PowerShell
==========
This repository is "Project Magrathea": Open PowerShell on GitHub, for
Linux, Windows (.NET Core and Full), and OS X. It is built using the
[.NET Command Line Interface][dotnet-cli] to support targetting every
flavor of PowerShell. It is a collaborative effort among many teams:
- Full PowerShell
- Core PowerShell
- Open Source Technology Center
- .NET Foundation
[dotnet-cli]: https://github.com/dotnet/cli

## Obtain the source code
### Setup Git
Install [Git][], the version control system.
See the [Contributing Guidelines](CONTRIBUTING.md) for more Git
information, such as our installation instructions, contributing
rules, and Git best practices.
[Git]: https://git-scm.com/documentation
### Download source code
Clone this repository. It is a "superproject" and has a number of
other repositories embedded within it as submodules. *Please* see the
contributing guidelines and learn about submodules. Not every
submodule is required on every system; see the individual build
instructions for the necessary subsets.
## Debugging
To enable debugging on Linux, follow the installation instructions for
[Experimental .NET Core Debugging in VS Code][VS Code]. You will also
want to review their [detailed instructions][vscclrdebugger].
VS Code will place a `.vscode` directory in the PowerShell folder.
This contains the `launch.json` file, which you will customize using
the instructions below. You will also be prompted to create a
`tasks.json` file.
Currently, debugging supports attaching to a currently running
powershell process. Assuming you've created a `launch.json` file
correctly, within the "configuration" section, use the below settings:
```json
"configurations": [
{
"name": "powershell",
"type": "coreclr",
"request": "attach",
"processName": "powershell"
}
]
```
VS Code will now attach to a running `powershell` process. Start
powershell, then (in VS Code) press `F5` to begin the debugger.

## PowerShell Remoting Protocol
PSRP communication is tunneled through OMI using the `omi-provider`.
> PSRP has been observed working on OS X, but the changes made to OMI to
> accomplish this are not even beta-ready and need to be done correctly. They
> exist on the `andschwa-osx` branch of the OMI repository.
PSRP support is *not* built automatically. See the detailed notes on
how to enable it.
### Running
Some initial setup on Windows is required. Open an administrative command
prompt and execute the following:
```cmd
winrm set winrm/config/Client @{AllowUnencrypted="true"}
winrm set winrm/config/Client @{TrustedHosts="*"}
```
> You can also set the `TrustedHosts` to include the target's IP address.
Then on Linux, launch `omiserver` in the debugger (after building with the
instructions above):
```sh
./psrp.sh
run
```
> The `run` command is executed inside of LLDB (the debugger) to start the
`omiserver` process.
Now in a PowerShell prompt on Windows (opened after setting the WinRM client
configurations):
```powershell
Enter-PSSession -ComputerName <IP address of Linux machine> -Credential $cred -Authentication basic
```
> The `$cred` variable can be empty; a credentials prompt will appear, enter
> any fake credentials you wish as authentication is not yet implemented.
The IP address of the Linux machine can be obtained with:
```sh
ip -f inet addr show dev eth0
```
## Detailed Build Script Notes
> This sections explains the build scripts.
The variable `$BIN` is the output directory, `bin`.
### PSRP
#### OMI
**PSRP support is not built by `./build.sh`**
To develop on the PowerShell Remoting Protocol (PSRP) for Linux, you'll need to
be able to compile OMI, which additionally requires:
```sh
sudo apt-get install libpam0g-dev libssl-dev libcurl4-openssl-dev libboost-filesystem-dev
```
Note that the OMI build steps can be done with `./omibuild.sh`.
Build OMI from source in developer mode:
```sh
cd src/omi/Unix
./configure --dev
make -j
```
#### Provider
The provider uses CMake to build, link, and register with OMI.
```sh
cd src/omi-provider
cmake .
make -j
```
The provider also maintains its own native host library to initialize the CLR,
but there are plans to refactor .NET's packaged host as a shared library.
### FullCLR PowerShell
## Running from CI server
We publish an archive with FullCLR bits on every CI build with [AppVeyor][].
* Download zip package from **artifacts** tab of the particular build.
* Unblock zip file: right-click in file explorer -> properties -> check
'Unblock' checkbox -> apply
* Extract zip file to `$bin` directory
* `Start-DevPSGithub -binDir $bin`
