function Add-BMObjectParameter
{
    <#
    .SYNOPSIS
    Adds id or name values to a parameter hashtable (i.e. a hashtable used as the body of a request to a BuildMaster API
    endpoint).
 
    .DESCRIPTION
    Many of BuildMaster's APIs take an ID or a name. For example, many of the Release and Build Deployment methods
    accept either an `applicationId` parameter *or* an `applicationName` parameter. This function exists to allow
    BuildMasterAutomation functions to accept an object, an object's id or an object's name as a parameter. Pipe the
    hashtable that will be used as the body of a request to the BuildMaster APIs to `Add-BMObjectParameter`. Pass the
    name of the object type to the `Name` parameter and the object/id/name/value to the `Value` parameter.
 
    If the value passed is `$null`, nothing happens. If the value passed is a byte or an integer, the function adds a
    `$($Name)Id` parameter to the hashtable. If the value passed is a string, the function adds a `$($Name)Name`
    parameter. Otherwise, `Add-BMObjectParameter` the first property on the property named `id`, `$($Name)Id`, `name`,
    or `$($Name)Name` is added as `$($Name)Id` or `$($Name)Name` respectively.
 
    If the parameter must be a name parameter, use the `AsName` switch. If the parameter must be an id parameter, use
    the `AsID` switch.
 
    If the hashtable will be used as the body to a native API endpoint, use the `-ForNativeApi` switch. The native API
    uses `$($Name)_Id` and `$($Name)_Name` patterns for its id and name parameters.
 
    If you want to return the original hasthable so you can add more than one parameter to the hashtable, use the
    `-PassThru` switch.
 
    .EXAMPLE
    $parameters | Add-BMObjectParameter -Name 'release' -Value $release
 
    Demonstrates how to add the id property from an object to a hashtable used as the body to a BuildMaster API
    endpoint. In this case, `$release` is a release object returned by the BuildMaster APi, so has a `releaseId`
    property. `Add-BMObjectParameter` will add a `releaseId` key to the hashtable with a value of `$release.releaseId`.
 
    .EXAMPLE
    $parameters | Add-BMObjectParameter -Name 'release' -Value $releaseId
 
    Demonstrates how to add an id to a hashtable used as the body to a BuildMaster API. In this case, `$releaseId` is
    the id of a release. `Add-BMObjectParameter` will add a `releaseId` key to the hashtable with a value of
    `$releaseId`.
 
    .EXAMPLE
    $parameters | Add-BMObjectParameter -Name 'release' -Value $releaseName
 
    Demonstrates how to add a name to a hashtable used as the body to a BuildMaster API. In this case, `$releaseName` is
    the name of a release. `Add-BMObjectParameter` will add a `releaseName` key to the hashtable with a value of
    `$releaseName`.
 
    .EXAMPLE
    $parameters | Add-BMObjectParameter -Name 'pipeline' -Value $pipeline -AsName
 
    Demonstrates how to force `Add-BMObjectParameter` to ignore any id properties and only use name properties, if they
    exist, by using the `AsName` switch.
 
    .EXAMPLE
    $parameters | Add-BMObjectParameter -Name 'application' -Value $app -ForNativeApi
 
    Demonstrates how to add an id parameter to a parameter hashtable used as the body of a request to the BuildMaster
    *Native* API. In this case, `$app` is an application object returned by the BuildMaster API. `Add-BMObjectParameter`
    will add an `application_Id` key to the hasthable with a value of `$app.application_Id`.
 
    .EXAMPLE
    $parameter | Add-BMObjectParameter -Name 'application' -Value $app -PassThru | Add-BMObjectParameter -Name 'pipeline' -Value $pipeline
 
    Demonstrates how you can use the `PassThru` switch to add multiple parameters to a parameters hashtable using a
    pipeline.

function Add-BMParameter
{
    <#
    .SYNOPSIS
    Adds values to a parameter hashtable (i.e. a hashtable used as the body of a request to a BuildMaster API endpoint).
 
    .DESCRIPTION
    The `Add-BMParameter` function adds values to a parameter hashtable. Pipe the hashtable to the function (or pass it
    to the `Parameter` parameter). Pass the parameter name to the `Name` parameter and the value to the `Value`
    parameter. If the value is not null, it will be added to the hashtable.
 
