# SMAPI
|
|
## 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`.
|
|
|
|
|
|
# SMAPI web services
|
|
## Overview
|
|
The `StardewModdingAPI.Web` project provides an API and web UI hosted at `*.smapi.io`.
|
|
|
|
### Log parser
|
|
The log parser provides a web UI for uploading, parsing, and sharing SMAPI logs. The logs are
|
|
persisted in a compressed form to Pastebin.
|
|
|
|
The log parser lives at https://log.smapi.io.
|
|
|
|
### Mods API
|
|
The mods API provides version info for mods hosted by Chucklefish, GitHub, or Nexus Mods. It's used
|
|
by SMAPI to perform update checks. The `{version}` URL token is the version of SMAPI making the
|
|
request; it doesn't do anything currently, but lets us version breaking changes if needed.
|
|
|
|
Each mod is identified by a repository key and unique identifier (like `nexus:541`). The following
|
|
repositories are supported:
|
|
|
|
key | repository
|
|
------------- | ----------
|
|
`chucklefish` | A mod page on the [Chucklefish mod site](https://community.playstarbound.com/resources/categories/22), identified by the mod ID in the page URL.
|
|
`github` | A repository on [GitHub](https://github.com), identified by its owner and repository name (like `Zoryn4163/SMAPI-Mods`). This checks the version of the latest repository release.
|
|
`nexus` | A mod page on [Nexus Mods](https://www.nexusmods.com/stardewvalley), identified by the mod ID in the page URL.
|
|
|
|
|
|
The API accepts either `GET` or `POST` for convenience:
|
|
> ```
|
|
>GET https://api.smapi.io/v2.0/mods?modKeys=nexus:541,chucklefish:4228
|
|
>```
|
|
|
|
>```
|
|
>POST https://api.smapi.io/v2.0/mods
|
|
>{
|
|
> "ModKeys": [ "nexus:541", "chucklefish:4228" ]
|
|
>}
|
|
>```
|
|
|
|
It returns a response like this:
|
|
>```
|
|
>{
|
|
> "chucklefish:4228": {
|
|
> "name": "Entoarox Framework",
|
|
> "version": "1.8.0",
|
|
> "url": "https://community.playstarbound.com/resources/4228"
|
|
> },
|
|
> "nexus:541": {
|
|
> "name": "Lookup Anything",
|
|
> "version": "1.16",
|
|
> "url": "http://www.nexusmods.com/stardewvalley/mods/541"
|
|
> }
|
|
>}
|
|
>```
|
|
|
|
## Development
|
|
### Local development
|
|
`StardewModdingAPI.Web` is a regular ASP.NET MVC Core app, so you can just launch it from within
|
|
Visual Studio to run a local version.
|
|
|
|
There are two differences when it's run locally: all endpoints use HTTP instead of HTTPS, and the
|
|
subdomain portion becomes a route (e.g. `log.smapi.io` → `localhost:59482/log`).
|
|
|
|
Before running it locally, you need to enter your credentials in the `appsettings.Development.json`
|
|
file. See the next section for a description of each setting. This file is listed in `.gitignore`
|
|
to prevent accidentally committing credentials.
|
|
|
|
### Deploying to Amazon Beanstalk
|
|
The app can be deployed to a standard Amazon Beanstalk IIS environment. When creating the
|
|
environment, make sure to specify the following environment properties:
|
|
|
|
property name | description
|
|
------------------------------- | -----------------
|
|
`LogParser:PastebinDevKey` | The [Pastebin developer key](https://pastebin.com/api#1) used to authenticate with the Pastebin API.
|
|
`LogParser:PastebinUserKey` | The [Pastebin user key](https://pastebin.com/api#8) used to authenticate with the Pastebin API. Can be left blank to post anonymously.
|
|
`LogParser:SectionUrl` | The root URL of the log page, like `https://log.smapi.io/`.
|
|
`ModUpdateCheck:GitHubPassword` | The password with which to authenticate to GitHub when fetching release info.
|
|
`ModUpdateCheck:GitHubUsername` | The username with which to authenticate to GitHub when fetching release info.
|
|
|
|
## Mod build config package
|
|
### Overview
|
|
The mod build config package is a NuGet package that mods reference to automatically set up
|
|
references, configure the build, and add analyzers specific to Stardew Valley mods.
|
|
|
|
This involves three projects:
|
|
|
|
project | purpose
|
|
------------------------------------------------- | ----------------
|
|
`StardewModdingAPI.ModBuildConfig` | Configures the build (references, deploying the mod files, setting up debugging, etc).
|
|
`StardewModdingAPI.ModBuildConfig.Analyzer` | Adds C# analyzers which show code warnings in Visual Studio.
|
|
`StardewModdingAPI.ModBuildConfig.Analyzer.Tests` | Unit tests for the C# analyzers.
|
|
|
|
When the projects are built, the relevant files are copied into `bin/Pathoschild.Stardew.ModBuildConfig`.
|
|
|
|
### Preparing a build
|
|
To prepare a build of the NuGet package:
|
|
1. Install the [NuGet CLI](https://docs.microsoft.com/en-us/nuget/install-nuget-client-tools#nugetexe-cli).
|
|
1. Change the version and release notes in `package.nuspec`.
|
|
2. Rebuild the solution in _Release_ mode.
|
|
3. Open a terminal in the `bin/Pathoschild.Stardew.ModBuildConfig` package and run this command:
|
|
```bash
|
|
nuget.exe pack
|
|
```
|
|
|
|
That will create a `Pathoschild.Stardew.ModBuildConfig-<version>.nupkg` file in the same directory
|
|
which can be uploaded to NuGet or referenced directly.
