Class Compiler

java.lang.Object

convex.core.lang.Compiler

public class Compiler
extends Object

Compiler class responsible for transforming forms (code as data) into an Op tree for execution. Phases in complete evaluation:

1. Expansion (form -> AST)
2. Compile (AST -> op)
3. Execute (op -> result)

Expanded form follows certain rules: - No remaining macros / expanders in leading list positions TODO: consider including typechecking in expansion phase as per: http://www.ccs.neu.edu/home/stchang/pubs/ckg-popl2017.pdf "A language that doesn't affect the way you think about programming is not worth knowing." ― Alan Perlis

Field Details

INITIAL_EXPANDER

public static final AFn<ACell> INITIAL_EXPANDER

Initial expander used for expansion of forms prior to compilation. Should work on both raw forms and syntax objects. Follows the "Expansion-Passing Style" approach of Dybvig, Friedman, and Haynes

QUOTE_EXPANDER

public static final AFn<ACell> QUOTE_EXPANDER

Expander used for expansion of `quote` forms. Should work on both raw forms and syntax objects. Follows the "Expansion-Passing Style" approach of Dybvig, Friedman, and Haynes

QUASIQUOTE_EXPANDER

public static final AFn<ACell> QUASIQUOTE_EXPANDER

Expander used for expansion of `quasiquote` forms. Should work on both raw forms and syntax objects. Follows the "Expansion-Passing Style" approach of Dybvig, Friedman, and Haynes