    This function lets you simplify adding optional parameters to a parameter hashtable. Instead of:
 
         if ($null -ne $Value)
         {
            $parameters[$Name] = $Value
         }
 
    this function lets you write:
 
        $parameters | Add-BMParameter -Name $Name -Value $Value
 
    It also lets you chain multiple parameters together by using the `-PassThru` switch:
 
        $parameters |
            Add-BMParameter -Name $Name1 -Value $Value1 -PassThru |
            Add-BMParameter -Name $Name2 -Value $Value2 -PassThru |
            Add-BMParameter -Name $Name3 -Value $Value3
 
    .EXAMPLE
    $parameters | Add-BMParameter -Name $Name -Value $Value
 
    Demonstrates how to add an optional parameter to the parameter hashtable `$parameters`. In this case, if `$Value`
    is not null, `Add-BMParameter` adds `$Value` into `$parameters` using key `$Name`, e.g.
    `$parameters[$Name] = $Value`.
 
    .EXAMPLE
    $parameters | Add-BMParameter -Name $Name -Value $Value -PassThru | Add-BMParameter -Name $Name2 -Value $Value2
 
    Demonstrates how you can add multiple parameters to a parameter hashtable by using the `-PassThru` switch, which
    returns the parameter hashtable, which be piped to `Add-BMParameter`.

    Gets the ID from a BuildMaster object.
 
    .DESCRIPTION
    The `Get-BMObjectID` gets the value of the ID from a BuildMaster object. Pipe the object to the function (or pass
    it to the `InputObject` property). Pass the object type name to the `ObjectTypeName` property. The function
    inspects the object passed in and:
 
    * if the object is $null, returns $null.
    * if the object is a numeric value, returns it.
    * returns the value of the object's `id` property, if it exists.
    * returns the value of the object's `$(ObjectTypeName)_Id` (e.g. Raft_Id, Application_Id) property, if it exists.
    * returns the value of the object's `$(ObjectTypeName)Id` property, if it exists.
    * if it can't find an id, writes an error and returns nothing.
 
    If you know the exact name of the property you want returned as an id, pass its name to the `PropertyName`
    parameter. In this case, the function inspects the object passed in and:
 
    * if the object is $null, returns $null.
    * if the object is a numeric value, returns it.
    * returns the value of the object's `$PropertyName` property, if it exists.
 
    .EXAMPLE
    1 | Get-BMObjectID -ObjectNameType DoesNotMatter
 
    Demonstrates that `Get-BMObjectID` will always return any integer value it is passed.
 
    .EXAMPLE
    $raft | Get-BMObjectID -ObjectTypeName 'Raft'
 
    Demonstrates how to get the id from an object returned by any BuildMaster API. In this case, the object is a raft,
    and the function will return the value of the first of these properties to exist: `id`, `Raft_Id`, `RaftId`.
 
    .EXAMPLE

function Get-BMObjectName
{
    <#
    .SYNOPSIS
    Returns the name of an object that was returned by the BuildMaster API.
 
    .DESCRIPTION
    The BuildMasterAutomation module allows you to pass ids, names, or objects as the value to many parameters. Use the
    `Get-BMObjectName` function to get the name of one of these parameter values.
 
    If passed a string or an id, those will be returned as the name. Otherwise, the function looks for a `Name`
    property, a property matching wildcard `*_Name`, and then a property matching wildcard `*Name`, and returns the
    value of the first property found. If no properties are found, the function writes an error.
 
    If an object has multiple properties that could be its name, pass the name of the property to use to the
    `PropertyName` function.
 
    .EXAMPLE
    $app | Get-BMObjectName
 
    Demonstrates how to get the name of an application object. In this case, the value of the application's
    `Application_Name` property will be returned.

    The `Get-BMPipeline` function gets all pipelines. You can filter the list of pipelines by raft, pipeline name, and
    application by using the `Raft`, `Pipeline`, and `Application` parameters, respectively. To get only pipelines in a
    specific raft, pass the raft id or a raft object to the `Raft` parameter. To get a specific pipeline, pass its name
    or a pipeline object to the `Pipeline` parameter. To get pipelines for a specific application, pass the
    application id or application object to the `Application` parameter. If using multiple filter parameters, only
    pipelines that match all the filter parameters are returned.
 
    To search for a pipeline using a wildcard, pass a wildcard pattern to the `Pipeline` parameter.
 
    This function uses the `Rafts_GetRaftItems` native API method.

    To get a specific release, pass a release object, release ID, or release name to the `Release` parameter. If the
    release doesn't exist, the function will write an error.
 
    To get all the releases for a specific application, pass an application object, application ID, or application name
    to the `Application` parameter. You can get a specific application's release by passing the release's name to the
    `Name` parameter.
 
