← [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/Mac, 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/Mac 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 on Windows for players on Windows. Set automatically in `crossplatform.targets`. `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 Mac 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. 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.2` release | `` | `3.0.0` 2. In Windows: 1. Rebuild the solution in Release mode. 2. Copy `windows-install.*` from `bin/SMAPI installer` and `bin/SMAPI installer for developers` to Linux/Mac. 3. In Linux/Mac: 1. Rebuild the solution in Release mode. 2. Add the `windows-install.*` files to the `bin/SMAPI installer` and `bin/SMAPI installer for developers` folders. 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. ## Release notes See [release notes](../release-notes.md).
