 # Changelog

 Experimental changelog. Mostly based on [keepachangelog](https://keepachangelog.com/en/1.0.0/) except date format. a-c-f-r-o
-#todo .trans fix

 ## Unreleased

- More cool stuff coming soon
+## [4.1.0] - 16.04.2022
+
+### Added
+
+- NadekoBot now supports mysql, postgresql and sqlite
+  - To change the db nadeko will use, simply change the `db type` in `creds.yml`
+  - There is no migration code right now, which means that if you want to switch to another system you'll either have to manually export/import your database or start fresh
+- Medusa system
+  - A massive new feature which allows developers to create custom modules/plugins/cogs 
+  - They can be load/unloaded/updated at runtime without restarting the bot
+
+### Changed
+
+- Minor club rework
+  - Clubs names are now case sensitive (owo and OwO can be 2 different clubs)
+  - Removed discriminators
+    - Current discriminators which are greater than 1 are appended to clubnames to avoid duplicates, you can rename your club with `.clubrename` to remove it
+    - Most of the clubs with #1 discriminator no longer have it (For example MyClub#1 will now just be MyClub)
+- [dev] A lot of refactoring and slight functionality changes within Nadeko's behavior system and command handler which were required in order to support the medusa system
+
+### Removed
+
+  - Removed `.clublevelreq` command as it doesn't serve much purpose
+
+## [4.0.6] - 21.03.2022
+
+### Fixes
+
+- Fixed voice presence logging
+- Fixed .clubaccept, .clubban, .clubkick and .clubunban commands

