subshells, that rules out exported variables.

# As such, checking for the existence of a non-global non-local variable will work for this case.

# Note that bash v3 does not support `test ! -v 'DOROTHY_LOADED'`, so have to use `test -z "${DOROTHY_LOADED-}"``

# WHY: "$0" != 'bash'

#

# Sometimes, non-login shell invocations will attempt to load this script:

# - `bash -c -- 'echo $BASH_VERSION'`

# - `zsh -c -- 'echo $BASH_VERSION'`

#

# Whereas only true login shells should, as well as manual login shell invocations:

# - `bash -lc -- 'echo $BASH_VERSION'`

# - `zsh -lc -- 'echo $BASH_VERSION'`

#

# As such, we need to detect this difference, here are the samples:

#

# A true bash login shell (v3):

# - `$0` is `-bash`

# - `$-` is `himBH` via this script and manully, or if v5 then `himBHs` manually

# - `shopt -qp login_shell` returns `0`

#

# Manual invocation `bash -il` (v5):

# - `$0` is `bash`

# - `$-` is `himBH` via this script, then `himBHs` manually

# - `shopt -qp login_shell` returns `0`

#

# Manual invocation `/bin/bash -il` (v3) and `/usr/local/bin/bash -il` (v5):

# - `$0` is bash location: `/bin/bash`

# - `$-` is "himBH" via this script and manually

# - `shopt -qp login_shell` returns `0`

#

# A true zsh login shell:

# - `$0` is `-zsh`

# - `$-` is `569XZilm` via this script, then `569XZilms` manually

# - `[[ -o login ]]` returns `0`

#

# Manual invocation of zsh login shell via `/bin/zsh -il`:

# - `$0` is current script then zsh location

# - `$-` is `569XZilm` via this script, then `569XZilms` manually

# - `[[ -o login ]]` returns `0`

#

# Manual invocation of zsh non-login shell via `/bin/zsh -i`:

# - `$0` is current script then zsh location

# - `$-` is `569XZim` via this script, then `569XZims` manually

# - `[[ -o login ]]` returns `0`
