enzu.ru .emacs.d

This .emacs.d represents my libre attempt to build and document a maximalist Emacs configuration utilizing most (but not all) of the latest trends in the Emacs community, tailored of course to my personal taste and needs. This involves around 200 different packages.

This means spicy choices like:

• eglot over lsp-mode
• vert&co over helm and ivy
• corfu over company
• elpaca over package.el and straight.el
• flymake over flycheck (what a comeback!)
• meow over evil
• lispy over paredit
• sly over slime
• prism over rainbow-delimiters and rainbow-blocks
• eat over all the other terminal emulators
• gptel over the dozens of other LLM clients

When I was starting off with Emacs, other people's customizations were deeply helpful for me as a starting point; some of those customizations still find a home in my Emacs instance today. In the spirit of free software, I hope that I can pass on the good will.

Requirements

This config makes extensive use of language servers and tree-sitter grammars. Most of my best supported languages will try to load a language server or tree-sitter grammar. If it fails to, it will warn you and give you a chance to install what is missing.

I usually only support one version of Emacs at a time. Currently I am supporting:

• Emacs 29
• Emacs 30

Features

Operating systems

The following operating systems are supported:

• FreeBSD
• GNU/Linux
• macOS
• OpenBSD
• Windows

Additionally, this entire .emacs.d can be setup with native compilation, all necessary development environments below, and as your window manager by visiting my profiles repo, which can be executed on the Guix GNU/Linux distribution.

Development environments

This Emacs configuration reflects my REPL-centered exploratory programming style.

I provide an IDE and REPL for each major environment that I work in.

One can debate about which languages Emacs is actually ideal for, but Emacs is certainly a best-in-class environment for Haskell, Elixir, Common Lisp, Scheme, and Clojure.

First class

The best supported developer environments are the Lisp languages. Since they have feature rich IDEs with powerful REPLs, they do not need Eglot.

Language	IDE	REPL	Eglot
Clojure	CIDER	CIDER	N/A
Common Lisp	SLY	SLY	N/A
Scheme	Geiser	Geiser	N/A

Second class

Guix comes with pre-packaged language servers for these languages.

Language	IDE	REPL	Eglot
C	c-ts-mode		Yes
C++	c++-ts-mode		Yes
Go	go-ts-mode	go-playground	Yes
Python	Anaconda	run-python	Yes
Ruby	Robe	inf-ruby	Yes
Rust	Racer	rust-playground	Yes

Third class

Guix lacks pre-packaged language servers for these languages.

Language	IDE	REPL	Eglot
Elixir	Alchemist	inf-elixir	No
Fish	fish-mode	fish-completion	No
Haskell	Intero	Dante	No
JavaScript	js2-mode	Indium	No
PHP	php-mode	PsySH	No
SQL	sql-mode	emacsql	No
TypeScript	Tide	Indium	No

Fourth class

I don't even have a REPL for these languages, and quite frankly, most of these languages are best used within their respective IDEs.

Language	IDE	REPL	Eglot
GDScript	gdscript-mode		Yes
Groovy	groovy-mode		No
Java	java-ts-mode		No
Kotlin	kotlin-mode		No
Objective-C	objc-mode		No
Swift	swift-mode		No

Tools

This configuration ships with a great many helpful tools:

Feature	Tool
Benchmarker	elisp-benchmarks
Bug tracker	debbugs
Clipboard	Clipetty
Completion (regular buffer)	Corfu
Completion (minibuffer)	Vert&co

Themes

There are many beautiful theme families for you to enjoy:

• arjen-grey
• deep-thought
• dracula
• exotica
• gotham
• molokai
• omtose-phellack
• purple-haze
• sanityinc-tomorrow
• timu-caribbean
• timu-macos
• timu-rouge
• timu-spacegrey
• zenburn

Keystrokes

This is a modal editing setup that uses two different modal editors: Meow and Lispy. Lispy is only for Lisp languages.

I maintain the default Emacs keybindings, so I will not document them here. Meow will help you discover keystrokes after you hit SPC in keypad mode.

Normal editing

Run meow-tutor to learn Meow.

Meow documentation

Lisp editing

Lispy editing is activated only in major modes for Lisp languages when around parens in Meow's insert mode.

• e evaluate s-expression
• f forward point through parens
• b undo
• ] move point down
• [ move point up
• > slurp up next s-expression
• < barf up s-expression
• w move s-expression up
• s move s-expression down
• r raise s-expression
• C-1 view documentation
• C-2 view caller arguments

Lispy documentation

Movement between buffers

Movement between buffers is accomplished with windmove:

• Shift-up
• Shift-left
• Shift-right
• Shift-down

Tab management

I have keystrokes setup to emulate tmux/screen using Emacs tabs.

• C-z(one) c(reates) a new workspace.
• C-z(one) k(ills) a current workspace.
• C-z(one) n(ext) workspace.
• C-z(one) p(revious) workspace.

Custom keystrokes

These are custom keystrokes that I have setup.

When in Meow's insert mode, prepend with C-c. When in Meow's keypad mode, prepend with SPC.

• a(g) search git repo using ag
• b(uffer) switch buffers with autocompletion
• i(sp) search through Lisp symbols (defaults to Emacs Lisp)
• d(ocumentation) brings up documentation for symbol under cursor
• e(at) brings up the Eat terminal
• k(ill) kill buffer unconditionally
• l(ocate) locate a file
• o(mpile) compiles the buffer in a language appropriate way
• p(ush) pushes the current git branch
• r(eplace string) replace all occurrences of a string after point
• s(tatus) shows the current git status
• t(abs) search through tabs
• y(ank) show list of yanked items
• <left> previous buffer
• <right> next buffer
• <up> beginning of buffer
• <bottom> bottom of buffer

Learning

Everything is very organized in the enzuru folder by feature, mode, preference, setup, operating system, and theme. While this repo should work immediately for you on a git pull, it's obviously a very personalized setup and many things won't appeal to you. If I were you, I would first take a look at my init.el and then pick a topical elisp file from there.

Happy hacking!
