A game I'm working. It's a weird one. |
||||
# About Turing's Tarpit |
||||
|
||||
Right now I've got a command that watches your files for changes, and runs a build command. It's |
||||
entirely overengineered for this purpose, but it has what I'll need later. To build it do this: |
||||
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 |
||||
|
||||
> __WARNING__ These instructions are off the top of my head right now so they're probably wrong. I |
||||
> need to do a clean build in a fresh VM. |
||||
|
||||
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 |
||||
./scripts/reset_build.ps1 |
||||
meson compile -C builddir |
||||
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 |
||||
``` |
||||
|
||||
If you get a bad compile because of libgit2's `src/util/process.h` then do this: |
||||
That should setup your meson build with everything you need, so now you run it: |
||||
|
||||
```shell |
||||
cp patches/process.h subprojects/libgit2/src/util/ |
||||
meson compile -C builddir |
||||
``` |
||||
|
||||
I don't know why it fails at this, and only on Windows but I've talked to them repeatedly and it's |
||||
mostly "works for me" responses. I also can't figure out how Meson exactly applies patches. I've |
||||
generated every possible patch I can and Meson just can't apply them. |
||||
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. |
||||
|
||||
|
||||
Once it's running, we have even more annoying BS to deal with, and that's because Meson doesn't |
||||
actually statically compile efsw or libgit2. Even though I said `--default-librart=static --prefer-static` in the setup it just ignores that and makes DLLs. The "fix" for this asinine stupidity is this: |
||||
Then hang out for a while and it should build. You can then do your first run. First, run the |
||||
tests: |
||||
|
||||
```shell |
||||
meson devenv -C builddir |
||||
cd .. |
||||
cp builddir/watchgit . |
||||
./watchgit . "meson compile -C builddir |
||||
.\builddir\runtests |
||||
``` |
||||
|
||||
Do all that garbage and yay, this little program runs. Finally. |
||||
If those run then try to run the game on its own code: |
||||
|
||||
## Future Changes |
||||
```shell |
||||
cp .\builddir\escape_turings_tarpit.exe . ; .\escape_turings_tarpit.exe .\ "meson compile -C builddir" |
||||
``` |
||||
|
||||
1. If I can't figure out why libgit2 has compilation errors in `src/util/process.h` then I may just rip it out and just shell out to `git` directly. |
||||
2. Ultimately I can jsut use efsw to watch the directory for all changes, but I wanted to only focus on what's in git. Oh well. |
||||
3. I also have to find out why efsw and libgit2 refuse to compile statically. Once I do that I can static compile `watchgit` and then work on the next part of the game. |
||||
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. |
