From 07fd325b721559525e20d6056408bedc28ec3fc5 Mon Sep 17 00:00:00 2001 From: Arctic Ice Studio Date: Sat, 29 May 2021 00:24:26 +0200 Subject: [PATCH] Conceal highlighting group support (#261) The `Conceal` group was not supported which could have led to rendering problems for (Unicode) characters that require special encoding like the ones from the Greek alphabet [1] that are often used in LaTeX [3] or Pandoc [4] documents. These characters were highlighted with the default background color which makes them kind of unreadable with the theme foreground color. See `:help conceal` and `:help concealcursor` for more details about concealing in Vim. To fix the problem, the `Conceal` group has been added with its background color set to `NONE` for GUI and terminal mode to either use the terminal default background color or let loaded scripts apply custom styles based on the current runtime context. The problem has been reported in GH-149, GH-207 and GH-211 with LaTeX and Pandoc being used by the reporters. PR GH-220 adds support for vim-pandoc/vim-pandoc-syntax [5] specific highlighting groups and can be merged after adding basic support for `Conceal`.
