The Nihongo Yet Another GOing Shell

<English> / <Japanese>

NYAGOS - Nihongo Yet Another GOing Shell is a versatile command-line shell that blends bash-like command-line editing with seamless integration of Windows file system paths and batch files. It offers extensive customization through the Lua scripting language and supports modern predictive input features.

Key Features

UNIX-Like Shell Behavior

• Keybindings
  • By default, keybindings are similar to Bash.
  • Customizable via Lua scripts in %USERPROFILE%\.nyagos.

    nyagos.key.c_u = "KILL_WHOLE_LINE"
    

  • Lua functions can be bound to keys:

    nyagos.key.f1 = function(this) nyagos.exec("start vim.exe") end
    

• History and Aliases
  • Supports Ctrl-P history search and !-style command recall.
  • Alias system similar to DOSKEY:

    nyagos.alias["g++"] = "g++.exe -std=gnu++17 $*"
    

  • Lua-powered aliases:

    nyagos.alias["lala"] = function(args) nyagos.exec("ls", "-al", unpack(args)) end
    

• Custom Command Completion (Bash-Style Tab Completion)
  • Allows defining completions for specific commands.

    nyagos.complete_for["go"] = function(args)
        if #args == 2 then
            return { "bug", "doc", "fmt", "install", "run", "version",
                     "build", "env", "generate", "list", "test", "vet",
                     "clean", "fix", "get", "mod", "tool" }
        else
            return nil -- file completion
        end
    end
    

• Predictive Completion (PowerShell 7-Like)
  • Suggests completions based on command history.
  • Predictions can be accepted using Ctrl-F or the right arrow key.

Windows Compatibility

• Seamless Batch File Execution
  • Runs Windows batch files (.bat and .cmd) as if executed directly in CMD.exe.
  • Captures environment variable changes and directory switches made within batch files.
• CMD.EXE-Like Features
  • Supports Windows path formats (C:\path\to\file).
  • Maintains a separate current directory for each drive.
  • Includes built-in equivalents for common DOS commands (copy, move, etc.).
  • No additional DLLs required, and no registry modifications.

Enhanced User Experience

• Colorized Command-Line Interface
• Unicode Support
  • Full compatibility with Windows Unicode APIs.
  • Supports pasting and editing of Unicode characters.
  • Special Unicode literals: %U+XXXX% and $Uxxxx for prompts.
• Built-in ls Command
  • Supports colorized output (-o option).
  • Displays hard links, symbolic links, and junction targets.
• Support SKK (Simple Kana Kanji conversion program) - Setup Guide

Supported Platforms

• Windows 7, 8.1, 10, 11, Windows Server 2008 or later
• Linux (experimental)
