¿Cómo puedo hacer que aparezcan los mensajes de ayuda para mis parámetros de script de Powershell?
Tengo un script de powershell (setup.ps1
), que usamos como punto de entrada para nuestros scripts de configuración del entorno de desarrollo. Toma un parámetro:
param(
[Parameter(Position=0,HelpMessage="The targets to run.")]
[Alias("t")]
[string[]]
$Targets = "Help"
)
Cuando corro
PS > get-help .\setup.ps1 -detailed
En la sección parámetros, mi mensaje de ayuda no aparece:
PARAMETERS
-Targets <String[]>
¿Qué debo hacer para que se muestren mis mensajes de ayuda de parámetros?

Coloque un cierto estilo de comentario en la parte superior del archivo que puede decodificar el sistema de ayuda de PowerShell. He aquí un ejemplo:
<#
.SYNOPSIS
.
.DESCRIPTION
.
.PARAMETER Path
The path to the .
.PARAMETER LiteralPath
Specifies a path to one or more locations. Unlike Path, the value of
LiteralPath is used exactly as it is typed. No characters are interpreted
as wildcards. If the path includes escape characters, enclose it in single
quotation marks. Single quotation marks tell Windows PowerShell not to
interpret any characters as escape sequences.

Al parecer, si tiene un encabezado de ayuda definido, solo puede usar un comentario ( # ) detrás del parámetro (en este ejemplo: #Los objetivos a correr.):
