INTRODUCTION                                                 *edge-introduction*

This color scheme is heavily inspired by Atom One and Material, I'm trying to
combine my favorite designs of them in this color scheme.

Features~

- Vivid colors.
- Designed to have a soft contrast for eye protection.
- Customizable.
- Rich support for common file types and plugins.
- Tree-sitter support.
- Semantic highlighting support.
- Italic support 🎉

==============================================================================
INSTALLATION                                                 *edge-installation*

Note: For better syntax highlighting support, consider installing one of the
following plugins additionally to this colorscheme:

	https://github.com/sheerun/vim-polyglot
	https://github.com/nvim-treesitter/nvim-treesitter.

As a Native Vim Package

Users of Vim 8 and greater may leverage Vim's native |packages| system.

1. Create a new directory: `$ mkdir -p ~/.vim/pack/colors/opt`

2. Clone this repository: `$ git clone --depth 1 https://github.com/sainnhe/edge.git ~/.vim/pack/colors/opt/edge`

3. Generate help tags: `:helptags ~/.vim/pack/colors/opt/edge/doc/`

4. Add `packadd! edge` to your vimrc.

Note: If you install this color scheme to `pack/*/start` instead of
`pack/*/opt`, you still need to add `packadd! edge` to your vimrc,
as discussed in the following issue:
https://github.com/sainnhe/gruvbox-material/issues/60

------------------------------------------------------------------------------
Manually

Dim inactive windows. Only works in Neovim currently.

When this option is used in conjunction with |g:edge_show_eob| set to 0, the
end of the buffer will only be hidden inside the active window. Inside
inactive windows, the end of buffer filler characters will be visible in
dimmed symbols. This is due to the way Vim and Neovim handle |hl-EndOfBuffer|.

g:edge_spell_foreground~

By default, this color scheme won't color the foreground of |spell|, instead
colored under curls will be used. If you also want to color the foreground,

    Available values:   `'none'`, `'colored'`
    Default value:      `'none'`

g:edge_better_performance~

The loading time of this color scheme is very long because too many file types
and plugins are optimized. This feature allows you to load part of the code on
demand by placing them in the `after/syntax` directory.

Enabling this option will reduce loading time by approximately 50%.

    Type:               |Number|

------------------------------------------------------------------------------

The colors don't match those in the screenshots.~

1. This color scheme is mainly designed for true colors, `set termguicolors`
is required. Check output of `vim --version`, maybe your vim doesn't support
`termguicolors`.

2. Maybe your terminal emulator doesn't support true colors, you can test it
using [this script](https://unix.stackexchange.com/questions/404414/print-true-color-24-bit-test-pattern).

3. If you are running vim in tmux, you need to override default true colors of
tmux, as tmux cannot display true colors properly:
[#1246 How to use true colors in vim under tmux?](https://github.com/tmux/tmux/issues/1246)

------------------------------------------------------------------------------

The configuration options don't work.~

You should place them before `colorscheme edge` .

------------------------------------------------------------------------------

A lot of errors are detected if I install with pack feature.~

You'll need to add `packadd! edge` before applying this color scheme.
Check [sainnhe/gruvbox-material#60](https://github.com/sainnhe/gruvbox-material/issues/60)

------------------------------------------------------------------------------

How to enable cursive italic keywords?~

1. Install a font that supports cursive italics, for example https://aka.sainnhe.dev/fonts

2. Enable italic keywords in this color scheme: `let g:edge_enable_italic = 1`

3. (Optional) Disable italic comment: `let g:edge_disable_italic_comment = 1`

------------------------------------------------------------------------------

The comment color looks weird.~

Some terminal emulators don't support italics, which may cause the comment
color looks weird. See https://github.com/sainnhe/gruvbox-material/issues/5#issuecomment-729586348

A temporary solution is to disable italic comments via
|g:edge_disable_italic_comment|.

If you are using tmux, you may also need to override default true colors of
tmux: https://github.com/tmux/tmux/issues/1246