    .EXAMPLE
    Get-BMRelease -Session $session -Release $release
 
    Demonstrates how to get a specific release by passing a release object to the `Release` parameter. The
    `Get-BMRelease` function looks for an `id` or `name` property on the object.
 
    .EXAMPLE

    The `Get-BMServer` function gets all the servers from an instance of BuildMaster. To return a specific server,
    pipe the server's id, name (wildcards supported), or a server object to the function (or pass to the `Server`
    parameter). If the server doesn't exist, the function writes an error.
 
    The BuildMaster API returns plaintext versions of a server's API key (if it is using AES encryption). This function
    converts those keys into `SecureString` objects to make it harder to accidentally view/save them.
 
    This function uses BuildMaster's infrastructure management API.
 
    .EXAMPLE
    Get-BMServer
 
    Demonstrates how to return a list of all BuildMaster servers.

function Get-BMVariable
{
    <#
    .SYNOPSIS
    Gets BuildMaster variables.
 
    .DESCRIPTION
    The `Get-BMVariable` function gets BuildMaster variables. By default, it gets all global variables. It can also get
    all variables for a specific environment, server, server role, application group, application, release, and build.
 
    To get a specific variable, pass the variable's id, name, or object `Variable` parameter. If the variable doesn't
    exist, the function writes an error. To search for a variable, pass a wildcard string to the `Variable` parameter.
 
    To get an environment's variables, pass the environment's id, name, or object to the `Environment` parameter.
 
    To get a server role's variables, pass the server role's name to the `ServerRole` parameter.
 
    To get a server's variables, pass the server's name to the `Server` parameter.
 
    To get an application group's variables, pass the application group's name to the `ApplicationGroup` parameter.
 
    To get an application's variables, pass the application's name to the `Application` parameter.
 
    To get a release's variables, pass the release object to the `Release` parameter. Use the `Get-BMRelease` function
    to get a release object.
 
    To get a build's variables, pass the build object to the `Build` parameter. Use the `Get-BMBuild` function to get a
    build object.
 
    This function returns the variable value as a PowerShell data structure. If the variable is an OtterScript vector,
    it converts it to a PowerShell array; if it is an OtterScript map, it converts it to a PowerShell hashtable. To
    return the variable value in its original OtterScript form as a PowerShell string, use the `Raw` switch.
 
    This function uses BuildMaster's [Variables Management](https://docs.inedo.com/docs/buildmaster-reference-api-variables)
    API. Due to a bug in BuildMaster, when getting application or application group variables, it uses BuildMaster's
    native API.

function New-BMApplication
{
    <#
    .SYNOPSIS
    Creates an application in BuildMaster.
 
    .DESCRIPTION
    The `New-BMApplication` function creates an application in BuildMaster. This function uses the native BuildMaster
    API. Only a name is required to create an application. The name must be unique and not in use.
 
    These parameters are also available:
 
    * `ReleaseNumberScheme`: sets the release number scheme to use when you create a new release for the application
    Options are `MajorMinorRevision`, `MajorMinor`, or `DateBased`.
    * `BuildNumberScheme`: sets the build number scheme to use when creating new builds for an application.
    Options are `Unique`, `Sequential`, `DateBased`.
    * `Raft` to set the raft in which the application's scripts, pipelines, etc. should be saved.
 
    .EXAMPLE
    New-BMApplication -Session $session -Name 'MyNewApplication'
 
    Demonstrates the simplest way to create an application. In this example, a `MyNewApplication` application will be
    created and all its fields set to BuildMaster's default values.
 
    .EXAMPLE
    New-BMApplication -Session $session -Name 'MyNewApplication' -ReleaseNumberSchemeName MajorMinor -BuildNumberSchemeName Sequential
 
    This example demonstrates all the fields you can set when creating a new application. In this example, the new
    application will be called `MyNewApplication`, its release number scheme will be `MajorMinor`, and its build number
    schema will be `Sequential`.

function New-BMBuild
{
    <#
    .SYNOPSIS
    Creates a new build for a release.
 
    .DESCRIPTION
    The `New-BMBuild` creates a new version/build of an application. In order to deploy an application, the application
    must have a release. Then you create builds in that release, and each build is then deployed using the release's
    pipeline.
 
    .EXAMPLE
    New-BMBuild -Session $session -Release $release
 
    Demonstrates how to create a new build in the `$release` release. BuildMaster detects what application based on the
    release (since releases are always tied to applications). Verion numbers and build numbers are incremented and
    handled based on the release settings.
 
    The `$release` parameter can be:
 
    * A release object with an `id` property.
    * A release ID integer.
 
