Potentially Useful Attributes in PowerShell

UsefulAttributes.md

PowerShell, as a language, is very self-discoverable.

When you Get-Command, you get a rich object about a command.

This can have a lot of metadata.

You can and should also use inline help (like this script does).

Sometimes, I want more metadata than the command or parameter can actually provide.

Each command or parameter can have N attributes (like [CmdletBinding] or [Parameter])

Only a small number are used by PowerShell. The rest are ignored.

Other ones can be used to form special handshakes with command information (such as a friendly name to display in the UI).

While you can Add-Type/use classes to add your own custom attributes, this would require the author of an arbitrary PowerShell script to have imported your module first.

As such, this file has a single function with all of the useful attributes I've run into so far.

Some of these attributes have been used within tools:

Tool	Attribute
Eventful	[Diagnostics.Tracing.EventSource]
Piecemeal	[ComponentModel.Inheritance] [Management.Automation.Cmdlet] [Runtime.CompilerServices.Extension]

.Synopsis
    A Collection of Useful Attributes
.Description
    A collection / proof of concept of useful attributes that exist in both PowerShell and PowerShell Core, out of the box.

    This function outputs useful attributes. It's comments shed light on how these attributes might be used.
.Notes
    PowerShell, as a language, is very self-discoverable.

    When you Get-Command, you get a rich object about a command.

    This can have _a lot_ of metadata.

    You can and should also use inline help (like this script does).

    Sometimes, I want _more_ metadata than the command or parameter can actually provide.

    Each command or parameter can have N attributes (like [CmdletBinding] or [Parameter])

    Only a small number are used by PowerShell.  The rest are ignored.

    Other ones can be used to form special handshakes with command information
    (such as a friendly name to display in the UI).

    While you can Add-Type/use classes to add your own custom attributes, this would require 
    the author of an arbitrary PowerShell script to have imported your module first.

    As such, this file has a single function with all of the useful attributes I've run into so far.

# Can be used for display names/friendlynames (duh)
[ComponentModel.DisplayName('DisplayName')] 
# Can be used to categorize        
[ComponentModel.Category('A Category')]
# Can also be used to categorize     
[ComponentModel.DesignerCategory('A Category')]     
# Can also be used for longer descriptions
[data.datasysdescription("A Description")]  

# Can be used for arbitrary named metadata!!!!!!!!!!! (basically anything)
[Reflection.AssemblyMetadata('key','value')]
# Unfortunately, it will store a ScriptBlock as a string.  Great for syntax highlighting.
[Reflection.AssemblyMetadata('Scriptkey',{"scriptvalue"})]
# Help keywords!  If anyone ever wanted to build a better help browser for PowerShell....
[ComponentModel.Design.HelpKeyword("keyword")]
# Private filtering handshakes?  
[ComponentModel.ToolboxItemFilter("filter")]
# Highlighting?  Databinding?  Not quite sure.    
[ComponentModel.ToolboxItem('itemname')]
# Can be used to indicate type conversion / next step of the pipeline.
[ComponentModel.TypeConverter('foobar')] 
# This is a more obvious databinding property.
[ComponentModel.DefaultBindingProperty("key")]
# This could be quite interesting indeed.
# ValidateScript is nice and useful, but it's not server side.
# This could be useful for describing server-side conditions
# It could also be used as a direct shorthand for the types of values to accept, 
# for instance, allowing ValueFromPipeline to accept all objects but using this attribute to formalize how you skip input.
[Diagnostics.ConditionalAttribute("condition=value")]
# Probably for fun, though it could be used to signal "minify me"
[Reflection.ObfuscationAttribute()]
# Can be used to indicate being the source of an event.
# Used in [Eventful](https://github.com/StartAutomating/Eventful) to indicate the name of an outputted event.
[Diagnostics.Tracing.EventSourceAttribute(Name="NameOfEvent")]
# Can be used to declare a contract with a value.
[Diagnostics.Contracts.ContractOption("Category","Setting","value")]
# While used in C# to identify a cmdlet, this is ignored on a function.  Thus it can be used to indicate relationships between cmdlets.
# In [Piecemeal](https://github.com/StartAutomating/Piecemeal)] this is used to identify the commands a given extension applies to (when used on a script/function).
[Management.Automation.Cmdlet("Get","Something")]
# Can be used to indicate that it is an extension.
# Optionally used in [Piecemeal](https://github.com/StartAutomating/Piecemeal)]

    # Could be used to indicate if the parameter can be changed.  A given command would have to respect this.
    [ComponentModel.ImmutableObject($false)]

    # An example of where this might be useful would be having a cmdlet where most some parameters are mutually exclusive.
    [ComponentModel.MergableProperty($true)]      
    # Can be used to indicate the default underlying properties that this would bind to.
    # (of course, ValueFromPipelineByPropertyName + Aliases will do this just fine)
    [ComponentModel.DefaultBindingProperty("foo")]
    # DefaultValue could be used to indicate a default in a way that is more discoverable.
    # Additionally, since DefaultValue stores an actual object, a ScriptBlock can be directly embedded without being reprocessed.
    [ComponentModel.DefaultValue({"bar"})]
    # AmbientValue could be used to indicate an ambient value (a value related to the state of other values)
    # Additionally, since AmbientValue stores an actual object, a ScriptBlock can be directly embedded without being reprocessed.
    [ComponentModel.AmbientValue({"bar"})]
    # LookupBinding could be very interesting, since lookup binding attributes give us a value could be loaded from a datastore.
    [ComponentModel.LookupBindingProperties("datasource","displayMember","valueMember","lookupMember")]
    # Can be used to a relationship between this parameter and another cmdlet.
    # Used in [Piecemeal 0.1.4+](https://github.com/StartAutomating/Piecemeal) to indicate that a parameter should only apply when used as an extension for a particular command.
