v0.9.0: Merge pull request #442 from PowerShell/release/0.9.0

New PowerShell code formatter

We've added a formatter for PowerShell code which allows you to format an
entire file or a selection within a file. You can access this formatter by
running VS Code's Format Document and Format Selection commands inside
of a PowerShell file.

You can configure code formatting with the following settings:

• powershell.codeFormatting.openBraceOnSameLine - Places open brace on the
  same line as its associated statement. Default is true.
• powershell.codeFormatting.newLineAfterOpenBrace - Ensures that a new line
  occurs after an open brace (unless in a pipeline statement on the same line).
  Default is true
• editor.tabSize - Specifies the indentation width for code blocks. This
  is a VS Code setting but it is respected by the code formatter.
• editor.formatOnSave - If true, automatically formats when they are saved.
  This is a VS Code setting and may also affect non-PowerShell files.

Please note that this is only a first pass at PowerShell code formatting, it
may not format your code perfectly in all cases. If you run into any issues,
please file an issue
and give us your feedback!

Streamlined debugging experience - launch.json is now optional!

NOTE: This improvement depends on VS Code 1.9.0 which is due for release
early February! However, you can try it out right now with the VS Code Insiders
release.

Thanks to a new improvement in VS Code's debugging APIs, we are now able to
launch the PowerShell debugger on a script file without the need for a launch.json
file. You can even debug individual PowerShell scripts without opening a
workspace folder! Don't worry, you can still use a launch.json file to configure
specific debugging scenarios.

We've also made debugger startup much more reliable. You will no longer see the
dreaded "Debug adapter terminated unexpectedly" message when you try to launch
the debugger while the language server is still starting up.

Support for debugging remote and attached runspaces

We now support remote PowerShell sessions via the Enter-PSSession
cmdlet. This cmdlet allows you to create a PowerShell session on another machine
so that you can run commands or debug scripts there. The full debugging
experience works with these remote sessions on PowerShell 4 and above, allowing
you to set breakpoints and see remote files be opened locally when those breakpoints
are hit.

For PowerShell 5 and above, we also support attaching to local and remote PowerShell
host processes using the Enter-PSHostProcess
and Debug-Runspace
cmdlets. This allows you to jump into another process and then debug a script that
is already running in one of the runspaces in that process. The debugger will break
execution of the running script and then the associated script file will be opened
in the editor so that you can set breakpoints and step through its execution.

We've also added a new launch.json configuration for debugging PowerShell host processes:

When launched, the default "attach" configuration will prompt you with a list of
PowerShell host processes on the local machine so that you can easily select one
to be debugged:

You can also edit the launch configuration to hardcode the launch parameters, even
setting a remote machine to connect to before attaching to the remote process:

        {
            "type": "PowerShell",
            "request": "attach",
            "name": "PowerShell Attach to Host Process",
            "computerName": "my-remote-machine",
            "processId": "12345",
            "runspaceId": 1
        }

Please note that we currently do not yet support initiating remote sessions from Linux
or macOS. This will be supported in an upcoming release.

Initial support for remote file opening using psedit

Another nice improvement is that we now support the psedit command in remote and
attached sessions. This command allows you to open a file in a local or remote session
so that you can set breakpoints in it using the UI before launching it. For now these
remotely-opened files will not be saved back to the remote session when you edit and
save them. We plan to add this capability in the next feature update.

New "interactive session" debugging mode

You can now create a new launch configuration which drops you directly into the
debug console so that you can debug your scripts and modules however you wish.
You can call Set-PSBreakpoint to set any type of breakpoint and then invoke your
code through the console to see those breakpoints get hit. This mode can also be
useful for debugging remote sessions.

Please note that this is NOT a replacement for a true interactive console experience.
We've added this debugging configuration to enable a few other debugging scenarios, like
debugging PowerShell modules, while we work on a true interactive console experience using
VS Code's Terminal interface.

New document symbol support for PSD1 files

We've extended our document symbol support to .psd1 files to make it really easy to
navigate through them. When you have a .psd1 file open, run the Go to Symbol in File...
command (Ctrl + Shift + O) and you'll see this popup:

You can type a symbol name or navigate using your arrow keys. Once you select one of the
symbol names, the editor pane will jump directly to that line.

Other fixes and improvements

• Added a new Open Examples Folder command to easily open the extension's
  example script folder.
• Added a new setting powershell.developer.powerShellExeIsWindowsDevBuild
  which, when true, indicates that the powerShellExePath points to a Windows
  PowerShell development build.
• Fixed #395:
  Quick Fix for PSAvoidUsingAliases rule replaces the entire command
• Fixed #396:
  Extension commands loaded in PowerShell profile are not being registered
• Fixed #391:
  DSC IntelliSense can cause the language server to crash
• Fixed #400:
  Language server can crash when selecting PSScriptAnalyzer rules
• Fixed #408:
  Quick fix requests meant for other extensions crash the language server
• Fixed #401:
  Extension startup should indicate if the current PowerShell version is unsupported
• Fixed #314:
  Errors/Warnings still show up in Problems window when file is closed
• Fixed #388:
  Syntax errors are not reported when powershell.scriptAnalysis.enable is set to false

v0.8.0

Improved PowerShell session management

It's now much easier to manage the active PowerShell session. We've added a
new item to the status bar to indicate the state of the session and the version
of PowerShell you're using:

When this status item is clicked, a new menu appears to give you some session
management options:

You can restart the active session, switch between 32-bit and 64-bit PowerShell on
Windows or switch to another PowerShell process (like a 6.0 alpha build) that
you've configured with the powershell.developer.powerShellExePath.

