Add option to include install-args in the `choco export` command

[jimbrig]

It would be nice to have a flag similar to the --include-version-numbers flag for the choco export command but for including the installation arguments of a given package (assuming the user has the configuration useRememberedArgumentsForUpgrades enabled).

Consider the following scenario where I install Git with various installation arguments applied:

cinst -y git.install --installargs "'/COMPONENTS=icons,assoc,assoc_sh,autoupdate,windowsterminal,scalar'" --params "/GitAndUnixToolsOnPath /NoAutoCrlf /WindowsTerminal /NoShellIntegration /NoGuiHereIntegration /NoShellHereIntegration /WindowsTerminalProfile /DefaultBranchName:main /Editor:VisualStudioCode"

then run choco export -o="choco-packages.config", however the output XML only contains:

<package id="git.install"/>

whereas it could contain something like so:

<package id="git.install" arguments=" --install-arguments=&quot;&apos;/COMPONENTS=icons,assoc,assoc_sh,autoupdate,windowsterminal,scalar&apos;&quot; --package-parameters=&quot;&apos;/GitAndUnixToolsOnPath /NoAutoCrlf /WindowsTerminal /NoShellIntegration /NoGuiHereIntegration /NoShellHereIntegration /WindowsTerminalProfile /DefaultBranchName:main /Editor:VisualStudioCode&apos;&quot;" />

This way, when I run cinst -y choco-packages.config it would apply the initial install-args and params for Git.

Proposed Solution: add --include-install-args flag to the choco export command.

I investigated a little further and found that installation arguments are stored under the path:
$env:ChocolateyInstall\.chocolatey\<package>.<version>\.arguments
(again, assuming the user has the config option useRememberedArgumentsForUpgrades enabled).

Therefore, to implement the proposed enhancement above to the export command, you could gather package specific installation arguments using some helper functions like these:

Add-Type -AssemblyName System.Security
$entropyBytes = [System.Text.UTF8Encoding]::UTF8.GetBytes("Chocolatey")

Function Unprotect-Arguments {
    param([string]$data)
    $encryptedByteArray = [System.Convert]::FromBase64String($data)
    $decryptedByteArray = [System.Security.Cryptography.ProtectedData]::Unprotect(
        $encryptedByteArray,
        $entropyBytes,
        [System.Security.Cryptography.DataProtectionScope]::LocalMachine
    )
    return [System.Text.UTF8Encoding]::UTF8.GetString($decryptedByteArray)
}

Function Read-Arguments {
    param([string]$packageName)
    $directory = Get-ChildItem $env:ChocolateyInstall\.chocolatey -Directory -Filter "$packageName*" | `
        Where-Object { $_.Name -match ("$packageName" + "\.[\d\.]+") } | Select-Object -Last 1
    If (!($directory)) { return }
    $argsFile = Join-Path $directory.fullname ".arguments"
    If (Test-Path $argsFile) {
        $argsData = Get-Content $argsFile
        #Implicitly return result from Unprotect-Arguments
        Unprotect-Arguments -data $argsData
    }
}

Function Get-LocalPackageInfo {
    & choco list -lo -r -y
}

Function Get-PackagesConfigBody($SaveArguments = $false) {
    Get-LocalPackageInfo | ForEach-Object {
        $packageName = $($_.SubString(0, $_.IndexOf("|")))
        $line = '   <package id="' + $packageName + '" '

        If ($SaveArguments) {
            $line = $line + 'arguments="' + [System.Security.SecurityElement]::Escape($(Read-Arguments $packageName)) + '" '
        }
    
        $line = $line + '/>'
        $line

    }
}

Function Write-PackagesConfig($OutputFile, $SaveArguments = $false) {
    $header = "<?xml version=`"1.0`" encoding=`"utf-8`"?>`n<packages>"
    $footer = "</packages>"
    $body = Get-PackagesConfigBody -SaveArguments $SaveArguments
    Write-Output $header $body $footer | Out-File $OutputFile -Encoding ASCII
}

and choco export -o="choco-packages.config" --include-install-args would utilize something like:

Write-PackagesConfig -OutputFile "choco-packages.config" -SaveArguments $true

Resulting in XML like this:

<?xml version="1.0" encoding="utf-8"?>
<packages>
   <package id="gh" arguments=" --cache-location=&quot;&apos;C:\Users\jimmy\AppData\Local\Temp\chocolatey&apos;&quot;" />
   <package id="git.install" arguments=" --cache-location=&quot;&apos;C:\Users\jimmy\AppData\Local\Temp\chocolatey&apos;&quot; --install-arguments=&quot;&apos;/COMPONENTS=icons,assoc,assoc_sh,autoupdate,windowsterminal,scalar&apos;&quot; --package-parameters=&quot;&apos;/GitAndUnixToolsOnPath /NoAutoCrlf /WindowsTerminal /NoShellIntegration /NoGuiHereIntegration /NoShellHereIntegration /WindowsTerminalProfile /DefaultBranchName:main /Editor:VisualStudioCode&apos;&quot;" />
</packages>

I tested this suite of functions locally and it worked exactly as mentioned above. Only potentially undesired aspect of the result is the --cache-location being included from the reading of the encrypted .chocolatey/<package>.<version>/.arguments file.

Here's the script I used (as .txt due to GitHub limitations):

Thanks for adding this issue, I had thought that there already was one posted for this feature request.

This is definitely something that is planned to be added at some point, but it would be in the C# code, not in the PowerShell helper functions. See #1825 for where it would go in.

Also, I discussed this with @gep13, and it is likely that the other install argument would be added with individual elements, instead of via a single arguments element. This would require that #886 be completed first, and makes changes so the code for parsing CLI arguments can be reused for saved arguments.

Will this add the state of pinned-packages like stated here?
#1825 (comment)

Exactly. So if I pinned VS Code on one machine, it would end up pinned on another machine.

Wasn't quite sure if I should open a new issue, but would find it quite useful to export this with choco export

Wasn't quite sure if I should open a new issue,

@Cyber1000 In this case, a new issue would be appropriate. The information about whether a package is pinned or not is stored separately from the saved arguments, and there is not currently a way to pin a package during installation (although I do have a PR open to add that).
