#+TITLE: ui/pretty-code
#+DATE: June 16, 2018
#+SINCE: v2.0.9
#+STARTUP: inlineimages nofold
* Table of Contents :TOC_3:noexport:
- [[#description][Description]]
- [[#maintainers][Maintainers]]
- [[#module-flags][Module Flags]]
- [[#plugins][Plugins]]
- [[#prerequisites][Prerequisites]]

* Description
This module enables ligatures and/or arbitrary symbol substitutions with
~prettify-symbols-mode~.
** Maintainers
This module has no dedicated maintainers.
** Module Flags
+ =+fira= Enables =Fira Code= ligatures. This requires Fira Code Symbol and a
patched version of Fira Code (see below).
+ =+hasklig= Enable =Hasklig= ligatures. This requires a patched version of the
HaskLig font (see below).
+ =+iosevka= Enable =Iosevka= ligatures. This requires a patched version of the
Iosevka font (see below).
+ =+pragmata-pro= Enable =Pragmata Pro= ligatures. This requires the [[https://www.fsd.it/shop/fonts/pragmatapro/][Pragmata
Pro font]].
** Plugins
This module installs no packages.
* Prerequisites
For ligatures to work, you must:
1. Enable one of the four ligature font flags: =+fira=, =+hasklig=, =+iosevka=
or =+pragmata-pro=.
2. Install the patched version of the associated font with ~M-x
+pretty-code/install-patched-font~. Note: Pragmata Pro cannot be installed
this way because it isn't a non-free font and must be purchased and installed
manually.
* TODO Features
# An in-depth list of features, how to use them, and their dependencies.
* TODO Configuration
# How to configure this module, including common problems and how to address them.
** TODO ~set-pretty-symbols!~
* TODO Troubleshooting
# Common issues and their solution, or places to look for help.