We've also improved the overall experience of loading and using the extension:

• It will prompt to restart the PowerShell session if it crashes for any reason
• It will also prompt to restart the session if you change any relevant PowerShell
  configuration setting like the aforementioned powershell.developer.powerShellExePath.
• You can easily access the logs of the current session by running the command
  Open PowerShell Extension Logs Folder.

Create new modules with Plaster

In this release we've added integration with the Plaster
module to provide a Create New Project from Plaster Template command. This command will
walk you through the experience of selecting a template and filling in all of
the project details:

We include one basic project template by default and will add more in the very
near future. However, you won't need to update the PowerShell extension to get these
new templates, they will appear when you install an update to the Plaster module from
the PowerShell Gallery.

Check out Plaster's documentation
for more details on how it can be used and how you can create your own templates.

New "quick fix" actions for PSScriptAnalyzer rules

The PowerShell extension now uses any "suggested corrections" which are returned with
a rule violation in your script file to provide a "quick fix" option for the affected
section of code. For example, when the PSAvoidUsingCmdletAliases rule finds the use
of a non-whitelisted alias, you will see a light bulb icon that gives the option to
change to the full name (right click or Ctrl+. on the marker):

If you'd like to see more quick fixes for PowerShell code, head over to the
PSScriptAnalyzer GitHub page and
get involved!

Easily enable and disable PSScriptAnalyzer rules

Another improvement related to PSScriptAnalyzer is the ability to change the active
PSScriptAnalyzer rules in the current editing session using a helpful selection menu:

You can enable and disable active rules by running the Select PSScriptAnalyzer Rules
command. For now this only changes the active session but in a future release we will
modify your PSScriptAnalyzer settings file so that the changes are persisted to future
editing sessions.

New "hit count" breakpoints in the debugger

When debugging PowerShell scripts you can now set "hit count" breakpoints which
cause the debugger to stop only after the breakpoint has been encountered a specified
number of times.

Other fixes and improvements

• We now provide snippets for the launch.json configuration file which make it easier
  to add new PowerShell debugging configurations for your project.
• In PowerShell launch.json configurations, the program parameter has now been
  renamed to script. Configurations still using program will continue to work.
• Fixed #353: Cannot start PowerShell debugger on Windows when offline
• Fixed #217: PowerShell output window should be shown when F8 is pressed
• Fixed #292: Check for Homebrew's OpenSSL libraries correctly on macOS
• Fixed #384: PowerShell snippets broken in VS Code 1.8.0

v0.7.2

• Fixed #243: Debug adapter process has terminated unexpectedly
• Fixed #264: Add check for OpenSSL on OS X before starting the language service
• Fixed #271: PSScriptAnalyzer settings path isn't being passed along
• Fixed #273: Debugger crashes after multiple runs
• Fixed #274: Extension crashes on Ctrl+Hover

v0.7.1

• "Auto" variable scope in debugger UI now expands by default
• Fixed #244: Extension fails to load if username contains spaces
• Fixed #246: Restore default PSScriptAnalyzer ruleset
• Fixed #248: Extension fails to load on Windows 7 with PowerShell v3

v0.6.0

Added a new cross-editor extensibility model

• We've added a new extensibility model which allows you to write PowerShell
  code to add new functionality to Visual Studio Code and other editors with
  a single API. If you've used $psISE in the PowerShell ISE, you'll feel
  right at home with $psEditor. Check out the documentation
  for more details!

Support for user and system-wide profiles

• We've now introduced the $profile variable which contains the expected
  properties that you normally see in powershell.exe and powershell_ise.exe:
  • AllUsersAllHosts
  • AllUsersCurrentHost
  • CurrentUserAllHosts
  • CurrentUserCurrentHost
• In Visual Studio Code the profile name is Microsoft.VSCode_profile.ps1.
• $host.Name now returns "Visual Studio Code Host" and $host.Version returns
  the version of the PowerShell extension that is being used.

Other improvements

• IntelliSense for static methods and properties now works correctly. If you
  type :: after a type such as [System.Guid] you will now get the correct
  completion results. This also works if you press Ctrl+Space after the ::
  characters.
• $env variables now have IntelliSense complete correctly.
• Added support for new VSCode command Debug: Start Without Debugging. Shortcut
  for this command is Ctrl+F5.
• Changed the keyboard shortcut for PowerShell: Expand Alias from Ctrl+F5 to Ctrl+Alt+e.
• Added support for specifying a PSScriptAnalyzer settings file by
  providing a full path in your User Settings for the key powershell.scriptAnalysis.settingsPath.
  You can also configure the same setting in your project's .vscode\settings.json
  file to contain a workspace-relative path. If present, this workspace-level setting
  overrides the one in your User Settings file. See the extension's examples\.vscode\settings.json
  file for an example.
• The debug adapter now does not crash when you attempt to add breakpoints
  for files that have been moved or don't exist.
• Fixed an issue preventing output from being written in the debugger if you
  don't set a breakpoint before running a script.

