# Neophyte

[![Crates.io Version](https://img.shields.io/crates/v/neophyte)](https://crates.io/crates/neophyte)

Neophyte is a Neovim GUI rendered with WebGPU and written in Rust.
It offers several niceties over the default terminal-based UI:

- Text shaping and rasterization by [Swash](https://github.com/dfrg/swash),
providing high-quality font rendering features such as ligatures, fallback
fonts, and emoji
- Smooth scrolling
- Cursor animations
- Pixel-level window positioning

## Installation

Neophyte currently works best on MacOS and Linux. It also requires a compatible
graphics driver, namely Vulkan, Metal, or DX12. Linux targets require the
`fontconfig` library. Installing from Crates.io or Git requires the [Rust
toolchain](https://www.rust-lang.org/tools/install).

### Crates.io

```bash
cargo install neophyte
```

### Git

```bash
git clone https://github.com/tim-harding/neophyte
cd neophyte
cargo build --release
```

The binary will be `target/release/neophyte`.

### Releases

Prebuilt binaries are available in the
[releases](https://github.com/tim-harding/neophyte/releases/latest).

### Packages

#### AUR

##### `neophyte`

Builds from source hosted on Crates.io.

```bash
yay -S neophyte
```

##### `neophyte-git`

Builds from the latest tagged release on GitHub.

```bash
yay -S neophyte-git
```

##### `neophyte-bin`

Installs the latest binary release artifacts from GitHub.

```bash
yay -S neophyte-bin
```

## Cursor animation

For best results, run Neophyte with the `--messages` flag unless you are using
[Noice](https://github.com/folke/noice.nvim) or choose not to enable cursor
animation. This option delegates commandline and
message rendering to Neophyte, which fixes an issue with the cursor jumping
around the screen during search naviation or in response to messages.

## Configuration

Neophyte is scriptable with Lua. The API is LuaLS type-annotated for
discoverability.

```lua
-- lazy.nvim example:
{
'tim-harding/neophyte',
tag = '0.3.0',
event = 'VeryLazy',
opts = {
-- Same as neophyte.setup({ ... })
},
}

-- API usage example:
local neophyte = require('neophyte')
neophyte.setup({
fonts = {
{
name = 'Cascadia Code PL',
features = {
{
name = 'calt',
value = 1,
},
-- Shorthand to set a feature to 1
'ss01',
'ss02',
},
},
-- Fallback fonts
{
name = 'Monaspace Argon Var',
-- Variable font axes
variations = {
{
name = 'slnt',
value = -11,
},
},
},
-- Shorthand for no features or variations
'Symbols Nerd Font',
'Noto Color Emoji',
},
font_size = {
kind = 'width', -- 'width' | 'height'
size = 10,
},
-- Multipliers of the base animation speed.
-- To disable animations, set these to large values like 1000.
cursor_speed = 2,
scroll_speed = 2,
-- Increase or decrease the distance from the baseline for underlines.
underline_offset = 1,
-- For transparent window effects, use this to set the default background color.
-- This is because most colorschemes in transparent mode unset the background,
-- which normally defaults to the terminal background, but we don't have that here.
-- You must also pass --transparent as a command-line argument to see the effect.
-- Channel values are in the range 0-255.
bg_override = {
r = 48,
g = 52,
b = 70,
a = 128,
},
})

-- Alternatively, the guifont option is supported:
vim.opt.guifont = 'Cascadia Code PL:w10, Symbols Nerd Font, Noto Color Emoji'

-- There are also freestanding functions to set these options as desired:

-- Increase font size
vim.keymap.set('n', '', function()
neophyte.set_font_width(neophyte.get_font_width() + 1)
end)

-- Decrease font size
vim.keymap.set('n', '', function()
neophyte.set_font_width(neophyte.get_font_width() - 1)
end)

-- Use cmd-ctrl-f to toggle fullsreen on MacOS
if this_os:find('Darwin') then
vim.keymap.set('n', '', function()
neophyte.set_fullscreen(not neophyte.get_fullscreen())
end)
end

-- Neophyte can also record frames to a PNG sequence.
-- You can convert to a video with ffmpeg:
--
-- ffmpeg -framerate 60 -pattern_type glob -i '/my/frames/location/*.png'
-- -pix_fmt yuv420p -c:v libx264 -vf
-- "colorspace=all=bt709:iprimaries=bt709:itrc=srgb:ispace=bt709:range=tv:irange=pc"
-- -color_range 1 -colorspace 1 -color_primaries 1 -crf 23 -y /my/output/video.mp4
neophyte.start_render('/directory/to/output/frames/')
neophyte.end_render()
```
