-# planetwars
+# mozaic4
 
-Planetwars is a competitive programming game. You implement a bot that will be pitted against all other bots.
+Because third time's the charm!
 
-Try it out at https://planetwars.dev !
+Project layout:
-
-Current features:
-- write and publish a python bot in the demo web interface
-- develop a bot locally and publish it as a docker container
-- published bots will be ranked in the background
-
-
-## Creating a bot locally
-For development, you can play a game with a locally running bot using [`planetwars-client`](https://github.com/iasoon/planetwars.dev/tree/main/planetwars-client). \
-Once you are happy with your bot, you can publish it to the planetwars server as a docker container.
-
-1. Register your bot. In order to publish a bot version, you first have to register a bot name. You can do this by navigating to your profile after logging in (click your name in the navbar).
-2. Bake your bot into a docker container. If you'd like to test whether your container works, you can try running it using `planetwars-client` by using `docker run -it my-bot-tag` as the run command.
-3. Log in to the planetwars docker registry: `docker login registry.planetwars.dev`
-4. Tag and push your bot to `registry.planetwars.dev/my-bot-name:latest`.
-5. Your bot should be up and running now! Feel free to play a game against  it to test whether all is well. Shortly, your bot should appear in the rankings.

-## Project
-The repository contains these components:
 - `planetwars-server`: rust webserver
-- `planetwars-matchrunner`: code for running matches
+- `planetwars-matchrunner`: implements the game
-- `planetwars-rules`: implements the game rules
-- `planetwars-client`: for running your bot locally
 - `web/pw-server`: frontend
 - `web/pw-visualizer`: code for the visualizer

+# planetwars-cli
+ATTENTION: this package is currently out-of-date.
+
+Note: this project is under active development. All file and configuration formats will take some time to stabilize, so be prepared for breakage when you upgrade to a new version.
+## Building
+
+The cli comes with a local webserver for visualizing matches.
+Therefore, you'll have to build the web application first, so that it can be embedded in the binary.
+
+You will need:
+- rust
+- wasm-pack
+- npm
+
+First, build the frontend:
+```bash
+cd web/pw-frontend
+npm install
+npm run build-wasm
+npm run build
+```
+
+Then build the backend:
+```bash
+cd planetwars-cli
+cargo build --bin pwcli --release
+```
+
+You can install the binary by running
+```bash
+cargo install --path .
+```
+
+## Getting started
+First, initialize your workspace:
+```bash
+pwcli init my-planetwars-workspace
+```
+This creates all required files and directories for your planetwars workspace:
+- `pw_workspace.toml`: workspace configuration
+- `maps/`:  for storing maps
+- `matches/`: match logs will be written here
+- `bots/simplebot/` an example bot to get started 
+
+All subsequent commands should be run from the root directory of your workspace.
+
+Try playing an example match:
+```bash
+pwcli run-match hex simplebot simplebot
+```
+
+You can now watch a visualization of the match in the web interface:
+```bash
+pwcli serve
+```
+
+You can now try writing your own bot by copying the `simplebot` example. Don't forget to add it in your workspace configuration!

-# planetwars-client
-
-`planetwars-client` can be used to play a match with your bot running on your own machine.
-
-## Usage
-
-First, create a config `mybot.toml`:
-
-```toml
-# Comand to run when starting the bot.
-# Argv style also supported: ["python", "simplebot.py"]
-command = "python simplebot.py"
-
-# Directory in which to run the command.
-# It is recommended to use an absolute path here.
-working_directory = "/home/user/simplebot"
-```
-
-Then play a match:  `planetwars-client /path/to/mybot.toml opponent_name`
-
-## Building
-- Obtain rust compiler through https://rustup.rs/ or your package manager
-- Checkout this repository
-- Run `cargo install --path .` in the `planetwars-client` directory

