# Logical Verification 2022: Installation Instructions

We have installation instructions for Windows, Linux, and macOS.

These directions are adapted from the
[leanprover-community](https://leanprover-community.github.io/get_started.html#regular-install)
web page.

<details><summary>Windows</summary>

## Windows

These instructions are also covered in a [YouTube video](https://www.youtube.com/watch?v=y3GsHIe4wZ4).
This does not include the "Install Our Logical Verification Repository" step.

### Get Lean

* Install Git for Windows: https://gitforwindows.org/. Accept all default
  answers during the installation (or, if you would like to minimize the
  installation, you may deselect all components on the "Select components"
  question).

* Start the newly installed `Git Bash` by searching for it in the Windows
  search bar.

* In Git Bash, run the command
  `curl https://raw.githubusercontent.com/leanprover/elan/master/elan-init.sh -sSf | sh`.

* Press `[Enter]` to proceed with the installation.

* Run `echo 'PATH="$HOME/.elan/bin:$PATH"' >> $HOME/.profile`.

* Close Git Bash.

### Get Python

* Download the latest version of python [here](https://www.python.org/downloads/).

* Run the downloaded file (`python-3.x.x.exe`)

* Check `Add Python 3.x to PATH`.

* Choose the default installation.

* Open Git Bash (type `git bash` in the Start Menu)

* Run `which python`
  * The expected output is something like
    `/c/Users/<user>/AppData/Local/Programs/Python/Pythonxx-xx/python`. In this
    case, proceed to the next step.
  * If it's something like
    `/c/Users/<user>/AppData/Local/Microsoft/WindowsApps/python`, then
    * Did you follow the instruction to select `Add Python 3.x to PATH` during
      the installation?
      * If not, re-run the python installer to uninstall python and try again.
    * Otherwise, you need to disable a Windows setting.
      * Type `manage app execution aliases` into the Windows search prompt
        (start menu) and open the corresponding System Settings page.
      * There should be two entries `App Installer python.exe` and `App
        Installer python3.exe`. Ensure that both of these are set to `Off`.
    * Close and reopen Git Bash and restart this step.
  * If it is any other directory, you might have an existing version of Python.
    Ask the TAs for help.
  * If you get `command not found`, you should add the Python directory to your
    path. Google how to do this, or ask the TAs.

* Run `cp "$(which python)" "$(which python)"3`. This ensures that we can use
  the command `python3` to call Python.

* Test whether everything is working by typing `python3 --version` and `pip3
  --version`. If both commands give a short output and no error, everything is
  set up correctly.
  * If `pip3 --version` doesn't give any output, run the command `python3 -m pip
    install --upgrade pip`, which should fix it.

### Configure Git

* Run `git config --global core.autocrlf input` in Git Bash.

### Install Lean Tools

* in Git Bash, run

```bash
  pip3 install mathlibtools
  ```

### Install and Configure the Editor

* Install [VSCode](https://code.visualstudio.com/).

* Launch VSCode.

* Go to View > Extensions in the menu (or press <kbd>Shift</kbd><kbd>Ctrl</kbd><kbd>X</kbd>) and search for
  `leanprover`.

* Select the `lean` extension (unique name `jroesch.lean`). There is also a
  `lean4` extension, but that one does not work for our course.

* Click "install" (in old versions of VSCode, you might need to click "reload"
  afterwards)

* Setup the default profile:

* If you're using `git bash`, press `ctrl-shift-p` to open the command
    palette, and type `Select Default Profile`, then select `git bash` from the
    menu.

* Restart VSCode.

* Verify Lean is working, for example by saving a file `test.lean` and entering
  `#eval 1+1`. A green line should appear underneath `#eval 1+1`, and hovering
  the mouse over it you should see `2` displayed.

### Install Our Logical Verification Repository

* Close VSCode.

* Open Git Bash.

* In Git Bash, use `cd` to go to the directory you want to place the project in
  (a new folder will be created for it at that location). For instance, you can
  use `cd ~/Documents` to go to your personal Documents folder.

* Run these commands in Git Bash:

```bash
  leanproject get blanchette/logical_verification_2022
  cd logical_verification_2022
  lean --make lean
  ```

The last command should produce a long list of warnings and errors which you
  can ignore.

* Launch VSCode.

* In the `File` menu, click `Open Folder`, and choose the folder
  `logical_verification_2022` (not one of its subfolders). If you used
  `~/Documents` above, it will be located in your `Documents` folder.

* In the file explorer on the left-hand side, you will find all exercises and
  homework in the `lean` folder, as we upload them.

