# 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/doom
|
|
#
|
|
# With a specific version of Emacs
|
|
#
|
|
# nix-shell --arg emacs 26 # 26.3
|
|
# nix-shell --arg emacs 27 # 27.1
|
|
# nix-shell --arg emacs 28 # HEAD
