Wez's Terminal

A terminal emulator implemented in Rust.

Quickstart

• Install rustup to get the nightly rust compiler installed on your system. https://www.rust-lang.org/en-US/install.html
• Build in release mode: cargo build --release
• Run it via either cargo run --release or target/release/wezterm

You will need a collection of support libraries; I built this incrementally so far so I don't have a complete list. Please open an issue if you work through and discover the full and proper list of packages for ubuntu:

• xcb and xcb-util development packages
• fontconfig
• harfbuzz
• freetype

What?

Here's what I'm shooting for:

• A terminal escape sequence parser
• A model of a terminal screen + scrollback that is OS independent
• Textual and GUI rendering of the model
• A differential protocol for the model

This would manifest as a common core that could run as both a textual terminal multiplexer and a gui terminal emulator, where the GUI part could automatically provide a native UI around the remotely multiplexed terminal session.

Status / Features

These are in the done/doing soon category:

• Runs on Linux with XCB
• Scrollback (use mouse wheel and Shift Page{Up|Down})
• True Color support
• Color Emoji and font fallback (Note: currently assumes you have the Operator font!)
• Paste selection via Shift-Insert
• xterm style selection of text with mouse
• Configuration file to specify fonts and colors
• Render underline, italic, bold, strikethrough
• Command line argument parsing / launching of user shell (currently runs only zsh!)

There's a good number of terminal escape sequences that are not yet implemented and that will get fleshed out as the applications I use uncover them. Similarly for key mappings.

Things that I'd like to see happen and that have no immediate priority (contributions to get closer to these are welcomed!)

• Runs on macOS
• Tabs
• Textual renderer. Think tmux or screen.
• Runs on Windows
