uterm

uterm is a WIP terminal emulator, written in C++11 using Skia, libtsm, and GLFW.

Supported platforms

Currently uterm has only been tested on Linux, though it should also work on OSX. It may also work on BSD; anyone willing to test it should be able to just edit fbuildroot.py to change all instances of {'linux'} to {'linux', 'bsd'}.

Downloading

AppImages are available here. If you want to build it yourself, read on.

Dependencies

GLFW.
OpenGL and EGL. These should come by default with your Linux mesa installation.
Freetype2 and Fontconfig.

Building

You need Fbuild version 0.3 RC 2 or greater. (Just using the master branch should be good enough.) Run:

$ fbuild

to do a full build. If you want to do a release build, instead use:

$ fbuild --release

Note that the initial build will take quite a while, as it will be building the entire Skia library, which is pretty huge.

If you're concerned about size, a debug build is 73MB, and a release build is only 6MB (largely thanks to LTO).

Configuration

Configuration is done using libConfuse. Here's an example config file (stored in $HOME/.config/uterm/uterm.conf)

// C-style comments are supported

// ***VERTICAL SYNC***
// By default, uterm uses adaptive vsync, which is given via a vsync value of -1. If you
// experience input lag, try setting it to 0. On the other hand, if you experience screen
// tearing, you can try setting it to 1, but it might cause input delays. -1 should make
// sure input is snappy while still avoiding tearing.
vsync = -1

// ***FONTS**

// Set the default font size.
font-defaults {
  size = 16
}

// By default uterm uses the system monospace font. Any fonts appearing here will
// take priority in the order that they are specified in this file.

// These can specify a size too if you want; it'll look just like above.

// In this example, Roboto Mono is the #1 font. If any characters aren't available
// in Roboto Mono, it'll fall back to Hack. After that, it will fall back to the system
// monospace font.
font "Roboto Mono" {}
font Hack {}

// ***THEMING***

theme test {
  // You can use 0xRRGGBB style
  red = 0xFF0000
  // or 0xRRGGBBAA style
  background = 0xFFFFFFAA

  // Supported colors: black, red, green, yellow, blue, magenta, cyan, white
  // Prefix a color with bright_ (e.g. red_bright) to set the "bright" version of the color.
  // You can also set the default foreground and background color:

  foreground = 0x000000

  // If any of the mentioned colors are ommitted, they will use the versions from the default
  // theme.
}

// You can define multiple themes in this file. To switch between them, use current-theme:
current-theme = test

// If you omit it to set it to an empty string (""), the default theme will be used.
