# Author: Miodrag Milic <miodrag.milic@gmail.com> # Last Change: 30-Oct-2016. <# .SYNOPSIS Update automatic package .DESCRIPTION This function is used to perform necessary updates to the specified files in the package. It shouldn't be used on its own but must be part of the script which defines two functions: - au_SearchReplace The function should return HashTable where keys are file paths and value is another HashTable where keys and values are standard search and replace strings - au_GetLatest Returns the HashTable where the script specifies information about new Version, new URLs and any other data. You can refer to this variable as the $Latest in the script. While Version is used to determine if updates to the package are needed, other arguments can be used in search and replace patterns or for whatever purpose. With those 2 functions defined, calling Update-Package will: - Call your au_GetLatest function to get the remote version and other information. - If remote version is higher then the nuspec version, function will: - Check the returned URLs, Versions and Checksums (if defined) for validity (unless NoCheckXXX variables are specified) - Download files and calculate checksum(s), (unless already defined or ChecksumFor is set to 'none') - Update the nuspec with the latest version - Do the necessary file replacements - Pack the files into the nuget package You can also define au_BeforeUpdate and au_AfterUpdate functions to integrate your code into the update pipeline. .EXAMPLE PS> notepad update.ps1 # The following script is used to update the package from the github releases page. # After it defines the 2 functions, it calls the Update-Package. # Checksums are automatically calculated for 32 bit version (the only one in this case) import-module au function global:au_SearchReplace { ".\tools\chocolateyInstall.ps1" = @{ "(^[$]url32\s*=\s*)('.*')" = "`$1'$($Latest.URL32)'" "(^[$]checksum32\s*=\s*)('.*')" = "`$1'$($Latest.Checksum32)'" "(^[$]checksumType32\s*=\s*)('.*')" = "`$1'$($Latest.ChecksumType32)'" } } function global:au_GetLatest { $download_page = Invoke-WebRequest -Uri https://github.com/hluk/CopyQ/releases $re = "copyq-.*-setup.exe" $url = $download_page.links | ? href -match $re | select -First 1 -expand href $version = $url -split '-|.exe' | select -Last 1 -Skip 2 return @{ URL32 = $url; Version = $version } } Update-Package -ChecksumFor 32 .NOTES All function parameters accept defaults via global variables with prefix `au_` (example: $global:au_Force = $true). .OUTPUTS PSCustomObject with type AUPackage. .LINK Update-AUPackages #> function Update-Package { [CmdletBinding()] param( #Do not check URL and version for validity.
