Emacs Configuration

An Emacs configuration that assumes:

• Vanilla Emacs as a base. At least version 29.
• Vim-like keybindings via evil-mode while editing code and prose, but normal Emacs keybindings elsewhere to avoid sprawling keymap overrides. Also, a vi-like status line. Should be a reasonable POSIX vi alias replacement for quick edits.
• "Spacebar as leader key" from Spacemacs to reduce modifier key usage. For example, supporting SPC v to split a window vertically, as an alternative to the Vim keybinding C-w v.
• Monospace fonts for code. Variable-width, serif fonts for anything else.
• A preference for built-in packages wherever possible, e.g. project.el rather than Projectile, and eglot rather than lsp-mode.
• Support for disabling all third party packages, for environments which are particularly high-risk in the face of supply chain attacks. viper steps in for evil-mode here.
• Both GUI and terminal support.
• Support both light and dark mode, and respect the host OS's preference.
• Wide OS support, at least Linux, macOS, and Windows. on startup.
• use-package to configure packages.
• An embrace of customize rather than bypassing it.
• Lexically-scoped ELisp that uses more abstract, less concrete APIs. That includes the generic sequence functions over more concrete data structure functions, generalised setters via setf over setq and setcar, equal unless a more specific equality function is necessary, etc.

TODO:

• Better support running as a service, e.g. systemctl enable --now --user emacs.
• Polish the treesitter and LSP integrations more, and enable by default.
• Enable live previews of in-project grepping and file-finding.
• Pinning of third party package commits. Not obviously viable with package.el unless getting packages directly from their VCS source. straight.el could be another approach.
