  https://github.com/hocestnonsatis/sherion/releases/latest/download/sherion-installer.sh | sh

Windows (PowerShell)

powershell

irm https://github.com/hocestnonsatis/sherion/releases/latest/download/sherion-installer.ps1 | iex

Windows (MSI) — download sherion-x86_64-pc-windows-msvc.msi from Releases.

macOS (Homebrew)

bash

brew install hocestnonsatis/tap/sherion

Requires the hocestnonsatis/homebrew-tap repository and HOMEBREW_TAP_TOKEN secret on the main repo for automated formula updates.

Linux (.deb)

Download sherion_*_amd64.deb from Releases, then:

bash

sudo dpkg -i sherion_*_amd64.deb

Linux (.rpm)

Download sherion-*.rpm from Releases, then:

bash

sudo dnf install ./sherion-*.rpm

Linux (Flatpak)

Download sherion-x86_64.flatpak from Releases, then:

bash

flatpak install --user sherion-x86_64.flatpak

Linux (AppImage)

Download Sherion-x86_64.AppImage from Releases, make it executable, and run:

bash

chmod +x Sherion-x86_64.AppImage
./Sherion-x86_64.AppImage

Quick start

bash

sherion

Enable debug logging:

bash

RUST_LOG=sherion=debug sherion

Use a profile:

bash

sherion --profile dark

Configuration

Sherion reads config from (in order):

SHERION_CONFIG environment variable
~/.config/sherion/sherion.toml (or $XDG_CONFIG_HOME/sherion/sherion.toml)
./sherion.toml in the current directory (legacy fallback)

Copy or edit sherion.toml as a starting point. See SECURITY.md for hardening guidance.

bash

SHERION_CONFIG=/path/to/sherion.toml sherion

Key sections: [font], [colors], [terminal], [appearance], [ui], [keybindings], [profiles.*].

Build from source

Requirements

Rust 1.88+
GPU with Vulkan, Metal, DX12, or a compatible wgpu backend
A monospace font (DejaVu Sans Mono, Liberation Mono, or Noto Sans Mono)

bash

git clone https://github.com/hocestnonsatis/sherion.git
cd sherion
cargo build --release
./target/release/sherion

Optional SIMD UTF-8 acceleration:

bash

cargo build --release --features simd-utf8

Stack

Layer	Crate
Window + events	winit 0.30
GPU	wgpu 29
Terminal core (grid, VTE, PTY)	alacritty_terminal 0.26
Text shaping	parley 0.10
GPU rendering	vello 0.9
Config	serde + toml

Architecture

PTY I/O runs on a dedicated alacritty_terminal event-loop thread, isolated from the UI. The winit main thread shapes text with parley, builds vello scenes, and presents frames through wgpu with dirty-row damage tracking.