+
+    <p>
+      Planetwars is a game of galactic conquest for busy people. Your goal is to program a bot that
+      will conquer the galaxy for you, while you take care of more important stuff.
+    </p>
+    <p>
+      In every game turn, your bot will receive a json-encoded line on stdin, describing the current
+      state of the game. Each state will hold a set of planets, and a set of spaceship fleets
+      traveling between the planets (<em>expeditions</em>).
+    </p>
+    <p>Example game state:</p>
+    <pre>{`
+  {
+    "planets": [
+      {
+        "ship_count": 2,
+        "x": -2.0,
+        "y": 0.0,
+        "owner": 1,
+        "name": "your planet"
+      },
+      {
+        "ship_count": 4,
+        "x": 2.0,
+        "y": 0.0,
+        "owner": 2,
+        "name": "enemy planet"
+      },
+      {
+        "ship_count": 2,
+        "x": 0.0,
+        "y": 2.0,
+        "owner": null,
+        "name": "neutral planet"
+      }
+    ],
+    "expeditions": [
+      {
+        "id": 169,
+        "ship_count": 8,
+        "origin": "your planet",
+        "destination": "enemy planet",
+        "owner": 1,
+        "turns_remaining": 2
+      }
+    ]
+  }
+  `}</pre>
+
+    <p>
+      The <code>owner</code> field holds a player number when the planet is held by a player, and is
+      <code>null</code> otherwise. Your bot is always referred to as player 1.<br />
+      Each turn, every player-owned planet will gain one additional ship. <br />
+      Planets will never move during the game.
+    </p>
+
+    <p>
+      Every turn, you may send out expeditions to conquer other planets. You can do this by writing
+      a json-encoded line to stdout:
+    </p>
+
+    <p>Example command:</p>
+    <pre>{`
+  {
+    "moves": [
+      {
+        "origin": "your planet",
+        "destination": "enemy planet",
+        "ship_count": 2
+      }
+    ]
+  }
+  `}
+  </pre>
+    <p>
+      All players send out their commands simultaneously, so there is no turn order. You may send as
+      many commands as you please.
+    </p>
+
+    <p>
+      The amount of turns an expedition will travel is equal to the ceiled euclidean distance
+      between its origin and destination planet.
+    </p>
+
+    <p>
+      Ships will only battle on planets. Combat resolution is simple: every ship destroys one enemy
+      ship, last man standing gets to keep the planet.
+    </p>
+
+    <p>
+      The game will end when no enemy player ships remain (neutral ships may survive), or when the
+      turn limit is reached. The default limit is 100 turns.
+    </p>
+
+    <p>
+      You can code your bot in python 3.10. You have the entire stdlib at your disposal. <br />
+      If you'd like additional libraries or a different programming language, feel free to nag the administrator.
+    </p>
+
+    <h3 class="tldr">TL;DR</h3>

-# Local development
-
-Besides using the web editor, it is also possible to develop a bot in your own development environment.
-
-Using the `planetwars-client` you can play matches remotely, with your bot running on your computer.
-This is similar to using the "Play" button in the web editor.
-
-You can then submit your bot to the server as a docker container.
-
-This way, you can author bots in any language or tool you want - as long as you can dockerize it.
-
-## Running your bot locally
-
-You can use the `planetwars-client` to play matches locally.
-
-Currently, no binaries are available, so you'll have to build the client from source.
-
-### Building the binary
-
-If you do not have a rust compiler installed already, obtain one through https://rustup.rs/.
-
-1. Clone the repository:  
-   `git clone https://github.com/iasoon/planetwars.dev.git`
-2. Build and install the client:  
-   `cargo install --path planetwars.dev/planetwars-client`
-
-### Create a bot config
-
-The bot config file specifies how to run your bot. Create a file `mybot.toml` with contents like so:
-
-```toml
-# Comand to run when starting the bot.
-# Argv style also supported: ["python", "simplebot.py"]
-command = "python simplebot.py"
-
-# Directory in which to run the command.
-# It is recommended to use an absolute path here.
-working_directory = "/home/user/simplebot"
-```
-
-### Playing a match
-
-Run `planetwars-client path/to/mybot.toml opponent_name`
-
-Try `planetwars-client --help` for more options.
-
-## Publishing your bot as a docker container
-
-Once you are happy with your bot, you can push it to the planetwars server as a docker container.
-
-First, we will containerize our bot.
-
-### Containerizing your bot
-
-Our project directory looks like this:
-
-```
-simplebot/
-├── Dockerfile
-└── simplebot.py
-```
-
-We used this basic dockerfile. You can reuse this for simple python-based bots.
-
-```Dockerfile
-FROM python:3.10.1-slim-buster
-WORKDIR /app
-COPY simplebot.py simplebot.py
-CMD python simplebot.py
-```
-
-Refer to https://docs.docker.com for guides on how to write your own dockerfile.
-
-In the directory that contains your `Dockerfile`, run the following command:
-
-```bash
-docker build -t my-bot-name .
-```
-
-If all went well, your docker daemon now holds a container tagged as `my-bot-name`.
-
-### Publishing the bot
-
-1. **Create a bot**:  
-   Before you can publish your container, you will first need to create a bot on planetwars.dev.  
-   You can create a new bot by clicking the "New bot" button on your user profile page.  
-   If you have an existing bot that you wish to overwrite, you can use that instead.
-2. **Log in to the planetwars docker registry**:  
-   `docker login registry.planetwars.dev`  
-   Authenticate using your planetwars.dev credentials.
-3. **Tag your bot**:  
-   `docker tag my-bot-name registry.planetwars.dev/my-bot-name`
-4. **Push your bot**:  
-   `docker push registry.planetwars.dev/my-bot-name`  
-   This will upload the container to planetwars.dev, and automatically create a new bot version.
-
-That was it! If all went well, you should be able to see the new version on your bot page.

