Description

The New-ModuleManifest cmdlet creates a new module manifest (.psd1) file, populates its values, and saves the manifest file in the specified path.

Module authors can use this cmdlet to create a manifest for their module. A module manifest is a .psd1 file that contains a hash table. The keys and values in the hash table describe the contents and attributes of the module, define the prerequisites, and determine how the components are processed. Manifests aren't required for a module.

New-ModuleManifest creates a manifest that includes all the commonly used manifest keys, so you can use the default output as a manifest template. To add or change values, or to add module keys that this cmdlet doesn't add, open the resulting file in a text editor.

Each parameter, except for Path and PassThru, creates a module manifest key and its value. In a module manifest, only the ModuleVersion key is required. Unless specified in the parameter description, if you omit a parameter from the command, New-ModuleManifest creates a comment string for the associated value that has no effect.

In PowerShell 2.0, New-ModuleManifest prompts you for the values of commonly used parameters that aren't specified in the command, in addition to required parameter values. Beginning in PowerShell 3.0, New-ModuleManifest prompts only when required parameter values aren't specified.

Examples

Example 1 - Create a new module manifest

This example creates a new module manifest in the file that is specified by the Path parameter. The PassThru parameter sends the output to the pipeline and to the file.

The output shows the default values of all keys in the manifest.

Example 2 - Create a new manifest with some prepopulated settings

This example creates a new module manifest. It uses the PowerShellVersion and AliasesToExport parameters to add values to the corresponding manifest keys.

New-ModuleManifest -PowerShellVersion 1.0 -AliasesToExport JKBC, DRC, TAC -Path C:\ps-test\ManifestTest.psd1

Example 3 - Create a manifest that requires other modules

This example uses a string format to specify the name of the BitsTransfer module and the hash table format to specify the name, a GUID, and a version of the PSScheduledJob module.

$moduleSettings = @{
  RequiredModules = ("BitsTransfer", @{
    ModuleName="PSScheduledJob"
    ModuleVersion="1.0.0.0";
    GUID="50cdb55f-5ab7-489f-9e94-4ec21ff51e59"
  })
  Path = 'C:\ps-test\ManifestTest.psd1'
}
New-ModuleManifest @moduleSettings

This example shows how to use the string and hash table formats of the ModuleList, RequiredModules, and NestedModules parameter. You can combine strings and hash tables in the same parameter value.

Example 4 - Create a manifest that supports updateable help

This example uses the HelpInfoUri parameter to create a HelpInfoUri key in the module manifest. The value of the parameter and the key must begin with http or https. This value tells the Updatable Help system where to find the HelpInfo XML updatable help information file for the module.

$moduleSettings = @{
  HelpInfoUri = 'http://http://go.microsoft.com/fwlink/?LinkID=603'
  Path = 'C:\ps-test\ManifestTest.psd1'
}
New-ModuleManifest @moduleSettings

Example 5 - Getting module information

This example shows how to get the configuration values of a module. The values in the module manifest are reflected in the values of properties of the module object.

The Get-Module cmdlet is used to get the Microsoft.PowerShell.Diagnostics module using the List parameter. The command sends the module to the Format-List cmdlet to display all properties and values of the module object.

Get-Module Microsoft.PowerShell.Diagnostics -List | Format-List -Property *

Accept pipeline input:False
Accept wildcard characters:False
-NestedModules

Specifies script modules (.psm1) and binary modules (.dll) that are imported into the module's session state. The files in the NestedModules key run in the order in which they're listed in the value.

Enter each module name as a string or as a hash table with ModuleName and ModuleVersion keys. The hash table can also have an optional GUID key. You can combine strings and hash tables in the parameter value.

Typically, nested modules contain commands that the root module needs for its internal processing. By default, the commands in nested modules are exported from the module's session state into the caller's session state, but the root module can restrict the commands that it exports. For example, by using an Export-ModuleMember command.

Nested modules in the module session state are available to the root module, but they aren't returned by a Get-Module command in the caller's session state.

Scripts (.ps1) that are listed in the NestedModules key are run in the module's session state, not in the caller's session state. To run a script in the caller's session state, list the script file name in the value of the ScriptsToProcess key in the manifest.

Type:Object[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PassThru

Writes the resulting module manifest to the console and creates a .psd1 file. By default, this cmdlet doesn't generate any output.

-Path

Specifies the path and file name of the new module manifest. Enter a path and file name with a .psd1 file name extension, such as $pshome\Modules\MyModule\MyModule.psd1. The Path parameter is required.

If you specify the path to an existing file, New-ModuleManifest replaces the file without warning unless the file has the read-only attribute.

