Wez's Terminal
A terminal emulator implemented in Rust, using OpenGL ES 2 for rendering.
Quickstart
- Install
rustup
to get the nightlyrust
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
ortarget/release/wezterm
You will need a collection of support libraries; important to note is that
your harfbuzz
library must have support for hb_ft_font_create_referenced
;
older linux distributions don't have this!
$ sudo apt-get install -y libxcb-icccm4-dev libxcb-ewmh-dev \
libxcb-image0-dev libxcb-keysyms1-dev libharfbuzz-dev \
libfontconfig1-dev libfreetype6-dev libegl1-mesa-dev
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
- Paste selection via Shift-Insert (bracketed paste is supported!)
- SGR style mouse reporting (works in vim and tmux)
- xterm style selection of text with mouse
- Render underline, italic, bold, strikethrough
- Configuration file to specify fonts and colors (in progress)
- Command line argument parsing instead of launching user shell
- Hyperlinks see: https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda
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
- Sixel / iTerm2 graphics protocol support
- Tabs
- Textual renderer. Think
tmux
orscreen
. - Runs on Linux with Wayland (use XWayland for now)
- Runs on Windows
Configuration
wezterm
will look for a TOML configuration file in $HOME/.config/wezterm/wezterm.toml
,
and then in $HOME/.wezterm.toml
.
Configuration is currently very simple and the format is considered unstable and subject
to change. The code for configuration can be found in src/config.rs
.
I use the following in my ~/.wezterm.toml
:
font_size = 10
font = { fontconfig_pattern = "Operator Mono SSm Lig Medium" }
# How many lines of scrollback to retain
scrollback_lines = 3500
[[font_rules]]
italic = true
font = { fontconfig_pattern = "Operator Mono SSm Lig Medium:style=Italic" }
[[font_rules]]
italic = true
intensity = "Bold"
font = { fontconfig_pattern = "Operator Mono SSm Lig:style=Italic:weight=bold" }
[[font_rules]]
intensity = "Bold"
[font_rules.font]
fontconfig_pattern= "Operator Mono SSm:weight=bold"
# if you liked xterm's `boldColor` setting, this is how you do it in wezterm,
# but you can apply it to any set of matching attributes!
foreground = "tomato"
[[font_rules]]
intensity = "Half"
font = { fontconfig_pattern = "Operator Mono SSm Lig Light" }
The default configuration will attempt to use whichever font is returned from
fontconfig when monospace
is requested.
Colors
You can configure colors with a section like this. In addition to specifying
SVG/CSS3 color names, you can use #RRGGBB
to specify a color code using the
usual hex notation; eg: #000000
is equivalent to black
:
[colors]
foreground = "silver"
background = "black"
cursor = "springgreen"
ansi = ["black", "maroon", "green", "olive", "navy", "purple", "teal", "silver"]
brights = ["grey", "red", "lime", "yellow", "blue", "fuchsia", "aqua", "white"]
