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.
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 several compile-time options which are able to be configured via the premake5 command line:

Option	Description
var-alloc	Affects how variables are allocated slices. Available values are pack and inc.
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.
