Package Approved

This package was approved as a trusted package on 12 Feb 2016.

Description

Chocolatey is a package manager for Windows (like apt-get but for Windows). It was designed to be a decentralized framework for quickly installing applications and tools that you need. It is built on the NuGet infrastructure currently using PowerShell as its focus for delivering packages from the distros to your door, err computer.

Chocolatey is brought to you by the work and inspiration of the community, the work and thankless nights of the Chocolatey Team, with Rob heading up the direction.

You can host your own sources and add them to Chocolatey, you can extend Chocolatey's capabilities, and folks, it's only going to get better.

Commands

There are quite a few commands you can call - you should check out the command reference. Here are the most common:

  • Help - choco -? or choco command -?
  • Search - choco search something
  • List - choco list -lo
  • Config - choco config list
  • Install - choco install baretail
  • Pin - choco pin windirstat
  • Outdated - choco outdated
  • Upgrade - choco upgrade baretail
  • Uninstall - choco uninstall baretail

Alternative installation sources:

  • Install ruby gem - choco install compass -source ruby
  • Install python egg - choco install sphynx -source python
  • Install windows feature - choco install IIS -source windowsfeatures
  • Install webpi feature - choco install IIS7.5Express -source webpi

For more advanced commands and switches, use choco -? or choco command -h. You can also look at the command reference, including how you can force a package to install the x86 version of a package.

Create Packages?

We have some great guidance on how to do that. Where? I'll give you a hint, it rhymes with sticky! Wiki!

In that mess there is a link to the Helper Reference.

function Get-ChocolateyUnzip {
<#
.SYNOPSIS
Unzips an archive file and returns the location for further processing.

.DESCRIPTION
This unzips files using the 7-zip standalone command line tool 7za.exe.
Supported archive formats are: 7z, lzma, cab, zip, gzip, bzip2, Z and tar.

.PARAMETER FileFullPath
This is the full path to your zip file.

.PARAMETER Destination
This is a directory where you would like the unzipped files to end up.
If it does not exist, it will be created.

.PARAMETER SpecificFolder
OPTIONAL - This is a specific directory within zip file to extract.

.PARAMETER PackageName
OPTIONAL - This will faciliate logging unzip activity for subsequent uninstall

.EXAMPLE
$scriptPath = (Split-Path -parent $MyInvocation.MyCommand.Definition)
Get-ChocolateyUnzip "c:\someFile.zip" $scriptPath somedirinzip\somedirinzip

.OUTPUTS
Returns the passed in $destination.

.NOTES
This helper reduces the number of lines one would have to write to unzip a file to 1 line.
If extraction fails, an exception is thrown.

.NOTES
When your installation script has to know what architecture it is run on, this simple function comes in handy.

## v3.3 - Add progress report for files which report their size
## v3.2 - Use the pure Stream object because StreamWriter is based on TextWriter:
##        it was messing up binary files, and making mistakes with extended characters in text
## v3.1 - Unwrap the filename when it has quotes around it
## v3   - rewritten completely using HttpWebRequest + HttpWebResponse to figure out the file name, if possible

function Install-ChocolateyExplorerMenuItem {
<#
.SYNOPSIS
Creates a windows explorer context menu item that can be associated with a command

.DESCRIPTION
Install-ChocolateyExplorerMenuItem can add an entry in the context menu of
Windows Explorer. The menu item is given a text label and a command. The command
can be any command accepted on the windows command line. The menu item can be
applied to either folder items or file items.

Because this command accesses and edits the root class registry node, it will be
elevated to admin.

.PARAMETER MenuKey
A unique string to identify this menu item in the registry

.PARAMETER MenuLabel
The string that will be displayed in the context menu

.PARAMETER Command
A command line command that will be invoked when the menu item is selected

.PARAMETER Type
Specifies if the menu item should be applied to a folder or a file

.EXAMPLE
C:\PS>$sublimeDir = (Get-ChildItem $env:ALLUSERSPROFILE\chocolatey\lib\sublimetext* | select $_.last)
C:\PS>$sublimeExe = "$sublimeDir\tools\sublime_text.exe"
C:\PS>Install-ChocolateyExplorerMenuItem "sublime" "Open with Sublime Text 2" $sublimeExe

This will create a context menu item in Windows Explorer when any file is right clicked. The menu item will appear with the text "Open with Sublime Text 2" and will invoke sublime text 2 when selected.
.EXAMPLE
C:\PS>$sublimeDir = (Get-ChildItem $env:ALLUSERSPROFILE\chocolatey\lib\sublimetext* | select $_.last)
C:\PS>$sublimeExe = "$sublimeDir\tools\sublime_text.exe"
C:\PS>Install-ChocolateyExplorerMenuItem "sublime" "Open with Sublime Text 2" $sublimeExe "directory"

This will create a context menu item in Windows Explorer when any folder is right clicked. The menu item will appear with the text "Open with Sublime Text 2" and will invoke sublime text 2 when selected.

