A blazing-fast, bare-metal Markdown compilation engine and text viewer built entirely inside the terminal. No Electron. No Chromium bloat. Zero browser engine overhead.
mux processes text streams via a low-latency, single-pass memory scanner and renders visual structures instantly in a modern terminal framework—consuming less than 10MB of RAM at runtime.
- Pure C++26 Architecture: Written using cutting-edge C++ Named Modules (
import std;), eliminating legacy macro headers and drastically isolating dependencies. - Instantaneous Evaluation Engine: A custom AST token pipeline parses text buffers character-by-character as you type.
- Dual-View UI Router: Interactive fullscreen tab routing allows developers to swap between focused editing and visual output instantly without keyboard conflicts.
- Bare-Metal Resource Efficiency: Yields a 98%+ reduction in memory and disk footprint compared to classic web-hybrid editors.
-
Ctrl + T: Toggle screen views instantly (Editor Mode$\longleftrightarrow$ Fullscreen Preview Mode). -
Ctrl + S: Intercepts layout focus to open a dynamic filename input prompt for committing buffers directly to disk. -
Ctrl + Q: Force-exits application event loops and cleans terminal screen registers safely. -
Ctrl + F: Find/Replace
mux bypasses heavy, bloated build system tools like CMake. You can compile the full modular dependency tree directly from your shell layout using a recent GCC (14/15/16+) or Clang compiler toolchain.
Because GCC doesn't ship pre-compiled system binaries for modules out of the box, generate your system's std.gcm cache folder exactly once:
g++ -std=c++26 -fmodules-ts -c /usr/include/c++/16.1.1/bits/std.cc# Compile core lexical parsing token engine
g++ -std=c++26 -fmodules-ts -c MuxParser.cppm -o build/MuxParser.o
# Compile high-performance interface workspace module
g++ -std=c++26 -fmodules-ts -c TerminalWorkspace.cppm -o build/TerminalWorkspace.o $(pkg-config --cflags ftxui)g++ -std=c++26 -fmodules-ts main.cpp build/MuxParser.o build/TerminalWorkspace.o $(pkg-config --libs ftxui) -o build/Mux./build/MuxMux/
