Termino

A very simple but cool looking, customizable and interactive text UI for your console tools.

Installation

dotnet add package Termino

Interface interaction

You only need 3 keys to interact with it: Up, Down, Enter. Use the Up and Down arrow keys to navigate through options, then press Enter to select an option.

Customization

If you are not satisfied with the default theme you can tweak it's options using the Termino.Models.Themes.TerminoTheme class.

Some of the customization options are:

• Colors (for title, options, currently selected option)
• Top margin
• Left margin
• Options indicator character
• Display/Hide cursor
• Loop navigation between options

Code Examples

Print and interact with a menu

// Create an instance of TerminoUI
var terminoUI = new TerminoUI();

// Print a menu to the user
terminoUI.PrintMenu(TerminoMenu.Create("Choose an action", "Action 1", "Action 2", "Action 3"));

// Process the user selected option
var actionAnswer = terminoUI.ReadUserInput().Name;
switch (actionAnswer)
{
    case "Action 1":
        // TODO: Execute action 1
        break;

    case "Action 2":
        // TODO: Execute action 2
        break;
}

Change default theme options

// Create an instance of TerminoUI
var terminoUI = new TerminoUI();

// Declare a theme with custom options
var theme = new TerminoTheme
{
    TitleForegroundColor = ConsoleColor.DarkYellow
};

// Set the theme
terminoUI.SetTheme(theme);

// Print a menu to the user
terminoUI.PrintMenu(TerminoMenu.Create("Choose an action", "Action 1", "Action 2", "Action 3"));

// Process the user selected option
var actionAnswer = terminoUI.ReadUserInput().Name;
switch (actionAnswer)
{
    case "Action 1":
        // TODO: Execute action 1
        break;

    case "Action 2":
        // TODO: Execute action 2
        break;
}

Termino.Logging

• Integrates Termino with with Microsoft.Extensions.Logging.
• Supports structured logging.

Installation

dotnet add package Termino.Logging

Code Examples

Setup and use Termino and Termino.Logging in apps that use Host builder

var builder = Host.CreateApplicationBuilder(args);

// Add TerminoUI and Termino.Logging to the DI container
builder.Services.AddLogging(config =>
{
    config.AddTerminoLogging();
    config.SetMinimumLevel(builder.Configuration.GetValue<LogLevel>("MinimumLogLevel"));
});

var host = builder.Build();

// Manually get a new instace of Termino UI.
// Note: You can also inject it into your services
using var serviceScope = host.Services.CreateScope();
var terminoUI = serviceScope.ServiceProvider.GetRequiredService<TerminoUI>();

// Print a menu to the user
terminoUI.PrintMenu(TerminoMenu.Create("Choose an action", "Action 1", "Action 2", "Action 3"));

// Process the user selected option
var actionAnswer = terminoUI.ReadUserInput().Name;
switch (actionAnswer)
{
    case "Action 1":
        // TODO: Execute action 1
        break;

    case "Action 2":
        // TODO: Execute action 2
        break;
}

// Get from DI an ILogger<T> in your services (e.g. via dependency injection)
private readonly ILogger<MyService> _logger;

public MyService(ILogger<MyService> logger)
{
    _logger = logger;
}

// Log messages in TerminoUI
_logger.LogInformation("Hello {@name}.", name);
