# PowerShell Functions aka Helpers Reference

<!-- This documentation file is automatically generated from the files at $sourceFunctions using $($sourceLocation)GenerateDocs.ps1. Contributions are welcome at the original location(s). -->

## Summary

In your Chocolatey packaging, you have the ability to use these functions (and others with Chocolatey's [PowerShell Extensions](xref:extensions)) to work with all aspects of software management. Keep in mind Chocolatey's automation scripts are just PowerShell, so you can do manage anything you want.

> :memo: **NOTE** These scripts are for package scripts, not for use directly in PowerShell. This is in the create packages section, not the using Chocolatey section.

## Main Functions

These functions call other functions and many times may be the only thing you need in your [chocolateyInstall.ps1 file](xref:chocolatey-install-ps1).

* [Install-ChocolateyPackage](xref:install-chocolateypackage)
* [Install-ChocolateyZipPackage](xref:install-chocolateyzippackage)
* [Install-ChocolateyPowershellCommand](xref:install-chocolateypowershellcommand)
* [Install-ChocolateyVsixPackage](xref:install-chocolateyvsixpackage)

## Error / Success Functions

* [Write-ChocolateySuccess](xref:write-chocolateysuccess) - **DEPRECATED**
* [Write-ChocolateyFailure](xref:write-chocolateyfailure) - **DEPRECATED**

You really don't need a try catch with Chocolatey PowerShell files anymore.

## More Functions

### Administrative Access Functions

When creating packages that need to run one of the following commands below, one should add the tag `admin` to the nuspec.

* [Install-ChocolateyPackage](xref:install-chocolateypackage)
* [Start-ChocolateyProcessAsAdmin](xref:start-chocolateyprocessasadmin)
* [Install-ChocolateyInstallPackage](xref:install-chocolateyinstallpackage)
* [Install-ChocolateyPath](xref:install-chocolateypath) - when specifying machine path
* [Install-ChocolateyEnvironmentVariable](xref:install-chocolateyenvironmentvariable) - when specifying machine path
* [Install-ChocolateyExplorerMenuItem](xref:install-chocolateyexplorermenuitem)
* [Install-ChocolateyFileAssociation](xref:install-chocolateyfileassociation)

### Non-Administrator Safe Functions

When you have a need to run Chocolatey without Administrative access required (non-default install location), you can run the following functions without administrative access.

These are the functions from above as one list.

* [Install-ChocolateyZipPackage](xref:install-chocolateyzippackage)
* [Install-ChocolateyPowershellCommand](xref:install-chocolateypowershellcommand)
* [Write-ChocolateySuccess](xref:write-chocolateysuccess)
* [Write-ChocolateyFailure](xref:write-chocolateyfailure)
* [Get-ChocolateyWebFile](xref:get-chocolateywebfile)
* [Get-ChocolateyUnzip](xref:get-chocolateyunzip)
* [Install-ChocolateyPath](xref:install-chocolateypath) - when specifying user path
* [Install-ChocolateyEnvironmentVariable](xref:install-chocolateyenvironmentvariable) - when specifying user path
* [Install-ChocolateyDesktopLink](xref:install-chocolateydesktoplink) - **DEPRECATED** - see [Install-ChocolateyShortcut](xref:install-chocolateyshortcut)
* [Install-ChocolateyPinnedTaskBarItem](xref:install-chocolateypinnedtaskbaritem)
* [Install-ChocolateyShortcut](xref:install-chocolateyshortcut) - v0.9.9+
* [Update-SessionEnvironment](xref:update-sessionenvironment)
* [Get-PackageParameters](xref:get-packageparameters) - v0.10.8+

## Chocolatey for Business Functions

 * [Install-ChocolateyWindowsService](xref:install-chocolateywindowsservice)
 * [Start-ChocolateyWindowsService](xref:start-chocolateywindowsservice)
 * [Stop-ChocolateyWindowsService](xref:stop-chocolateywindowsservice)
 * [Uninstall-ChocolateyWindowsService](xref:uninstall-chocolateywindowsservice)

## Variables

There are also a number of environment variables providing access to some values from the nuspec and other information that may be useful. They are accessed via `$env:variableName`.

### Environment Variables

Chocolatey makes a number of environment variables available (You can access any of these with $env:TheVariableNameBelow):

 * TEMP/TMP - Overridden to the CacheLocation, but may be the same as the original TEMP folder
 * ChocolateyInstall - Top level folder where Chocolatey is installed
 * ChocolateyPackageName - The name of the package, equivalent to the `<id />` field in the nuspec (0.9.9+)
 * ChocolateyPackageTitle - The title of the package, equivalent to the `<title />` field in the nuspec (0.10.1+)
 * ChocolateyPackageVersion - The version of the package, equivalent to the `<version />` field in the nuspec (0.9.9+)
 * ChocolateyPackageFolder - The top level location of the package folder - the folder where Chocolatey has downloaded and extracted the NuGet package, typically `C:\ProgramData\chocolatey\lib\packageName`.

#### Advanced Environment Variables

The following are more advanced settings:

 * ChocolateyPackageParameters - Parameters to use with packaging, not the same as install arguments (which are passed directly to the native installer). Based on `--package-parameters`. (0.9.8.22+)
 * CHOCOLATEY_VERSION - The version of Choco you normally see. Use if you are 'lighting' things up based on choco version. (0.9.9+) - Otherwise take a dependency on the specific version you need.
 * ChocolateyForceX86 = If available and set to 'true', then user has requested 32bit version. (0.9.9+) - Automatically handled in built in Choco functions.
 * OS_PLATFORM - Like Windows, OSX, Linux. (0.9.9+)
 * OS_VERSION - The version of OS, like 6.1 something something for Windows. (0.9.9+)
 * OS_NAME - The reported name of the OS. (0.9.9+)