.NOTES
Chocolatey will automatically add the path of the file or folder clicked to the command. This is done simply by appending a %1 to the end of the command.

.SYNOPSIS
Creates an association between a file extension and a executable

.DESCRIPTION
Install-ChocolateyFileAssociation can associate a file extension
with a downloaded application. Once this command has created an
association, all invocations of files with the specified extension
will be opened via the executable specified.

This command will run with elevated privileges.

.PARAMETER Extension
The file extension to be associated.

function Install-ChocolateyInstallPackage {
<#
.SYNOPSIS
Installs a package

.DESCRIPTION
This will run an installer (local file) on your machine.

.PARAMETER PackageName
The name of the package - this is arbitrary, call it whatever you want.
It's recommended you call it the same as your nuget package id.

.PARAMETER FileType
This is the extension of the file. This should be either exe or msi.

.PARAMETER SilentArgs
OPTIONAL - These are the parameters to pass to the native installer.
Try any of these to get the silent installer - /s /S /q /Q /quiet /silent /SILENT /VERYSILENT
With msi it is always /quiet.
If you don't pass anything it will invoke the installer with out any arguments. That means a nonsilent installer.

Please include the notSilent tag in your chocolatey nuget package if you are not setting up a silent package.

.PARAMETER File
The full path to the native installer to run

.EXAMPLE
Install-ChocolateyInstallPackage '__NAME__' 'EXE_OR_MSI' 'SILENT_ARGS' 'FilePath'

.OUTPUTS
None

.NOTES
This helper reduces the number of lines one would have to write to run an installer to 1 line.
There is no error handling built into this method.

function Install-ChocolateyPackage {
<#
.SYNOPSIS
Installs a package

.DESCRIPTION
This will download a file from a url and install it on your machine.

.PARAMETER PackageName
The name of the package we want to download - this is arbitrary, call it whatever you want.
It's recommended you call it the same as your nuget package id.

.PARAMETER FileType
This is the extension of the file. This should be either exe or msi.

.PARAMETER SilentArgs
OPTIONAL - These are the parameters to pass to the native installer.
Try any of these to get the silent installer - /s /S /q /Q /quiet /silent /SILENT /VERYSILENT
With msi it is always /quiet. Please pass it in still but it will be overridden by chocolatey to /quiet.
If you don't pass anything it will invoke the installer with out any arguments. That means a nonsilent installer.

Please include the notSilent tag in your chocolatey nuget package if you are not setting up a silent package.

.PARAMETER Url
This is the url to download the file from.

.PARAMETER Url64bit
OPTIONAL - If there is an x64 installer to download, please include it here. If not, delete this parameter

.PARAMETER Checksum
OPTIONAL (Right now) - This allows a checksum to be validated for files that are not local

.PARAMETER Checksum64
OPTIONAL (Right now) - This allows a checksum to be validated for files that are not local

.PARAMETER ChecksumType
OPTIONAL (Right now) - 'md5', 'sha1', 'sha256' or 'sha512' - defaults to 'md5'

.PARAMETER ChecksumType64
OPTIONAL (Right now) - 'md5', 'sha1', 'sha256' or 'sha512' - defaults to ChecksumType

.PARAMETER options
OPTIONAL - Specify custom headers

Example:
-------- 
  $options =
  @{
    Headers = @{
      Accept = 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';
      'Accept-Charset' = 'ISO-8859-1,utf-8;q=0.7,*;q=0.3';
      'Accept-Language' = 'en-GB,en-US;q=0.8,en;q=0.6';
      Cookie = 'requiredinfo=info';
      Referer = 'https://somelocation.com/';
    }
  }
  
  Get-ChocolateyWebFile 'package' 'https://somelocation.com/thefile.exe' -options $options

.EXAMPLE
Install-ChocolateyPackage '__NAME__' 'EXE_OR_MSI' 'SILENT_ARGS' 'URL' '64BIT_URL_DELETE_IF_NO_64BIT'

.OUTPUTS
None

.NOTES
This helper reduces the number of lines one would have to write to download and install a file to 1 line.
This method has error handling built into it.

function Test-ProcessAdminRights {

.SYNOPSIS
Tests whether the current process is running with administrative rights.

