# Builds a sandbox for Emacs (and optionally, Doom) with a particular version of
# Emacs. Use this as a basis for module shell.nix's.
#
# Usage examples:
#
# To create a doom environment with the test config:
#
# nix-shell
#
# With your own DOOMDIR:
#
# nix-shell --argstr doomdir ~/.config/other-doom-config
#
# With a specific version of Emacs
#
# nix-shell --argstr emacs 26.3 # 26.3
# nix-shell --argstr emacs 27.1 # 27.1
# nix-shell --argstr emacs 27.2 # 27.2
# nix-shell --argstr emacs 28.1 # 28.1
# nix-shell --argstr emacs 28.2 # 28.2
# nix-shell --argstr emacs 29.1 # 29.1
# nix-shell --argstr emacs head # 30.0.50
# nix-shell --argstr emacs ci-26.3 # 26.3 (barebones; no GUI)
# nix-shell --argstr emacs ci-27.1 # 27.1 (barebones; no GUI)
# nix-shell --argstr emacs ci-27.2 # 27.2 (barebones; no GUI)
# nix-shell --argstr emacs ci-28.1 # 28.1 (barebones; no GUI)
# nix-shell --argstr emacs ci-28.2 # 28.2 (barebones; no GUI)
# nix-shell --argstr emacs ci-29.1 # 29.1 (barebones; no GUI)
# nix-shell --argstr emacs ci-HEAD # 30.0.50 (barebones; no GUI)
