# About Turing's Tarpit

This is a game for programmers. The eventual goal is to make a small game that makes programmer
development live streams more exciting, but also makes it fun to try to keep your code bug free.

## How It Works

0. You start with 100 Hit Points (HP).
1.  _Turing's Tarpit (TT)_ watches your git repo.
2. If you save any files in your git then TT will run your build.
3. It then uses a regex to detect errors, warnings, and notes from your compiler.
4. Every error is 4 HP of damage.  Warnings and Notes are 1 HP.
5. If you successfully build with no errors then you get 10% HP back (healed).
6. It keeps track of your rounds, and your longest streak.  A streak is how many builds have run without producing an error.

Eventually this will become more complex as I add in a few more mechanics, but this is the general
game loop.  Some of the ideas for future mechanics:

1. I have a real trash Brainfuck compiler.  I want to have that in there somewhere.
2. I like the way Shotgun Roulette works where you get some items per round and can use them to gain
   an advantage.
3. I want streaks to be some kind of reward, either you just get some healing after a certain
   number, or you can "cash them in" for a special item.
4. It needs to detect when you don't make enough changes to be worth it, but I might try to punish you if you just change a file's timestamp.
5. Running your unit tests as well to analyze the TAP output and punish you for test failures.

## Platforms

Currently this only works on Windows but there's nothing in this that will stop it from working
anywhere else. It uses FTXUI to make a TUI so that means it's very portable. I just haven't spent
the time to try to port it yet.

It's also only been test with GCC and C++. I'm betting the regex will be crazy wrong for any other
language. _BTW, where's the TAP output for compilers?_

## Compiling Setup

To build this you'll need to install [winlibs](https://winlibs.com/) and [meson](https://mesonbuild.com/) but I believe my build process downloads everything else.

If you want to get setup quickly with a C/C++ build environment then you can use my installer scripts. Start a _NORMAL_ user PowerShell to run this. If you're walking around the internet as a raw _Administrator_ user then you might as well just inject ebola infected blood straight into your eye you idiot. No, UAC will not save you. Listen to Zed.

Now, in your _NORMAL_ user PowerShell do this:

```shell
irm https://learncodethehardway.com/setup/base.ps1 -outfile base.ps1
powershell -executionpolicy bypass .\base.ps1
```

Do not _go anywhere_. You have to enter in passwords for your _Administrator_ user.  You do have a
second user that's an administrator right?  Seriously, what's your problem. Do you just like having
your neighbor install a RAT tool to spy on you? Make two accounts already.

Now that you have this you can install the compiler tools:

```shell
irm https://learncodethehardway.com/setup/cpp.ps1 -outfile cpp.ps1
powershell -executionpolicy bypass .\cpp.ps1
```

For a bit of extra nice things, run my `extras.ps1` too:


```shell
irm https://learncodethehardway.com/setup/extras.ps1 -outfile extras.ps1
powershell -executionpolicy bypass .\extras.ps1
```

## Building

Once you have all of that you should be able to check out the code from this git:

```shell
git clone https://git.learnjsthehardway.com/learn-code-the-hard-way/turings-tarpit.git
```

Then change into the directory and run my setup script:

```shell
powershell -executionpolicy bypass .\scripts\reset_build.ps1
```

That should setup your meson build with everything you need, so now you run it:

```shell
meson compile -C builddir
```

One thing I ran into is that there's an error in `libgit2`'s code.  If you get a build error in
`utils\process.h` then run this command to fix it:

```shell
cp .\patches\process.h .\subprojects\libgit2-1.8.1\src\util\process.h
```

The next dumb as hell thing is even though I've told `meson` to build a static binary it refuses.
You have to copy a couple .dll files to your local directory for the easiest way to play with it:

```shell
cp .\builddir\subprojects\libgit2-1.8.1\*.dll .
cp .\builddir\subprojects\efsw\*.dll .
ls *.dll
```

You should then see the `libefsw.dll` and `liblibgit2package.dll` files in the local directory which
will let you run the `escape_turings_tarpit.exe` game locally.

> __WARNING__ The reason you're copying all these files to the local directory is so you can run the
> game and the DLLs but _also_ run the build on the code.  Windows locks executables when they're
> active, so when you build `builddir/escape_turings_tarpit.exe` it'll fail if you're also running
> it.  Copy it all up and then you can run builds in the game while you work on the game.


Then hang out for a while and it should build. You can then do your first run.  First, run the
tests:

```shell
.\builddir\runtests
```

If those run then try to run the game on its own code:

```shell
cp .\builddir\escape_turings_tarpit.exe . ;  .\escape_turings_tarpit.exe .\ "meson compile -C builddir"
```

Now it's playing, so all you have to do is open one of the .cpp files, make a mistake, save it, and
watch the game play.
