## What is SMAPI?
|
|
**SMAPI** is an [open-source](LICENSE) modding API for [Stardew Valley](http://stardewvalley.net/)
|
|
that lets you play the game with mods. It's safely installed alongside the game's executable, and
|
|
doesn't change any of your game files. It serves five main purposes:
|
|
|
|
1. **Load mods into the game.**
|
|
_SMAPI loads mods when the game is starting up so they can interact with it. (Code mods aren't
|
|
possible without SMAPI to load them.)_
|
|
|
|
2. **Provide APIs and events for mods.**
|
|
_SMAPI provides low-level APIs and events which let mods interact with the game in ways they
|
|
otherwise couldn't._
|
|
|
|
3. **Rewrite mods for crossplatform compatibility.**
|
|
_SMAPI rewrites mods' compiled code before loading them so they work on Linux/Mac/Windows
|
|
without the mods needing to handle differences between the Linux/Mac and Windows versions of the
|
|
game._
|
|
|
|
4. **Rewrite mods to update them.**
|
|
_SMAPI detects when a mod accesses part of the game that changed in a recent update which
|
|
affects many mods, and rewrites the mod so it's compatible._
|
|
|
|
5. **Intercept errors.**
|
|
_SMAPI intercepts errors that happen in the game, displays the error details in the console
|
|
window, and in most cases automatically recovers the game. This prevents mods from accidentally
|
|
crashing the game, and makes it possible to troubleshoot errors in the game itself that would
|
|
otherwise show a generic 'program has stopped working' type of message._

## For SMAPI developers
|
|
_This section is about compiling SMAPI itself from source. If you don't know what that means, this
|
|
section isn't relevant to you; see the previous sections to use or create mods._
|
|
|
|
### 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.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.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`.
|
|
|
|
## Advanced usage
|
|
### 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.
|
|
|
|
Advanced fields (changing these isn't recommended and may destabilise your game):
|
|
|
|
field | purpose
|
|
----- | -------
|
|
`DisabledMods` | A list of mods to consider obsolete and not load.
|
|
`ModCompatibility` | A list of mod versions SMAPI should consider compatible or broken regardless of whether it detects incompatible code. This can be used to force SMAPI to load an incompatible mod, though that isn't recommended.
|
|
|
|
### 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`.