.DESCRIPTION
This function checks whether the current process has administrative rights
by checking if the current user identity is a member of the Administrators group.
It returns $true if the current process is running with administrative rights,
$false otherwise.

On Windows Vista and later, with UAC enabled, the returned value represents the
actual rights available to the process, i.e. if it returns $true, the process is
running elevated.

.OUTPUTS
System.Boolean

function Update-SessionEnvironment {
<#
.SYNOPSIS
Updates the environment variables of the current powershell session with
any environment variable changes that may have occured during a chocolatey
package install.

.DESCRIPTION
When chocolatey installs a package, the package author may add or change
certain environment variables that will affect how the application runs
or how it is accessed. Often, these changes are not visible to the current
powershell session. This means the user needs to open a new powershell
session before these settings take effect which can render the installed
application unfunctional until that time.

Use the Update-SessionEnvironment command to refresh the current
powershell session with all environment settings possibly performed by
chocolatey package installs.

  .DESCRIPTION
    This will initialize the Chocolatey tool by
      a) setting up the "chocolateyPath" (the location where all chocolatey nuget packages will be installed)
      b) Installs chocolatey into the "chocolateyPath"
            c) Instals .net 4.0 if needed
      d) Adds Chocolatey to the PATH environment variable so you have access to the choco commands.
  .PARAMETER  ChocolateyPath
    Allows you to override the default path of (C:\ProgramData\chocolatey\) by specifying a directory chocolatey will install nuget packages.

  .EXAMPLE
    C:\PS> Initialize-Chocolatey

    Installs chocolatey into the default C:\ProgramData\Chocolatey\ directory.

  .EXAMPLE
    C:\PS> Initialize-Chocolatey -chocolateyPath "D:\ChocolateyInstalledNuGets\"

    Installs chocolatey into the custom directory D:\ChocolateyInstalledNuGets\

Chocolatey
========================
Welcome to Chocolatey, your local machine repository built on the NuGet infrastructure. Chocolatey allows you to install application packages to your machine with the goodness of a #chocolatey #nuget combo. 
Application executables get added to the path automatically so you can call them from anywhere (command line/powershell prompt), not just in Visual Studio.

Lets get Chocolatey!
----------
Visual Studio -
----------
Please run Initialize-Chocolatey one time per machine to set up the repository. 
If you are upgrading, please remember to run Initialize-Chocolatey again.
After you have run Initiliaze-Chocolatey, you can safely uninstall the chocolatey package from your current Visual Studio solution.
----------
Alternative NuGet -
----------
If you are not using NuGet in Visual Studio, please navigate to the directory with the chocolateysetup.psm1 and run that in Powershell, followed by Initialize-Chocolatey.
Upgrade is the same, just run Initialize-Chocolatey again.
----------
Once you've run initialize or upgrade, you can uninstall this package from the local project without affecting your chocolatey repository.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.

See all - https://github.com/chocolatey/choco/blob/stable/CHANGELOG.md

0.9.10

What will be highlighted:

  • Alternative sources (webpi, windowsfeature, cygwin, etc) are back (finally, right?)!
  • Use an internal PowerShell host to take advantage of quite a few improvements!
  • Introduce managing package templates, reintroduce extensions.
  • Talk about using original download file name
  • Talk about the improvements in search information
  • Talk a little about what's coming with pro

BREAKING CHANGES

  • Only fail automation scripts (chocolateyInstall.ps1) if the script returns non-zero exit code - see #445
  • Fix - Force reinstall, force upgrade, and uninstall should delete the download cache - see #590

For 445 - the 0.9.8 series would only fail a package with terminating errors. The 0.9.9 series took that a bit further and started failing packages if anything wrote to stderr. It turns out that is a bad idea. Only when PowerShell exits with non-zero (which comes with terminating errors) should the package fail due to this. If you need the old behavior of the 0.9.9 series, you can get it back with a switch (--fail-on-standard-error and its aliases) and/or a feature flip (failOnStandardError).

For 590 - if you set a custom cache directory for downloads, it will no longer use a "chocolatey" subdirectory under that. You may need to make any adjustments if this is going to affect you.
