Cmder is a portable console emulator for Windows, built on top of ConEmu and enhanced with clink (command-line editing), Git integration, and a custom prompt. It provides a unified shell experience across cmd.exe, PowerShell, and bash, with features like tab management, aliases, and a lambda-shaped prompt. The launcher (Cmder.exe) manages ConEmu configuration files, sets environment variables (CMDER_ROOT), and handles context menu registration. When a shell starts, it sources initialization scripts (init.bat for cmd, profile.ps1 for PowerShell, cmder.sh for bash) that configure PATH, aliases, Git awareness, and prompt styling. The project bundles vendored dependencies (ConEmu, clink, git-for-windows, clink-completions) and includes build scripts for packaging releases. Its architecture is a collection of shell init scripts orchestrated by a lightweight C++ launcher, with no persistent services or daemons.
