Emacs Configuration

A fast, modular Emacs IDE setup with ~0.77s startup and full IDE features via LSP.

Features

• IDE: eglot + LSP (C/C++, Go, Python, Rust, JS/TS, Web)
• Lazy Loading: Deferred packages for speed
• Bytecode Compiled: Optimized execution
• Modular: Easy to extend
• Auto-save: Smart save on focus-out/idle

Installation

Requirements: Emacs 27+, Git, language servers

git clone https://github.com/cabins/emacs-config ~/.emacs.d
cd ~/.emacs.d && make compile
emacs

Features

IDE: Go-to definition, find references, completions, diagnostics via eglot Editing: Multiple cursors, move lines, snippets, bracket highlighting UI: Modern modeline, accessible themes, icon support Utilities: Fuzzy search, git integration, buffer management

Performance

Startup: ~0.77s (7945HX Fedora i3, SSD, Emacs 29.3)

Optimizations:

• Deferred garbage collection at startup
• Lazy package loading (packages only load on demand)
• Bytecode compilation for all modules
• Native compilation enabled when Emacs is built with --with-native-compilation
• Package quickstart cache (Emacs 27.1+)

Modules

Module	Purpose
init-fn.el	Utility functions
init-system.el	Platform-specific settings
init-elpa.el	Package manager (MELPA)
init-ui.el	Themes and fonts
init-builtin.el	Emacs built-in features
init-package.el	Third-party packages
init-ide.el	LSP and language servers
init-kbd.el	Keybindings

Compilation

make compile        # Compile everything
make compile-local  # Compile config only
make compile-native  # Compile native code only, if supported
make clean          # Remove all .elc/.eln files

All .elc files are byte-compiled for faster loading. .eln files are generated only when the Emacs binary supports native compilation.

Language Support

Language	Server	Key Bindings
C/C++	clangd	M-. (definition), M-? (references)
Go	gopls	Same
Python	pylsp	C-c p s (sort imports)
Rust	rust-analyzer	Auto-formats on save
JS/TS	typescript-language-server	Same as C/C++
Web	vls (Vue)	HTML/CSS support

All LSP features include: go-to-definition, find references, completions, diagnostics, formatting.

Keybindings

Binding	Function
M-.	Go to definition
M-?	Find references
C-c f	Format buffer
M-<up>/<down>	Move line up/down
C-c d	Mark next occurrence
C-x C-b	Buffer list
C-c v	Git status
C-s	Search

Custom bindings can be added to custom.el.

Troubleshooting

Issue	Cause	Solution
LSP not working	Server not installed	Install language server, run M-x eglot-reconnect
Completions not showing	Company mode off	Run M-x company-mode
Slow startup	Packages not compiled	Run make compile
No .eln files	Emacs lacks native compilation support	Use an Emacs build with --with-native-compilation or rely on .elc only
Stale bytecode	Old .elc files	Run make clean && make compile

See init files for detailed settings.

Customization

• Add packages: Edit lisp/init-package.el
• Change keybindings: Edit lisp/init-kbd.el or add to custom.el
• Override settings: Use custom.el (loaded last, overrides everything)

Example custom.el:

(custom-set-variables '(package-name-variable value))
(global-set-key (kbd "C-c x") 'my-command)

Recompile after changes: make compile
