Este mini-tutorial es sólomente apto para los amantes de las aplicaciones commandline.
¿Les gusta la imagen de arriba?, ¿Creen que pueden mejorarlo?, entonces me alegro mucho ya que les voy a explicar como pueden hacer lo mismo de forma muy sencilla.
Se me ocurrió la idea de darle un poco de 'vida' a las secciones de ayuda de mis aplicaciones así que ideé un metodo de uso genérico ...y a mi parecer creo que quedó sencillo y eficaz.
Los pasos a seguir son estos:
1. Copien y peguen esta Class que contiene la documentación de ayuda, en su proyecto:
' Name.......: Help Section
' Author.....: Elektro
' Description: Class that manages the Help documentation of a Console application with colorization capabilities.
' Last Update: 05/01/2014
' References.: LINQ, 'WriteColoredText' method by Elektro.
' Indications: Use *F##* as the ForeColor beginning delimiter, use *-F* to restore the console forecolor.
' Use *B##* as the BackColor beginning delimiter, use *-B* to restore the console BackColor.

3. En la sección regionada '
Help Text' deben especificar lo que deseen, el logo, la sintaxis, la información de contacto, etc... eso es lo único que deben hardcodear (óbviamente no va a ser un
click&go, pues toda aplicación tiene distintos parámetros así pues distinta información).
Por ejemplo, inspeccionemos este nodo:
<!-- Application Usage Examples -->
<UsageExamples>
{f11}[+]{-f} {f14}Usage examples{-f}
<%= ProcessName %> /Switch1=Value "C:\File.txt"
{f11}( Command explanation ){-f}
</UsageExamples>
¿Que significan todos esos parámetros 'F'?, bien, son los delimitadores que establecí para indicar el principio y el fínal de un cambio de color (color de texto o color de fondo),
un cambio de color de texto debe empezar con la letra "F" (de
Forecolor), y un cambio de color de fondo debe empezar con la letra "B" (de
BackgroundColor),
seguídamente le añadiremos un número del 0-15 que hace referencia a un color de consola (solo existen 15), por ejemplo: el inicio de cambio de color de texto "{
F11}" hace referencia al color de consola número 11, que es el color '
Cyan'
Para restaurar el color original usaremos el delimitador
{-f} o
{-b} respectívamente del tipo de cambio de color del que se trate.
Y para mostrar el texto coloreado es necesario usar un método que ideé el cual se encarga de parsear los delimitadores de cambio de colores.
Un ejemplo de uso de los método:
Module Module1
Sub Main()
Console.Title = HelpSection.ColorizedHelp.<Title>.Value
Dim sb As New System.Text.StringBuilder
sb.AppendLine(HelpSection.ColorizedHelp.<Logo>.Value)
sb.AppendLine(HelpSection.ColorizedHelp.<Separator>.Value)
sb.AppendLine(HelpSection.ColorizedHelp.<Syntax>.Value)
sb.AppendLine(HelpSection.ColorizedHelp.<UsageExamples>.Value)
WriteColoredTextLine(sb.ToString, {"*"c})
' WriteColoredText(sb.ToString, {"*"c})
Threading.Thread.Sleep(60000)
End Sub
End Module
Además, los métodos son de uso genérico y hay 1 overload para los dos métodos, esto significa que pueden reutilizarlos de forma individual en cualquier otro tipo de proyecto, de la siguiente manera:
WriteColoredText(" Hello World! ", ConsoleColor.Blue, ConsoleColor.Blue)
WriteColoredTextLine(" Hello World! ", ConsoleColor.Magenta, ConsoleColor.Gray)
WriteColoredTextLine(" Hello World! ", Nothing, Nothing)
WriteColoredText("*F10*Hello *F14*World!*-F*", {"*"c})
WriteColoredTextLine("{B15}{F12} Hello World! {-F}{-B}", {"{"c, "}"c})
WriteColoredTextLine(String.Format("*B15**F12* {0} *F0*{1} *-F**-B*", "Hello", "World!"), {"*"c})
Eso es todo, ¿te resultó facil?, espero que este mini-tutorial le haya servido a alguien.
Saludos!
