Man, I hate writing documentation. I feel like this should be on a wiki
instead, but fuck creating one right now.

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.
DataCount The total number of data-table entries created.
SymbolCount The total number of symbols (builtins, functions, and variables) created.
BuiltinCount The total number of builtin symbols created.
FunctionCount The total number of function symbols created.
VariableCount The total number of global-scope variable symbols created.

If the error is of the type sunSourceException, you can cast and retrieve the script name, line, and column of the error.

Compiling

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

Simply run the script through premake5 and build the resulting solution. There are also compile-time options which are able to be configured via the premake5 command line:

Option Description
clean-symbols Cleans symbol table of unused symbols.

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.

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.
