結構大事。
PowerShell V3.0でのやり方ですね。
Finding Built-In Variables
簡単に見ておきます。
変数の取得
現在の変数の取得には、コマンドレットが用意されています。
Get-Variable
あるいは、[PSDrive]のVariableで一覧取得もありですね。
Get-ChildItem variable:
ただ、これでは、ビルトイン変数とユーザー定義変数がごっちゃ混ぜになってしまいます。
Get-Variable | select *や
Get-ChildItem variable:では区別がつかないのでしょうか？
つかないのです…。
例えば$aを定義します。
$a = 0
Built-In変数と見比べてみてください。
Get-Variable | select * | sort Name
#あるいは
Get-ChildItem variable: | select * | sort Name
どうでしょうか。
PSPath : Microsoft.PowerShell.Core\Variable::a
PSDrive : Variable
PSProvider : Microsoft.PowerShell.Core\Variable
PSIsContainer : False
Name : a
Description :
Value : 0
Visibility : Public
Module :
ModuleName :
Options : None
Attributes : {}
PSPath : Microsoft.PowerShell.Core\Variable::?
PSDrive : Variable
PSProvider : Microsoft.PowerShell.Core\Variable
PSIsContainer : False
Value : True
Name : ?
Description : 最後のコマンドの実行状態。
Visibility : Public
Module :

Options : ReadOnly, AllScope
Attributes : {}
PSPath : Microsoft.PowerShell.Core\Variable::^
PSDrive : Variable
PSProvider : Microsoft.PowerShell.Core\Variable
PSIsContainer : False

Description :

Options : None
Attributes : {}
PSPath : Microsoft.PowerShell.Core\Variable::ConsoleFileName

Description : 現在のコンソール ファイルの名前。

そこで、今回の記事の内容が生きてきます。
ビルトイン変数のみを取得したい
ここに格納されています。
[psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static')
ただそのまま出してしまうと…ちょっと。

型一覧の取得
まず、型を見てみましょう。
[psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') `
| sort FieldType -Unique `
| select FieldType
System.Collections.Generic.List`1[System.String]
System.Management.Automation.VariablePath
System.String
System.String[]
System.Type[]
型毎に変数の取得
型ごとの変数を見てみると…
$fieldType = $specialVariables `
| sort FieldType -Unique
$fieldType `
| %{
$type = $_
$specialVariables `
| ?{$_.FieldType -eq (iex ("[" +$_.FieldType +"]"))} `
| %{[PsCustomObject]@{userpath=$_.GetValue($null); type=$type}} `
| sort userpath -Unique
}
ちょっと出力がはみ出たので、調整しています。
$fieldType = $specialVariables `
| sort FieldType -Unique
$fieldType `
| %{
$type = $_
$specialVariables `
| ?{$_.FieldType -eq (iex ("[" +$_.FieldType +"]"))} `
| %{[PsCustomObject]@{
userpath=$_.GetValue($null)
type=$type.ToString().Substring(0,18)}} `
| sort userpath -Unique
}
userpath type

[string]型がビルトイン変数
ということで、[System.String]に該当するuserpathがビルトイン変数のようです。
それなら話は簡単で、コレで
[psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') `
| Where-Object {$_.FieldType -eq ([string])} `
| ForEach-Object {$_.GetValue($null)}
PowerShell 3.0では、{}を省略可能になったので…

ユーザー定義変数だけ抽出したい
ここまでくれば、ユーザー定義変数だけを出すこともできますね。
まず、このままではビルトイン変数に足りないものがありますので洗い出します。
PowerShellを一度閉じてユーザー定義変数をクリアにした状態で実行します。
$builtinVariable = [psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') | Where-Object FieldType -eq ([string]) | ForEach-Object GetValue $null
$other = Get-Variable | ?{$_.Name -notin $builtinVariable}
$other.Name
一覧です。
builtinVariable
FormatEnumerationLimit
MaximumAliasCount
MaximumDriveCount
MaximumErrorCount
MaximumFunctionCount
MaximumVariableCount
profile
psISE
PSSessionOption
一番上のbuildinVariableを除く、これらを足してあげましょう。
$other | where {$_.Name -ne "builtinVariable"} | ForEach-Object {$builtinVariable += $_.Name.ToString()}
[05/March/2013改定]
上記は、起動直後しか有効になりません。
実際は、以下のハードコード対応が必要です。
$other = , @(
"FormatEnumerationLimit",
"MaximumAliasCount",
"MaximumDriveCount",
"MaximumErrorCount",
"MaximumFunctionCount",
"MaximumVariableCount",
"PGHome",
"PGSE",
"PGUICulture",
"PGVersionTable",
"PROFILE",
"PSSessionOption"
)
$other `
| ForEach-Object {$builtinVariable += $_}
で出力と。
$builtinVariable
キッチリ増えてますね。

ここまでくれば、ユーザー定義変数との照合も簡単です。
Get-Variableのすべての変数出力と、$builtInVariableを照合するだけです。
Get-Variable `
| Where {$_.Name -notin $builtinVariable} `
| select Name, Value, Description
ユーザー定義変数取得Function
[05/March/2013改定]
ではFunction化してみます。
function Get-UserVariables{
param(
)
$builtinVariable = [psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') `
| Where-Object FieldType -eq ([string]) `
| ForEach-Object GetValue $null
$other = , @(

"PROFILE",
"PSSessionOption"
)
$other `
| ForEach-Object {$builtinVariable += $_}
Get-Variable `
| Where {$_.Name -notin $builtinVariable} `
| select Name, Value, Description
}
実行は、一文だけです。
Get-UserVariables | Format-List
Functionで利用した変数だけですね！
Name : builtinVariable
Value : {MaximumHistoryCount, MyInvocation, OFS, OutputEncoding...}
Description :

Value : {FormatEnumerationLimit MaximumAliasCount MaximumDriveCount MaximumErrorCount MaximumFunctionCount MaximumVariableCount PGHome PGSE PGUICulture PGV
