Reference: Overview Zutty is a fast, lightweight terminal emulator for X Window System, optimized for low-end systems. It uses OpenGL ES 3.1 for rendering, offering high throughput and low latency. Key Features: GPU-accelerated rendering using Compute Shaders Accurate VT emulation (VT52, VT100, VT102, VT220, VT320, VT420, VT520, xterm) Supports bitmap and TrueType fonts, including CJK characters True color support (24-bit) X clipboard/primary selection/copy-paste, including rectangular selection Installation (Debian/Ubuntu) Dependencies: sudo apt-get install build-essential pkg-config python3 libegl-dev libfreetype-dev libgles-dev libxmu-dev Source: git clone https://git.hq.sig7.se/zutty.git cd zutty Configure: ./waf configure Compile: ./waf Install: sudo ./waf install Usage Launching zutty [options] [shell] zutty -e [command] Options Option Description Default -altScroll Alternate scroll mode (arrow keys on alt screen) false -autoCopy Sync primary selection to clipboard false -bg <color> Background color #000 -boldColors Use bright colors for bold text true -border <n> Border width (pixels) 2 -cr <color> Cursor color foreground color -display X display $DISPLAY -dwfont Double-width font 18x18ja -fg <color> Foreground color #fff -font Font name 9x18 -fontsize Font size (scaled fonts) 16 -fontpath Font search path /usr/share/fonts -geometry Terminal size (chars) 80x24 -glinfo Print OpenGL info false -help Print usage   -listres Print resource listing   -login Start shell as login shell false -name Instance name for Xrdb and WM_CLASS Zutty -rv Reverse video false -saveLines Scrollback history (lines) 500 -shell Shell to run bash -showWraps Show wrap marks false -title/-T Window title Zutty -quiet Silence logging false -verbose Verbose logging false -e Command to execute   User Actions Action Trigger Scroll half page Shift+PageUp/Down Scroll 5 lines / 1 line Scroll wheel / (alt screen with -altScroll) Start/Adjust selection Left/Right mouse button press & hold Cycle selection snapping Double-click left/right mouse button Toggle rectangular select Space (while selecting) Paste primary selection Middle mouse button, Shift+Insert Copy selection to clipboard Ctrl+Shift+C Paste clipboard Ctrl+Shift+V Configuration Zutty can be configured via command-line options, X resources, and environment variables. Command-line options override X resources, which override defaults. X Resources Edit ~/.Xresources and add entries like: Zutty.title: My Terminal Zutty.geometry: 100x30 Zutty.font: LiberationMono Zutty.fontsize: 14 Zutty.fg: #eee Zutty.bg: #222 Merge changes: xrdb -merge ~/.Xresources Environment Variables Zutty sets/uses: DISPLAY: X display SHELL: Shell path TERM: xterm-256color COLORTERM: truecolor WINDOWID: X window ID ZUTTY_VERSION: Zutty version RESOURCE_NAME: Instance name for Xrdb (if -name option not used) Development Debug Build ./waf configure --debug ./waf Run: build/src/zutty.dbg -v Step Debugger Activate with PrintScreen key (in debug build). Cycles through step counts (1, 10, 100, off). Resume with kill -CONT <pid> or fg. Testing See the test/ directory for automated tests. Run individual tests (e.g., test/vttest.sh) or all tests with test/run_ci.sh.