* You can retrieve the newest exercises and homework that we upload by clicking
  the two arrows forming a circle in the bottom left corner.

## Debian/Ubuntu and Derivates

These instructions are also in a [YouTube video](https://www.youtube.com/watch?v=02ff4WrW0FU),
not including the Logical Verification repository details.

### Install Lean

* Open a terminal, enter the following command and hit enter. (This will take
  some time.)

```bash
  wget -q https://raw.githubusercontent.com/leanprover-community/mathlib-tools/master/scripts/install_debian.sh && bash install_debian.sh ; rm -f install_debian.sh && source ~/.profile
  ```

* You may have to log out and log in again to make sure that the `lean` command
  is on your `PATH`.

### Install Our Logical Verification Repository

* Use `cd` to go to the directory you want to place the project in. (A new
  folder will be created for it at that location.)

```bash
  leanproject get blanchette/logical_verification_2022
  cd logical_verification_2022
  lean --make lean
  ```

The last command should produce a long list of warnings and errors which you
  can ignore.

* Launch VSCode, either through your application menu or by typing `code`.

* On the main screen, or in the `File` menu, click `Open Folder`, and choose
  the folder `logical_verification_2022` (not one of its subfolders).

* In the file explorer on the left-hand side, you will find all exercises and
  homework in the `lean` folder, as we upload them.

* You can retrieve the newest exercises and homework that we upload by
  clicking the two arrows forming a circle in the bottom left corner.

<details><summary>macOS (M1 Macs / Apple Silicon)</summary>

## macOS (M1 Macs / Apple Silicon)

Lean is not yet supported on M1 Macs. Specifically, `elan` – which is otherwise
recommended (and installed) as part of the above instructions – will not be able
to fetch Lean binaries on these devices.

In the meantime, you can try to set up an Intel installation using Rosetta:

* [Install an Intel version of homebrew](https://stackoverflow.com/questions/64882584/how-to-run-the-homebrew-installer-under-rosetta-2-on-m1-macbook).

* Follow [the detailed Lean installation
  instructions](https://leanprover-community.github.io/install/macos_details.html),
  ensuring you use the Intel version of homebrew.

* Open a Rosetta terminal.

* Use `cd` to go to the directory you want to place the project in (a new folder
  will be created for it at that location), for example you can use
  `~/Documents`.

```bash
  leanproject get blanchette/logical_verification_2022
  cd logical_verification_2022
  lean --make lean
  ```

The last command should produce a long list of warnings and errors which you
  can ignore.

* Open VSCode again.

* In the `File` menu, click `Open`, and choose the folder
  `logical_verification_2022` (not one of its subfolders). If you used
  `~/Documents` above, it will be in the `Documents` folder.

  clicking the two arrows forming a circle in the bottom left corner.

There is a [Zulip thread](https://leanprover-community.github.io/archive/stream/113489-new-members/topic/M1.20macs.html) with some interim further
details and advice. If you have trouble, ask the TAs for help.

<details><summary>Virtual Machine (for Any Operating System)</summary>

## Virtual Machine

* These are the instructions for 2021. They need to be updated for 2022. If you
  are a student, please talk to one of the instructors before following these
  instructions.

* Download and install [VirtualBox](https://www.virtualbox.org/).
  (Other virtualization software should also work.)

* Download the virtual machine, `logical_verification_2021.ova` (3.3G), from
  [Google Drive](https://drive.google.com/file/d/1wFt7b0REC_8qqnO3CdOExi6iG6HIXZLQ/view).

SHA256:
  ```
  c0d002a3bdb4b37ec9e69f6accc2e80846e70253a3e3abe7731436b85b93a854  logical_verification_2021.ova
  ```

* Open VirtualBox.

* Import the downloaded file via `File > Import Appliance`. This requires around
  7GB of disk space.

* Start the virtual machine by selecting `logical_verification_2021` and
  clicking the `Start` button. The virtual machine is configured to use 4
  processor cores and up to 5GB of RAM. (You can edit the virtual machine to
  change these values.) It uses around 4 GB of RAM if you open all the Lean
  files in VSCode.

* Open VSCode by clicking on the blue ribbon icon on the desktop. VSCode should
  automatically open the folder `~/logical_verification_2021`. In the file
  explorer on the left-hand side, you will find all exercises and homework in
  the `lean` folder, as we upload them.

* You can retrieve the newest exercises and homework that we upload by
  clicking the two arrows forming a circle in the bottom left corner.

* If you need the password for the virtual machine at some point, it is
  `love`.
