The existing file is replaced. Change to the VSCode workspace directory before invoking the script. Generated VSCode tasks call Invoke-Build tasks. Do not edit "tasks.json" directly. Edit the build script instead. When you add, remove, rename tasks, or change script locations then regenerate. The default task becomes the so called VSCode build task (Ctrl+Shift+B). The default task is "." if it exists, otherwise it is the first task. To invoke another task from VSCode, hit F1 or Ctrl+Shift+P, type "Run Task", type a task name or select it from the task list. Even better, set your keyboard shortcut for "workbench.action.tasks.runTask". Only tasks with certain names are included. They contain alphanumeric characters, "_", ".", and "-", with the first character other than "-". .Parameter BuildFile Specifies the build script path, absolute or relative. By default it is the default script in the current location, i.e. in the workspace root. .Parameter InvokeBuild Specifies the Invoke-Build.ps1 path, absolute or relative. If it is not specified then any found in the workspace is used. If there is none then the command Invoke-Build is used. .Example > New-VSCodeTask This command binds to the default build script in the workspace root and Invoke-Build.ps1 either in the workspace root or subdirectory or in the path or the module command. .Example > New-VSCodeTask ./Scripts/Build.ps1 ./packages/InvokeBuild/Invoke-Build.ps1 This command uses relative build and engine script paths. The second may be omitted, Invoke-Build.ps1 will be discovered. But it is needed if there may be several Invoke-Build.ps1 in the workspace. #> [CmdletBinding()] param( [string]$BuildFile, [string]$InvokeBuild ) function Add-Text([string]$Text) {if ($args) {$out.Write($Text, $args)} else {$out.Write($Text)}} function Add-Line([string]$Text) {if ($args) {$out.WriteLine($Text, $args)} else {$out.WriteLine($Text)}} trap {$PSCmdlet.ThrowTerminatingError($_)} $ErrorActionPreference = 'Stop' # resolve Invoke-Build.ps1 if (!$InvokeBuild) { $InvokeBuild2 = @(Get-ChildItem . -Name -Recurse -Filter Invoke-Build.ps1) $InvokeBuild = if ($InvokeBuild2) { './{0}' -f $InvokeBuild2[0] } else { 'Invoke-Build' } } $InvokeBuild2 = if ($InvokeBuild -eq 'Invoke-Build') { 'Invoke-Build' } else { "& '{0}'" -f $InvokeBuild.Replace('\', '/').Replace("'", "''") } # get all tasks and the default task $all = & $InvokeBuild ?? -File $BuildFile $dot = if ($all['.']) {'.'} else {$all.Item(0).Name} # tasks.json header $out = New-Object System.IO.StringWriter $Header = '// Do not edit!
