Meant as a simple elisp interpreter with Doom's CLI framework preloaded. Can be used as a shebang line: #!/usr/bin/env doomscript (princ "hello world!") This isn't used for bin/doom because it requires doomscript be in your $PATH, and any attempt to resolve its location in bin/doom's shebang line would reduce its portability. Neither of these should be an issue for the type of user who'd find this useful.

# This is a shebang interpreter for launching emacs lisp scripts with Doom's CLI
|
|
# framework preloaded and all the metadata it needs initialized. Use it like so:
|
|
#
|
|
# #!/usr/bin/env doomscript
|
|
# (print! "Hello world!")
|
|
#
|
|
# For this to work, this file must be in your $PATH.
|
|
#
|
|
# export PATH="$HOME/.emacs.d/bin:$PATH"
|
|
#
|
|
# This can also be exploited to evaluate arbitrary elisp against Doom's CLI
|
|
# environment.
|
|
#
|
|
# This isn't used for bin/doom because of the $PATH requirement (and using
|
|
# $BASH_SOURCE to locate it would reduce its POSIX compliance). This shouldn't
|
|
# be an issue for folks writing their own CLIs, however.
