Font
Doom exposes five (optional) variables for controlling fonts in Doom. Here are the three important ones:
doom-fontdoom-variable-pitch-fontdoom-big-font– used fordoom-big-font-mode; use this for presentations or streaming.
They all accept either a font-spec, font string (Input Mono-12), or xlfd font
string. You generally only need these two:
(setq doom-font (font-spec :family "Fira Mono Medium" :size 12))Theme
A list of all doom themes can be found here:
https://github.com/hlissner/emacs-doom-themes
(setq doom-theme 'doom-one)Line numbers
Possible values of display-line-numbers-type are nil, t, and 'relative.
(setq display-line-numbers-type 'relative)Programming
LSP
Doom disables documentation display in child frames by default; I like those, so re-enable them, and reset the defaults.
(after! lsp-ui
(setq lsp-ui-doc-max-width 150)
(setq lsp-ui-doc-max-height 30)
(setq lsp-ui-doc-enable t))Rust
By default rustic-mode uses rls, I want to use rust-analyzer instead.
(setq rustic-lsp-server 'rust-analyzer)I don't want to enable format-on-save globally in Doom, but having it in rust is nice.
(after! rustic
(setq rustic-format-trigger 'on-save))C/C++
Setup the default format for C/C++ editing.
(setq c-default-style "gnu")
(setq c-basic-offset 2)Flycheck never works well for C / C++ without configuration or a CMake build system. Let's disable it.
(after! flycheck
(setq flycheck-global-modes '(not c-mode c++-mode)))Org mode
Doom replaces the default tab behavior on headings, this restores the default one. Taken from here.
(after! evil-org
(remove-hook 'org-tab-first-hook #'+org-cycle-only-current-subtree-h))Doom indents subtitles and their content by default, I prefer to leave them as is.
(after! org
(setq org-startup-indented nil))
