ReadLine

ReadLine is a GNU Readline like library built in pure C#. It can serve as a drop in replacement for the inbuilt Console.ReadLine() and brings along
with it some of the terminal goodness you get from unix shells, like command history navigation and tab auto completion.

It is cross platform and runs anywhere .NET is supported, targeting netstandard1.3 means that it can be used with .NET Core as well as the full .NET Framework.

Installation

Available on NuGet

Visual Studio:

PM> Install-Package ReadLine

.NET Core CLI:

dotnet add package ReadLine

Usage

Read input from the console

string input = ReadLine.Read("(prompt)> ");

Read password from the console

string password = ReadLine.ReadPassword("(prompt)> ");

Note: The (prompt>) is optional

History management

// Get command history
ReadLine.GetHistory();

// Add command to history
ReadLine.AddHistory("dotnet run");

// Clear history
ReadLine.ClearHistory();

// Disable history
ReadLine.HistoryEnabled = false;

Note: History information is persisted for an entire application session. Also, calls to ReadLine.Read() automatically adds the console input to history

Auto-Completion

class AutoCompletionHandler : IAutoCompleteHandler
{
    // characters to start completion from
    public char[] Separators { get; set; } = new char[] { ' ', '.', '/' };

    // text - The current text entered in the console
    // index - The index of the terminal cursor within {text}
    public string[] GetSuggestions(string text, int index)
    {
        if (text.StartsWith("git "))
            return new string[] { "init", "clone", "pull", "push" };
        else
            return null;
    }
}

ReadLine.AutoCompletionHandler = new AutoCompletionHandler();

Note: If no "AutoCompletionHandler" is set, tab autocompletion will be disabled