    .EXAMPLE
    New-BMBuild -Session $session -ReleaseName '53' -Application $applicatoin
 
    Demonstrates how to create a new build by using the release's name. Since release names are only unique within an
    application, you must also specify the application via the `Application` parameter.
 
    .EXAMPLE
    New-BMBuild -Session $session -Release $release -PacakgeName '56.develop' -Variable @{ ProGetPackageName = '17.1.54+developer.deadbee' }
 
    Demonstrates how to create a release with a specific name, `56.develop`, and with a build-level variable,
    `ProGetPackageName`.

    underscore or dash. Every environment must have a unique name. If you create a environment with a duplicate name,
    the BuildMaster error returns an error.
 
    You can set an new environment's parent environment with the `ParentName` parameter. You can create an inactive
    environment by using the `Inactive` switch.
 
    To return the environment, even if it already exists, use the `PassThru` switch.
 
    This function uses BuildMaster's infrastructure management API.

    <#
    .SYNOPSIS
    Creates a new server in a BuildMaster instance.
 
    .DESCRIPTION
    The `New-BMServer` function creates a new server in BuildMaster. Pass the name of the server to the `Name` parameter. Names may only contain letters, numbers, underscores, or dashes; they must begin with a letter; they must not end with dash or underscore. Pass the server type to the `Type` parameter. Type must be one of 'windows', 'powershell', 'ssh', or 'local'.
 
    Every server must have a unique name. If you create a server with a duplicate name, you'll get an error.
 
    This function uses BuildMaster's infrastructure management API.
 
    Pass a session object representing the instance of BuildMaster to use to the `Session` parameter. Use the `New-BMSession` function to create session objects.

    The `Set-BMPipeline` function creates or updates a pipeline in BuildMaster. Pass the name of the pipeline to the
    `Name` parameter. Pass the raft id or a raft object where the pipeline should be saved to the `Raft` parameter. A
    global pipeline will be created with no stages.
 
    To assign the pipeline to an application, pass the application's id, name or an application object to the
    `Application` parameter.
 
    To set the stages of the pipeline, use the `New-BMPipelineStageObject` and `New-BMPipelineStageTargetObject`
    functions to create the stages, then pass them to the `Stage` parameter. If the pipeline exists, you can use
    `Get-BMPipeline` to get the pipeline, modify its stage objects, then pass them to the `Stage` parameter.
 
    To set the post-deployment options of the pipeline, use `New-BMPipelinePostDeploymentOptionsObject` to create a
    post-deployment options object and pass that object to the `PostDeploymentOption` parameter.
 
    To set the color of the pipeline, pass the color in CSS RGB color format (e.g. `#aabbcc`) to the `Color` parameter.
 
    If you want stage order to be enforced by the pipeline, use the `EnforceStageSequence` switch.
 
    Any parameters *not* provided are not sent to BuildMaster in the create/update request. Those values won't be
    updated by BuildMaster. Any parameter you pass will cause the respective pipeline property to get updated to that
    value.
 
    This function uses [BuildMaster's native API](http://inedo.com/support/documentation/buildmaster/reference/api/native).
 
    .EXAMPLE
    Set-BMPipeline -Session $session -Name 'Powershell Module'

function Set-BMRaftItem
{
    <#
    .SYNOPSIS
    Creates or updates a raft item in BuildMaster.
 
    .DESCRIPTION
    The `Set-BMRaftItem` function creates or updates a raft item in BuildMaster. Pass the raft item's name to the
    `Name` parameter. Pass the raft item's raft id or a raft object to the `Raft` parameter. Pass the object's
    type to the `TypeCode` parameter. The raft item will be created if it doesn't exist, or updated if it does.
 
    To assign the raft item to a specific application, pass the application's id, name or an application object to the
    `Application` parameter. The application must be configured to use the same raft as the raft item. If it doesn't,
    you'll get an error.
 
    Pass the raft item's content to the `Content` parameter.
 
    Pass the username of the user creating/updating the raft item to the `UserName` parameter. The default username is
    `DOMAIN\UserName` if the current computer is in a Microsoft domain, `UserName@MachineName` otherwise.
 
    If you want the created/updated raft item's object to be returned, use the `PassThru` switch.
 
    When creating scripts, the name of the raft item should end with an extension for the type of script it is, e.g.
    `.ps1` for PowerShell scripts, `.sh` for shell scripts, etc.
 
    Parameters not passed will not be sent to BuildMaster, and typically BuildMaster leaves those values as-is. Any
    parameter that you pass will get sent to BuildMaster and the respective raft item properties will be updated.
 
