function Set-WhiskeyDotNetGlobalJson { <# .SYNOPSIS Sets values within a .NET Core global.json file. .DESCRIPTION The `Set-WhiskeyDotNetGlobalJson` function sets values within a .NET Core `global.json` file. If the `global.json` file does not exist in the given `Directory` then it will be created. If the `global.json` file already exists, then the function will only update the desired values and leave the rest of the content as-is. .EXAMPLE Set-WhiskeyDotNetGlobalJson -Directory 'C:\Build\app' -SdkVersion '2.1.4' Demonstrates setting the `sdk.version` property in global.json to '2.1.4'. #> [CmdletBinding()] param( [Parameter(Mandatory=$true)] [string] # The directory where the `global.json` will be created/modified. $Directory, [Parameter(Mandatory=$true)] [string] # The version of the SDK to set within the `global.json` file. $SdkVersion ) Set-StrictMode -version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState Write-Verbose -Message ('[{0}] Setting global.json properties: ''sdk.version'' => ''{1}''' -f $MyInvocation.MyCommand,$SdkVersion) if (-not (Test-Path -Path $Directory -PathType Container)) { Write-Error -Message ('The directory ''{0}'' does not exist.' -f $Directory) return } $globalJsonPath = Join-Path -Path $Directory -ChildPath 'global.json' Write-Verbose -Message ('[{0}] Looking for global.json at ''{1}''' -f $MyInvocation.MyCommand,$globalJsonPath) if (Test-Path -Path $globalJsonPath -PathType Leaf) { Write-Verbose -Message ('[{0}] Found existing global.json' -f $MyInvocation.MyCommand) Write-Verbose -Message ('[{0}] Updating ''{1}''' -f $MyInvocation.MyCommand,$globalJsonPath) try { $globalJson = Get-Content -Path $globalJsonPath -Raw | ConvertFrom-Json } catch { Write-Error -Message ('global.json file ''{0}'' contains invalid JSON.' -f $globalJsonPath) return } if (-not ($globalJson | Get-Member -Name 'sdk')) { $globalJson | Add-Member -MemberType NoteProperty -Name 'sdk' -Value ([pscustomobject]@{ }) } if (-not ($globalJson.sdk | Get-Member -Name 'version')) { $globalJson.sdk | Add-Member -MemberType NoteProperty -Name 'version' -Value ([pscustomobject]@{ }) } $globalJson.sdk.version = $SdkVersion } else { Write-Verbose -Message ('[{0}] global.json does not exist at ''{1}''' -f $MyInvocation.MyCommand,$globalJsonPath) Write-Verbose -Message ('[{0}] Creating ''{1}''' -f $MyInvocation.MyCommand,$globalJsonPath) $globalJson = @{ 'sdk' = @{ 'version' = $SdkVersion } } } $globalJson | ConvertTo-Json -Depth 100 | Set-Content -Path $globalJsonPath -Force Write-Verbose -Message ('[{0}] global.json update finished.' -f $MyInvocation.MyCommand) } |
