			So I want to get a single character. https://github.com/max1220/lua-getch should work but it doesn't work on mac I guess. Probably read its source code (c) and port it

			Ok so rather than jump right into the fennel environment, I can start by making my editor in lua and then add fennel scripting support. Then eventually rewrite the editor in fennel other than a short bootstrap ... if I want ... lua ain't that bad. But it's harder to evaluate interactively due to its lack of explicit parens () !

			The first thing for my editor to do is respond to keys being pressed. Like a c getch(). So forgetting about file IO for a moment, my "editor" is going to start looking like a command line, but each key press is handled by the program and printed individually - one at a time style. When you hit (? some key that is like quit)

			(could be c-q for now)

			it'll exit the program and say "you entered x bytes. Saving to (datetime).txt" - something like that.

			Well I found the error was in the .so:

			<pre>
			>> (pcall require :readline)
			false "error loading module 'C-readline' from file '/usr/local/lib/lua/5.4/C-readline.so':
			\tdlopen(/usr/local/lib/lua/5.4/C-readline.so, 6): Symbol not found: _rl_callback_sigcleanup
			Referenced from: /usr/local/lib/lua/5.4/C-readline.so
			Expected in: flat namespace
			in /usr/local/lib/lua/5.4/C-readline.so"
			</pre>
			So I tried uninstalling readline to see if it'd remove that file, and it did... and fixed the error o_O
			<pre>
			Fennel $ sudo luarocks remove readline
			Checking stability of dependencies in the absence of

	Let's do a little fennel research		Let's do a little fennel research

			Ok I installed fennel pretty easily with a git clone then `make`. But I got a warning about readline

			So I brew installed readline and heeded the warnings

			<pre>
			==> Caveats
			readline is keg-only, which means it was not symlinked into /usr/local,
			because macOS provides BSD libedit.

			For compilers to find readline you may need to set:
			set -gx LDFLAGS "-L/usr/local/opt/readline/lib"
			set -gx CPPFLAGS "-I/usr/local/opt/readline/include"

			For pkg-config to find readline you may need to set:
			set -gx PKG_CONFIG_PATH "/usr/local/opt/readline/lib/pkgconfig"
			==> Summary
			🍺 /usr/local/Cellar/readline/8.2.13: 51 files, 1.7MB, built in 42 seconds
			</pre>

			Adding the environment variables to my ~/.profile didn't do anything (it even auto sourced so I think it applied fine)

			I tried symlinking but that didn't work either

			<pre>
			Fennel $ symlink /usr/local/opt/readline/include/readline/ /usr/local/include/
			Fennel $ ls /usr/local/include/readline/
			chardefs.h keymaps.h rlconf.h rltypedefs.h
			history.h readline.h rlstdc.h tilde.h

			Then I saw https://github.com/technomancy has some contributions to https://github.com/bakpakin/Fennel

			And neovim supports lua

			So maybe rather than a totally new editor, it's a neovim distribution that is configured only in fennel

			Let's do a little fennel research

New page

Trying to install sci https://github.com/babashka/sci?tab=readme-ov-file to use for a clojure-esque based editor ... oh yeah to get https://github.com/babashka/babashka?tab=readme-ov-file

Anyways

https://clojars.org/org.babashka/sci

Gives

[org.babashka/sci "0.8.43"]

It'd be nice to have a way to "pip install" this kind of dependency. Though I must remember that this is a clojure dependency, not a babashka one etc (so it wouldn't work quite like this in my editor)

Still adding some clojure tooling is nice