    .EXAMPLE
    Set-BMRaftItem -Session $session -Raft $raft -TypeCode Pipeline -Name 'Pipeline'
 
    Demonstrates how to use Set-BMRaftItem. In this example, an empty, global pipeline will be created in the raft
    represented by the `$raft` object.
 
    .EXAMPLE
    Set-BMRaftItem -Session $session -Raft $raft -TypeCode Module -Name 'Module' -Application $app -Content $otterScript
 
    Demonstrates how to use Set-BMRaftItem. In this example, a module will be created/updated for the application
    represented by the `$app` object with the content in the `$otterScript` variable.

function Set-BMVariable
{
    <#
    .SYNOPSIS
    Create or set a BuildMaster variable.
 
    .DESCRIPTION
    The `Set-BMVariable` function creates or sets the value of a BuildMaster variable. By default, it creates/sets
    global variables. It can also set variables for a specific environment, server, server role, application group,
    application, release, and build.
 
    Pass the variable's name to the `Name` parameter and pass the variable's value to the `Value` parameter.
 
    The function takes variable values as PowerShell data structures and converts them to OtterScript expressions before
    they're passed to BuildMaster. A PowerShell hashtable is converted to an OtterScript map, a PowerShell array is
    converted to an OtterScript vector, and any other types are passed as their default string representation.
 
    Use the `Raw` switch to pass the variable value as-is to BuildMaster, i.e. no type conversion.
 
    To set an environment's variable, pass the environment's name to the `EnvironmentName` parameter.
 
    To set a server role's variable, pass the server role's name to the `ServerRoleName` parameter.
 
    To set a server's variable, pass the server's name to the `ServerName` parameter.
 
    To set an application group's variable, pass the application group's name to the `ApplicationGroupName` parameter.
 
    To set an application's variable, pass the application's name to the `ApplicationName` parameter.
 
    To set a release's variable, pass the release object to the `Release` parameter. Use the `Get-BMRelease` function to
    get a release object.
 
    To set a build's variable, pass the build object to the `Build` parameter. Use the `Get-BMBuild` function to get a
    build object.
 
    Pass a session object representing the instance of BuildMaster to use to the `Session` parameter. Use
    `New-BMSession` to create a session object.
 
    This function uses BuildMaster's variables API.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value'
 
    Demonstrates how to create or set a global variable.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value' -EnvironmentName 'Dev'
 
    Demonstrates how to create or set a variable in an environment.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value' -ServerRoleName 'WebApp'
 
    Demonstrates how to create or set a variable for a server role.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value' -ServerName 'example.com'
 
    Demonstrates how to create or set a variable for a server.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value' -ApplicationGroupName 'WebApps'
 
    Demonstrates how to create or set a variable for an application group.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value' -ApplicationName 'www'
 
    Demonstrates how to create or set a variable for an application.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value' -Release (Get-BMRelease -Session $session -Release 'gitflow' -Application 'WebApp')
 
    Demonstrates how to set a variable for a release.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'Var' -Value 'Value' -Build (Get-BMBuild -Session $session -Build 123)
 
    Demonstrates how to set a variable for a build.
 
    .EXAMPLE
    Set-BMVariable -Session $session -Name 'var' -Value @('hi', 'there') -ApplicationName 'www'
 
    Demonstrates how to set the variable 'var' to an OtterScript vector.

function Use-CallerPreference

    .SYNOPSIS
    Sets the PowerShell preference variables in a module's function based on the callers preferences.
 
    .DESCRIPTION
    Script module functions do not automatically inherit their caller's variables, including preferences set by common parameters. This means if you call a script with switches like `-Verbose` or `-WhatIf`, those that parameter don't get passed into any function that belongs to a module.
 
    When used in a module function, `Use-CallerPreference` will grab the value of these common parameters used by the function's caller:
 
     * ErrorAction
     * Debug
     * Confirm
     * InformationAction
     * Verbose
     * WarningAction
     * WhatIf
     
    This function should be used in a module's function to grab the caller's preference variables so the caller doesn't have to explicitly pass common parameters to the module function.
 
    This function is adapted from the [`Get-CallerPreference` function written by David Wyatt](https://gallery.technet.microsoft.com/scriptcenter/Inherit-Preference-82343b9d).
 
    There is currently a [bug in PowerShell](https://connect.microsoft.com/PowerShell/Feedback/Details/763621) that causes an error when `ErrorAction` is implicitly set to `Ignore`. If you use this function, you'll need to add explicit `-ErrorAction $ErrorActionPreference` to every function/cmdlet call in your function. Please vote up this issue so it can get fixed.
