← [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. This document is about SMAPI itself; see also [mod build package](mod-package.md) and [web services](web.md). # Contents * [Customisation](#customisation) * [Configuration file](#configuration-file) * [Command-line arguments](#command-line-arguments) * [Compile flags](#compile-flags) * [For SMAPI developers](#for-smapi-developers) * [Compiling from source](#compiling-from-source) * [Debugging a local build](#debugging-a-local-build) * [Preparing a release](#preparing-a-release) * [Using a custom Harmony build](#using-a-custom-harmony-build) * [Release notes](#release-notes) ## Customisation ### Configuration file You can customise some SMAPI behaviour by editing the `smapi-internal/config.json` file in your game folder. See documentation in the file for more info. ### 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 **on Windows only**, but these are intended for internal use or testing and may change without warning. On Linux/macOS, see _environment variables_ below. argument | purpose -------- | ------- `--no-terminal` | SMAPI won't write anything to the console window. (Messages will still be written to the log file.) `--mods-path` | The path to search for mods, if not the standard `Mods` folder. This can be a path relative to the game folder (like `--mods-path "Mods (test)"`) or an absolute path. ### Environment variables The above SMAPI arguments don't work on Linux/macOS due to the way the game launcher works. You can set temporary environment variables instead. For example: > SMAPI_MODS_PATH="Mods (multiplayer)" /path/to/StardewValley environment variable | purpose -------------------- | ------- `SMAPI_NO_TERMINAL` | Equivalent to `--no-terminal` above. `SMAPI_MODS_PATH` | Equivalent to `--mods-path` above. ### Compile flags SMAPI uses a small number of conditional compilation constants, which you can set by editing the `` element in `SMAPI.csproj`. Supported constants: flag | purpose ---- | ------- `SMAPI_FOR_WINDOWS` | Whether SMAPI is being compiled for Windows; if not set, the code assumes Linux/macOS. Set automatically in `common.targets`. `SMAPI_FOR_WINDOWS_64BIT_HACK` | Whether SMAPI is being [compiled for Windows with a 64-bit Linux version of the game](https://github.com/Pathoschild/SMAPI/issues/767). This is highly specialized and shouldn't be used in most cases. False by default. `SMAPI_FOR_XNA` | Whether SMAPI is being compiled for XNA Framework; if not set, the code assumes MonoGame. Set automatically in `common.targets` with the same value as `SMAPI_FOR_WINDOWS` (unless `SMAPI_FOR_WINDOWS_64BIT_HACK` is set). `HARMONY_2` | Whether to enable experimental Harmony 2.0 support and rewrite existing Harmony 1._x_ mods for compatibility. Note that you need to replace `build/0Harmony.dll` with a Harmony 2.0 build (or switch to a package reference) to use this flag. ## For SMAPI developers ### Compiling from source Using an official SMAPI release is recommended for most users, but you can compile from source directly if needed. There are no special steps (just open the project and compile), but SMAPI often uses the latest C# syntax. You may need the latest version of your IDE to compile it. SMAPI uses build configuration derived from the [crossplatform mod config](https://smapi.io/package/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 `SMAPI` project with debugging from Visual Studio (on macOS or Windows) will launch SMAPI with the debugger attached, so you can intercept errors and step through the code being executed. That 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](https://stardewvalleywiki.com/Modding:Modder_Guide/Test_and_Troubleshoot#Testing_on_all_platforms) on the wiki for the first-time setup. 1. [Install a separate 64-bit version of Stardew Valley](https://github.com/Steviegt6/Stardew64Installer#readme) on Windows. 2. Update the version numbers in `build/common.targets`, `Constants`, and the `manifest.json` for bundled mods. Make sure you use a [semantic version](https://semver.org). Recommended format: build type | format | example :--------- | :----------------------- | :------ dev build | `-alpha.` | `3.0.0-alpha.20171230` prerelease | `-beta.` | `3.0.0-beta.20171230` release | `` | `3.0.0` 3. In Windows: 1. Rebuild the solution with the _release_ solution configuration. 2. Back up the `bin/SMAPI installer` and `bin/SMAPI installer for developers` folders. 3. Edit `common.targets` and uncomment the Stardew Valley 64-bit section at the top. 4. Rebuild the solution again. 5. Rename the compiled `StardewModdingAPI.exe` file to `StardewModdingAPI-x64.exe`, and copy it into the `windows-install.dat` files from step ii. 6. Copy the folders from step ii to Linux/MacOS. 4. In Linux/macOS: 1. Rebuild the solution with the _release_ solution configuration. 2. Add the `windows-install.*` files from Windows to the `bin/SMAPI installer` and `bin/SMAPI installer for developers` folders compiled on Linux. 3. Rename the folders to `SMAPI installer` and `SMAPI installer for developers`. 4. Zip the two folders. ### Custom Harmony build SMAPI uses [a custom build of Harmony](https://github.com/Pathoschild/Harmony#readme), which is included in the `build` folder. To use a different build, just replace `0Harmony.dll` in that folder before compiling. ## Release notes See [release notes](../release-notes.md).
