The Visible Compiler

These structures provides access to "The Visible Compiler" of Standard ML of New Jersey. Individual modules that control the major phases of compilation can be accessed in a type-safe way by user programs. In this way such utilities as the Compilation Manager can be implemented outside of the compiler itself.

Description

structure Stats
Utilities for statistics gathering about compiler phases.

structure Control
Allows parameters of the compiler and interactive system to be tweaked in a simple way.

structure PrettyPrint
Provides services to user programs that want to do Oppen-style pretty printing.

install_pp l f
The user defines a datatype d, whose full symbolic pathname is (e.g.) MyStruct.Substruct.d, then defines a prettyprinter 
               dp : ppstream -> d -> unit
over d, perhaps using the Oppen primitives. Then dp is installed in the pp-table via 
	      install_pp ["MyStruct","Substruct","d"] dp
Subsequently, when a value of type d comes to be printed out, the interactive system uses dp for displaying the value, instead of using the default datatype prettyprinter.

structure Compiler

version
Tells which version of SML/NJ is running. system is typically "Standard ML of New Jersey", version_id tells major and minor version numbers, and date is spelled out in English.

architecture
A short identifier for the instruction-set architecture on which the system is running.
