Question

我有以下脚本。

function Sample-function
{

    Write-host "I am function"
}

function Sample-ScriptMethod
{


    $obj = [pscustomobject]@{}

    $obj | Add-Member -MemberType ScriptMethod -Name sm1 -Value {

        Write-host "I am scriptmethod1"
    }
    Write-host "I am troubling"
    $obj | Add-Member -MemberType ScriptMethod -Name sm2 -Value {

        Write-host "I am scriptmethod2"
    }
    $obj
}

使用AST我能够找到如下的函数名称。

function GEt-functionNames
{
    Param
    (
        $filepath="C:\repo\UnMapStress2\g2\lib\Common\Windows\NWPSF\tests\lib\Common\IOOperation.psm1"
    )

    $AST = [System.Management.Automation.Language.Parser]::ParseFile($filepath,[ref]$null,[ref]$Null)

    # Returns function name 
    $AST.FindAll({$args[0] -is [System.Management.Automation.Language.FunctionDefinitionAst]},$true) | foreach { $_.name}
}

Get-functionNames -filepath "C:\Users\Administrator\Desktop\ASTSample.ps1"

输出

Sample-function
Sample-ScriptMethod

我也想在文件中找到脚本方法。该文件有2个scriptmethods sm1和sm2。

如何在powershell中找到它们？ AST有找到它的方法吗？

更新：我试图找到使用以下方式，但无法找到

$filepath = "C:\Users\Administrator\Desktop\ASTSample.ps1"
$AST = [System.Management.Automation.Language.Parser]::ParseFile($filepath,[ref]$null,[ref]$Null)

    # Returns function name 
    $AST.FindAll({$args[0] -is [System.Management.Automation.Language.ScriptBlockExpressionAst]},$true) | foreach { $_.name}

您最后只在foreach中选择了Name属性。虽然类型[System.Management.Automation.Language.FunctionDefinitionAst]可能具有Name属性，但[System.Management.Automation.Language.ScriptBlockExpressionAst]却没有。

如果从代码中删除foreach，则可以看到ScriptBlocks。

# $AST = [System.Management.Automation.Language.Parser]::ParseFile($filepath,[ref]$null,[ref]$Null)
# $AST.FindAll({$args[0] -is [System.Management.Automation.Language.ScriptBlockExpressionAst]},$true) | fl


ScriptBlock : {

                      Write-host "I am scriptmethod1"
                  }
StaticType  : System.Management.Automation.ScriptBlock
Extent      : {

                      Write-host "I am scriptmethod1"
                  }
Parent      : Add-Member -MemberType ScriptMethod -Name sm1 -Value {

                      Write-host "I am scriptmethod1"
                  }

ScriptBlock : {

                      Write-host "I am scriptmethod2"
                  }
StaticType  : System.Management.Automation.ScriptBlock
Extent      : {

                      Write-host "I am scriptmethod2"
                  }
Parent      : Add-Member -MemberType ScriptMethod -Name sm2 -Value {

                      Write-host "I am scriptmethod2"
                  }

如何在powershell中使用AST查找脚本方法？