-# How to play
-
-## Protocol
-
-In every game turn, your bot will receive a json-encoded line on stdin, describing the current
-state of the game. Each state will hold a set of planets, and a set of spaceship fleets
-traveling between the planets (_expeditions_).
-
-Example game state:
-
-```json
-{
-  "planets": [
-    {
-      "ship_count": 2,
-      "x": -2.0,
-      "y": 0.0,
-      "owner": 1,
-      "name": "your planet"
-    },
-    {
-      "ship_count": 4,
-      "x": 2.0,
-      "y": 0.0,
-      "owner": 2,
-      "name": "enemy planet"
-    },
-    {
-      "ship_count": 2,
-      "x": 0.0,
-      "y": 2.0,
-      "owner": null,
-      "name": "neutral planet"
-    }
-  ],
-  "expeditions": [
-    {
-      "id": 169,
-      "ship_count": 8,
-      "origin": "your planet",
-      "destination": "enemy planet",
-      "owner": 1,
-      "turns_remaining": 2
-    }
-  ]
-}
-```
-
-The `owner` field holds a player number when the planet is held by a player, and is
-`null` otherwise. Your bot is always referred to as player 1.  
-Planets will never move during the game.
-
-Every turn, you may send out expeditions to conquer other planets. You can do this by writing
-a json-encoded line to stdout:
-
-Example command:
-
-```json
-{
-  "moves": [
-    {
-      "origin": "your planet",
-      "destination": "enemy planet",
-      "ship_count": 2
-    }
-  ]
-}
-
-You can dispatch as many expeditions as you like.
-```
-
-## Rules
-
-All players send out their commands simultaneously, so there is no player order.
-
-The amount of turns an expedition will travel is equal to the ceiled euclidean distance
-between its origin and destination planet.
-
-Each turn, one additional ship will be constructed on each player-owned planet.
-Neutral planets do not construct ships.
-
-Ships will only battle on planets. Combat resolution is simple: every ship destroys one enemy
-ship, last man standing gets to keep the planet. When no player has ships remaining, the planet will turn neutral.
-
-A turn progresses as follows:
-
-1. Construct ships
-2. Dispatch expeditions
-3. Arrivals & combat resolution
-
-It is not allowed for players to abandon a planet - at least one ship should remain at all times.
-Note that you are still allowed to dispatch the full ship count you observe in the game state,
-as an additional ship will be constructed before the ships depart.
-
-The game will end when no enemy player ships remain (neutral ships may survive), or when the
-turn limit is reached. When the turn limit is hit, the game will end it a tie.
-Currently, the limit is set at 500 turns.
-
-## Writing your bot
-
-You can code a bot in python 3.10 using the [web editor](/editor). A working example bot is provided.
-If you'd like to use a different programming language, or prefer coding on your own editor,
-you can try [local development](/docs/local-development).
-
-As logging to stdout will be interpreted as commands by the game server, we suggest you log to stderr.  
-In python, you can do this using
-
-```python
-print("hello world", file=sys.stderr)
-```
-
-Output written to stderr will be displayed alongside the match replay.
-
-Feel free to launch some test matches to get the hang of it!
