← [README](README.md)

This file provides more technical documentation about SMAPI. If you only want to use or create
mods, this section isn't relevant to you; see the main README to use or create mods.

## Development
### Compiling from source
Using an official SMAPI release is recommended for most users.

SMAPI uses some C# 7 code, so you'll need at least
[Visual Studio 2017](https://www.visualstudio.com/vs/community/) on Windows,
[MonoDevelop 7.0](http://www.monodevelop.com/) on Linux,
[Visual Studio 2017 for Mac](https://www.visualstudio.com/vs/visual-studio-mac/), or an equivalent
IDE to compile it. It uses build configuration derived from the
[crossplatform mod config](https://github.com/Pathoschild/Stardew.ModBuildConfig#readme) to detect
your current OS automatically and load the correct references. Compile output will be placed in a
`bin` folder at the root of the git repository.

### Debugging a local build
Rebuilding the solution in debug mode will copy the SMAPI files into your game folder. Starting
the `StardewModdingAPI` project with debugging from Visual Studio (on Mac or Windows) will launch
SMAPI with the debugger attached, so you can intercept errors and step through the code being
executed. This doesn't work in MonoDevelop on Linux, unfortunately.

### Preparing a release
To prepare a crossplatform SMAPI release, you'll need to compile it on two platforms. See
[crossplatforming info](http://stardewvalleywiki.com/Modding:Creating_a_SMAPI_mod#Test_on_all_platforms)
on the wiki for the first-time setup.

1. Update the version number in `GlobalAssemblyInfo.cs` and `Constants::Version`. Make sure you use a
   [semantic version](http://semver.org). Recommended format:

   build type | format                            | example
   :--------- | :-------------------------------- | :------
   dev build  | `<version>-alpha.<timestamp>`     | `2.0-alpha.20171230`
   prerelease | `<version>-prerelease.<ID>`       | `2.0-prerelease.2`
   release    | `<version>`                       | `2.0`

2. In Windows:
   1. Rebuild the solution in _Release_ mode.
   2. Rename `bin/Packaged` to `SMAPI <version>` (e.g. `SMAPI 2.0`).
   2. Transfer the `SMAPI <version>` folder to Linux or Mac.  
      _This adds the installer executable and Windows files. We'll do the rest in Linux or Mac,
      since we need to set Unix file permissions that Windows won't save._

2. In Linux or Mac:
   1. Rebuild the solution in _Release_ mode.
   2. Copy `bin/internal/Packaged/Mono` into the `SMAPI <version>` folder.
   3. If you did everything right so far, you should have a folder like this:

      ```
      SMAPI-2.x/
         install.exe
         readme.txt
         internal/
            Mono/
               Mods/*
               Mono.Cecil.dll
               Newtonsoft.Json.dll
               StardewModdingAPI
               StardewModdingAPI.AssemblyRewriters.dll
               StardewModdingAPI.config.json
               StardewModdingAPI.exe
               StardewModdingAPI.pdb
               StardewModdingAPI.xml
               steam_appid.txt
               System.Numerics.dll
               System.Runtime.Caching.dll
               System.ValueTuple.dll
            Windows/
               Mods/*
               Mono.Cecil.dll
               Newtonsoft.Json.dll
               StardewModdingAPI.AssemblyRewriters.dll
               StardewModdingAPI.config.json
               StardewModdingAPI.exe
               StardewModdingAPI.pdb
               StardewModdingAPI.xml
               System.ValueTuple.dll
               steam_appid.txt
      ```
   4. Open a terminal in the `SMAPI <version>` folder and run `chmod 755 internal/Mono/StardewModdingAPI`.
   5. Copy & paste the `SMAPI <version>` folder as `SMAPI <version> for developers`.
   6. In the `SMAPI <version>` folder...
      * edit `internal/Mono/StardewModdingAPI.config.json` and
        `internal/Windows/StardewModdingAPI.config.json` to disable developer mode;
      * delete `internal/Windows/StardewModdingAPI.xml`.
   7. Compress the two folders into `SMAPI <version>.zip` and `SMAPI <version> for developers.zip`.

## Customisation
### Configuration file
You can customise the SMAPI behaviour by editing the `StardewModdingAPI.config.json` file in your
game folder.

Basic fields:

field             | purpose
----------------- | -------
`DeveloperMode`   | Default `false` (except in _SMAPI for developers_ releases). Whether to enable features intended for mod developers (mainly more detailed console logging).
`CheckForUpdates` | Default `true`. Whether SMAPI should check for a newer version when you load the game. If a new version is available, a small message will appear in the console. This doesn't affect the load time even if your connection is offline or slow, because it happens in the background.
`VerboseLogging`  | Default `false`. Whether SMAPI should log more information about the game context.
`ModData`         | Internal metadata about SMAPI mods. Changing this isn't recommended and may destabilise your game. See documentation in the file.

### Command-line arguments
The SMAPI installer recognises three command-line arguments:

argument | purpose
-------- | -------
`--install` | Preselects the install action, skipping the prompt asking what the user wants to do.
`--uninstall` | Preselects the uninstall action, skipping the prompt asking what the user wants to do.
`--game-path "path"` | Specifies the full path to the folder containing the Stardew Valley executable, skipping automatic detection and any prompt to choose a path. If the path is not valid, the installer displays an error.

SMAPI itself recognises two arguments, but these are intended for internal use or testing and may
change without warning.

argument | purpose
-------- | -------
`--log-path "path"` | The relative or absolute path of the log file SMAPI should write.
`--no-terminal` | SMAPI won't write anything to the console window. (Messages will still be written to the log file.)

### Compile flags
SMAPI uses a small number of conditional compilation constants, which you can set by editing the
`<DefineConstants>` element in `StardewModdingAPI.csproj`. Supported constants:

flag | purpose
---- | -------
`SMAPI_FOR_WINDOWS` | Indicates that SMAPI is being compiled on Windows for players on Windows. Set automatically in `crossplatform.targets`.
