;;; poet-theme.el --- A theme for prose

;; Copyright 2018-now Kunal Bhalla

;; Author: Kunal Bhalla <bhalla.kunal@gmail.com>
;; URL: https://github.com/kunalb/poet/
;; Version: 2.1
;; Package-Requires: ((emacs "24.1"))
;; Keywords: faces, theme, prose

;;; Commentary:

;; An emacs theme that's well suited for prose: particularly org-mode and 
;; markdown-mode; or any mode that works well with `variable-pitch` mode.

;; Emacs has very good support for multiple fonts in a single
;; file.  Poet uses this support to make it much more convenient to
;; write prose within Emacs, with particular attention paid to
;; org-mode and markdown-mode.  Code blocks, tables, etc are
;; formatted in monospace text with the appropriate backgrounds.

;; Theme Customizations
;; - `poet-theme-variable-headers`
;;    Enable / disable different text heights for different faces.
;; - `poet-theme-variable-pitch-multiplier`
;;    Relative size for the variable pitch font; modify for a better visual
;;    balance.

;; NOTE: poet-variable-headers was renamed to poet-theme-variable-headers.

;; Recommended customizations for using this theme
;;
;; - Set up the base fonts you'd like to use in Emacs before loading Poet
;;     (set-face-attribute 'default nil :family "Iosevka" :height 130)
;;     (set-face-attribute 'fixed-pitch nil :family "Iosevka")
;;     (set-face-attribute 'variable-pitch nil :family "Baskerville")
;;   On loading this theme captures the default and treats that for fixed-pitch
;;   rendering.
;;
;; - Enable variable pitch mode for editing text
;;     (add-hook 'text-mode-hook
;;                (lambda ()
;;                 (variable-pitch-mode 1))

;; This file was generated by tangling metapoet.org, included with the theme.
