ssc
Summary
ssc is a basic, work-in-progress compiler for SunScript. It supports all of the byte-code functionality of Super Mario Sunshine's SPC interpreter. The compiler compiles to the SPC binary format (.sb files) used by Super Mario Sunshine.
This program utilizes the Grammatica library to generate an LL(k) parser using a grammar syntax file.
Usage
To use ssc, create an instance of the sunCompiler class.
Use the sunCompiler.Compile method or any of its overloads to compile a script:
| Parameter | Description |
|---|---|
name |
The name of the main script to compile. This is passed to the import resolver. |
output |
The output stream into which the compiled binary file will be written. |
binary |
The custom binary formatter to use for output. If not specified, the default SPC binary format will be used. |
resolver |
An instance of the import resolver to use. If not specified, sunImportResolver.Default will be used. |
ssc by default resolves imports by loading files on disk (see language.md for more information).
To use a custom import resolver, create a new class inheriting from sunImportResolver and pass an instance of it to the sunCompiler.Compile method.
The result of compilation will be returned in a sunCompilerResults instance.
Use the various properties on this type to gather the information of the compilation:
| Property | Description |
|---|---|
Success |
Whether the script was compiled successfully. If not, the Error property will be non-null. |
Error |
The fatal error which occured during compilation. If compilation was successful, this will be null. |
CompileTime |
The time it took to compile, measured as a TimeSpan instance. |
Data |
An array containing the data-table entries. |
Symbols |
An array containing the symbol-table entries. |
If the error is of the type sunSourceException, you can cast and retrieve the script name, line, and column of the error.
The repository comes with a ST3 syntax definition file:

Dependencies
There are several dependencies when building ssc. All dependencies must be placed in the lib-dir folder (see below), unless stated otherwise.
| Dependency | Notes |
|---|---|
| arookas library | Preferably, the library should be built in the same configuration as ssc (e.g. debug, release). |
| Grammatica 1.6 | Already included in the repository. |
Note: A Java runtime compatible with JDK 1.5 is required for generating the Grammatica parser classes during compilation. For more information, see Grammatica's official installation documentation.
premake
This repository contains a premake5 configuration file. The script generates a solution with the following projects:
- ssc, the base ssc API library
- frontend, a basic command-line frontend
- sbdump, a tool which dumps disassembly and other information on compiled SPC binaries
After setting up the dependencies, simply run the script through premake5 and build the resulting solution. There are also options which are able to be configured via the premake5 command line:
| Option | Description |
|---|---|
| lib-dir | Sets the path to the dependencies. Defaults to the lib/ folder. |
| clean-functions | Compiles only used functions. |
| clean-symbols | Cleans symbol table of unused symbols. |
Language
For more information on the SunScript language and its syntax, see language.md.
Extending the compiler
ssc is designed to be extensible. For more information on extending ssc, see extensions.md.
