Use bash syntax!** Examples: - ✅ `test -f file.txt && echo exists` - ✅ `ls -la | head -10` - ❌ `if exist file.txt (echo exists)` - This will NOT work **Actions:** - **prepare**: Run the one-time preparation (Prepare.bat) - **bash**: Run UNIX shell commands via busybox - **search**: Run code searches using `search_code.py` - **test**: Test this skill by running `test_search.bat` ## Routing Decision Check these patterns **in order** - first match wins: | Priority | Pattern | Example | Route | |----------|---------|---------|-------| | 1 | Empty or bare invocation | `se-dev-game-code` | Show this help | | 2 | Prepare keywords | `se-dev-game-code prepare`, `se-dev-game-code setup`, `se-dev-game-code init` | prepare | | 3 | Bash/shell keywords | `se-dev-game-code bash`, `se-dev-game-code grep`, `se-dev-game-code cat` | bash | | 4 | Search keywords | `se-dev-game-code search`, `se-dev-game-code find class`, `se-dev-game-code lookup` | search | | 5 | Test keywords | `se-dev-game-code test`, `se-dev-game-code verify`, `se-dev-game-code check` | test | ## Getting Started **⚠️ CRITICAL: Before running ANY commands, read [CommandExecution.md](CommandExecution.md) to avoid common mistakes that cause command failures.** If the `Prepare.DONE` file is missing in this folder, you MUST run the one-time preparation steps first. See the [prepare action](./actions/prepare.md). During preparation the current game version is stored into `CodeIndex/game_version.txt`. ## Essential Documentation - **[CommandExecution.md](CommandExecution.md)** - ⚠️ **READ THIS FIRST** - How to run commands correctly on Windows ## Code Search Documentation - **[QuickStart.md](QuickStart.md)** - More examples and quick reference - **[CodeSearch.md](CodeSearch.md)** - Complete guide to searching classes, methods, fields, etc. - **[HierarchySearch.md](HierarchySearch.md)** - Finding class/interface inheritance and implementations - **[Advanced.md](Advanced.md)** - Power user techniques for complex searches - **[Troubleshooting.md](Troubleshooting.md)** - What to do when searches return NO-MATCHES or too many results - **[Implementation.md](Implementation.md)** - Technical details for skill contributors (optional) ## Quick Search Examples ```bash # Find class declarations uv run search_code.py class declaration MyCubeBlock # Find method signatures uv run search_code.py method signature UpdateBeforeSimulation # Find class hierarchy uv run search_code.py class children MyTerminalBlock # Count results before viewing (useful for large result sets) uv run search_code.py class usage MyEntity --count # Limit number of results uv run search_code.py class usage MyEntity --limit 10 # Paginate through results uv run search_code.py class usage MyEntity --limit 10 --offset 0 uv run search_code.py class usage MyEntity --limit 10 --offset 20 ``` Always check the game code when: - You're unsure about the game's internal APIs and how to interface with them. - The inner workings of Space Engineers is unclear. ## Custom Scripting For building your own utility scripts to work with the indexes and decompiled code: - **[ScriptingGuide.md](ScriptingGuide.md)** - How to write Python scripts, use BusyBox, handle Windows paths ## Game Content Data The textual part of the game's `Content` is copied into the `Content` folder for free text search: - Language translations, including the string IDs - Block and other entity definitions - Default blueprints and scenarios - See [ContentTypes.md](ContentTypes.md) for the full list of content types ### Content Index `CodeIndex/content_index.csv` maps every textual content file to the decompiled C# source files that reference it. Columns: `rel_path` (path relative to `Content/`) and `usage` (path of a C# source file in `Decompiled/` that references it). Each content file appears once per usage, so you can filter and page by `rel_path` to see all C# code that loads or references a given content file. Files with no known usages have a single row with an empty `usage` column. ## General Rules - In the `Decompiled` folder search only inside the C# source files (*.cs) in general. If you work on transpiler or preloader patches, then also search in the IL code (*.il) files. - In the `Content` folder search the files appropriate for the task. See [ContentTypes.md](ContentTypes.md) for the list of types. - Do not search for decompiled game code outside the `Decompiled` folder which is at the same level as this skill file. The decompiled game source tree must be there if the preparation succeeded. - Do not search for game content data outside the `Content` folder which is at the same level as this skill file. The copied game content must be there if the preparation succeeded. ## Action References Follow the detailed instructions in: - [prepare action](./actions/prepare.md) - One-time preparation - [bash action](./actions/bash.md) - Running UNIX shell commands via busybox - [search action](./actions/search.md) - Running code searches - [test action](./actions/test.md) - Testing this skill ## Remarks The original source of this skill: https://github.com/viktor-ferenczi/se-dev-skills --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/viktor-ferenczi) — claim your Tome and manage your conversions.
