all keyword

The all keyword is a powerful way to accomplish several useful scenarios with a very natural syntax.

all can get all of a set of things that match a criteria and run one or more post-conditions.

EXAMPLE 1

& {
$glitters = @{glitters=$true}
all that glitters
}.Transpile()

EXAMPLE 2

function mallard([switch]$Quack) { $Quack }
Get-Command mallard | Get-Member  | Select-Object -ExpandProperty TypeName -Unique
all functions that quack are ducks
Get-Command mallard | Get-Member  | Select-Object -ExpandProperty TypeName -Unique

EXAMPLE 3

. {
    $numbers = 1..100
    $null = all $numbers where { ($_ % 2) -eq 1 } are odd
    $null = all $numbers where { ($_ % 2) -eq 0 } are even
}.Transpile()
@(
    . { all even $numbers }.Transpile()
).Length

@(
    . { all odd $numbers }.Transpile()
).Length

The input to be searched.

If set, include all functions in the input.

If set, include all commands in the input.

If set, include all cmdlets in the input

If set, include all aliases in the input

If set, include all applications in the input

If set, include all applications in the input

If set, include all variables in the inputObject.

If set, will include all of the variables, aliases, functions, and scripts in the current directory.

A condition. If the condition is a ScriptBlock, it will act similar to Where-Object. If the condition is not a script block, the conditional will be inferred by the word choice. For example:

all functions matching PipeScript

will return all functions that match the pattern 'PipeScript' Or:

all in 1..100 greater than 50

will return all numbers in 1..100 that are greater than 50. Often, these conditionals will be checked against multiple targets. For example:

all cmdlets that ID

Will check all cmdlets to see if:

• they are named "ID"
• OR they have members named "ID"
• OR they have parameters named "ID"
• OR their PSTypenames contains "ID"

An action that will be run on every returned item. As with the -Where parameter, the word choice used for For can be impactful. In most circumstances, passing a [ScriptBlock] will work similarly to a foreach statment. When "Should" is present within the word choice, it attach that script as an expectation that can be checked later.

The way to sort data before it is outputted.

If output should be sorted in descending order.

The Command AST. This parameter and parameter set are present so that this command can be transpiled from source, and are unlikely to be used.

All [[-InputObject] <Object>] [-Functions] [-Commands] [-Cmdlets] [-Aliases] [-Applications] [-Scripts] [-Variables] [-Things] [[-Where] <Object>] [[-For] <Object>] [[-Sort] <Object>] [-Descending] -CommandAst <CommandAst> [<CommonParameters>]