New configuration settings

• powershell.scriptAnalysis.settingsPath: Specifies the path to a PowerShell Script Analyzer settings file. Use either an absolute path (to override the default settings for all projects) or use a path relative to your workspace.

v0.5.0

Support for PowerShell v3 and v4

• Support for PowerShell v3 and v4 is now complete! Note that for this release,
  Script Analyzer support has been disabled for PS v3 and v4 until we implement
  a better strategy for integrating it as a module dependency

Debugging improvements

• Added support for command breakpoints.

  Hover over the Debug workspace's 'Breakpoints' list header and click the 'Add'
  button then type a command name (like Write-Output) in the new text box that
  appears in the list.

• Added support for conditional breakpoints.

  Right click in the breakpoint margin to the left of the code editor and click
  'Add conditional breakpoint' then enter a PowerShell expression in the text box
  that appears in the editor.

Other improvements

• Added a preview of a possible project template for PowerShell Gallery modules in
  the examples folder. Includes a PSake build script with Pester test, clean,
  build, and publish tasks. See the examples\README.md file for instructions.
  Check it out and give your feedback on GitHub!
• using 'module' now resolves relative paths correctly, removing a syntax error that
  previously appeared when relative paths were used
• Calling Read-Host -AsSecureString or Get-Credential from the console now shows an
  appropriate "not supported" error message instead of crashing the language service.
  Support for these commands will be added in a later release.

New configuration settings

• powershell.useX86Host: If true, causes the 32-bit language service to be used on 64-bit Windows. On 32-bit Windows this setting has no effect.

v0.4.1

• Updated PSScriptAnalyzer 1.4.0 for improved rule marker extents
• Added example Pester task for running tests in the examples folder
• Fixed #94: Scripts fail to launch in the debugger if the working directory path contains spaces

v0.4.0

Debugging improvements

@rkeithhill spent a lot of time polishing the script debugging experience for this release:

• You can now pass arguments to scripts in the debugger with the args parameter in launch.json
• You can also run your script with the 32-bit debugger by changing the type parameter in launch.json to "PowerShell x86" (also thanks to @adamdriscoll!)
• The new default PowerShell debugger configuration now launches the active file in the editor
• You can also set the working directory where the script is run by setting the cwd parameter in launch.json to an absolute path. If you need a workspace relative path, use ${workspaceRoot} to create an absolute path e.g. "${workspaceRoot}/modules/foo.psm1".

We recommend deleting any existing launch.json file you're using so that a new one will
be generated with the new defaults.

Console improvements

• Improved PowerShell console output formatting and performance
  • The console prompt is now displayed after a command is executed
  • Command execution errors are now displayed correctly in more cases
  • Console output now wraps at 120 characters instead of 80 characters
• Added choice and input prompt support
  • When executing code using the 'Run Selection' command, choice and input prompts appear as VS Code UI popups
  • When executing code in the debugger, choice and input prompts appear in the Debug Console

New commands

• "Find/Install PowerShell modules from the gallery" (Ctrl+K Ctrl+F): Enables you to find and install modules from the PowerShell Gallery (thanks @dfinke!)
• "Open current file in PowerShell ISE" (Ctrl+Shift+i): Opens the current file in the PowerShell ISE (thanks @janegilring!)

Editor improvements

• Path auto-completion lists show just the current directory's contents instead of the full path (which had resulted in clipped text)
• Parameter auto-completion lists are now sorted in the same order as they are in PowerShell ISE where command-specific parameters preceed the common parameters
• Parameter auto-completion lists show the parameter type
• Command auto-completion lists show the resolved command for aliases and the path for executables
• Many improvements to the PowerShell snippets, more clearly separating functional and example snippets (all of the latter are prefixed with ex-)
• Added some additional example script files in the examples folder

New configuration settings

• powershell.developer.editorServicesLogLevel: configures the logging verbosity for PowerShell Editor Services. The default log level will now write less logs, improving overall performance

v0.2.0

• (Experimental) Added a new "Run selection" (F8) command which executes the current code selection and displays the output
• Added a new online help command! Press Ctrl+F1 to get help for the symbol under the cursor.
• Enabled PowerShell language features for untitled and in-memory (e.g. in Git diff viewer) PowerShell files
• Added powershell.scriptAnalysis.enable configuration variable to allow disabling script analysis for performance (issue #11)
• Fixed issue where user's custom PowerShell snippets did not show up
• Fixed high CPU usage when completing or hovering over an application path

v0.1.0

Initial release with the following features:

• Syntax highlighting
• Code snippets
• IntelliSense for cmdlets and more
• Rule-based analysis provided by PowerShell Script Analyzer
• Go to Definition of cmdlets and variables
• Find References of cmdlets and variables
• Document and workspace symbol discovery
• Local script debugging and basic interactive console support