The manifest should be located in the module's directory, and the manifest file name should be the same as the module directory name, but with a .psd1 file name extension.

Note

You cannot use variables, such as $PSHOME or $HOME, in response to a prompt for a Path parameter value. To use a variable, include the Path parameter in the command.

Type:String
Position:1
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PowerShellHostName

Specifies the name of the PowerShell host program that the module requires. Enter the name of the host program, such as Windows PowerShell ISE Host or ConsoleHost. Wildcards aren't permitted.

To find the name of a host program, in the program, type $Host.Name.

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PowerShellHostVersion

Specifies the minimum version of the PowerShell host program that works with the module. Enter a version number, such as 1.1.

Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ProjectUri

Specifies the URL of a web page about this project.

Type:Uri
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ReleaseNotes

Specifies release notes.

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-RequiredAssemblies

Specifies the assembly (.dll) files that the module requires. Enter the assembly file names. PowerShell loads the specified assemblies before updating types or formats, importing nested modules, or importing the module file that is specified in the value of the RootModule key.

Use this parameter to list all the assemblies that the module requires, including assemblies that must be loaded to update any formatting or type files that are listed in the FormatsToProcess or TypesToProcess keys, even if those assemblies are also listed as binary modules in the NestedModules key.

Type:String[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-RequiredModules

Specifies modules that must be in the global session state. If the required modules aren't in the global session state, PowerShell imports them. If the required modules aren't available, the Import-Module command fails.

Enter each module name as a string or as a hash table with ModuleName and ModuleVersion keys. The hash table can also have an optional GUID key. You can combine strings and hash tables in the parameter value.

In PowerShell 2.0, Import-Module doesn't import required modules automatically. It just verifies that the required modules are in the global session state.

Type:Object[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-RootModule

Specifies the primary or root file of the module. Enter the file name of a script (.ps1), a script module (.psm1), a module manifest(.psd1), an assembly (.dll), a cmdlet definition XML file (.cdxml), or a workflow (.xaml). When the module is imported, the members that are exported from the root module file are imported into the caller's session state.

If a module has a manifest file and no root file was designated in the RootModule key, the manifest becomes the primary file for the module, and the module becomes a manifest module (ModuleType = Manifest).

To export members from .psm1 or .dll files in a module that has a manifest, the names of those files must be specified in the values of the RootModule or NestedModules keys in the manifest. Otherwise, their members aren't exported.

Note

In PowerShell 2.0, this key was called ModuleToProcess. You can use the RootModule parameter name or its ModuleToProcess alias.

Type:String
Aliases:ModuleToProcess
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ScriptsToProcess

Specifies script (.ps1) files that run in the caller's session state when the module is imported. You can use these scripts to prepare an environment, just as you might use a login script.

To specify scripts that run in the module's session state, use the NestedModules key.

Type:String[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Tags

Specifies an array of tags.

Type:String[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-TypesToProcess

Specifies the type files (.ps1xml) that run when the module is imported.

When you import the module, PowerShell runs the Update-TypeData cmdlet with the specified files. Because type files aren't scoped, they affect all session states in the session.

Type:String[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-VariablesToExport

Specifies the variables that the module exports. Wildcards are permitted.

You can use this parameter to restrict the variables that are exported by the module. It can remove variables from the list of exported variables, but it can't add variables to the list.

If you omit this parameter, New-ModuleManifest creates a VariablesToExport key with a value of * (all), meaning that all variables defined in the module are exported by the manifest.

Type:String[]
Position:Named
Default value:* (all)
Accept pipeline input:False
Accept wildcard characters:True
-WhatIf

Shows what would happen if New-ModuleManifest runs. The cmdlet isn't run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

None

You can't pipe input to this cmdlet.

Outputs

None or System.String

By default, New-ModuleManifest doesn't generate any output. However, if you use the PassThru parameter, it generates a System.String object representing the module manifest.

Notes

New-ModuleManifest creates module manifest (.psd1) files encoded as UTF16.

Module manifests are usually optional. However, a module manifest is required to export an assembly that is installed in the global assembly cache.

To add or change files in the $pshome\Modules directory, start PowerShell with the Run as administrator option.

In PowerShell 2.0, many parameters of New-ModuleManifest were mandatory, even though they weren't required in a module manifest. Beginning in PowerShell 3.0, only the Path parameter is mandatory.

A session is an instance of the PowerShell execution environment. A session can have one or more session states. By default, a session has only a global session state, but each imported module has its own session state. Session states allow the commands in a module to run without affecting the global session state.

The caller's session state is the session state into which a module is imported. Typically, it refers to the global session state, but when a module imports nested modules, the caller is the module and the caller's session state is the module's session state.