 ## [4.0.5] - 21.03.2022

+# Creating A Medusa
+
+## Theory
+
+### Introduction
+
+Medusa system allows you to write independent medusae (known as "modules", "cogs" or "plugins" in other software) which you can then load, unload and update at will without restarting the bot.  
+  
+The system itself borrows some design from the current way Nadeko's Modules are written but mostly from never-released `Ayu.Commands` system which was designed to be used for a full Nadeko v3 rewrite. 
+
+The medusa base classes used for development are open source [here](https://gitlab.com/Kwoth/nadekobot/-/tree/v4/src/Nadeko.Medusa) in case you need reference, as there is no generated documentation at the moment.
+
+### Term list
+
+#### Medusa
+
+- The project itself which compiles to a single `.dll` (and some optional auxiliary files), it can contain multiple [Sneks](#snek), [Services](#service), and [ParamParsers](#param-parser)  
+
+#### Snek
+
+- A class which will be added as a single Module to NadekoBot on load. It also acts as a [lifecycle handler](snek-lifecycle.md) and as a singleton service with the support for initialize and cleanup.
+- It can contain a Snek (called SubSnek) but only 1 level of nesting is supported (you can only have a snek contain a subsnek, but a subsnek can't contain any other sneks)
+- Sneks can have their own prefix
+    - For example if you set this to 'test' then a command called 'cmd' will have to be invoked by using `.test cmd` instead of `.cmd` 
+
+#### Snek Command
+
+- Acts as a normal command
+- Has context injected as a first argument which controls where the command can be executed
+    - `AnyContext` the command can be executed in both DMs and Servers
+    - `GuildContext` the command can only be executed in Servers
+    - `DmContext` the command can only be executed in DMs
+- Support the usual features such as default values, leftover, params, etc.
+- It also supports dependency injection via `[inject]` attribute. These dependencies must come after the context and before any input parameters
+- Supports `ValueTask`, `Task`, `Task<T>` and `void` return types
+
+#### Param Parser
+
+- Allows custom parsing of command arguments into your own types.
+- Overriding existing parsers (for example for IGuildUser, etc...) can cause issues.
+
+#### Service
+
+- Usually not needed.
+- They are marked with a `[svc]` attribute, and offer a way to inject dependencies to different parts of your medusa. 
+- Transient and Singleton lifetimes are supported.
+
+### Localization
+
+Response and command strings can be kept in one of three different places based on whether you plan to allow support for localization
+
+option 1) `res.yml` and `cmds.yml`  
+
+If you don't plan on having your app localized, but you just *may* in the future, you should keep your strings in the `res.yml` and `cmds.yml` file the root folder of your project, and they will be automatically copied to the output whenever you build your medusa.
+
+##### Example project folder structure:
+    - uwu/
+        - uwu.csproj
+        - uwu.cs
+        - res.yml
+        - cmds.yml  
+
+##### Example output folder structure:
+    - medusae/uwu/  
+        - uwu.dll  
+        - res.yml  
+        - cmds.yml
+
+option 2) `strings` folder  
+
+If you plan on having your app localized (or want to allow your consumers to easily add languages themselves), you should keep your response strings in the `strings/res/en-us.yml` and your command strings in `strings/cmds/en-us.yml` file. This will be your base file, and from there you can make support for additional languages, for example `strings/res/ru-ru.yml` and `strings/cmds/ru-ru.yml`
+
+##### Example project folder structure:
+    - uwu/
+        - uwu.csproj
+        - uwu.cs
+        - strings/
+            - res/
+                - en-us.yml
+                - ru-ru.yml
+            - cmds/
+                - en-us.yml
+                - ru-ru.yml
+
+##### Example output folder structure:
+    - medusae/uwu/
+        - uwu.dll
+        - strings/
+            - res/
+                - en-us.yml
+                - ru-ru.yml
+            - cmds/
+                - en-us.yml
+                - ru-ru.yml
+
+option 3) In the code  
+
+If you don't want any auxiliary files, and you don't want to bother making new .yml files to keep your strings in, you can specify the command strings directly in the `[cmd]` attribute itself, and use non-localized methods for message sending in your commands.
+
+If you update your response strings .yml file(s) while the medusa is loaded and running, running `.stringsreload` will reload the responses without the need to reload the medusa or restart the bot.
+
+#### Config
+
+- Medusa config is kept in `medusae/medusa.yml` file
+- At the moment this config only keeps track of which medusae are currently loaded (they will also be always loaded at startup)
+- If a medusa is causing issues and you're unable to unload it, you can remove it from the `loaded:` list in this config file and restart the bot. It won't be loaded next time the bot is started up
+
+#### Unloadability issues  
+
+To make sure your medusa can be properly unloaded/reloaded you must:
+
+-  Make sure that none of your types and objects are referenced by the Bot or Bot's services after the DisposeAsync is called on your Snek instances. 
+
+- Make sure that all of your commands execute quickly and don't have any long running tasks, as they will hold a reference to a type from your assembly
+
+- If you are still having issues, you can always run `.meunload` followed by a bot restart, or if you want to find what is causing the medusa unloadability issues, you can check the [microsoft's assembly unloadability debugging guide](https://docs.microsoft.com/en-us/dotnet/standard/assembly/unloadability)
+
+## Practice
+
+This section will guide you through how to create a simple custom medusa. You can find the entirety of this code hosted [here](https://gitlab.com/nadeko/example_medusa)
+
+#### Prerequisite
+- [.net6 sdk](https://dotnet.microsoft.com/en-us/download) installed
+- Optional: use [vscode](https://code.visualstudio.com/download) to write code
+
+#### Guide
+
+
+- Open your favorite terminal and navigate to a folder where you will keep your project .
+
+- Create a new folder 
+    - `mkdir example_medusa`
+- Create a new .net class library
+    - `dotnet new classlib`
+- Open the current folder with your favorite editor/IDE. In this case we'll use VsCode
+    - `code .`
+- Remove the `Class1.cs` file
+- Replace the contents of the `.csproj` file with the following contents
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+    <PropertyGroup>
+        <TargetFramework>net6.0</TargetFramework>
+

+    
+    <ItemGroup>
+        <!-- Base medusa package. You MUST reference this in order to have a working medusa -->
+        <!-- Also, this package comes from MyGet, which requires you to have a NuGet.Config file next to your .csproj -->
+        <PackageReference Include="Nadeko.Medusa" Version="1.0.1">

