A custom Lisp reader written in Elisp. This makes it possible to define syntax
extensions, similar to what can be done in Common Lisp with
Once loaded, this library will kick in when loading other
.el files, when
evaluating expressions in a buffer via
C-M-x or via
M-x eval-region or when
running commands in the REPL (
M-x ielm) etc. If there are bugs, they will
most probably render your Emacs session unusable.
It's recommended to byte-compile it before loading, otherwise it's quite slow:
emacs --batch --eval '(byte-compile-file "elisp-reader.el")'
This isn't a final product. It's rather a request for brainstorming. It proves that it's possible to implement file-local symbols or a better syntax for RegExp-s; a customizable reader in general—by just doing everything in Lisp rather than in C.