+        <!-- Note: If you want to use NadekoBot services etc... You will have to manually clone 
+          the gitlab.com/kwoth/nadekobot repo locally and reference the NadekoBot.csproj because there is no NadekoBot package atm.
+          It is strongly recommended that you checkout a specific tag which matches your version of nadeko,
+          as there could be breaking changes even between minor versions of NadekoBot.
+          For example if you're running NadekoBot 4.1.0 locally for which you want to create a medusa for,
+          you should do "git checkout 4.1.0" in your NadekoBot solution and then reference the NadekoBot.csproj
+        -->
+    </ItemGroup>
+    
+    <!-- Copy shortcut and full strings to output (if they exist) -->
+    <ItemGroup>
+        <None Update="res.yml;cmds.yml;strings/**">
+            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
+        </None>
+    </ItemGroup>
+</Project>
+
+```
+- Create a `MySnek.cs` file and add the following contents
+```cs
+using Nadeko.Snake;
+using NadekoBot;
+using Discord;
+
+public sealed class MySnek : Snek
+{
+    [cmd]
+    public async Task Hello(AnyContext ctx)
+    {
+        await ctx.Channel.SendMessageAsync($"Hello everyone!");
+    }
+
+    [cmd]
+    public async Task Hello(AnyContext ctx, IUser target)
+    {
+        await ctx.ConfirmLocalizedAsync("hello", target);
+    }
+}
+```
+- Create `res.yml` and `cmds.yml` files with the following contents
+`res.yml`
+```yml
+medusa.description: "This is my medusa's description"
+hello: "Hello {0}, from res.yml!"
+```
+
+`cmds.yml`
+```yml
+hello: 
+  desc: "This is a basic hello command"
+  args:
+    - ""
+    - "@Someone"
+```
+
+- Add `NuGet.Config` file which will let you use the base Nadeko.Medusa package. This file should always look like this and you shouldn't change it
+
+```xml
+<configuration>
+    <packageSources>
+        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
+        <add key="nadeko.bot" value="https://www.myget.org/F/nadeko/api/v3/index.json" protocolVersion="3" />
+    </packageSources>
+</configuration>
+```
+
+### Build it
+
+- Build your Medusa into a dll that Nadeko can load. In your terminal, type:
+    - `dotnet publish -o bin/medusae/example_medusa /p:DebugType=embedded`
+
+- Done. You can now try it out in action.
+
+### Try it out
+
+- Copy the `bin/medusae/example_medusa` folder into your NadekoBot's `data/medusae/` folder. (Nadeko version 4.1.0+)
+
+- Load it with `.meload example_medusa`
+
+- In the channel your bot can see, run the following commands to try it out
+    - `.hello` and
+    - `.hello @<someone>`
+
+- Check its information with
+    - `.meinfo example_medusa`
+
+- Unload it
+    - `.meunload example_medusa`
+
+- Congrats! You've just made your first medusa!

+## Getting Started
+
+### What is the Medusa system?
+
+- It is a dynamic module/plugin/cog system for NadekoBot introduced in **NadekoBot 4.1.0**  
+
+- Allows developers to add custom functionality to Nadeko without modifying the original code  
+
+- Allows for those custom features to be updated during bot runtime (if properly written), without the need for bot restart.
+
+- They are added to `data/medusae` folder and are loaded, unloaded and handled through discord commands.  
+    - `.meload` Loads the specified medusa (see `.h .meload`)
+    - `.meunload` Unloads the specified medusa (see `.h .meunload`)
+    - `.meinfo` Checks medusae information (see `.h .meinfo`)
+    - `.melist` Lists the available medusae (see `.h .melist`)
+
+### How to make one?
+
+Medusae are written in [C#](https://docs.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/) programming language, so you will need at least low-intermediate knowledge of it in order to make a useful Medusa.
+
+Follow the [creating a medusa guide](creating-a-medusa.md)
+
+### Where to get medusae other people made?
+
+⚠ *It is EXTREMELY, and I repeat **EXTREMELY** dangerous to run medusae of strangers or people you don't FULLY trust.* ⚠  
+⚠ *It can not only lead to your bot being stolen, but it also puts your entire computer and personal files in jeopardy.* ⚠
+
+**It is strongly recommended to run only the medusae you yourself wrote, and only on a hosted VPS or dedicated server which ONLY hosts your bot, to minimize the potential damage caused by bad actors.**
+
+No easy way at the moment, except asking in the `#dev-and-modding` chat in [#NadekoLog server][https://discord.nadeko.bot]

+# Snek Lifecycle  
+
+*You can override several methods to hook into command handler's lifecycle.  
+These methods start with `Exec*`*
+
+
+- `ExecOnMessageAsync` runs first right after any message was received  
+- `ExecInputTransformAsync` runs after ExecOnMessageAsync and allows you to transform the message content before the bot looks for the matching command  
+- `ExecPreCommandAsync` runs after a command was found but not executed, allowing you to potentially prevent command execution  
+- `ExecPostCommandAsync` runs if the command was successfully executed  
+- `ExecOnNoCommandAsync` runs instead of ExecPostCommandAsync if no command was found for a message  
+
+
+*Besides that, sneks have 2 methods with which you can initialize and cleanup your snek*  
+
+
+- `InitializeAsync` Runs when the medusa which contains this snek is being loaded  
+- `DisposeAsync` Runs when the medusa which contains this snek is being unloaded
